The Truth About Cavity Wall Ventilation

Let’s delve into the frequently misunderstood topic of cavity wall ventilation. Hosted by Roger Bisby from the Skill Builder channel, this discussion addresses one of the most common questions homeowners and builders face: Should cavity walls be ventilated, or is sealing them a better option?

Cavity walls are a crucial component of modern home construction, designed to prevent water penetration by creating a barrier that allows rainwater to drain harmlessly to the ground. However, adding insulation and air bricks has created confusion about whether cavities require ventilation to “breathe.”

Roger debunks misconceptions, such as the belief that air bricks ventilate the cavity. Instead, he clarifies their role in ventilating subfloor spaces or providing direct airflow into rooms. He also explains the importance of sealing the top of the cavity to prevent issues like loft condensation caused by evaporating dampness from open cavities.

The video highlights how a sealed cavity improves insulation performance. Eliminating air movement makes trapped air within the cavity a natural insulator, enhancing energy efficiency and reducing heat loss. Practical advice includes using mastic or silicone to seal gaps around windows, doors, and other openings, ensuring maximum insulation value—even without additional cavity wall insulation.

Whether you’re a homeowner looking to improve your property’s insulation or a professional seeking clarity on best practices, this video provides straightforward, actionable guidance on cavity wall ventilation. With over 1,000 home building and renovation videos, the Skill Builder channel is your go-to source for tackling common construction challenges.

Cavity Wall Ventilation – What You Need To Know
  • Purpose of Cavity Walls: The primary function of cavity walls is to stop water penetration by allowing rain to run down the cavity and soak into the ground.
  • Common Misconceptions: Air bricks are often misunderstood; they ventilate the subfloor space, not the cavity itself.

❌ Sealing Is Key: Open cavities can lead to condensation issues in the loft due to evaporation. Proper sealing prevents air movement, improving insulation.

  • Insulation Benefits: Trapped air within a sealed cavity acts as a natural insulator, enhancing energy efficiency.
  • Practical Advice: Seal gaps around windows, doors, and air bricks using mastic or silicone to optimize the cavity’s insulation.

How to Stop Damp in Your Home: A Comprehensive Guide

Damp issues can wreak havoc on homes, particularly in basements and below-ground areas where moisture is most persistent. Addressing dampness effectively requires careful preparation, the right materials, and a thorough application process. This article explores proven strategies to stop damp for good, based on techniques demonstrated in the video, The Easiest Way To Stop Damp For Good.

Step 1: Preparing the Wall Surface

The first step to stop damp is ensuring a smooth and stable surface. Applying a straightening coat of render is essential to create a flat base. This eliminates any unevenness that could compromise the adhesion of waterproofing materials. For walls with rough brickwork or paint, levelling out the surface is critical to prevent water ingress through gaps or weak points.

Step 2: Applying Polymer-Reinforced Waterproofing

A key innovation to stop damp, is using polymer-reinforced cementitious coatings, such as Safeguard TS+. These coatings are specially designed for below-ground applications. The polymer binds the cement, prevents micro-cracking, and creates a microporous layer that repels water, allowing the wall to “breathe.” This property is crucial for managing trapped moisture and reducing the risk of future damp issues.

The application involves two coats, with 2 to 4 hours of drying between each coat. The colour change from blue to brown indicates readiness for the second coat, ensuring complete coverage and long-term protection.

Step 3: Choosing Advanced Solutions for Severe Cases

In cases of significant water penetration, membrane systems offer an alternative to tanking slurries. These systems create a cavity behind the membrane for moisture to drain into a channel, which can be pumped out. This approach is ideal for basements facing persistent or high-volume water intrusion.

Step 4: Using Breathable Materials for Finishing

For finishing, high lime plaster is an excellent choice. Its breathability allows it to absorb and release condensation, acting as a buffer for moisture. This makes it particularly suitable for damp-prone areas. Additionally, it resists salt ingress, preventing surface deterioration.

Effective damp-proofing requires careful preparation, advanced materials, and the right techniques. Whether using tanking slurries, membrane systems, or breathable plasters, each method addresses specific challenges. Following these steps, homeowners can safeguard their properties and ensure a dry, durable living space.

Outdoor spaces serve as an extension of our homes, providing a sanctuary for relaxation and creativity. Imagine stepping into a garden that reflects your personality and style, where every element is carefully chosen to enhance its beauty and functionality.

Many homeowners overlook the potential of their gardens, settling for basic layouts. By incorporating innovative design ideas, you can transform your outdoor space into a stunning haven, that captivates and inspires.

