- Finnfoam thermal insulation materials hold the Finnish Building Information Foundation M1_-_Rakennusmateriaalien_päästöluokitus.pdf )
- Finnfoam releases no gases or particles that are harmful to health.
- Finnfoam does not decay or rot (studied by VTT Technical Research Centre of Finland).
- Finnfoam's chemical durability is good. Finnfoam resists water and inorganic chemicals such as acids and alkaloids. It cannot, however, withstand organic chemicals or other hydrocarbon solvents.
- Finnfoam does not form a source of nutrition for micro-organisms, and organisms do not build up inside it.
- Using Finnfoam saves costs in other construction materials as no crosswise studwork, wind protection sheets or vapour barriers are required.
- Finnfoam's insulation capacity is excellent even with light structures, leaving more square metres for actual use.
- Finnfoam is easy to handle. It can be worked using regular woodworking tools.
- Finnfoam does not crumble, sting or produce dust. In short, it is pleasant to use.
- Finnfoam can be glued using different types of polyurethane and epoxy glues and construction adhesives (always follow the manufacturer's instructions).
- Finnfoam can be painted or coated using latex-based paints and urethane and epoxy resins.
- Finnfoam can be used with all regular construction materials.
Fire properties and usage temperatures
Finnfoam's fire rating is F. It does not contain toxic fire retardants based on bromine compounds. The required level of fire protection must always be achieved using structural solutions. Finnfoam does not permit the flow of air (oxygen) to a fire. Finnfoam does not burn well. In closed spaces, Finnfoam fires tend to suffocate. Finnfoam's ignition temperature is over 300 degrees, and its auto-ignition point is over 400 degrees.
Its emissions and burning by-products are very similar to those of wood. Finnfoam's long-term usage temperature range (in other words, the temperature range within which the board's strength characteristics remain virtually unchanged) is approximately -180 to +75°C. The boards maintain their shape at temperatures of up to about +90°C.
Finnfoam's thermal expansion coefficient 0.07 mm/(mK), and its density is 30 to 50 kg/m3.
