Attic Insulation

Attic knee wall insulation helps control heat transfer around finished attic rooms. However, insulation alone is not enough. A properly insulated knee wall needs good insulation, air sealing, and moisture control. The correct approach also depends on where your home’s thermal boundary is located. Some homes use the knee wall as the boundary. Others bring […]

Radiant barrier insulation helps reduce radiant heat entering an attic. It uses a reflective, low-emissivity surface to reflect radiant energy. It works differently from fiberglass, cellulose, and spray foam insulation. A radiant barrier does not simply add conventional thermal resistance. Instead, it targets radiant heat from a hot roof. This makes it especially relevant in […]

Mineral wool attic insulation is a dense, fiber-based insulation material. It slows heat transfer through attic floors, walls, and roof assemblies. It is commonly available as batts and rigid insulation products. Mineral wool is also called rock wool or stone wool in many applications. Its main strengths include strong fire performance, good sound control, durability, […]
