Roxboard Fire Sealant System

A complete system for fire-sealing openings and lead-throughs in concrete, brick or plaster walls. Is also suitable for concete and lightweight concrete floor structures. The system is approved by Swedcert in fire resistance class EI 60 and El 120, depending upon the type of opening (certificate no 0504) or type of lead-through (cert. no. 0503). Detailed instructions are to found in the relevant approval document.

Product description.

The system consist of Roxboard mineral wool (covered on one or both sides with water-based paint FireFront Coating FFC) and Båk Fire-Sealant (FireFront Sealant FFS) with accessories. The assembly is simple using a jig-saw and sealing-gun. No finishing work is required, eg. painting. Existing work is easy to change or complement.

Measurement. Roxboard (delivery size) 1200x600x80 mm and 1200x600x60


Båk Fire-Sealant FFS

Fire protective elastic sealant, impervious to smoke and gas. Intended for sealing partition walls, ventilation channels, emergency stairways, lift-shafts and lead-throughs.

Approved in fire resistance class El 60 for cable-openings in walls and floors of lightweight concrete, concrete and brick (cert. no. 0503, appendix 1). The sealant is free from silicon, is water-based, pick resistant and can be painted. The sealant is packaged in 0.3 litre cartridges.


Båk Perfect Foam

Single-component, semi- hard polyuretahne (PU) foam, designed for use in filling joints and cracks in constructions where cold or acoustic insulation are required. May even be used in assembly of window and door frames.


Product description

Båk Perfect Foam is applied with the Perfect Pistol. Precision adjustment allows optimum dosage and reduces foam loss. The foam strings can be regulated from 2 mm upwards by adjusting the dosage screw. No loss from dribbling occurs after use. Setting time is short, cutting being possible after approx. 40 minutes at normal room temperature. Post-application expansion for Perfect Foam is approx. 15- 25%, give minimal foam loss.

Perfect Foam expands without pressure and gives approx. 50 litres per bottle. Setting occurs through contact with air or with the surrounding material's dampness.