Exploring Unique Elements to Elevate Your Garden

A garden should be more than just a patch of grass; it should reflect your individual taste and lifestyle. Enhance your outdoor area by introducing vertical gardens, water features, or artistic sculptures.

Vertical gardens use vertical space and can add a vibrant splash of greenery, especially in smaller areas. They can be tailored to your preferences with various plants that bloom at different times of the year, ensuring continuous interest.

Water features like fountains or small ponds introduce tranquil sounds and attract wildlife, creating a peaceful atmosphere. Consider installing a small pond with aquatic plants and fish, which can become a focal point in your garden.

Incorporating art—whether through sculptures, decorative stones, or even murals—adds a personal touch and sparks conversation. Each element brings a new dimension to your garden, inviting exploration and admiration.

Designing Functional Zones

When planning your outdoor space, consider creating functional zones that cater to various activities. Define areas for relaxation, dining, gardening, or play.

For instance, designate a comfortable seating area with outdoor furniture to unwind with a book or enjoy tea. Use outdoor rugs and cushions to define this space and make it feel inviting.

A dining area with a table and chairs can be a perfect gathering spot for those who love entertaining. Enhance this zone with a pergola or shade sails to provide cover and create an intimate atmosphere.

To further define these spaces, consider incorporating decorative fence panels. These panels can act as visual dividers, adding structure and style while helping delineate your garden’s different areas.

If you have children or pets, consider incorporating a play zone with safe, soft surfaces and engaging activities like a sandbox or a small climbing structure. Dividing your garden into functional zones improves usability and adds visual interest, making the space feel more dynamic and thoughtfully designed.

Harnessing the Power of Lighting

Lighting plays a crucial role in garden design, transforming the mood and usability of outdoor spaces. By thoughtfully integrating various lighting options, you can extend the usability of your garden into the evening hours.

String lights hung across seating areas create a whimsical ambience. Meanwhile, pathway lights can guide visitors safely through your outdoor space.

Consider using solar-powered lights for an eco-friendly option that requires minimal maintenance. These lights absorb sunlight during the day and illuminate your garden at night without increasing your electricity bill.

Additionally, incorporating spotlights on key features—such as trees, plants, or architectural elements—can enhance their beauty and draw attention to your garden’s unique aspects.

For a modern touch, consider installing smart lighting systems. These allow you to control the brightness and colour of your lights through an app. This flexibility can help set the perfect mood for any occasion, whether a quiet evening or a lively gathering.

Incorporating Sustainable Practices in Your Design

Sustainable practices are increasingly important in outdoor space design. Homeowners seek ways to reduce their environmental impact while creating beautiful outdoor spaces.

One innovative approach is to incorporate native plants adapted to local climates, which require less water and maintenance. Native species support local wildlife by providing food and habitat for pollinators, contributing to biodiversity.

Rain gardens can also be a fantastic addition. They allow you to manage stormwater runoff while creating a stunning feature. These gardens are designed to capture and filter rainwater, helping to reduce erosion and improve water quality.

Using permeable paving materials for pathways and patios can further enhance sustainability. These materials allow rainwater to seep through and recharge the groundwater.

Additionally, consider composting organic waste and utilising recycled materials in your garden. For instance, reclaimed wood can be used for raised garden beds or furniture. This gives new life to materials while adding character to your outdoor space.

Personalising Your Outdoor Experience

At the heart of transforming your outdoor space is the desire to create a personal oasis tailored to your needs and preferences. Consider your lifestyle and how you plan to use your garden.

If you enjoy entertaining, design spaces for gatherings with comfortable seating and outdoor dining areas. An outdoor kitchen with a grill and prep space can elevate your hosting game, allowing you to prepare meals while enjoying the fresh air.

If relaxation is your priority, incorporate hammocks or secluded nooks with comfortable seating. Consider adding a fire pit surrounded by loungers, perfect for cooler evenings when you want to gather with friends or family.

Including features like outdoor speakers can enhance your experience, allowing you to enjoy your favourite music while spending time outside.

Incorporating personal elements—such as family heirlooms, handmade decorations, or plants with sentimental value—can further enhance your garden’s uniqueness. By personalising your garden design, you ensure that it meets both aesthetic goals and practical needs, making it a truly enjoyable retreat.

