ROOFS

The leak-proof and highly insulating FINNFOAM allows  you to easily insulate your attic and save space in the process. The completely consistent cell structure of FINNFOAM means that separate wind-proofing or vapor barriers are not needed in the structure. Due to the strength of FINNFOAM, separate additional studs are not required under the roof trusses, which allows you to create a continuous layer of thermal insulation below the trusses and minimize thermal bridging.

ROOFS

FINNFOAM FI and FL-K600 panels were designed specifically for insulating roofs and attics, and they are available in thicknesses of 210, 250, and 370 mm. FINNFOAM panels are intended for exact stud spacing, as the self-sealing construction of the panels allows for ±10 mm of variance in the spacing of roof trusses. The insulation panel for roofs was designed for an on-center stud spacing of 600 mm (550 mm of free space between joists). With FINNFOAM, you can provide the necessary wind-proofing, thermal insulation, and vapor barrier with a single installation. Further information about the panel can be found in the Walls section.

FINNFOAM is leak-proof and easy-to work with and provides an easy method to insulate an attic while saving space. Insulating with FL-K600 is quick in new construction, and the product is also suitable for renovation sites with appropriate stud spacing.

SEAMS MUST BE SEALED CAREFULLY 

FINNFOAM can be cut into appropriately sized pieces easily, as the material does not crumble or produce dust. The leak-proof construction prevents warm air rising up from escaping the structure. Air cannot flow through the fully consistent and closed cell structure, which means that you should focus your attention on sealing the seams. You can use an elastic polyurethane foam sealant to create a continuous and leak-proof structure, which will also provide the most effective soundproofing.

Elastic PU foam can also be used to glue FINNFOAM pieces together, which allows you to minimize wasted material. The U value of a structure does not take into account its air-tightness. However, a leak-proof structure (leakage rate of 1) will consume 15% less energy than a structure whose airtightness at a more conventional level (leakage rate of 4).

FINNFOAM is leak-proof and easy-to work with and provides an easy method to insulate an attic while saving space. A continuous layer of insulation is constructed below the roof truss from sturdy FINNFOAM – no thermal bridging! 

In old buildings, the first layer of insulation is inserted between the roof trusses and fixed in place with flexible PU foam. A continuous layer of sturdy FINNFOAM insulation is installed below the trusses such that the seams overlap with the previous layer – no thermal bridging!

VENTILATION GAP IS IMPORTANT 

As moisture cannot breach the FINNFOAM panels, they do not require ventilation as such. However, ventilation is required to ensure that the roof trusses remain dry requires, which is why you should always leave a ventilation gap between the roof covering and FINNFOAM (approx. 50 mm).
