How to Work with Foam Board Insulation: Cutting, Installing, and Maintenance

Insulated board is a versatile and efficient insulation solution, available in standard 4ft×8ft sheets with thicknesses ranging from 6.35mm (¼ inch) to 50.8mm (2 inches). This guide covers everything you need to know about cutting, installing, and maintaining foam board insulation, ensuring your projects benefit from this effective insulation material.

How to Cut PIR/PUR Foam Board Insulation?

PIR/PUR thermal insulation board is easy to cut to the size that you require, making it a flexible option for various applications. Here is how to achieve a quick and clean cut:

1. Measure and Mark:

Use a tape measure to size up the dimensions you need and mark them out on the foil backing of the foam board.

2. Cutting:

• For thinner thermal insulation boards, use a utility knife to cut along the marked line.
• For thicker boards, a circular saw is more effective.
• For cutting corners and curves, a jigsaw will do the trick

3. Safety:

Always wear safety goggles and use a sturdy workbench to ensure safety and precision.

How to Install PIR Board or PUR Board?

Installing foam board insulation (kingspan insulation) is a straight forward process that can be done with basic tools:

1. Cut to Size:

Once the insulated board is cut to the desired size, it is ready to be installed.

2. Positioning:

• Place the PIR foam insulation board between studs, ensuring each board fits comfortably.
• If the fit is too tight and the foam begins to tear, remove the board and trim it down slightly with a saw.

3. Sealing:

Use a low-expanding spray foam sealant to fill any gaps around the edges, ensuring an airtight seal.
