Casali Stripstick 3mm Self-Adhesive Vented Underlay – 10m Roll

Casali Stripstick is a premium 3mm SBS-modified self-adhesive vented roofing underlay, engineered for high-performance flat roofing systems where fire safety, moisture control, and long-term durability are essential.

Manufactured by leading Italian waterproofing specialists Casali, Stripstick is specifically designed as the ideal base layer within multi-layer roofing specifications for both commercial and residential applications.

Advanced Vented Technology

The unique vented self-adhesive underside features strategically positioned bonding strips which create ventilation channels beneath the membrane. This innovative system allows trapped moisture and water vapour within the roof structure to escape freely, helping to prevent blistering, pressure build-up, and premature membrane failure.

Safe Flame-Free Installation

Casali Stripstick can be cold-applied directly onto heat-sensitive and combustible substrates including:

• Timber tongue-and-groove decking
• OSB boards
• Foil-faced insulation boards
• Timber roof structures

Its self-adhesive application eliminates the need for direct torching onto the deck, significantly improving installation safety on sensitive substrates.

Built-In Torch Protection

Once installed, the robust 3mm SBS-modified membrane acts as a thermal barrier, allowing the subsequent mineral cap sheet to be safely torch-applied without risking damage to the timber deck below.
