Ventilated roof

3D presentation of its construction materials FlexyHome ventilated roof

The roof Flexyhome offers excellent insulation in your home, preventing cold or heat from altering the internal temperature.

Insulation is a heat insulating material high thermal resistance, made by expanded polystyrene, in a thickness of 150mm. Combined with Swedish pine beams (14.5cm thick) and OSB reinforcement from Canada's LP factory, we have a very strong effect. For the waterproofing, an asphalt coating is placed with asphalt tiles on them.

Ventilated roof: Polymeric tiles, which are a "technical evolution" of bituminous tiles, developed to offer the highest resistance to UV rays, which means an increase in the life of the roof. They are produced with bitumen polymers modified with polyolefins, to ensure better processing of tiles with cold temperature and better adhesion of ceramic granules.

It is used for the passage of air inside the roof. With ventilation, excellent energy savings are achieved and the lifespan of the roof is extended.

Extremely weather resistant material. It is considered non-combustible and does not contain organic impurities such as wood or paper which are sensitive to moisture conditions and can lead to rotting or swelling of the material.

Ventilation spacers

It is used to provide sufficient clearance between the timber finish and the roof structure

  • In summer conditions the air is heated by the sun, becomes lighter and escapes from the ridge of the roof resulting in the cooling of the roof materials and the reduction of the indoor temperature.
  • In winter conditions, the circulating air keeps the insulating material dry by preventing moisture condensation. The ventilation also allows the snow that has accumulated on the roof to melt and prevents the formation of an ice mass.

Timber:

  • Dryer: meaning it has a moisture content of 15-16% (ideal for house construction) and has NO chemical loads.
  • Ecological: which means that the wood does not contain chemical loads and that the policy of the Swedish Wood Industry contributes to the absorption of carbon dioxide.
  • Class C24: which means it has very high mechanical strength.
