Bradfords Launches Training for Sustainability Champions

Bradfords Building Supplies has teamed up with a range of organisations, who are leading the way in environmental responsibility in the built environment, to train its new team of Sustainability Champions.

Marshalls, Xtratherm, Polypipe, Millboard and Timloc led presentations and discussions on a range of topics at an intensive training session.

Challenging the Champions to think differently about products that might appear to be sustainable choices at only face value, there was also a focus on designing resilient spaces with a long-term view in mind as well as the importance of a systems approach to making a building more energy-efficient.

In addition, Bradfords’ Head of Transport, Martin Caddick and Head of Facilities, Donal Ryan, updated the Champions on the company’s own efforts to drive down its energy consumption, carbon emissions and waste.

“Our Sustainability Champions volunteered from across our network to help deliver Bradfords’ environmental sustainability strategy by engaging with fellow employees at department or branch level and to support our customers in considering environmentally friendly options for their projects.

Our training day was an effective way to get them started on that journey,†said Giles Bradford, Head of Sustainability at Bradfords.

“There was a real spirit of collaboration and our Champions engaged enthusiastically with what can be a very complex and challenging range of issues.

“Our suppliers also provided a real ray of hope and inspiration, demonstrating the impressive inroads they are already making in environmental sustainability.

“We have made a substantial step forward in our goal to be able to best support our customers in building the sustainable communities of the future.â€

Nick Weeks, Assistant Branch Manager at Bradfords in Sherborne, was among the Champions taking part.

He has been inspired to trial new eco-friendly alternative solutions to more traditional sealant and adhesive plastic tubes in his branch.

He said: “This really made me think about how we make sure the sustainability credentials of what we sell are visible in our branch. That’s what will start the conversations we need to be having.â€

Evan Morgan, Civils Sales Specialist at Bradfords’ Cinderford branch, added: “I was really encouraged to hear just how committed Bradfords is to reducing its carbon emissions, from only using green energy suppliers to a pledge to switch our car fleet to low emissions vehicles, and conversion to 25% of our forklifts being electric this year.â€

Bradfords’ Sustainability Champions have been chosen for their commitment and enthusiasm for the cause and are spread across various roles and branch locations.

Plasterboard — Why All The Colours?

Why are there so many different types of plasterboard? Roger explains.

What types of plasterboard are there?

Moisture-resistant plasterboard

In the core of moisture-resistant plasterboard are some additives which repel moisture. These plasterboards are the only suitable plasterboards for kitchens and bathrooms as the humid environment will otherwise decay the quality of the board over time and can result in loss of effectiveness of any insulating properties. Using non-moisture-resistant plasterboard in a moist area will lead to damp, rot and mould over time.

Acoustic plasterboard

Opt for acoustic plasterboard and you’ll get additional benefits over just being able to finish off the room. Acoustic plasterboard will keep the sound out of the room and reduce how noise travels between rooms to give a more private and comfortable life for those living there. Utilising acoustic plasterboard in a living room refurbishment, for example, will mean that a loud movie won’t disrupt a quiet chat in the kitchen.

Damp Proof Foil Backed plasterboard

Damp-proof plasterboard is equipped with a layer of foil attached to one side. It can be used in environments that are associated with an appreciable level of moisture (such as kitchens).

Fire-resistant plasterboard

Fire-resistant plasterboard does exactly what it says on the tin. It’s important to become familiar with and choose the right fire performance rating as each rating denotes a different thing. Some fire-resistant plasterboard may be non-combustible, whereas some may offer 240 minutes of fire resistance before it will catch fire. If fire-resistant plasterboard isn’t specified and is just an optional extra, it’s worth choosing what suits your application best. If it’s specified then pick the correct performance rating to meet building regulations.

Insulated plasterboard

Insulated plasterboard is a favourite amongst dry liners as it’s so easy to install. It’s essentially a piece of insulation board faced with plasterboard but the fact that they’re already bonded together and ready to go makes the process faster and more efficient than if you were installing a layer of insulation and then plasterboard. Just like regular plasterboard, this type can be finished without plastering over too.

