Description

ISOVER Spacesaver is a glass mineral wool roll supplied in 100–200 mm thicknesses. The economical and easy-to-fit rolls are pre-perforated to 3 x 386 mm and 2 x 580 mm widths to fit between common joist spacing.

Suitable for loft applications in both new-build and renovation projects, the longer roll lengths help to increase speed of installation and ensure more efficient deliveries and storage. Rolls are installed in at least two layers, the first layer between the joists and the subsequent layer(s) cross laid over the joists. ISOVER Spacesaver can also be installed between the joists in suspended timber ground floors and flat roofs.

Features and benefits:

Pre-perforated to 3 x 386 mm and 2 x 580 mm widths.
