Thermal insulation is vital for reducing heating/cooling costs, increasing living quality and avoiding building damage.
INSULATE FOR PROTECTION FROM NOISE
INSULATE FOR PROTECTION AGAINST FIRE
H & B’S material mix and wall systems are fire-proof A1 and produce no toxic fumes.
CONSIDERATION FOR FUTURE GENERATIONS
Efficient insulation reduces the emission of carbon dioxide (CO2) and sulphur dioxide in the atmosphere by more than 50%, which is responsible for the greenhouse effect and acid rains.
To avoid construction errors such as thermal bridges and to achieve the highest possible heat storage capacity, you must carefully observe the working and processing guidelines!
Good interior insulation is vapour permeable and hygroscopic (materials that absorb moisture and can release regulated).
However, it seems logical to assume that the higher the level set by the statutory requirements, the greater the sense of comfort felt by the individual.
Moreover, behaviours and noise nuisance go hand in hand from one country to another.
Generally speaking, a building in which H & B thermal insulation products have been used are not only satisfied all the statutory thermal insulation and acoustic comfort but at the same time improves the fireproof requirements significantly. Without additional costs compared to any of the other solutions in the market!
What is a thermal bridge?
Thermal bridges are junctions where insulation is not continuous and causes heat loss.
A thermal bridge occurs when there is a gap between materials and structural surfaces. The main thermal bridges in a building are found at the junctions of facings and floors, facings and cross walls; facings and roofs, facings and low floors. They also occur each time there is a hole (doors, windows, loggias, etc.). These are structural thermal bridges. These thermal bridges vary in importance according to the type of wall or roof (insulated or not).
A building that is not correctly insulated, thermal bridges represent low comparative losses (usually below 20%) as total losses via the walls and roof are very high (about >1W/m2K).
However, when the walls and roof are very well insulated, the percentage of loss due to thermal bridges becomes high (more than 30%) but general losses are deficient (less than 0.3 W/m2K).
That is why in low energy consuming buildings, it is vital to have very high thermal resistances for walls and roofs to have small heat/cold losses via the junctions.
Integrated thermal bridges
A wall or floor almost always consists of several components pasted, screwed or mechanically assembled together. If they are not well designed, these assembly systems can produce thermal bridges within the system, hence their name of integrated thermal bridges.
How to act on thermal bridges?
At the design level, it is imperative to choose construction processes and components that reduce surface losses as much as possible and integrate the smallest potential losses in the junctions of these surfaces. Whatever insulation systems are used, there are relevant thermal, acoustic and fire safety solutions.
Generally speaking, in the case of individual homes, perfect floor insulation is needed and, depending on the wall insulation, the floor should be covered with a floating floor or a bricked system with built-in insulation.
Thermal bridges increase the building energy demand for heating and cooling. This energy loss can even be higher than, for example, the energy benefit provided by thermal solar collectors for domestic hot water. The public awareness of this fact is, however, shallow.
