Under the roof, other equally important elements prevent further condensation, protect the building from thermal and acoustic problems and offer significant power savings.

100% quality roof substructure 

 

A proper substructure provides:

- Thermal insulation to protect from the cold in winter
- Heat protection to protect from the summer heat 
- Noise protection
- Fire protection
- Breathability
- Air, wind and water tightness to prevent damage due to humidity convection
- An optimal climate within the living wellness environment

The right materials 

Most waterproof membranes are porous and therefore incapable of handling condensation and air vapour transmission optimally.

The membranes we offer block condensation more effectively, because they have been designed according to stricter criteria to meet harsher conditions.

They provide optimum safety for the roof and are highly diffusion-permeable, but with maximum resistance to driving rain, 3D separation layer provides increased acoustic insulation and ventilation and very high thermal stability.

The vapour control membrane serves to control the passage of moisture and prevent condensation in the interior layers of the roofing structure. In winter, warm air inside the building creates a degree of moisture saturation superior to that of the cold air outside. Therefore, as the internal air cools, we have to reduce the amount of moisture that liquidifies, creating condensation, which causes damage to the structure and creates the ideal conditions for mould to grow.

Given the difference in interior and exterior temperatures, condensation is inevitable. Therefore, it is necessary to try and limit the quantity of water that can form in the structure with a vapour control membrane so that as the warm internal air cools it contains the same amount of moisture as the cool exterior air. 

There are various kinds of insulation, ranging from synthetic (polyester, polystyrene, polyurethane and expansive polyurethane), mineral (glass and rock wool, clay and expansive pearlite, felts), and plant-based (wood, cellulose, hemp and linen fibre, cork).

The insulating capability of the thermal insulating materials is directly linked to the thermal conductivity value. Therefore, in order to insulate the house well, it is important to use materials with low thermal conductivity.

Factors to be taken into consideration include the thickness of the material, thermal lag (time required for the heat to pass through a material and penetrate the house), breathability (the resistance to diffusion of water vapour), and thermal conductivity. The lower the thermal conductivity, the  more breathable the material is and therefore better able to prevent condensation.
