48K Glass Wool Board 1200x600x50mm Rigid Insulation Slab For Light Steel Structure Wall Thermal Insulation

MYREAL 48K glass wool board is a rigid, dimensionally stable panel formed from resilient glass fibers and a thermosetting resin. At 48 kg/m3 and 50 mm it holds its own shape inside stud cavities, so the insulation layer stays tight against the sheathing and delivers the 0.033 W/(m.K) conductivity across the whole wall area.

Technical Data

Application

Specified for light steel structure walls, curtain wall back-up panels and framed facades where a self-supporting panel is easier to fit than a roll.

• Light steel structure exterior wall thermal insulation
• Curtain wall and cladding back-up insulation
• Stud and frame wall cavity insulation for commercial buildings
• Sandwich panel core replacement and repair insulation
• Fire compartment wall insulation combined with acoustic control

Why This Specification

• 0.033 W/(m.K) thermal conductivity, the lowest in the MYREAL glass wool board range.
• 48 kg/m3 rigid board holds shape vertically, no sagging inside tall wall cavities.
• Class A non-combustible core supports fire compartment wall design.
• NRC 0.95 when installed with a 50 mm rear air gap improves wall acoustics.
• Cut with a standard insulation knife, dust controlled, no special tooling required.
