Making homes warmer …

Cavity Extraction

Energystore Ltd are industry specialists when it comes to cavity extraction. We are the first BBA accredited Cavity Clean Specialists in NI and have carried out over extractions in NI and ROI.

 

All cavities are cleared of “old” insulation and debris, inspected and certified as being completely clear.  Only when completely clear can a cavity then be filled with Energystore’s bonded bead.  A Certificate of Clean is issued  and  a CIGA Guarantee is then applied for.

Why should I replace my existing insulation?

Older insulation materials such as:

 

  • Urea Formaldehyde Board
  • Mineral Fibre
  • Glass Fibre

 

tend to break down over time or can get saturated with moisture.
With brick and mortar being of a porous nature, moisture can penetrate into the insulation material. If the insulation gets damp, with little air circulation the damp can become saturated, and the insulation material soon becomes a heat inhibiter rather than an insulator.  This damp  can then penetrate into the inside wall causing darkened damp spots, crumbling plaster or fungal decay.  If not dealt with this could lead to structural damage.

 

Similarly, poorly or incorrectly installed insulation material, may cause voids in the insulation causing cold spots in large areas of outer walls.

 

With advances in technology over the last 40 years, even with the more modern white bead insulation material, the current Graphite Plus has superior insulation properties.  Extracting the old insulation material and replacing this with the most modern material will save ongoing costs and make for a warmer household.

How is the extraction done?

The redundant cavity wall insulation is removed using an industrial vacuum machine. A recognised approved drill pattern, similar to that for cavity filling, is drilled. Using compressed air, the old insulation material is directed towards the vacuum and extracted.

 

The removal of insulation material and possible debris starts at the base of the property, working its way up each wall according to the drill pattern, checking with a borescope that the entire cavity wall is free from insulation and debris.  All waste material is bagged and taken away during the extraction. Once completed, a Certificate of Clean can be issued and the filling process can commence.

 

The cavity wall extraction and fill process can take two days to complete in an average three-bedroom detached property. We are not allowed to top up insulation. All gaps and voids must be fully extracted before installation of our insulation can be carried out.

 

All of our cavity extraction teams are trained to the highest standards, and adhere to BBA Cavity Extraction guidelines.
