Full Product Description

Sika MultiSeal BT is engineered for the demanding conditions of exposed roofing and cladding joints—environments where ordinary tapes often fail within months. The reflective aluminium foil facing acts as a powerful UV shield, resisting photodegradation even under Pakistan’s intense summer sun.

Beneath the protective foil, the self-adhesive butyl rubber compound delivers an aggressive initial tack. It is formulated to remain flexible and functional across a wide temperature range, from -40°C to +80°C, ensuring the seal does not become brittle or move over time.

Installation is exceptionally straightforward: simply clean the substrate, peel back the release liner, and press the tape firmly into position. No specialist tools, torches, or heating equipment are required.