Addressing Damp Problems with Practical Solutions

Damp problems are a common concern for homeowners, with many rushing to costly remedies without fully understanding the root cause. Surprisingly, most of these issues stem not from structural defects but from condensation—a manageable and often overlooked problem. By addressing the basics of humidity control, homeowners can save money and protect their property.

Understanding Condensation

Condensation occurs when warm air laden with moisture comes into contact with cooler surfaces, such as walls or windows, causing water to accumulate. This phenomenon is frequently mistaken for structural dampness, leading to unnecessary expenses on damp-proofing measures that fail to resolve the problem.

Monitoring Humidity Levels

A simple, affordable solution lies in measuring humidity levels within the home. For as little as £5, a small humidity sensor can provide valuable insights into whether a household is at risk. Ideally, relative humidity levels should stay below 60%. Prolonged exposure to higher levels encourages mould growth, damaging walls, furniture, and health.

Cost-Effective Solutions

Investing in a dehumidifier can provide immediate relief if high humidity is detected. These devices create a healthier indoor environment by removing excess moisture from the air. Additionally, improving ventilation—by opening windows or using extractor fans—can drastically reduce condensation buildup.

Observational Techniques

Homeowners are encouraged to check each room’s humidity levels, as conditions can vary significantly within the same property. For instance, seldom-used rooms may retain lower humidity due to natural drafts, as demonstrated with single-glazed sash windows. Contrary to modern practices, such ventilation can be beneficial.

Assess your home’s humidity before committing to expensive treatments. By addressing condensation with affordable tools and methods, you can resolve damp problems efficiently and sustainably, ensuring your home remains a comfortable and healthy space.

Guide: Fixing Dead Zones in Underfloor Heating

This guide provides a step-by-step approach to diagnosing and resolving dead zones in an underfloor heating system.

Step 1: Identifying the Problem

To detect cold spots in your underfloor heating system, walk barefoot over the flooring to sense any uneven warmth. For a more precise identification, use a thermal imaging camera, such as a plug-in device for phones, to map the pipe temperatures visually.

Step 2: Diagnosing Airlocks

Airlocks often cause inconsistent heating in one or more circuits. These issues are more likely to occur in systems with manifolds installed at uneven levels. To prevent airlocks, position the manifold higher than the underfloor circuits if possible, and ensure the system is vented properly during installation.

Step 3: Flushing the System

Locate the manifold valves to prepare for flushing. The fill valve, usually at the top, introduces water, while the drain valve at the bottom expels air or debris. Attach a garden hose to the fill valve for high-pressure water input and a drain hose to the bottom valve to flush out debris. One at a time, flush each circuit to clear any airlocks, sediment & fix any dead zones.

Step 4: Using Boiler Pressure

Open the boiler’s fill valve to pressurise the system as an efficient alternative to using hoses. Close off all circuits except one, and let the water flow through that circuit. Repeat the process for all circuits to ensure they are completely debris-free.

Step 5: Adjusting Flow Rates

After flushing, restore balance in your heating system by resetting the flow rates for each circuit. Consult your recorded flow rate settings and adjust the valves to achieve a consistent flow rate of approximately 2 litres per minute per circuit or as specified for your system.

Step 6: Maintenance Tips

To maintain your underfloor heating system, flush it every few years to remove buildup and sediment. After flushing, add an inhibitor solution to prevent corrosion and sludge formation. Regularly monitor the flow meters to ensure consistent heating across all circuits and avoid dead zones.

Why and When to Power Flush Your Heating System

A power flush is an essential maintenance procedure for central heating systems, designed to remove sludge, rust, and other debris from pipes, radiators, and boilers. Over time, these deposits can accumulate, reducing the efficiency of your heating system and potentially causing blockages or damage.

A power flush helps restore the system’s efficiency, improve heat distribution, and prolong the life of your boiler.

You should consider it if you notice cold spots on your radiators, noisy pipes, or an overall drop in heating performance. It’s also a good idea to install a new boiler to ensure the existing system is free from debris that could damage the new equipment.

In areas with hard water or systems prone to sludge buildup, regular flushing is recommended every 5-6 years.

Caution with DIY Power Flush

While attempting a DIY powerflush to save money may be tempting, it’s not as straightforward as it seems.

A proper power flush requires specialist equipment, such as a professional-grade pump, which can be expensive to hire.

Moreover, you’ll need to understand your heating system’s layout to avoid causing damage.

Improper techniques, excessive pressure, or leaving valves in the wrong position could lead to leaks, burst pipes, or damage to your boiler.

Older systems, in particular, are vulnerable, as the process can dislodge rust, which might create more problems.