Parapet Walls — Are They A Good Idea?
Parapet Walls

Roger investigates the pros and cons…

Parapet walls are low walls that extend above the edge of a roof, balcony, or terrace. They can be purely decorative, but often serve practical purposes like providing safety barriers, concealing roof elements, or controlling water runoff. In addition, they can help with fire protection by preventing flames from spreading between buildings. They’re often found in both historic and modern architecture.

Spray Foam Insulation — The Ugly Truth?
Spray foam insulation in your house..

Roger explains the pros and cons.

Spray foam insulation explained by the Which? Team.

Also called spray polyurethane foam (SPF), it is an alternative to traditional building insulation.

It’s versatile and can be used to insulate your roof, loft, walls and floor, helping to retain warmth and reduce energy costs.

PROS AND CONS

Spray foam insulation offers a number of benefits, such as:

✔ It can be applied in difficult-to-reach areas.

✔ In some cases, it can provide additional soundproofing.

However, there are also some significant drawbacks to consider, such as:

✖ It’s more expensive than other types of insulation.

✖ It needs to be installed by a professional.

✖ It can be difficult to remove once it’s been installed.

✖ Potentially reduces ventilation within the roof space, causing humidity and dampness; placing roof timbers at risk of decay.

✖ Harmful fumes are given off during installation.

✖ It shouldn’t be used in listed buildings or houses with thatched roofs.

✖ It’s often ugly, messy and can’t be decorated over.

✖ It can affect the value of your property.

✖ It may prevent buyers from getting a mortgage.

We’d strongly advise getting specialist advice from an expert or two in this area and proceeding with caution.

What is spray foam insulation?

Spray foam insulation is a liquid foam that is sprayed into position and sets into an insulating layer.

It can be used to insulate your roof, loft, walls, floors and more. It has been in use for more than 30 years and is now becoming increasingly popular as it’s an effective insulator and can also stop air leakage.

There are two types of spray foam insulation to choose from. Closed-cell spray foam Open cell spray foam. If spray foam insulation is right for your home and budget, the type you choose will depend on what you want it to do.

If you’re looking to insulate your loft, the Which dedicated guide explains the different types of loft insulation.

How Do Heated Jackets Actually Work?

Heated jackets work similarly to heated blankets and heated car seats. During assembly, the back of each jacket is lined with an electronically powered copper heating zone, powered by a battery pack that sits within an inside pocket. They’re toggled on and off via a small temperature control inside the jacket.

Are Heated Jackets Safe?

Yes. Heated jackets are safe, though scepticism on their safety is reasonable as water and electricity don’t make for a healthy combination. If the jacket were to somehow get wet inside the lining, we would advise taking the jacket off and disconnecting the battery immediately, though getting wet won’t damage the jacket.

The temperature control embedded within the jacket is waterproof, and you can even wash the jacket in your washing machine as long as the USB battery is removed before washing. It’s also worth noting that you should not use a heated jacket if you suffer from a serious illness or chronic health condition such as heart disease, anaemia, low blood pressure, paralysis, hypertension, diabetes or any other condition that causes poor circulation.

What About Overheating?

Our heated jackets have an internal thermostat so that they only heat up to the desired temperature setting you have set it to. However, if the temperature were to exceed this setting for any reason, there’s a built-in safety cut-out that will turn the jacket off immediately.

Tool Theft Fight Back — Home Office Responds

Tool Theft Fight Back — Home Office Responds

 

Tool theft – A growing concern

The impact of tool theft is not just financial; it disrupts work, delays projects, and can result in significant inconvenience. Thieves target tools due to their high resale value and portability. To protect against tool theft, it’s essential to use secure storage solutions, such as lockable sheds or toolboxes, and to invest in vehicle security measures. Additionally, marking tools with identifiable information and keeping a detailed inventory can aid in recovery if theft occurs. Enhancing security awareness and taking preventive measures can significantly reduce the risk of tool theft and its associated problems.

