PIR insulation: aluminium joint tape, 50 mm wide × 50 m

A panel or roof sheet can only deliver its specified performance as part of an assembly with suitably detailed joints. Tapes and seals connect separate elements and limit unintended air or water movement at the points defined by the system. Their cost is small compared with the insulation, yet they help avoid leaving gaps in an otherwise carefully specified envelope.

Aluminium tape designed for PIR boards covers the joint and connects adjacent facings. Use it on a wall, roof or other element where the insulation system specifies this detail. Increasing insulation thickness does not correct a poorly sealed joint; continuity of the facing matters as well.

Self-adhesive tape is useful along long, repeated joints. Choose the width for the geometry and the adhesive contact area required. On a large roof or industrial wall, having the right roll ready saves the crew from improvising the same detail over and over.

Gaskets are selected for the shape of the joint and service conditions. The cross-section and resilience determine how the material fits between components. In walls and roofs this can protect the joint without adding unnecessary bulk. For more complex shapes, a compatible sealant or adhesive may be appropriate.

Properly finished joints help a wall or roof retain its intended thermal and protective functions in a house, store or farm building. Correct accessories reduce the risk of having to repair concealed areas later. A relatively small part of the order can protect a much larger area of the envelope.
