What is Cavity Wall Insulation Technique?

In the past, exterior walls were constructed so that there was a 50mm gap between the joining of two walls. The wall with such a gap is taken as a cavity wall. Ancient buildings or homes are seen with cavity walls at the exterior side of the home. With the aim to improve the heating system of old places, an insulated material is filled between the wall cavities. This technique prevents heat loss from external walls and you enjoy a warm environment inside your home.

Is it Appropriate for your house?

The cavity wall insulation technique will suit your place under the following circumstances. For instance:

Exterior walls have cavities
The wall structure is intact and sturdy
The thickness of the cavity wall lies between 30mm-50mm
No cracks in the walls

Which Insulated Material is used?

Cavity walls are insulated by using high-quality and durable material. Various types of insulated substances are available in the market i.e. polystyrene, mineral fiber (graphite, wool, glass), and insulation foam (polyurethane foam) Polystyrene beads are more effective than other materials as they have a high capacity to keep your home warm.

The Procedure of Cavity Wall Insulation

It is important to understand the entire process of implementing cavity wall insulation. The easiest way is to create holes in the cavity walls. It is done with the help of a drilling machine. The diameter of the holes must be appropriate in width (25mm). Then, the insulating substance is inserted into the cavities, and depressions are sealed again by using solid material. Most probably, cement is used to lock the entire structure. Are you interested in this innovative technique? Then, what are you waiting for?
