Gas-tight PIR jointing tape – 50 mm aluminium, 50 m roll

An insulation layer is made up of individual boards, and each joint needs a detail of its own. Tapes and seals finish the junctions between boards, facings and other parts of a wall or roof. They are usually concealed when work is complete, but their contribution to the continuity of the building envelope remains.

For compatible PIR boards, aluminium tape carries the sealing layer across the joint between facings. It does not add thickness to the insulation core. Its role is to connect one board surface to the next where the design requires a continuous seal. This gives the installer a specified detail and helps the envelope meet its intended airtightness.

Gaskets fit the space between adjoining components. The correct material and cross-section can restrict unwanted passage of air or water in that detail. Compare the contact surface, exposure resistance and shape rather than assuming every tape or seal works alike. Suitable EPDM products resist weathering, UV and ozone, which matters on exposed outdoor joints.

Flexible tape can follow changes in the direction of a joint.

A choice of widths lets you match the contact area to the joint.

Self-adhesive types help hold the material in position during installation.

The thin profile can be incorporated without building up the visible finish.

In compatible insulation, cladding and roofing systems, tapes and gaskets connect the individual elements. They can finish facing joints in a loft or match the panel geometry of an industrial building. Restricting leakage at these small areas helps the insulation perform across the entire envelope. Choose a width and cross-section that fits the detail without unnecessarily altering its finish.

SteelProfil can match the tape or seal to the material and joint. Our wider range includes first- and second-grade stock and promotional offers. Compare the dimensions and intended use of the accessories with the insulation or cladding detail.
