Insulation board

Insulation works by slowing down the transfer of heat between the inside and outside of your home. The thicker the insulation, the better it can trap heat inside during the winter and keep it out during the summer.

The rightinsulation thicknesswill also help you maintain consistent indoor temperatures while lowering your heating and cooling costs.

Inadequate insulation, on the other hand, can lead to uncomfortable drafts, higher energy bills, and even damage to your home from extreme weather conditions.

That’s why it's essential to understand how thick your insulation should be for optimal performance.

Understanding Insulation R-Value

The effectiveness of insulation is measured by itsR-value– a rating that indicates how well the material resists heat flow.

Minimum insulation thickness for exterior walls

The higher the R-value, the better the insulation. Different parts of your home require different R-values depending on the climate, the materials in your walls, and where the insulation is being installed.

Generally, the thicker the insulation, the higher the R-value.
