Aluminium foil sealing tape, 50 mm × 50 m for PIR boards

A panel joint or the junction between a flashing and its substrate occupies little space but affects the whole envelope. Tape and gaskets carry the sealing layer along edges and around changes of shape. Planning them with the main materials makes it easier to complete these details during installation.

Aluminium tape intended for insulation boards closes the joint between their facings. This matters in systems that rely on airtightness and control of water vapour movement. Select a width that gives the required overlap. The same detail can be repeated across large areas and adapted at corners. The strip adds little thickness beneath the next lining, useful in lofts and renovations with limited space.

A gasket specified for the joint fills the space between neighbouring elements. Its resilience helps it maintain contact under the intended operating conditions. This is useful at flashings and profiled covers where the joint is not flat. A preformed cross-section makes the connection repeatable and helps restrict unwanted air movement or rain penetration at that detail.

Cut the tape to the joint length and follow the planned route. Self-adhesive products fit onto the prepared surface without separate fixings for the strip. This is useful on renovations with varying lengths and existing components. A roll can cover long edges or short lengths at a corner or service penetration where the system specifies that detail.

Limiting unintended air movement at joints helps the thermal insulation work as intended. Individual boards form a protective layer once their surfaces are properly connected. Tapes and seals add little bulk to roof, wall and ceiling details. Choose a product compatible with both sides of the joint and with the function it needs to perform.

SteelProfil offers tapes and seals at competitive prices. Ask about current stock and promotions, including first- and second-grade building materials in the broader range. Select accessories to suit your boards and flashings so the joints are protected across the assembly.
