Insulation and Weatherization

Insulation is considered one component of your home's building envelope, which includes all the structure and material that make a barrier between the interior of your home or small business and the natural elements. Doors and windows, exterior walls, and insulation all work together to keep buildings warm in the winter and cool in the summer. Weatherizing—plugging gaps, stopping air leaks, and insulating—will improve the building's capacity to maintain comfort levels, using less energy and less cost.
