Installation foam is a polyurethane one -component composition. Immediately after spraying, the foam freezes. As a result of its interaction with air, the foam turns into a solid and porous substance. The mounting foam is used to fill various voids and holes in the concrete surface, laying electrical wiring and various types of sealing seams. This material is usually divided into three types, depending on the temperature range at which they can work: all -season foam - universal; Summer, operating in the temperature range from plus five to thirty -five degrees Celsius, as well as winter, which works from minus eighteen to plus thirty -five.