For DIY enthusiasts, using a chemical flush or installing a magnetic filter may be safer alternatives. If you’re determined to do a full power flush yourself, research thoroughly and proceed cautiously.

However, hiring a professional ensures the job is done safely, efficiently, and with the right tools. In most cases, it’s worth the investment for peace of mind.

London’s Gas Streetlights: A Glimpse into the Past

Gas streetlights, iconic symbols of the city of London’s historic charm, have illuminated its streets since the early 19th century. Introduced in 1807 along Pall Mall, gas lighting revolutionised urban life, improving safety and extending activity after dark. By the mid-19th century, thousands of gas lamps lit up the city, becoming integral to London’s Victorian identity.

The gas lamps were initially powered by coal gas, a by-product of coal carbonisation. Lamplighters used long poles to manually light and extinguish each lamp, a task that required precision and routine. With their distinctive uniforms, these lamplighters became familiar figures in London’s streetscape. Over time, innovations such as clockwork mechanisms and pilot lights reduced the need for manual operation.

Today, an estimated 1,500 gas streetlights remain in London, preserved as functional monuments to a bygone era. These lamps, often found in areas like Covent Garden, Westminster, and the Royal Parks, continue to evoke the romance of Dickensian London. They are lovingly maintained by a small team of skilled engineers, ensuring they remain operational despite the encroachment of modern electric lighting.

Beyond their historical significance, London’s gas lamps are celebrated for their unique aesthetic. Their soft, warm glow creates a nostalgic ambience that contrasts sharply with the starkness of LED lighting. For residents and visitors alike, they serve as tangible links to a time when gaslight transformed the cityscape and brought new possibilities to nocturnal life.

Efforts to preserve these lamps highlight their cultural importance. Campaigns and heritage initiatives aim to protect these remnants of London’s industrial history, recognising them as symbols of the city’s resilience and innovation. The gas streetlights of London are not just functional objects but enduring artefacts of the city’s rich and layered past.

Plaster Patching Repair

Plaster patching repairs are common in UK homes, particularly in older properties where wear and tear or previous repairs have failed. Whether a small dent in the wall or a larger area of damaged plaster, using suitable materials ensures a lasting and professional finish. In this guide, we’re using Dryzone Hi-Lime Renovation Plaster from Safeguard Europe, a versatile and breathable plaster ideal for patchwork in traditional and modern homes.

Hi-Lime Renovation Plaster is particularly suitable for UK properties with solid walls that require a breathable repair material. Traditional gypsum plasters can trap moisture, causing damp issues in heritage buildings or walls that need to “breathe.” Hi-Lime, on the other hand, is a high-quality lime-based plaster that accommodates the needs of these walls while delivering a smooth finish.

Preparing for Plaster Patching
Start by removing loose or damaged plaster from the area, ensuring the repair edges are neat. Clean the substrate to remove any dust, grease, or contaminants. If the underlying surface is highly absorbent, dampen it slightly to prevent the plaster from drying too quickly.
Applying Hi-Lime Renovation Plaster

Mix the Hi-Lime Renovation Plaster according to the manufacturer’s instructions, ensuring a consistent, lump-free texture. Apply the plaster in thin layers using a plastering trowel, pressing firmly to achieve good adhesion. Build up the plaster in layers for deeper repairs, allowing each one to dry partially before adding the next.

Finishing Touches

Once the plaster has dried, it can be sanded lightly to blend seamlessly with the surrounding wall. Because Hi-Lime is breathable, it’s an excellent base for finishing with breathable paints or lime washes.

It Is Essential To Prevent Wall Collapses

Wall collapses within the building trade are a serious safety concern, often resulting from inadequate planning, poor construction practices, or external environmental factors. They can occur during construction, renovation, or demolition, and they pose significant risks to workers and nearby structures.

Platipus Earth Anchoring Systems prevent wall collapses effectively, particularly in scenarios involving retaining walls, sheet piles, and temporary excavation supports. These systems utilise Percussion Driven Earth Anchors (PDEA®), which are post-tensioned to provide immediate stabilisation against lateral pressures such as soil loads and hydrostatic forces.

