When it comes to choosing the right insulation, consider this. Insulation products that deliver optimal energy efficiency should possess the following characteristics:
- Air-sealing capability to control energy-robbing air leakage, allowing the furnace and air conditioning equipment to work less hard and more efficiently.
- Consistent performance at the rated R-value through the life of the building. Insulation should not sag/settle or off-gas within your walls over time, creating gaps and voids and losing its R-value.
- Flexibility that lets the insulation expand/contract with your home to ensure that the insulation completely adheres to the walls and eliminates any air gaps in the walls that allow air to pass through.
