The ROCKFLOOR® range comprises of two product families; Thermal ROCKFLOOR® and Acoustic ROCKFLOOR®. Thermal ROCKFLOOR® is a dual density insulation providing thermal performance for ground floors. Acoustic ROCKFLOOR® delivers impact sound protection for intermediate and separating floors.
ROCKWOOL ROCKFLOOR® is designed for use in thermal applications, to meet Building Regulations Part L, in ground floors, and for acoustic applications, to meet Building Regulations Part E, in intermediate and separating floors. This document details the different constructions options available.
Tested to BS EN 13162, ROCKWOOL Thermal ROCKFLOOR® has a thermal conductivity of 0.038 W/mK.
Rated A1 when tested to EN 13501-1 classification using test data from reaction to fire test. ROCKFLOOR® boards can be used in conjunction with ROCKWOOL Flexi to construct a compartment floor, providing 1 hour of fire resistance combined with acoustic isolation.
The density and fibre orientation of ROCKFLOOR® means it is especially effective at absorbing vibration, or impact, based sound. Suitable for use in achieving Part E (Sound) of the Building Regulations in separating floors.
ROCKWOOL ROCKFLOOR® complies with the requirements of BS EN 13162 Thermal Insulation Products for Buildings: Factory made mineral wool (MW) products specification.
Because the U-value for ground floors is dependent upon size, shape, soil type, edge, insulation etc, it is not possible to quote specific values. The following tables show the insulation thickness required to suit floor types based on their P/A ratio.
