Product Information

Full details

The Unilin XT PR Rigid PIR Insulation Board is designed for builders and renovators seeking superior thermal performance in residential and commercial projects. Its key benefit is achieving excellent U-values with minimal space intrusion due to its ultra-low thermal conductivity. A potential caveat is its specific application requirements for certain roof constructions. This lightweight, foil-faced board offers a reliable solution for floors, walls, and roofs, optimizing thermal bridging and compatible with various construction methods.

Extended Product Information

FAQs

What is the thermal conductivity of the Unilin XT PR board?

The thermal conductivity is an exceptional 0.022W/mK, indicating very low heat transfer.

Can this board be used for warm roof construction?

Yes, it is specifically suitable for warm roof construction, helping to insulate roof timbers and reduce condensation risk.

What are the dimensions of one board?

Each board measures 2400mm x 1200mm x 25mm.

What is the coverage area per board?

The coverage area is 2.88m² per board.

What certifications does this product hold?

It is manufactured under ISO9001 quality standards and certified to EN13166.

Is the board suitable for floors?

Yes, it is ideal for use in floors, providing thermal insulation.

How does the foil facing improve performance?

The foil facing provides a low emissivity surface, which enhances the overall thermal performance by reducing radiant heat transfer.

Troubleshooting

Difficulty cutting boards cleanly

Use a sharp, fine-toothed saw or a specialized insulation knife. Score the face side first, then cut through the board.

Thermal bridging at board edges

Ensure boards are tightly butted together. Use appropriate tapes or sealants recommended for PIR insulation to seal joints effectively.

Board warping or sagging

Ensure boards are stored flat and protected from moisture and extreme temperatures. Verify that the substrate is stable and fixings are appropriate and adequately spaced.

Reduced thermal performance

Check for air gaps, inadequate sealing of joints, or moisture ingress, all of which can compromise thermal performance. Ensure correct installation methods are followed.

Pros and Cons

Pros

Exceptional thermal conductivity (0.022W/mK) for superior insulation.
Versatile for floors, walls, and multiple roof types.
Reduces thermal stress and condensation in warm roof constructions.
Lightweight and easy to handle and install.
Meets stringent quality and performance certifications (ISO9001, EN13166).

Cons

Specific requirements for warm roof constructions may necessitate careful planning.
As a rigid board, cutting and shaping may require specific tools.
25mm thickness might not be sufficient for all high-performance thermal requirements without additional layers.
Coverage is calculated per board, requiring careful estimation for large projects.

Setup, Compatibility & Care

Setup and Installation:

The Unilin XT PR board is designed for straightforward installation. Ensure the substrate is clean, dry, and stable before application. The boards can be cut to size using a fine-toothed saw or insulation knife. Adhere to manufacturer guidelines for fixing methods (e.g., mechanical fixings, adhesives) relevant to the specific application (floor, wall, or roof).

Compatibility:

Roof Constructions: Suitable for ventilated, hybrid, and warm roof constructions. For warm roof applications, ensure continuous insulation coverage over the roof timbers.
Wall Systems: Can be integrated into various wall build-ups, including those requiring high thermal resistance.
Floor Systems: Compatible with most subfloor constructions, providing an effective thermal break.

Care:

Store boards flat in a dry environment, protected from direct sunlight and moisture. Avoid excessive weight or impact that could damage the boards. Keep edges clean and undamaged to ensure a good seal during installation. Once installed, the insulation requires no specific ongoing maintenance beyond standard building upkeep.
