Product Information

Full details

The Celotex GA4080 is a high-performance PIR insulation board designed for builders, contractors, and DIY enthusiasts working on masonry walls, floors, or roof projects. Its primary advantage is the exceptional thermal conductivity of 0.022W/mK, allowing for significant energy savings with a slimmer material profile compared to traditional insulators. While its rigid design offers excellent thermal efficiency, it is important to note that the board requires precise cutting to ensure a snug fit and optimal thermal bridging protection in tight spaces.

FAQs

What is the R-Value of the GA4080 board?

The Celotex GA4080 has an R-Value of 3.60m2K/W.

Can I use these boards on floors?

Yes, these boards are suitable for floor insulation, provided the subfloor is level and structurally sound.

What tools do I need to cut the boards?

A sharp insulation knife or a fine-tooth handsaw is sufficient for cutting the PIR boards.

Are these boards safe to use in roof applications?

Yes, they are highly effective for both pitched and flat roof insulation.

How do I store the boards if I cannot install them immediately?

Store them flat on a dry surface in a ventilated area, protected from the elements and direct sunlight.

Is the foil facing double-sided?

The board features low-emissivity foil facing on both sides to enhance thermal performance.

Troubleshooting

Board is too large for the allocated space

Use a fine-tooth saw to trim the board to the required dimensions, ensuring a friction fit.

Gaps identified between boards after installation

Fill small gaps with appropriate expanding foam or use foil tape to cover joints and maintain thermal continuity.

Surface foil is damaged during installation

Patch the damaged area with high-performance foil tape to maintain the low-emissivity properties.

Pros and Cons

Pros

  • Excellent thermal performance for a slim 80mm thickness
  • Easy to cut and shape with standard hand tools
  • BBA approved for professional construction reliability
  • High thermal resistance (R-Value of 3.60m2K/W)

Cons

  • Requires careful measuring to avoid gaps and thermal bridges
  • Rigid board material can generate dust when cut
  • Large 2400mm x 1200mm dimensions require adequate workspace for handling

Setup, Compatibility & Care

Installation requires standard carpentry tools, such as a fine-tooth saw or a sharp insulation knife. When fitting into masonry walls or steel frames, ensure the structure is dry and clear of debris. To maintain performance, seal all joints with a high-quality foil tape to prevent air infiltration. Store the boards in a cool, dry place off the ground and keep them covered to protect against weathering. While the boards are durable, avoid exposure to prolonged UV light or moisture during the construction phase to preserve the integrity of the foil facing.
