Despite what insulation materials you select, a pre-installation suitability inspection or survey is mandatory to evaluate the fittingness. The inspection must focus on identifying defects, dampness in the walls as these problems must be fixed if you want to avoid risks and ensure insulation works well. Measure the width of the wall to make sure that the walls span less than 50mm and so are appropriate for fitting insulation. Also PVC covered electrical cables, if any, found in your home are required to be removed before starting insulation process.

Procedure of Installing Cavity Wall Insulation
The work of retrofitting cavity wall insulation takes around half a day cavity Wall Insulation upon the insulation material being injected to the area due to varying density and method of penetration in to the walls. The good thing about the process is that occupants are not required to vacate the house while the installation process is in the process.

In a typical wall insulation process, small openings are drilled into the mortars at the joint of brick courses of the external wall layer at an interval of one metre space. The insulation material is usually blown into the drilled holes using special insulation equipment. These holes are filled with cavity wall insulation materials.

Subsequently, these holes are filled up in a way that leaves no sign of any such work has been done on the walls. When installation is performed by registered insulation contractors, it receives the 25 years of guarantee from CIGA (Cavity Insulation Guarantee Agency) without renewing or maintenance in the coming years. Thus, one time installation benefits with long time solution and cost savings by reducing load from cooling or heating systems.
