Product Description

Intulac Ultra Top Coat is part of a high performance fire protection coating system for interior wood surfaces. Available in a Matt or Satin finish.

Fire retardant coatings are not designed to upgrade doors to fire doors, fire retardant coatings will provide Class “O” spread of flame but will NOT provide any minutes protection.

Bollom Intulac Ultra Top Coat Matt or Satin has been designed to provide a Class 0 fire rated protective and decorative varnish finish system for interior wood. Bollom Intulac Ultra Top Coat significantly reduces the ignitability of soft and hard woods and other wood derivatives including plywood, chipboard, fibre insulation board, hard board and veneer.

Interlac varnish offers a reduction of ignitability to soft and hard wood and other wood derivatives such as plywood, chipboard, fibre insulation board, hard board, also on veneering that are thicker than 12 mm. Bollom Interlac insulates against heat, checks fire, as well as preventing the propagation of fire and diminishes flue-gas density and flue-gas temperature.
