    Finnfoam-FI-K600_210mm_lte.jpgThermal insulation for exterior walls using Finnfoam

    The thermal insulation of walls can be constructed using standard flat-edged or rebated Finnfoam panels, but we also offer products designed specifically for this use. As the Finnfoam wall structure can be built without separate vapor barriers or wind-proofing, the material cost of construction is reduced. In addition, the low number of work elements increases the efficiency of installation.9241_975220f734c00e8908044af39d8fc252.jpg

    Operating principle

    9242_c81bd159ffab4ba4cfcb84109557d3f7.gifThe Finnfoam wall insulation panels are designed for a stud spacing of 600 mm and provide savings in terms of both the number of work elements and space consumed by insulation.

    The panels are easy to install as they require no additional wind-proofing, vapor barriers or backing. Thin construction and cost-effective insulation thickness: 179 mm, U value 0.22–0.24 (insulation 140 mm) and 249 mm, U value 0.15–0.16 (insulation 210 mm). The Finnfoam wall insulation panels have all the great properties of Finnfoam. The vapor barrier is not punctured by nails, it functions both ways, and the panels also provide a sturdy base for gypsum board used as interior cladding, for example.

    All the thermal insulation required for the wall structure as well as the vapor barrier and wind-proofing can be provided with a single work element.

    The structure is also very safe in terms of moisture performance, as the interior cladding follows the relative humidity of indoor air while the framework and exterior cladding follow the relative humidity of outdoor air. In addition, the completely consistent and closed cell structure of Finnfoam prevents the formation of mold.

    9243_76d059b5f794b2415e198b01f055c3f2.gifStructural airtightness is an important part of the energy economy of a building. The airtightness of a building is represented by the air leakage rate, which in a timber-framed building is 4 on average. By improving the leakage rate from 4 to 1, you can save 15% of the entire energy consumption of the building (small house). Studies show that Finnfoam wall insulation is highly leak-proof – even at joints! All seams must be sealed carefully with a flexible PU foam.
