Whilst cavity wall insulation is great for cutting heat loss and reducing energy bills it is not automatically recommended for every house with a cavity wall.
With certain construction methods filling the cavity can cause damp,condensation and possible long term structural damage. To help avoid these problems the Government has issued advice to owners of certain property types as outlined below.
The Department for Energy & Climate Change ( DECC) consider the following types of walls to be unsuitable for cavity insulation :
Narrow Cavity—Masonry cavities that are less than 50 mm wide,typically 1930′s homes
Concrete Construction—Prefabricated concrete walls with cavities of whatever width.
Metal Frame Construction- Steel frame systems with any size cavity.
Random Stone — Uneven cavities formed in walls constructed of natural stone outer leaf and block/brick inner leaf.
Timber Frame – Uninsulated studded cavity (also those with a masonry cavity, which must not be filled).
Excess Height - Generally not recommended if more than four storeys tall.
Exposed Location - Homes which are Elevated, Western Coastal or Open to severe wind driven rain.
