Объяснение:

Insulation is a material that slows or prevents the flow of heat.

Insulation is a key part of any passive designed home, helping to keep heat inside the home in winter and outside the home in summer.

The performance of any insulation product – how well it resists heat flow – is know as its R value. The higher the R value, the higher the level of insulation.
