Insulating Existing Homes

Homes built before 1980 are unlikely to have any insulation. Insulation can be retrofitted into the ceilings and under floors of most older homes. When insulating an older home you should take into account that the external walls are unlikely ever to be insulated. You should use higher-performing insulation in your ceiling and under floor to compensate.

Insulating an existing home is a good DIY project that can provide a positive return. Installing GreenStuf^® in your ceiling and under floor, and wrapping your hot water cylinder with an EcoWrap is very easy and doesn’t require any specialist skills or tools. Simple to read and follow installation instructions come with each pack.

‘Supplied & Installed’ or ‘Do it yourself’

Retro-fitting GreenStuf^® ceiling and underfloor insulation is a great DIY project. It’s easy and can save you the cost of a tradesman.

If you’re planning to work up in your work space, choose a cooler day as the heat build- up in the roof can be extreme. Installing GreenStuf^® insulation in your ceiling as a DIY project will take about a ½ day to complete. Retrofitting GreenStuf^® Underfloor will take about a day to complete for the average home depending on access and working conditions.

Do it once, Do it right

Effective insulation relies on full coverage and no gaps. Even small gaps will significantly affect the performance of the installed insulation. Don’t compress insulation, as this will also affect the performance and make sure your insulation is installed correctly following the instructions on the Pack. We also recommend you staple a Product Label near access points in your ceiling and underfloor so future home-owners know what has been installed and when.