How Platipus Systems Help Prevent Wall Collapses :
  1. Reinforcement of Retaining Structures:
    • Retaining walls are supported by anchoring systems that counteract the forces exerted by the retained soil.
  • Platipus anchors are used as tiebacks, creating a cost-effective and durable solution that resists overturning and sliding forces

Temporary Excavation Support:

    • Excavations, especially in unstable or loose soils, require reinforcement to prevent wall collapse during construction.
    • Platipus systems are ideal for these temporary conditions, providing quick and reliable anchoring with minimal soil disturbance

Load-Locking Mechanism:

The anchors are driven into the soil and tensioned to a pre-determined load, ensuring the wall is stabilised immediately upon installation.

    • This minimises movement or shifting that could lead to failure

Managing Hydrostatic Pressure:

    • Their Plati-Drain® system can alleviate hydrostatic pressure behind walls by providing drainage while maintaining anchoring strength. This is critical for retaining walls and slopes, as water buildup is a common cause of failure

Adaptability to Soil Types:

    • The anchors perform well in granular soils, cohesive soils, and mixed conditions, making them versatile for projects in different environments

Key Features:

  • Minimal installation time and disturbance.
  • Corrosion-resistant materials ensure long-term durability.
  • Real-time load testing ensures the anchoring system meets the design specifications

Platipus systems are widely used in civil engineering projects to reinforce retaining walls and excavation supports, making them a trusted choice for preventing wall collapses under various conditions. For further technical details, their official resources provide comprehensive guidance.

What Is A Housing Crisis?

The Uk Housing crisis refers to a long-standing and multifaceted issue characterised by a mismatch between housing demand and supply, leading to problems with affordability, availability, and quality of housing. The crisis affects millions of people across the country, and its roots lie in decades of underinvestment in housing, economic factors, and population growth.

What are Structural Insulated Panels (SIPs)

sips.org/what-are-sips

Structural insulated panels (SIPs) are a high-performance building system for residential and light commercial construction. The panels have an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). The result is an extremely strong, energy-efficient, and cost-effective building system.

WALL-HUNG TOILET FITTING STEPS

Prep the Wall and Space: Begin by checking the wall where the toilet will be mounted. Make sure all necessary connections (water and waste pipes) are in place and correctly aligned.

Add Silicon to Flush Pipe: Apply a small amount of silicon to the flush pipe connection to ensure it fits snugly. This helps reduce friction and prevents leaks. A small pot of silicon (though costly) is recommended for a secure fit.

Adjust Pipe Length: Measure and trim the pipe carefully to ensure it fits precisely. Roger recommends subtracting around 8mm from the measurement to avoid future issues when tightening the pan to the wall. Trim slightly more if necessary to prevent the pipe from dislodging when pressure is applied.

Remove Burs: After cutting the pipe, file down any rough edges or burs, especially on the inside. Use a small file or knife to smooth the surface completely to avoid damaging the connection.

Test Fit the Pipe: Insert the pipe into the fitting to ensure it goes in smoothly and aligns correctly with the toilet. Mark where the pipe meets the tile to help with placement.

Position the Studs and Grub Screws: Measure the distance from the wall (usually around 35mm) and install the studs accordingly. Place the grub screws into position, and as you adjust them, they’ll pull the pan snugly toward the wall.

Final Adjustments: Insert the Allen keys into the grub screws to tighten the pan. Once the pan is levelled and stable, apply a final bead of silicon along the back edge to keep it securely in place.

Inspect for Stability: Check that the toilet is mounted securely and aligned perfectly with the wall. If everything looks good, your wall-hung toilet is ready for use!

Birkdale has released its new DuraPost Commercial Reflective Acoustic Fencing. An ideal solution for both commercial and residential applications, that require effective noise reduction. The robust and reflective fencing offers a sound reduction of 27dB, which has been tested to, and complies with BS EN 1793-2:2018.

The fencing system is built using Birkdale’s Commercial DuraPosts. These are manufactured from cold rolled pre-galvanised steel, combined with tongue and groove reflective acoustic timber boards, and rubber acoustic seals.

The acoustic timber boards are made from 70% PEFC Certified 225mm x 47mm slow-grown redwood, which is highly durable and resistant to decay.

Due to its slow growth, the redwood contains tight growth rings, denser wood fibres and fewer knots. This contributes to improved strength, stability and quality.

The rubber seal strips, which are inserted within the DuraPost profile at both ends of the panel – to create a compressed seal within the bays, is made from Cellular Adhesive EPDM Sponge. This provides excellent air, water, UV and weathering resistance from -40 to +80° C.

As an optional extra, the fencing system can also be fitted with Whisper Cellular Acoustic Foam to bring the noise reduction up to the full 27dB. This is easily fitted to one side of the fence and held in place using an ‘S’ profile wire mesh.
