Mold, Pests, Allergens: Is the product resistant or prone to these pests? Also, try to go for those that are made from recycled items. In conclusion, it is impossible to adequately compare insulations while only looking at a single number such as the R-value, since the R-value of solid insulations is not comparable to the R-value of fiber insulations, and because R-value only looks at resistance to heat loss without taking into account resistance to air, vapor, and water. Ukvarjamo se preteno z barvanjem in ienjem fasad ,barvanje napuev in vseh drug lesenih ter kovinskih povrin. The only category in which this product scores positive points is Durability.
