- Reduces heat transfer from radiative heat sources
- Reduces heat transfer from conductive sources
- Divides the air space to reduce convection current
This combined reduction in the types of heat transfer allows you to keep your conditioned air where it belongs, regardless of the season or outdoor weather conditions. Installing your insulation correctly is the key to having it work for you instead of against you – a poor installation can result in a loss of 25-30% of your R-value. Combining insulation with other R-value rated products increases what they call your Effective R-value, and can help you increase your heat retention benefits.
How Insulation Works
R-value and Heat Transfer are the two main factors that determine how well insulation works. Your HVAC system must replace the heat gained in the summer and the heat lost in the winter to keep your space comfortable. Heat resistance is created by properly insulating a space, which reduces heat flow and allows your space to maintain a comfortable, even temperature.
