Precise insulation with Rectavit

Practical benefits

Low expansion prevents deformation: Controlled low post-expansion protects window frames and building elements from warping during curing.
Flexible 360-degree application: You easily reach tight and awkward cavities by dispensing foam smoothly in any direction.
High thermal insulation performance: This polyurethane foam bonds strongly to common construction materials for a durable, airtight seal.

In a nutshell

The right choise for

With Rectavit Recta Foam 360° low expansion pu insulation foam, you tackle sealing and installation jobs with complete control. The low post-expansion formulation prevents window and door frames from warping during curing and keeps cutting waste to a minimum. Thanks to the 360° valve system, you can easily spray the 800 ml aerosol can at any angle, making it simple to reach awkward cavities and pipe penetrations. The polyurethane foam bonds firmly to common building materials and cures through moisture absorption. Once fully cured, the foam can be neatly finished with plaster or paint.
