Cavity Wall Insulation

- Introduction: If your home or building was built after 1920 there is also a gap in the possibility of building the outside of the building There is no cavity (cavity) called a hollow (cavity) between them. I insulated the dark yellow mixture. Cavity wall insulation gives you the opportunity to save heating costs and keep your house warm. Cavity wall insulation (mica fill material) may be a bad conductor, but it allows us to keep the interior of our house warm and cold air allowed to enter the house Not a good insulation material.

Cavity wall insulation material: It has been considered to fill the cavity gap between the inner block and the outer block with an appropriate heat insulating material. However, a separate insulating cavity is likely to be insufficient to achieve the desired U value. Therefore it is also necessary to pay attention to adding internal or external insulation to achieve the target U value. Exterior wall insulation (Rockwool) Injection thermal insulation design has a u value of 0.49 (W / m 2 K). Traditional buildings require ventilation to help the fabric "breathe". Since the chimney greatly contributes to the ventilation rate, in some cases it is advisable to leave the chimney open to allow natural ventilation. However, if the abandoned chimney is completely open, more heat loss tends to occur. If there is no cover, water can enter. Several methods are recommended.

It is necessary to install insulation to reduce the heat lost through the outer wall. Traditionally three general methods have been used, but the most cost-effective way is wall insulation. Alternative methods include facade insulation and internal insulation lining. This is often used when there are no cavities in the wall. In general, all masonry cavity walls manufactured after the 1930s are suitable for insulation installation. Polystyrene beads or mineral fibers with a U value of 0.30 W / m 2 K are blown into the cavity of the wall through the hole. We recommend that you approve approved companies using the system approved by the British Council Board (BBA).
