Over the last 100 years, most homes have been built using cavity walls. These were introduced to prevent wind driven rainwater from penetrating the outer wall to the inside surfaces of the property.
However, the space created by the cavity wall leads to the loss of heat and has been identified as one of the main causes for energy waste. As a consequence, a lack of effective cavity wall insulation contributes to higher energy bills and a higher carbon footprint for the home.
Since the 1980s, Building Regulations have required all new houses to be built with insulation material inside the cavity wall. However, contractor malpractices and installation problems have led to reports of cavity wall insulation (CWI) causing dampness in the home.
Most problems with CWI installation have occurred in properties built prior to 1980 with cavity spaces filled with a mineral-wool fibre material. This material would be used to ‘retro-fill’ the cavity wall which is a technique of drilling into the outer wall and inserting the insulation material into the empty space.
Manufacturers have stated that mineral-wool fibre is a water proof material but new research from the Building Research Establishment shows that this type of insulation does absorb water and can lead to rainwater penetrating the inner structure of the building and causing dampness.
Furthermore, this material can lose its insulation effectiveness and cause energy bills to actually increase. This financial cost is further compounded when faulty insulation has to be removed and replaced.
There are a number of factors which could make your home is unsuitable for cavity wall insulation; these include:
Nevertheless, cavity wall insulation (installed correctly with the right materials) remains one of the most effective ways of insulating your home and reducing your energy costs – up to an annual saving of £135. It is also effective in reducing condensation problems resulting from your external walls.
The suitability of cavity wall insulation is dependent on the following criteria:
There are two ways in which you can apply for free cavity wall insulation – the ECO fund and the CERO grant. Below, is a detailed explanation of the eligibility requirements for both resources.
DK Hughes are involved with the ECO fund which is a government energy efficiency scheme in Great Britain to help reduce carbon emissions and tackle fuel poverty. As a result, we have funding to provide homeowners and private renters with free cavity wall insulation – dependent of whether they have the following house types:
To be eligible for free CWI you must also be in receipt of the following benefits:
The CERO grant focuses more properties that have solid walls and are harder to heat. This grant is available to homeowners and private renters and also offers some provision for social housing tenants. Some applicants will get free CWI and others will have to contribute something to the cost. To be eligible to apply you must live in one of the following house types:
Grants are higher for larger properties with no gas central heating with a higher number of bedrooms.
Cavity Insulation Guarantee Agency (CIGA) is an independent body that gives 25 year guarantees for cavity wall insulation fitted with registered installers. CIGA was established after government consultation with the aim of providing householders with an independent, uniform and dependable guarantee covering defects in materials and workmanship.
DK Hughes is a registered (CIGA) installer of cavity wall insulation and we will assess the suitability of your property and recommend the right type of insulation for your home.
