Insulation (Seconds) - Texts Prefered

1. What thickness do you need 2. How many sheets or area (squared metres) you need. See below for how to calculate it. Minimum order €900 Rigid board PIR seconds 2400mm x 1200mm (8 x 4) 1200 x 1200 (4 x 4) 1200x400 (16" x 4') Smaller size is precut to make it easier to get into the attic space and when you cut approx 20mm off to suit rafter spacing you have a straight edge to start with on the next board. In most cases the same coverage is got with less hassle cutting just to straighten the sheet after a bad cut! Thickness usually available: 25, 30, 38, 50, 60, 70, 80, 90, 100, 120, 140 and 150. Please work out the area/quantities and thickness before you call. Minimum order €900 Thanks!
