Ventilated Flexyhome 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.
The purpose of the installation is the improvement of the roof ventillation to avoid vapor forming, which could be caused by the temperature difference.
Used as an entrance for the air to the interior of the roof. With the ventilation we achieve great energy economy and we extend the roof lifespan.
Timber:
Dried: which means that the hydration is at 15-16% (ideal for house construction).
Ecological: which means that the timber does not contain chemical loads and that the Swedish Wood Industry policy aids at the absorption of CO2.
GL24 class: which means that it has great mechanical strength.
Timber:
Swedish: which means that it is very compact.
Pine: which offers greater resistance to humidity.
Dried: which means that the hydration is at 15-16% (ideal for house construction).
Ecological: which means that the timber does not contain chemical loads and that the Swedish Wood Industry policy aids at the absorption of CO2.
C24 class: which means that it has great mechanical strength.
The gypsum board roof is not installed directly on the beams; instead, it is screwed on a galvanized metal frame.
– During the summer, the air becomes warmer by the sun, thus becoming lighter and it escapes through the ridge, resulting in the cooling of the roof materials and the reduction of the heat of the interior.
– During the winter, the air moving keeps the insulating materials dry, preventing the formation of moisture. The ventilation also allows the snow that lies on the roof to melt, preventing the formation of large volumes of ice.
A material very durable against weather conditions. Considered to be inflammable and does not contain organic additions like wood or paper, which are sensitive to moisture and can lead to the decay or swelling of the material.
The roof includes tiles made by natural raw material, with a color that does not deteriorate. They do not absorb moisture and they are durable against ice and extremely low temperatures (-50 C).
Used to provide adequate spacing between the wooden finishing and the main roof structure.
Reflective membrane of multiple layers. Consisting of two exterior aluminium foil layers of high purity (99,9%) that reflect 97% of the heat transferred through irradiation. These two layera cover a powerful Air Bubble Film layer, adding mechanical strength and improved resistance to the conducted heat.
It offers a waterproofing layer to the roof, further enhancing resistance to water.
OSB of 11.1 mm, Canadian, made by the LP factory, category 3 – waterproof – with great mechanical properties. This material further enforces the construction.
Certified material (certification No13163) with high thermo-insulation properties. It is self-extinguishing and water proof. Acts as a vapor barrier. Furthermore it has sound proofing properties.
The natural mineral wool offers exceptional thermo-insulation, sound insulation and resistance to fire (A1 category – inflammable material). Knauf Insulation mineral wool with ECOSE Technology contain a formaldehyde-free conjoiner, which is produced by rapidly renewable organic materials and does not contain petrol-based chemicals.
Polymeric shingles are a “technical evolution” of shingles, developed to offer the higher resistance to UV rays, that means to increase the life of the roof. They are produced with polymeric bitumen modified with polyolefins, to ensure a better workability of the shingles with cold temperature and a better adherence of the ceramic granules.
Certified gypsum board (certification No520:2004+A1:2009) of Knauf company, 12.5 mm thick, complying with the german DIN 18180. With natural gypsum and biological control certifications.
