PIR (polyisocyanurate) Boards

There are also other types of PIR insuation boards, for example, for flat roofs it can have plywood bonded on one side, or glass tissue or plasterboard bonded to it for wall applications. The need to replace the insulation is highly unlikely due to its rigidity, durability and excellent compressive strength. PIR insulation boards require approximately half the thickness of traditional forms of insulation to meet the same level of thermal performance. They achieve low R-values, as low as just 0.021W/mK. It is seen as greatest potential for energy saving today. PIR insulation boards will not rot, sag or decay and will therefore continue to deliver designed insulation values throughout the lifetime of the building.

The insulation core and facings resist attack by mould and microbial growth. They have a fibre free insulation core, and therefore are non-irritant. It is an environment friendly material. Its low weight also lends itself to modern methods of construction and lighter supporting structures. They are easy to handle and transport, making installation much easier and quicker than traditional insulants.

• Foil faced PIR boards
• Cavity PIR boards (partial fill and full fill)
• Mineral coated glass faced or bonded to plywood  PIR boards (flat roof)
• Floor, walls and roof insulation

• Flat and pitched roofs,
• Floors,
• Walls,
• Cavity insulation.

PIR insulation board with core sandwiched between two aluminium foil facings

These insulation boards are available in different thicknesses, 12mm-150mm, all especially designed to eliminate thermal bridges, very easy to cut and shape and energy-efficient. They are used for insulated sheathing on timber frame, insulated sheathing on steel frame, insulation between studs on timber frame wall, external masonry with timber frame or ventilated cladding with timber frame, for pitched and flat roofs and floors. They are unaffected by air infiltration, resistant to the passage of water vapour, easy to handle and install and ideal for new build or refurbishment.

PIR insulation bonded to plasterboard

These insulation boards can be installed relatively quickly, in direct bonding and mechanically fixed installation techniques, can be used for both new construction projects as well as refurbishment projects or upgrading to applicable regulation standards. It is used in solid masonry walls or timber frame lining applications and also as the bottom layer of insulation in between and under rafter and joist applications. Available in 25mm-60mm thicknesses,

PIR insulation bonded to plywood

This type of insulation is used for insulation of timber deck flat roofs, it has high performance rigid thermoset insulation, vapor control layer and decking in one board, with proven reputation as a quality composite roof deck material.

PIR insulation bonded with OSB board

These insulation boards are used as decking and as thermal insulation for new and refurbishment flat roof applications. It is suitable for use in damp environment as it does not readily absorb water. The low thermal conductivity of the insulation minimizes the board thickness. The composite board offers rapid coverage and straightforward installation.

PIR insulation coated with mineral glass

These insulation boards have mineral coated glass facers and are suitable for use below single ply fully adhered roof membranes, single ply waterproofing systems and partially bonded built-up felt. They are suitable for use on roof decks that are subject to maintenance traffic. The product is stable, rot proof and will remain effective for the life span of the building, depending on specification and installation.
