Insulation Removal / Replacement Case Studies

Titan Insulation undertake both the removal and replacement of defective cavity wall insulation across the breadth of England for private tenants, landlords and social housing projects. There are a variety of reasons that cavity wall insulation needs replacing from poor initial installation issues through to damp problems: The case studies below show examples of some of the insulation removal and replacement we have undertaken:

Case Study - Degrading foam insulation ( Urea-formaldehyde )

Problem: Customer has condensation on walls and the property is hard to keep warm

Cause: Most of the properties that have problems have had the Insulation installed 20+ years ago. As the foam ages it degrades starting to cause voids and eventually turns to dust. The degradation of the foam can vary around the property and is generally worse on the weathered side.

Solution: Extraction of the foam externally. The foam needs to be broken down in the wall and then extracted, this can be time consuming as some parts of the wall be far worse than others. Install EcoBead improving the thermal efficiency and removing the cold spots.



Case Study - Incorrect property type for cavity wall. Steel frame detached house, Morten

Incorrect property for cavity wall insulation

Problem: Property had been put on the market for sale but the buyers surveyor had identified that cavity wall had been installed and did not meet building regs. Had advised purchaser not to proceed until insulation was removed.

Cause: Incorrectly installed, construction of building should have been identified on survey.

Solution: Removal externally of bead insulation replacing any bricks were necessary limiting the visual impact of the work done.



Case Study - Incorrect property type for cavity wall. Timber frame detached house, Basingstoke

Problem: Property had been put on the market for sale but the buyers surveyor had identified that cavity wall had been installed and did not meet building regs. Had advised purchaser not to proceed until insulation was removed.

Cause: Incorrectly installed, construction of building should have been identified on survey.

Solution: Removal externally of Yellow wool insulation replacing any bricks were necessary limiting the visual impact of the work done.



Case study - Flood damage - wet wool insulation, Christchurch

Flood daamaged insulation removal. Titan Insulation

Problem: Property was vacant and cold water tank burst causing major damage and soaked the cavity wall fill.

Solution: Extract mineral wool externally using existing drill pattern. Allow property to dry out and install EcoBead cavity wall insulation.



Case Study - Fire damage to beaded property, Bournemouth

Problem: Property had a chimney fire causing damage to internals of property.

Solution: Extract externally the whole house. Although only the chimney area had been only effected it is not possible to re pump bead so the whole house was installed with EcoBead.



Case Study - Loose bead insulation. Detached house, Hurtspierpoint

Cavity wall extraction of loose bead insulation

Problem: Beads were continually filling of the underneath of the kitchen cupboards and blowing round the outside of the property.

Cause: When the bead was installed it as not bonded correctly allowing the bead to either fall out by gravity or be sucked out by wind.

Solution: Extract the bead externally from the property with the minimal visual impact. Replace with EcoBead increasing the thermal efficiency, due to the new installed bead being bonded the problem will cease.



Case study - Wet mineral wool. Semi-detached house, Bolton

Defective cavity wall insulation removal, Titan Insulation

Problem: Damp patches on internal walls causing problems redecorating and unpleasant living.

Cause: Although the mineral wool had been installed correctly and there were no problems with the outer wall. The bricks used in the construction of the house were porous allowing moisture transfer to the wool.

Solution: Removal of the installed wool externally and not refilling due property’s unsuitability for cavity wall insulation.



Case study - Voids/ Light fill in 2 Properties, Sunderland

Cavity wall extraction and removal from Titan Insulation

Problem: Properties were very expensive to run. They were running up large heating bills and would not retain heat.

Cause: Yellow wool insulation had been installed from new internally but had not been blown correctly.

Solution: Removal of the installed Yellow Wool insulation externally. Due to the houses' age and having the original fill installed internally there were no external drill holes. Due to the need to fill the property externally Titan Insulation changed bricks to eliminate a drill pattern over the property. This is far more time consuming but there it disguises evidence that the work has been carried out.

Case study - Large blocks/ Social housing 'Decent Homes'

Replacing Insulation in Social Housing Blocks

Problem: Block does not meet the decent homes standards and is suffering from damp, condensation or has running costs.

Cause: Blocks of housing suffer all the same problems as individual properties which are badly installed material, porous external walls, degrading foam and any damage from flood or fire

Solution: Titan Insulation can manage the whole project to include survey, access equipment, help with funding if available and liaising with residents.
