What To Do When Your Cavity Wall Insulation Fails - Ask The Experts

January 2019

What is Cavity Wall Insulation?

Cavity Wall insulation is a material placed between the two leaves of a cavity wall to inhibit the transfer of heat from a property. For retrofit Cavity Wall Insulation (CWI), a fibrous material, such as glass wool, is blown into the cavity through holes drilled into the masonry, until the space is filled.

In recent times, government schemes such as the Green Deal and Energy Company Obligation (ECO) have given grants to the retrofit cavity wall insulation industry, in an attempt to save homeowners, with poor or no insulation, money on their energy bills.
Why Does it Fail?

The quality of the insulation installed, how it was installed and the suitability of the property itself, are all factors which must be considered when assessing why the retrofit CWI has failed.

Walls that are exposed to poor weather conditions, such as wind-driven rain, are unsuitable for CWI, as a small imperfection in the brick work, or a lack of masonry protection cream on the exterior walls means the insulation is vulnerable to becoming damp, or even sopping wet.

The wet CWI then bridges across the cavity, causing the interior walls to become wet, which will result in damp, condensation and even mould growth within the property.

A quick google search will show numerous properties across the UK that have suffered from the negative effects of poorly or unnecessarily installed CWI.


What Can I Do?

Once CWI is wet, it is almost impossible to dry out. The insulating properties of the materials used mean they are extremely porous, and access to the cavity itself is difficult without embarking on disruptive building works.

Wet CWI can be extracted by removing some bricks to access the material, breaking it down and using a high-pressure vacuum to suck the insulation out of the cavity. However, this process does not rectify the internal damage caused by the bridging of the cavity. Damp walls will need to undergo remediation or the internal environment of the property will not improve.

Internal remediation after CWI failure is, unfortunately, not something which can be avoided. However, the good news is that if done correctly, the internal remediation works could save you money on CWI extraction, as when combined with works on the external masonry, the actual extraction itself becomes unnecessary.


The Wykamol Eco System

To prevent further rain penetration through the exterior wall, pointing should be made good and an application of DrySeal Masonry Protection Cream is essential. With up to 29% energy savings, not only does DrySeal prevent any further dampness coming through the outer leaf of the cavity, but it could save the homeowner almost the same amount of money on their energy bills as promised by CWI companies (up to 33%). This product allows the walls to continue to breath, encouraging the CWI to dry out while preventing any further water ingress.

Interior plaster finishes must be removed, as they will have been contaminated and dampened by the bridging of the cavity. The walls will need to be dried out and an application of Wykamol’s Renovation Plaster applied, which effectively controls the migration of damp and harmful salts. It also has insulating properties which will help improve the energy efficiency lost by the failed CWI.

For particularly saturated masonry however, we may recommend an application of DampStop Mesh Membrane, which can be applied directly on to wet walls, saving time and money.

After finishes have been applied, the system is completed with an application of ThermalDry Anti-Condensation coating, a unique product in the market which utilises micro-technology to prevent condensation and black spot mould from forming on any remaining cold spots on the walls. Where CWI has been poorly installed, gaps can be left uninsulated, causing spots on the interior walls to become significantly colder than the surrounding area, and condensation will occur as a result of this. Walls treated with ThermalDry avoid condensation for up to 60% longer.

Wykamol Knowhow Keeps Dutch MPs Dry

January 2019

Damp and water ingress were causing huge problems. Our laboratory technicians found the cause and recommended the use of HydraDRY and ThermalDRY as a future-proof solution!
The Problem

A prestigious, gated apartment block, close to The Hague in Holland, houses diplomats and other VIPs. Built in the 1950s, it is an iconic building, closely identified with its area.

The problem occurred in the huge tower-like structure, which defines the building, and was suffering from plaster falling off the wall across an area of around 500 m2.

The areas affected were predominantly where the internal concrete lintels were present. Although, at initial inspection stage, this was thought to be severe condensation, further diagnostics showed that the moisture was coming through the external brick-work and through the damaged concrete, as the walls do not have a cavity.

There was evidence of condensation below the bottom windows, which consequently ran down the wall and into the plaster. Evidence of this can clearly be seen from the water marks and the shadow-lines are discernible on the concrete beneath. Under the plaster there was evidence of efflorescence.

The Proposal

We requested samples to be sent back to the UK so that Wykamol's laboratory technicians could undertake testing for water content and salt determination.

After rigorous testing and analysis at our Head Office in Burnley, Lancashire, we proposed that all the plaster be removed and that a coat of HydraDRY applied.

HydraDRY is a BBA and WRAS Approved, cementitious compound designed for application to the internal surfaces of walls and associated solid floors, which could be subject to penetrating dampness.

Next, we advised the addition of Renovation plaster to a depth of 5-7 mm, followed by a finishing plaster.

Finally, a layer of ThermalDRY, an Anti-Condensation Coating which is both thermally insulating and water repelling. It increases the wall temperature, therefore preventing the formation of condensation and mould growth.

Furthermore, some walls had been re-pointed with a very hard mortar, and we suggested using a lime-based grout to replace the hard grout to allow the wall to breathe.
