FAQs

An R-value measures insulation effectiveness in your home. Higher R-values indicate better insulation quality, providing superior protection against weather and external elements. Choosing products with higher R-values ensures improved insulation for your home.

The required insulation levels vary by county. Washington and Kane counties require R38, while Iron, Beaver, and Garfield counties mandate R49 to meet building codes.

Properly installed insulation typically lasts between 15 to 20 years, depending on the quality of the materials used. Regular inspections can help determine when replacement might be necessary.

The decision to remove or add insulation depends on its current condition. If the existing insulation is wet or damaged, it should be replaced to prevent potential roof damage. For insulation in good condition, adding a new layer is often sufficient. Selby Insulation can evaluate your current insulation and provide expert recommendations on the best course of action.
