Ventilated Flexyhome roof

Ventilated Roof

3D presentation of the construction materials of the FlexyHome ventilated roof

The Flexyhome roof offers superb insulation to your house, blocking heat or cold from altering your interior temperature.

The insulation is a heat insulating material of high thermal resistance, made of expanded polystyrene with added graphite, at a thickness of 150mm. Combined with the Swedish pine beams (14,5cm thickness) and the OSB sheathing from Canada’s LP factory, we have a very robust result. For the water insulation, asphaltic sheets are installed with asphaltic shingles on top of them.

Ventilated roof: Polymeric tiles, which are a “technical development” of asphalt tile, developed to offer the highest resistance to UV rays, which means an increase in the life of the roof. They are produced with polymer asphalt modified with polyolefins, to ensure better processing of the tiles with cold temperature and better adhesion of the ceramic granules.

It consists of a foil that is subjected to a special treatment, to offer a solid, durable and light finish.

Used for the passage of air inside the roof. Ventilation achieves excellent energy savings and extends the life of the roof.

Highly weather resistant material. It is considered non-combustible and does not contain organic impurities such as wood or paper that are sensitive to moisture conditions and can cause the material to rot or swell.

Ventilation spacers

Used to provide sufficient distance between the wood finish and the roof construction

  • 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 roofing materials and the reduction of the indoor temperature.
  • In winter conditions, the circulating air keeps the insulating material dry, preventing the condensation of moisture. Ventilation also allows the snow that has accumulated on the roof to melt and prevents the formation of ice.

Timber:

  • Dryer: which means that it has a humidity of 15-16% (ideal for house construction) and does NOT have 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 that it has very high mechanical strength.