HOME OFFICE RESPONSE

The Government is tackling acquisitive crime as a priority and is committed to reducing the ability for criminals to profit from stolen goods. The Beating Crime Plan, published in July 2021, sets out the Government’s strategy for cutting crime, protecting the law-abiding majority and making neighbourhoods safe. The Government is aware of the significant impact the theft of tools can have on victims, particularly those who rely on their tools to earn a living, and the Beating Crime Plan recognises the economic damage caused by crime and the need to cut crime to enable businesses to thrive.

The Home Office has established an expert Stolen Goods Working Group consisting of policing and academic partners who are taking forward work across a number of themes. These include actions to identify where and how stolen goods are sold; examining ways to ensure property is marked, identifiable and traceable; and exploring ways to encourage increased enforcement from police and due diligence checks by second-hand goods traders.

The Home Office is also working closely with the police and motor and insurance industry representatives through a National Vehicle Crime Working Group to take forward a programme of work to tackle vehicle-related theft. This includes consideration of how to effectively prevent and deter theft from vehicles, including vans. We are also working to help police forces increase the knowledge and skills of their officers. A network of vehicle crime specialists has been established across each police force in England and Wales, to ensure forces share information about emerging trends to better tackle regional issues.

To ensure the police have the resources they need to tackle crime, the Government is recruiting an additional 20,000 police officers by March 2023. As at 30 September 2021, the police have recruited an additional 11,053 officers towards the uplift. Furthermore, the Safer Streets Fund – the Government’s flagship crime prevention programme – is supporting areas across England and Wales disproportionately affected by acquisitive crimes, such as burglary and theft, to invest in proven crime prevention measures including street lighting, CCTV, and ANPR cameras.

The Government has invested £45 million across the first two rounds of funding and details for future Safer Streets funding will be announced in due course.

We note the assertion that the sentence for handling stolen goods has been downgraded, and we can reassure you this is not the case. Under the Theft Act 1968, those who steal property such as tools could face a maximum penalty of seven years’ imprisonment if convicted, and those convicted of handling stolen goods could face a maximum penalty of 14 years’ imprisonment. When determining an appropriate sentence, a court may consider the additional negative impact on victims when the property stolen is relied upon to earn a living.

The Sentencing Guidelines for theft, published by the independent Sentencing Council, require courts to assess the level of harm caused when determining the offence category. This includes consideration of the financial loss experienced and any additional significant harm suffered by the victims or others, such as if the items stolen were of substantial value to the owner – regardless of monetary worth, the impact of theft on a business, if a high level of inconvenience was caused to the victim or others, and if there was consequential financial harm to the victim or others. The list is non-exhaustive, so the court may consider any other aggravating factors deemed relevant, increasing the seriousness of an offence.

We note the concerns about stolen tools being openly sold and the suggestion that sellers should be challenged to prove ownership. There must be sufficient evidence and suspicion to request details of ownership from sellers. That is why it is important for tools to be appropriately marked and registered on a property database; this provides a basis from which police can conduct the necessary checks to identify stolen goods, verify ownership via the third-party database, and return to rightful owners.

There are other practical steps owners can take to protect their property, such as not leaving tools in vans overnight, upgrading locks, and installing alarms. The Police Crime Prevention Initiatives (PCPI) is a not-for-profit, police-owned organisation that works on behalf of Police and Crime Commissioners and Chief Constables to deliver crime prevention and reduction initiatives across the UK. It also provides crime prevention advice:

USING AN AIR SOURCE HEAT PUMP FOR HEATING

Heat pumps work best when there’s less of a difference between the inside and outside temperatures. In much the same way that your fridge has to work harder in hot weather.

This makes them a good match for underfloor heating systems. Floors cover a much bigger area than radiators so they don’t need to get as hot to provide the same amount of heat.

Air source heat pumps also have a lower output than a gas or oil-fired boiler. This means they can’t deliver heat as quickly. Instead, they’re best used to heat your home up slowly over a longer period.

AIR SOURCE HEAT PUMP SECRETS AND RADIATORS

If you have radiators in your home, and you’re switching from a gas-fired heating system to an air source heat pump, you’ll probably need to buy some bigger radiators to keep your house toasty.

