Product Info.
Product
Rockwool Rockfloor is a tissue faced high compressive strength slab designed to meet both Part E (Acoustic) and new Part L (2006) thermal regulations. The Rockfloor range offers a unique economic dual density thermal insulation for ground floors and acoustic insulation for separating floors. The Rockfloor range offers both rebated and square edge options.
Usage
Rockfloor insulation may be used below most floor constructions, including:
• Flooring grade t & g chipboard, OSB, plywood etc. and supported on concrete slabs (ground bearing and suspended etc), or on fully boarded timber joisted floors.
• Screeds laid in accordance with BS 8204: Part 1, and supported on levelled concrete slabs,plank, beam and block floors etc.
• Concrete ground bearing slabs, on DPM, sand, hardcore.
The unique dual density Rockfloor enables it to be laid over a slightly uneven subfloor with the lower density absorbing imperfections and the high density surface providing excellent point load resitance. Rockfloor can be placed over or under the oversite slab. If placed under the slab an upstand of Rockfloor perimeter edge insulation must be placed around the perimeter to prevent cold bridging.
Advantages
• Excellent acoustic and thermal properties.
• High compressive resistance.
• Easy handling and fitting
• Minimises thermal and acoustic bridging.
Dimensions
Rockfloor boards are manufactured to a standard size of 1000 x 600mm, and in a range of thicknesses from 25 to 130mm. Other thicknesses can be specially made to order, subject to the quantity required.
Finish
Rockwool Rockfloor boards are supplied with a tissue face on the top surface. The surface also provides a useful medium for marking or scribing the boards for cutting, and facilitates the tight laying and jointing of chipboard.
Resistance to moisture
Rockwool Rockfloor is water resistant but requires a DPM to protect against rising damp or high watertable areas.
Compressive strength
Rockfloor will support the loads normally arising in houses, offices, shops and similar areas, due to its high modulus of compression.
Fire Performance
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 flexi to construct a compartment floor, giving 1 hour fire resistance combined with acoustic isolation
