You will see this on the product description as ‘2 x 570mm / 3 x 380mm’

What does this mean?

Knauf Insulation Loft Roll 44 170mm Combi Cut comes in rolls which are 1140mm wide and features pre-marked perforations. This design enables you to tailor the insulation for:

• 600mm Joist Centres: Tear along the perforation to divide the roll into two sections, each measuring 570mm in width. This size perfectly fits the commonly used 600mm spacing between joists, ensuring a snug and efficient fit.
• 400mm Joist Centres: Alternatively, you can split the roll into three equal parts, each 380mm wide, ideal for smaller 400mm joist centres.

This flexibility ensures that the insulation fits precisely, enhancing its effectiveness by eliminating gaps where heat could potentially escape.

Installation Guide

• First Layer Application: Begin by laying the first 170mm insulation layer between the ceiling joists.
