Isover Standard 36 (KL36) mineral wool sheets, width 565 mm

Isover Standard 36 are flexible, unfaced mineral wool sheets for insulating walls, ceilings, floors and roofs. The 565 mm wide sheets are intended for timber frames with studs installed at 600 mm centres: the sheets fit snugly between the studs and, thanks to the elasticity of the fibres, stay in place without additional fixings.

Key features

• Thermal conductivity λD 0.036 W/mK (lambda class 36)
• Fire safety class A1 (non-combustible material)
• Highest building product emission class, M1
• Chemically neutral, does not rot or decay, pests do not breed in it; dries quickly if it gets wet
• Sheet size 565×1170 mm, thickness 50–150 mm; 7–20 compressed sheets per pack

Where to use

For timber-framed walls, ceilings, floors and roofs – in new builds, reconstruction, restoration and repair. For better thermal and sound insulation, it is recommended to lay the sheets in several layers with staggered joints, tightly against the structure and against each other, so that no air gaps or thermal bridges form.
