The appropriate treatment of the covers is one of the most important steps to ensure the thermal efficiency of buildings. The process of boltherm insulation goes against heat transfer: – for radiation, which is an essential component of energy transferred through the covers (particularly in summer, when you can get up to 93%); – by conduction and convection, due to the air bubble in the material and the process of assembling, with dual air box (2 cm deep, at least).

About/Plate Slab

thermal insulation on board

Any insulation placed in low tile must always obey the installation instructions so as not to compromise the effectiveness of your application.

1. fixing of retractor upwards

2. Boltherm placement in longitudinal direction

3. coverage Treated


Walls and ceilings

The treatment of thermal bridges can make a difference in the correct insulation of buildings. For your flexibility and dimensions, the Boltherm products guarantee continuity of insulation, skirting all the building elements (beams, pillars, curved walls or irregularities, ...) and fixing the thermal bridges. The maintenance of air boxes (2 cm deep, at least) is an integral part of the Assembly process and the efficiency of Boltherm solutions.