USING AN AIR SOURCE HEAT PUMP FOR HOT WATER

Heat pumps can also be a great source of hot water – but the water will be cooler than from a boiler. Practically this means that If you’re running a bath, you’ll need more hot water and less from the cold tap. So you’ll likely need a bigger hot water tank to cover your needs too.

REGULATIONS

A fly in the ointment for some is the need to meet regulations when installing an ASHP. Although the vast majority of people don’t need planning permission, there are a couple of things that must be adhered to in order for the ASHP install to be without issue with the local council.

This includes making sure the installation is at least a metre from the boundary of your home, will be used only for heating, is installed on a suitable surface such as the ground or a flat roof (1 metre from the edge), has a maximum volume of .6 cubic metres.

What is Multifoil Insulation? — With Byron Lawson
The benefits of multifoil insulation

Byron Lawson from SuperFOIL explains…

🔗 https://www.superfoil.co.uk

Multifoils explained — FAQ from PBC Today

So how does multifoil insulation work?

It’s not magic but multifoil insulation controls the three mechanisms of heat transfer; radiation, conduction and convection. The low emissivity outer layers reflect up to 95% of infra-red radiation back into the house and prevent the house from emitting infrared radiation to the outside. At the same time, the fibrous insulation core reduces heat loss through conduction and convection.

Multifoil insulation also controls air and vapour movement and as the product is installed across rafters or timber studs it acts as a thermal break and reduces continuous cold bridging.

How is this different to traditional insulation?

Rigid board and fibre insulation are both good at controlling heat loss, but that is all they do.

They don’t control air movement and they don’t control water vapour. By controlling heat, air and vapour movement in one, multifoils address all the needs of the building.

Are multifoils accepted by building control?

LABC has embraced the correct use of multifoil insulation and a number of products, including PhotonAir and PhotonFoil, have been registered within the LABC Registered Detail scheme ensuring their acceptance by building control across England and Wales.

Can multifoil insulation meet new build regulations on its own?

No. There is no multifoil product that will meet current new-build regulations by itself – all will need to be used with additional insulation, for example, PhotonFoil with 65mm PIR will achieve a U-value of 0.18 W/m2.K in a pitched roof.

In refurbishment projects requiring different U-values, there may be situations where multifoil insulation is accepted as an upgrade as a single layer. Here, where the standard is not technically, functionally or economically feasible, the thermal element should be upgraded to the best standards achievable – delivering a simple payback of no greater than 15 years. Generally, this lesser standard should not be worse than 0.7w/m2.k. PhotonAir (an insulating breather membrane) can achieve a U-value of 0.60 in 75mm rafter at 400mm spacing.

It is advisable in these circumstances to consult with your local building control officer.

What goes on the warm side/cold side?

Vapour barrier multifoils, such as PhotonFoil will go on the inside of a roof while breathable products, such as PhotonAir, will go on the outside of a building. In simple terms, it’s about preventing water vapour from getting into the cavity, but, if it does, it needs a mechanism to escape or it runs the risk of developing harmful condensation.

Remember, vapour barrier on the warm side, breathable on the cold side.

Why do I need airgaps and what is optimum?

Airgaps are needed for thermal performance and the optimum is 20mm but it can be less with a small reduction in the R-value.

Do airgaps need to be ventilated to reduce condensation risk?

No, they should be unventilated or the thermal benefit won’t be achieved. All our accepted solutions have condensation risk analysis so they can be used with confidence. Again remember the rule: vapour barrier on the warm side, breathable on the cold side.

If I only have one airgap does this give me a condensation risk?

No, it doesn’t but it will drop the thermal performance. All PhotonFoil and PhotonAir Registered Details have been independently assessed by LABC to ensure they deliver the necessary thermal performance.

What batten sizes do I need?

The Photon range, being 33mm thick, needs a 38mm batten to provide the optimum air gap. Thicker products do however need bigger battens to achieve the optimum air gap, for example, a 40mm thick multifoil typically needs a 50mm batten and 50mm thick multifoil a 70mm batten!

For anything thicker than this then the question is `is it practical or really space-saving?’.

🔗 https://www.worcester-bosch.co.uk/heat-pumps

What are the basic workings of a heat pump?

