External Cavity Wall Insulation

wind driven rain areasIn certain areas of the UK it is best advice to insulate a cavity wall from the outside using an exterior insulated render system as opposed to in-filling the cavity.

The map opposite represents the official British Standard Wind Driven Rain Index with the darkest blue sections showing areas in which homes should not be cavity insulated due to wind-driven rain causing damp.

The areas coloured yellow and the lightest blue are suitable for cavity insulation and those coloured purple and deep blue are deemed unsuitable.

The medium blue areas such as Cornwall,Devon and Dorset signify homes that can be safely cavity insulated but only if they are sheltered from driving rain.

 What Are The Risks ?

Originally cavity walls were used in areas at risk of wind driven rain to prevent water penetrating through to the inside by creating an air gap between two walls.

In seeking to cut heat loss and lower heating bills you should not in-fill these cavities as it creates a bridge for water to pass across to the inside and cause damp patches.

Hard To Treat Cavity Walls

Hard To Treat Cavity Walls

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.
