Arrange the attic:

To arrange the attic industrial structure, it is necessary to work on the beams to clear space. The intervention being done through the roof, it brings very little inconvenience for residents.

Such an undertaking requires real professional skills.

A competent company must know how to offer the best solutions for a good quality / price ratio, suitable for every type of roof in accordance with technical specifications studied and validated by a research unit.

Attic layout is done in several steps:
1- After strengthening the existing structure according to specifications and technical studies, we proceed with the creation of an independent floor of the existing trusses to make your attics flexible. This will nullify any transmission of vibrations and ensure soundproofing and the good condition of the ceilings on the ground floor. With this Harnois process, we create an habitable space.

2- Soundproofing between floors through wooden crates prestressed with steel cables and weight distribution through metallic bolt studs embedded in the partitions. With our flexible attics, it’s possible to clear an optimal habitable height, with lowered wooden or metallic floor depending on the situation.
