Application

The ROCKWOOL® Soffit Slab is a mineral wool fire-resistant insulation that also offers important acoustic and thermal benefits for concrete soffits.

Description

The Soffit Slab has been created to provide a cost-effective fire resistant and thermal insulation solution for structural elements such as concrete car park soffits. The Soffit Slab is manufactured from non-combustible rigid ROCKWOOL® board and has been designed with a variety of facings. To suit requirements of design schemes, it is available with a black or white tissue facing, aluminium foil facing, un-faced and also with a non-combustible high impact board. The rigid ROCKWOOL insulation board also offers excellent thermal and acoustic performance - available in various thicknesses, it provides up to four hours protection, for concrete soffits. The ROCKWOOL® Soffit Slab is water repellent and breathable.


Features and benefits:

  • Non-combustible stone wool insulation with a choice of facing options.
  • Up to four hours fire resistance.
  • Easily cut to accommodate services.
  • Simply butt together at joints.
  • Hi-impact option for durability.
  • CE marked in accordance with BS EN 13162.


Fire performance:

ROCKWOOL® Soffit Slab achieves a reaction to fire classification of A1 as defined in BS EN 13501-1. Soffit Slabs have been tested to BS 476:Part 21 to offer fire protection to reinforced concrete floors.


Thermal performance:

Thermal resistance of un-faced Soffit Slab:

  • 130 mm Soffit Slab: 3.82 m²K/W.
  • 145 mm Soffit Slab: 4.26 m²K/W.
  • 160 mm Soffit Slab: 4.70 m²K/W.

A typical construction comprising of a 150 mm concrete floor slab underlined with 130 mm thick Soffit Slab would achieve a U-value of 0.25 W/m²K. A U-value of 0.20 W/m²K can be achieved using 160 mm thick Soffit Slab.
