INSULATION
KEEPING PACE WITH SUSTAINABLE DEMAND
There’s only so far that keeping abreast of legislation changes can help merchants, who, ideally, need to really understand the issues as BMJ finds out.
P
eople across all trades are increasingly being asked to source more sustainable solutions for residential projects, whether they are working on a new build that must comply with regulations, or retrofitting an existing property. Sourcing and installing the right insulation and ventilation is, therefore, a key component in creating an energy efficient home. That’s according to Chris Pearman, regional sales manager at Jewson, who adds that the changes to Part L of the Building Regulations go some way in directing builders, tradespeople and installers in which products to select. However, keeping pace with new legislation only goes so far.
A drive for change
Pearman says: “Most merchants, tradespeople and customers have an awareness of the importance of insulation and ventilation since changes to Part L of the Building Regulations came into force. It is also an increasingly common request from homeowners who are looking for new ways to make their houses more efficient in light of rising energy costs, particularly those living in the large majority of the UK’s ageing housing stock where there is minimal or no insulation. Indeed, there was a huge spike in sales of insulation last winter, when the cost of energy hit an all-time high.
“At the same time, the reality of climate change is clear to see, with extreme weather on our doorstep, as well as a constant news cycle showing its global impact. This has created a drive for change from all angles, which the industry cannot ignore. Whether you are working on new build properties or retrofitting existing homes, sustainable solutions present a huge opportunity for tradespeople, builders and installers who are looking to lead the way.“ To capitalise on this, Pearman says the first steps should be to consider the products available, and explore whether there are new alternatives that offer better credentials when it comes to sustainability.
“As a bare minimum, all the products used in a project should comply with the new Building
22
Regulations, such as solar PV, ground source and air source heat pumps and insulation. Since the grace period for the changes came to an end earlier this year, we have seen a significant uplift in sales of compliant products in our Making Better Homes range, so we know that positive changes are already being made. In the six months following the changes, we saw a huge 367% rise in sales of innovative insulation, while wastewater heat recovery systems went up by 276% and sustainable timber cladding sales rose by 18%, compared with the same period the previous year.”
The importance of ventilation While insulation is key to keeping a home comfortable, Pearman emphasises that ventilation is vital in achieving good air quality. “In a recent survey we conducted as part of our Making Better Homes Awards scheme, we found that 55% of homeowners have experienced problems in their home relating to poor indoor air quality or ventilation. Out of those who faced issues, the most common included condensation, mould in at least one room, leaks and damaged walls. This can lead to both mental and physical health problems, with nearly one in five (18%) people having to visit a doctor or take medication as a result of their homes, and 16% of people spending time away from their property to try and alleviate their symptoms. Clearly, change is needed.”
As well as tackling the root cause of any issues with damp and considering upgraded windows, doors and natural ventilation, one of the most effective improvements that can be made is the
installation of a mechanical ventilation with heat recovery (MVHR) system. These products are available for a large variety of building sizes and work by supplying and extracting air to and from rooms to improve the air quality. Pearman says they should be a key consideration in any loft conversion project, particularly given the rising challenge of keeping homes cool during the summer months. “Similarly, they are a valuable addition to any new build, helping to cool as well as heat properties in an efficient way. Jewson’s Build Aviator service is just one way in which we encourage the use of these kinds of sustainable solutions across project designs.”
Knowledge is power
He contines: “Merchants play a vital role in not only selling new and innovative products, but in working with their customers to educate them and share knowledge. Many tradespeople are looking to upskill themselves and are in need of training to ensure they have a holistic view of sustainable construction and the role they play. At Jewson, experts provide guidance, training and support at every stage - whether a customer has questions on selecting the right product for the job, or wants to know how best to respond to a brief from their own customer.” While the changing landscape is challenging, Pearman says it has been incredibly positive to see the industry embracing this and looking for the opportunities it presents. “A number of our trade customers are diversifying from their traditional business of extensions and loft conversions to offering energy efficiency projects, sharing knowledge - for the greater good of the industry.” BMJ
