Product Information

Full details

The Unilin Insulation PIR Insulation Board is designed for builders and homeowners seeking superior thermal performance in residential and commercial projects. Its key benefit is significantly reducing heat loss with a low thermal conductivity of 0.022W/mK, achieving efficient U-values with minimal space intrusion. A potential caveat is its specific application suitability, primarily for floors, walls, and roofs, particularly in warm roof constructions.

FAQs

What are the exact dimensions of one board?

Each Unilin XT PR Rigid PIR Insulation Board measures 2400mm in length, 1200mm in width, and 120mm in thickness.

What is the coverage area of a single board?

A single board covers an area of 2.88 square meters (2.4m x 1.2m).

Can this insulation board be used for pitched roofs?

Yes, it is suitable for pitched roofs, particularly in warm roof constructions where it is installed above the roof deck.

Is the foil facing on both sides of the board?

The product description specifies a foil-faced polyisocyanurate (PIR) core, typically meaning it is faced on at least one side, often both, for enhanced thermal performance and as a potential vapour control layer.

What is the thermal conductivity value?

The thermal conductivity is an excellent 0.022W/mK.

How does warm roof construction help with condensation?

In a warm roof, insulation is placed above the roof deck, keeping the roof structure warm. This prevents moisture vapour from the inside of the building from reaching cold surfaces within the structure where it could condense.

Can this board be used for external wall insulation?

Yes, it can be used in external wall insulation systems, contributing significantly to the building's thermal envelope.

What standards does this product meet?

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

Troubleshooting

Difficulty achieving a tight fit between boards

Ensure cuts are square and precise. Use a fine-toothed saw or hot wire cutter for clean edges. If minor gaps persist, consider using appropriate insulation gap filler foam or tape suitable for PIR insulation.

Thermal performance not as expected

Verify that the correct board thickness has been used for the U-value target. Check for thermal bridging around openings or junctions that may not have been adequately detailed. Ensure all joints are sealed and there are no significant air gaps.

Foil facing damaged during installation

Minor damage can often be repaired with appropriate foil tape. For larger areas, consider if the damage compromises the thermal performance or air/vapour barrier requirements. Consult relevant building codes or a professional if unsure.

Condensation observed in roof structure

While designed to mitigate condensation in warm roofs, ensure the ventilation strategy for hybrid or ventilated roofs is correctly implemented. Verify that the vapour control layer (if applicable) is correctly installed on the warm side of the insulation.

Pros and Cons

Pros

Exceptional thermal insulation properties (0.022W/mK).
Suitable for a wide range of building applications (floors, walls, roofs).
Enhances energy efficiency and reduces heating costs.
Simplifies complex roof insulation with warm roof capability.
Lightweight and easy to cut and install.
Guaranteed quality through ISO9001 and EN13166 certifications.

Cons

Primarily suited for specific building elements (floors, walls, roofs).
Requires careful handling to maintain board integrity.
PIR boards may not be suitable for all types of building constructions or regulations without expert consultation.
Foil facing requires specific detailing for vapour control layers in some applications.
The 120mm thickness may not be sufficient for all thermal performance targets without additional insulation layers.

Setup, Compatibility & Care

Setup: The Unilin XT PR Rigid PIR Insulation Board is designed for straightforward installation. It can be cut to size using a fine-toothed saw or a hot wire cutter. Ensure clean, straight cuts for optimal fitting.

Compatibility: This board is compatible with various building systems, including timber frame, masonry, and steel frame construction. It is particularly well-suited for ventilated, hybrid, and warm roof applications. When installing in conjunction with other materials, ensure compatibility with adhesives, fixings, and any required vapour or weather control layers according to building regulations and manufacturer guidelines.

Care: Store boards flat in a dry, weatherproof location, away from direct sunlight and sources of heat. Protect edges from damage. During installation, avoid excessive exposure to moisture. Clean surfaces with a damp cloth if necessary; avoid abrasive cleaners. After installation, ensure the insulation is protected from the elements and construction traffic.
