Installation advantage

Apply first. Activate when ready.

Factory or site applied

Bond the protected tape to the frame in a controlled workshop or on the project site.

Applied before the frame

The encapsulated profile supports preparation before the window or door is positioned.

Controlled expansion

The tear-off polypropylene film keeps the foam compressed until activation is required.

600 Pa weather seal

Correctly selected and installed tape provides dependable external weather resistance.

Recessed perimeter sealing

Designed for external recessed joints around window and door frames.

Clean installation

No hazardous waste or wet-sealant clean-up is required after activation.

Controlled sequence

Protected until the moment of activation.

TP601 separates frame preparation from foam expansion, giving installers control over when the seal becomes active.
