How to cut 150mm insulation?

Cutting depends on the material: Mineral or glass wool: Use a long insulation knife and a straight edge. Rigid boards: Score the panel and snap along the score line. Accuracy is more critical as the thickness increases. Cut mineral or glass wool slightly oversize so the insulation fits snugly without gaps.

How to fix 150mm insulation?

Fixing methods vary: Wool products: Friction-fit between studs or joists. Rigid boards: Use mechanical fixings or adhesive, and keep joints tightly closed. Layered systems: Stagger joints to reduce heat paths. The rule of thumb is: keep it dry, uncompressed, and fully supported. The insulation only performs well if correctly installed.
