How glass and glazing fits into the Green Homes Grant


Under the Green Homes Grant, double or triple glazing is categorised as a secondary measure. Here we explain what that means for consumers and the sector when it comes to windows, doors and energy efficiency of homes.

How glass and glazing fits into the Green Homes Grant

The Green Homes Grant Scheme will see up to 600,000 homeowners and private landlords receive grants to improve the thermal performance and energy efficiency of their properties. People can apply for vouchers to cover up to two thirds of the cost of installing energy efficient and low-carbon heating improvements in their homes, such as insulation or solar thermal systems.

The improvements have been split into two categories – primary and secondary. Double or triple glazing has been categorised as a secondary measure in the Grant, meaning consumers can only access funding for doors and windows if they first install a primary measure – such as insulation – and funding is only available for those who are wanting to replace single-glazed windows.

Mike Butterick, marketing director, Saint-Gobain Glass, explains: “We should celebrate the fact that the Government is actively supporting energy efficient improvements and that up to £2 billion will be injected into the economy as a result.

“For many retrofit projects, insulation will likely be the primary measure of choice and when external wall insulation is installed, it often makes sense to replace doors and windows – whether they are single or double glazed – at the same time.

“Putting this into context, any double-glazed windows fitted before 2002 when Part L of Building Regulations changed are likely to be ‘G’ rated at best and I’d estimate that there’s around 100 million homes in the UK as such. There’s also likely 20 million homes with doors that were fitted pre-2002 too, which is a great opportunity for businesses in the industry, as well as the homeowners, landlords and tenants who will benefit from these home improvements.”

Working together

As Mike Butterick explains, there is a real opportunity for a partnership approach in the industry. Mike said: “Installers and fabricators should think creatively and collaboratively. Who in their local area has Green Homes Grant installer status they can partner with? And how can they come together with external wall insulators to offer a package to the consumer?”

This collaborative approach is one that Saint-Gobain has adopted wholeheartedly, thinking about how the company’s different brands and businesses can work together to make the most of the scheme and offer a high performing solution for the trade and the homeowner.

For example, high performance doors and windows can make a lot of difference to the performance of buildings in terms of issues such as cold bridging, and the interfaces between frames and wall structures can impact on the effectiveness of insulation.

As the Multi Comfort approach so neatly shows, by thinking of buildings in a wider, holistic context and how different parts of a building fabric interplay, we can create homes that offer exceptional thermal comfort for occupants and we can reduce energy consumption.

Not only should we see the Green Homes Grant as a significant funding boost for the construction industry but it’s also an opportunity for businesses to work better together.
