Product Description

Envirograf range of halon-free, intumescent acrylic and acoustic mastics are available in standard colours brown, grey, black and white (other colours available on request). Supplied in 310 ml tubes. Prices shown are for white only, other colours price on asking.

For fire stopping gaps from 1mm up to 60mm wide. For wider gaps, fit Passive Fire Products fireproof sponge into the gap first. After application, a skin forms that allows painting, but the material stays permanently flexible and expands up to five times its volume in a fire. Ideal for use horizontally or vertically around exit door frames, cable trays, ducting, and partitions.

Please note prices shown are for white only, other colours priced on request.
