Traditional Roof Insulation

Traditional insulation could retain water potentially damaging your home as well as reducing the functionality of the insulation.

Traditional roof insulation.

Thermal and acoustic insulation of flat roofs visitable or not with expanded insulation corkboard. Insulation level are specified by r value. Examples of some of the materials that could be used to improve the weather tightness and insulation of the roof of an old building without jeopardising the traditional breathing performance include vapour permeable roofing felt and sheep s wool insulation. Structural insulated panels sips are prefabricated insulated structural elements for use in building walls ceilings floors and roofs.

The finished structure is readily adaptable. Exceptional load capacities for snow and other conditions that mother nature throws our way. The easiest way to increase the value of your roof assembly is to insulate the insulation with a hybrid roof system. By including a layer of stone wool insulation within your roof system your building will benefit in more ways than one.

Water retention can be a contributor to mold growth. R value is a measure of insulation s ability to resist heat traveling through it. 110 to 120 kg m3 thermal conductivity. Traditional insulation materials may trap moisture and create an environment for mold and potentially rot away your foundation if left unattended.

They provide superior and uniform insulation compared to more traditional construction methods stud or stick frame offering energy savings of 12 to 14. The higher the r value the better the thermal performance of the insulation. Spray foam stays in place and does not settle ensuring total continual performance. λ 0 037 to 0 040 w m c excellent thermal lag excellent soundproofing compression resistance at 10.

In warm climates zones 1 through 4 low density open cell spray foam insulation is the typical choice since it is vapor permeable and will allow drying of the exterior sheathing and roof framing if they happen to get wet via diffusion into the interior of the building. Sip roofs have extreme advantages over traditional framed roofs. This reflects the weatherproofing requirements of older roofing materials like thatch and peg tiles. The table below shows what levels of insulation are cost effective for different climates and locations in the home.

Large spans don t require truss systems. Extreme insulation up to r 51. Traditional or cut roof the traditional option is steeply pitched rarely less than 35. Traditional flat roof solution description.
