How to install 140mm PIR insulation?

The steps involved in installing 140mm PIR sheets include preparing the work area, taking measurements of both the space that needs to be insulated and the insulation panel, and resizing the board as required. You can then secure the board in position. As Insulation Wholesale emphasises, following the manufacturer’s installation guidelines reduces your chances of making errors that can negatively impact the performance of the insulation panel.

How to cut 140mm PIR insulation?

You’ll need an insulation cutter or a suitable saw to cut through a 140mm PIR board. Good choices include the plunge saw, table saw, or a good old handsaw. You’ll need a fence to guide the saw into producing a dimensionally accurate cut. If using a handsaw, you may need to cut the board in two phases because it may be challenging to keep it plumb when cutting from top to bottom: Make an initial shallow cut, then follow with a deeper cut that cuts through the entire thickness.

How much 140mm PIR insulation do I need?

The best way to determine how many 140mm PIR boards you need is by measuring the space where you will install the insulation. Add a 10-15% allowance to account for any cuts you make. Divide this number by the total coverage of one 140mm PIR board.
