Flat roof thermal insulation

The roof is the area of the building that deteriorates the most over time. Its exposure to cold, wind and rain causes premature aging of the roof. We will now analyze different ways to insulate and improve an already built roof.

By insulating the roof of a house or premises, we avoid the entry of cold and humidity, and at the same time we reduce the energy consumption of the building by reducing the emission of polluting gases into the atmosphere.

A roof is insulated by reducing the so-called “thermal transmittance”, that is, the amount of heat that is exchanged with the outside. Let’s see what methods exist to insulate the roof, commenting on their advantages and disadvantages.

The advantage of this insulation system is that the building gains in thermal inertia, i.e. the warm concrete structure keeps the heat inside the house longer and the temperature will remain stable. And consequently, the heating fuel cost is also significantly lower.

Rehabilitation, Waterproofing and Insulation of Roofs

There are many flat roofs waterproofed with a bituminous membrane with slate self-protection. They are usually roofs resolved by means of a double membrane totally adhered to the existing support. The support is composed of a system of slopes by means of cellular concrete, arlite or in any case a concrete with very little mechanical resistance, since the function of this one is not other one that to facilitate the runoff of the water towards the drains.

The quickest way would be to place a filter tile over the waterproofing system. If we are going to re-waterproof the roof, by placing an element on top, it would not be necessary to use a self-protected membrane, so a bituminous membrane could be placed adhered to the existing slate. To facilitate this fusion process, it is recommended to apply an asphalt primer, after cleaning up the areas where the original sheet was hollowed out from the substrate. In any case, the filtering tile must be installed on a geotextile that protects the waterproofing membrane from possible puncturing.

Thermal Insulation Basics For The Home

There is no point in turning up the heating to the maximum. What we need to do is to insulate better: we must take note of this to improve the energy efficiency of our home. When carrying out renovation work to improve insulation, start with ceilings and roofs, the main places where heat leaks, up to… 30%! Therefore, with the insulation of the roof we will achieve savings of 30% thanks to lower energy consumption. But why is roof insulation a priority?
