Test

Houses built after 1925, are likely to have external walls made of two skins of brick. There would be a cavity between them. The two walls would be held together with wall ties.

Retrofit Cavity Wall Insulation fills that gap, keeping the warmth in – thus saving energy. It can also help reduce condensation inside the house if this is a problem on your external walls.

Your home will usually be suitable for free cavity wall insulation if:
·         the external walls have an unfilled cavity
·         your cavity is at least 50mm wide
·         the masonry or brickwork of your property is in reasonably good condition

But it is not as simple as that.

As a part of the initial survey we also carry out a Cavity Assessment Survey (CAS). This is a PAS2035 and OFGEM compliant survey, with an Independent Surveillance of the Assessment (ISA) by the IAA (Insulation Assurance Authority) .

CIGA is the underwriter of the 25 year guarantee which comes with every cavity wall insulated.

The suitability of the walls to be insulated will be assessed by way of an extensive survey of the property.
This survey includes drilling a small test hole into the wall of each elevation. A borescope (a type of camera) is inserted into each hole and the cavity is examined.

Photographs of the cavity are taken, along with measurements of the depth of the cavity.

All walls are carefully examined and any remedial work noted , such as cracks, unfilled holes, etc. This remedial work has to be completed before the walls can be insulated.

Gutters and down-pipes are examined for any leaks, blocks, or spillage and proper drainage.
The survey will take about 2 hours, and is free of charge. This survey is a part of the Government Retrofit Assessment.

The report and photographs are then uploaded to the CIGA platform for auditing.

This is a part of the greatly improved quality control measures found within the new free Cavity Wall Insulation in Wales Grant scheme.
