Spray applied insulation
The UK has some of the oldest housing in Europe, with approximately 20% of current dwellings built before 1919 – that equates to about 5.8 million homes in the UK that are over 100 years old. And, using data1 to 2017, 17% of the current housing stock has been built since 1990. That means that roughly 23.6 million homes across the country were built over 30 years ago.
Britain has an existing housing stock that is the oldest in Europe. And this means that many properties don’t have any insulation – in fact, only about 50% have cavity or solid wall insulation.
Heat loss in a house happens faster in poorly insulated homes. So with no insulation, the existing stock of houses aren’t as energy efficient as they could, and should, be.
It’s generally considered that about 35% of heat lost is through the walls, and 25% is through the roof. The lack of insulation means that cold, external walls are the chief culprit for heat loss because, without adequate insulation, they don’t keep heat inside the home, which makes it harder to maintain a comfortable temperature and causes energy bills to rise as thermostats are turned up higher and are left on for longer. And with the majority of heating systems being reliant upon fossil fuels, not only do energy bills increase but the impact on the planet is also significant.
A new name is emerging in the nascent spray foam insulation industry. Huntsman Building Solutions, part of the global chemicals giant, Huntsman Corporation, has been formed following the acquisition of three existing spray foam brands – Demilec, Lapolla and market leading UK and Republic of Ireland based system, Icynene.
The merging of these three brands under the Huntsman Building Solutions [HBS] title creates an organisation designed to bring innovative solutions to the market which had principally offered only traditional forms of building insulants such as mineral wool and rigid board-type products.
The British Board of Agrement has awarded BBA Certification to world leading spray foam insulation company, Huntsman Building Solutions, for its H2 Foam Lite E product.
Huntsman Building Solutions [HBS] is currently the only manufacturer of spray foam insulation solutions to carry the prestigious BBA certification, which covers its H2 Foam Lite E product for use in a range of construction application including pitched and flat roofs, suspended floors and external walls.
When Britain began its post war building boom, coal was king and energy was relatively cheap, so little thought was given to heat loss and few buildings were constructed with any meaningful level of insulation.
Seventy years on and the world is very different. With sky-high heating costs and a greater focus on the need to reduce energy consumption, builders, landlords and homeowners all take the insulation of their properties much more seriously.
But before we look at insulation it’s important to understand what’s involved. Insulation in a building is introduced to provide resistance to heat flow. The more heat flow resistance the insulation provides, the lower the likely heating [and cooling] costs. Good levels of insulation not only reduce heating and cooling costs, but also improve comfort.
