As many homeowners begin to insulate their homes to make cost and energy savings, developers and housebuilders have a responsibility to make sure their developments have the correct insulation installed

A tool in the fight for zero carbon Neil Marshall discusses just how integral insulation is in the move towards both low and zero carbon developments

With homes producing over a quarter of the UK’s carbon emissions, the onus on reducing their carbon footprint has never been greater for housebuilders. It’s now a priority issue for government too.

fuel used all contribute to its carbon emissions and a worrying fact is that, for over half of all homes in the UK, a significant proportion of the money spent on energy is literally being thrown out of the window as a result of inadequate levels of insulation, with around 50 per cent of the heat being lost through the roof and walls.

inadequate insulation, but also the role housebuilders and developers have in making sure their developments are properly insulated.

SOLID WALL INSULATION The UK’s housing stock is estimated at approximately 24.5 million dwellings and 36 per cent are made up of non-cavity wall construction – solid brick, solid stone, pre-1944 timber frame and non-traditional, i.e. concrete construction. These types of buildings lose more heat and

energy than any other type of construction – a worrying fact when it is estimated that around seven million properties with solid walls have little or no insulation. While many local authorities, housing associations, private landlords and home owners have been concentrating on filling cavities to achieve their carbon savings, it has to be said that improving the thermal efficiency of solid- wall properties has largely been ignored. This is primarily because the solutions are deemed to be more expensive by housebuilders and developers, and they are believed to cause greater disruption, hence the reason that these types of dwellings are referred to as “Hard to treat Homes”.