A heat pump is a relatively new technology in the UK although they are widely used in Scandinavia and many parts of Europe where there is an abundance of renewably sourced electricity.

A heat pump takes energy from outside and transfers it into heat to be circulated around a heating and hot water system.

A heat pump uses electricity to run the components of a heat pump, principally a fan, compressor and circulating pumps to transfer the energy from the heat source into the heat sink or heating system.

Greenstore LECP heat pumps overview

Worcester Bosch Greenstore ground source heat pumps provide economical, low carbon energy, enabling you to meet all of the heating and hot water requirements of your home from one renewable source.

Available in two versions, the system version has been designed for use with a G3 approved Greenstore solar-ready cylinder for the production of hot water, whilst a G3 approved Combination model includes a built-in 185-litre cylinder.

The Crazy Cost of Going Cordless?

The Crazy Cost of Going Cordless?
The next time you are considering buying a new power tool you are very likely to be going cordless..

That is not me reading your mind, it is what all those sales and marketing people have been drip-feeding us in our sleep. It may well be true that a cordless is the best choice but as I am about to explain it might not.

I am old enough to remember when cordless tools first came in. The first 7.2-volt battery drill was nothing more than a gutless toy. It was ok for driving in small screws, but it was certainly no match for this Yankee pump-action screwdriver. The fact that most of you have probably never seen one of these shows just how far cordless tools have come in those years.

Cordless tools were not invented for the moon landing, but this is where they first came to the attention of the world.

You may have seen the pictures of the first man on the Moon using a bloody great hammer drill. No wonder people thought the moon landings were fake. There were a couple of blokes bouncing around in helium-filled suits to make it look like they are in zero gravity and just look at that they haven’t even plugged their drill in.

It was just beyond people’s imagination. Landing on the moon and using a drill that you didn’t need to plug in. The pinnacle of man’s achievements. A lot of people think that the cordless drill was invented for moon landings, but it was around before that. you just couldn’t buy them from Home Depot or B&Q as it is in England.

So Nasa already knew there was such a thing as a battery-powered drill but they needed something special so they contacted Black and Decker to help them develop one that would work on the moon.

Now if you are taking one cordless drill to the moon and you choose a Black and Decker some might call that a brave decision because they were a bit DIY but for Black and Decker it was a result. Their marketing department must have been well…. over the moon ….. but just have a look at that picture of the astronauts using that drill. Try as I might I don’t see the Black and Decker logo on it.

Had these people never watched a James Bond film? Didn’t they understand the concept and value of unsubtle product placement at every opportunity. I mean a few well-placed logos on those pictures that were beamed into every television set on Earth. How much would a deal like that be worth? And why stop there?

Moon Boots by Nike, Space Suit by Pierre Cardin, they could have paid for the whole trip with the advertising revenue and that isn’t including the merch!

But what did the astronauts want a drill for anyway? Bye darling I’m off to the Moon. Have a good trip honey and don’t forget to take your drill.

Well, I can tell you that Neil Armstrong wasn’t going to put up any shelves, which is probably the first act of any colonisation after planting a flag, because he didn’t even take a spirit level. Anyway, the actual drill they took would have been no good for that. It was a core drill for extracting core samples of moon rock so they could take them home and sell ’em on eBay.

Going to the moon? Bring me back a stick of rock. Cut it and it says moon all the way through.
How did they do that?

Actually, while I am talking about NASA’s contribution to cordless technology, even more impressive was the impact wrench that Black and Decker designed with Nasa for the Gemini project. It needed to be able to spin nuts in zero gravity without actually spinning the astronauts around. And that good people is why you can now drive in huge screws one-handed without the impact driver breaking your wrist.

It is all down to kinetics. So, before I get too side-tracked by the wonders of space let’s get back down to Earth.

Houston, we have a problem.

And the problem is that the limitation of cordless tools has always been the battery. They have evolved through NiCad with all its memory issues to Nickel Metal Hydride which is still used on little rechargeable batteries but for other stuff and we have moved onto Li-Ion which gives you more power and a longer run time with less weight, but we are not there yet.
