Thermal insulation between brick joints, a solution without aesthetic changes in your home
Usually, the facades of single-family homes, such as a chalet, are built with double brick factory leaf and intermediate chamber. This chamber can be isolated externally with insufflated insulation. The face brick facade is not altered since the holes are made between the joints. We explain this intervention that is very common.
The façade is usually constructed with two sheets of brick, usually half a foot of exposed brick on the outside and double hollow brick on the inside leaving an air chamber between them. The thickness of the chamber varies from 2 cm to 25 cm, depending on the type of construction and the region.
The technique used to isolate a villa with an exposed brick facade is insulation insufflated from the outside, a way of not touching the brick when introducing the insulating material in the air chamber since it is drilled only between the joints of the bricks.
We use injection nozzles between 18 mm and 25 mm, optimal thickness so as not to break the brick when drilling between the brick joints.
It is a result that will not entail aesthetic changes in the chalet and that is carried out very rapidly, without being a nuisance of works or scaffolding or other inconveniences.
The holes that allow the insufflation from the outside are sealed with grout, copying the tonality of the old joint mortar, which does not rise or adjust the outside or inside the entrance of the house.
Although the blowing is done from the outside, it is suggested that the installer can access the interior of the house, either to seal blind boxes or to check the continuity of the interior wall
The insufflation consists of filling of insulating material with any type of existing cavity in a house, being its usual use more widespread in air chambers of facades and false ceilings.
The materials used in the insufflation are:
- Rock wool
- Mineral wool
- Pearls Polystyrene with graphite (EPS)
- Granulated cork
In the case of mineral wool (glass wool or rock wool), it is a thermal, acoustic and fire protection material that comes from the fusion and bundling of sand or rocks.
It can be blown in most single-family and multi-family houses built after 1950 with an air chamber
The insufflated insulation made with mineral wool, for example, provides a series of clear advantages:
- The decrease in the energy bill for heating or air conditioning,
- A warmer or cooler chalet or home
- Reduction of the effect of climate change.
- It will avoid the cold wall effect, the cold rooms will heat up more quickly and the risk of condensation formation will be reduced, alleviating the symptoms of people with allergies.
- Allows to install a smaller and more economical boiler
- Provides more value to the house in case of sale or rent by reducing the price of heating and air conditioning
- It improves the acoustic insulation and, being an incombustible product, provides security in case of fire.
- The beginning of work is immediate; it is a clean, fast and economical installation.
