Insulation works by reducing heat transfer between the inside and outside of a home, helping to maintain comfortable temperatures and reduce energy consumption. The R-Value measures insulation’s thermal resistance, indicating its effectiveness in preventing heat flow.

How does insulation work?

Insulation acts as a protective barrier for your home, safeguarding it against both the chill of winter and the heat of summer. It serves to slow down the movement of heat, thus reducing the amount of energy needed to maintain comfortable temperatures inside a house.

The efficiency depends on its thermal resistance, often referred to as R-value – the higher this value, the better its insulating properties. By trapping pockets of air or using materials that have low conductivity like fiberglass or foam, insulation effectively delays heat transfer from warm areas to cold areas in your home.

This means in winter it prevents heated indoor air from escaping outside; while during summer it keeps cooled air inside, blocking out excessive outdoor heat.
