Cavity Wall Insulation and Wall Tie Replacement

The Project

A part stone built house suffering excessive heat loss, high heating bills, wind driven rain penetration and consequent wall-tie corrosion. The owner had been incorrectly advised by a previous insulation surveyor that stone built houses were unsuitable for cavity wall insulation. He had had also been told that it would cost £2800 for wall-tie replacement for only three walls and this work would have had a negative impact on the appearance of his property.

The Solution

Technitherm cavity wall insulation was recommended after a full survey by a trained Technitherm surveyor. Technitherm will insulate the cavities of stone built houses and at the same time provide resistance to wind driven rain penetration and provide structural strength to replace the corroded wall ties. Technitherm is the market leading insulation with a 25 year proven track record.

Outcome

The Homeowner said: “Technitherm has made a real difference to our energy bills. I’ve saved over £300 in the first year and I will save £7500 over the next 25 years. Not only that but the cost of Technitherm was less than the cost of wall-tie replacement and Technitherm has future-proofed my house against wind driven rain penetration. The installation was very fast and was done from the outside with minimum disturbance. Due to the small drill diameter that was used, the external stone appearance has remained the same, our house feels much cosier during the cold winter months and we have noticed a reduction in external noise.
