K 253: framed fire protection cladding of steel structures with KNAUF-Fireboard boards
Framed cladding of steel structures with KNAUF-Fireboard boards: fire protection performance groups 1–7, up to R 240.

KNAUF-Fireboard is the core material of KNAUF fire protection systems: these boards are used to build K 253 steel structure cladding, cable enclosures and air duct cladding. The gypsum core with vermiculite is reinforced with glass roving and faced with non-combustible glass fibre mat; to GOST 30244 the material is non-combustible (NG). The boards are installed on a framework of KNAUF profiles or without a framework, and joints are filled with KNAUF-Unihard or Fugen compounds; the field of application is premises with dry and normal humidity. Made in Russia; formats 2,500×1,200 and 2,000×1,200 mm.
