Home Product News Rockwool insulation reaches new heights

Rockwool insulation has been specified and installed on a landmark project in the centre of Manchester, providing two new tower blocks with a façade system that ticks all the boxes: fire prevention, thermal insulation and an aesthetically pleasing external appearance.

The Cambridge Street development includes two and three bedroom apartments, built to alleviate Manchester’s growing population. Originally a vacant brownfield site, the project will provide 282 residential flats in a highly accessible location within Manchester’s City Centre.

Although the location is one of the development’s biggest selling points, it presented a challenge for the construction teams. As well as abiding to the local surroundings, the contractor required an insulation solution that complied with all building regulations, including a U-value of 0.18 W/m²K, and would withstand external elements to ensure a quick and undisruptive installation phase.  The materials also had to conform or exceed the regulation for limited combustibility defined in section B4 of Approved Document B External Fire Spread.

As a fibre based product, Rainscreen Duo Slab can be amalgamated to slot into very tight spaces, leaving no empty gaps and achieving optimum thermal performance. It features a dual density insulation board that incorporates a robust outer surface and a resilient inner face. By compressing the primary fleece onto the top 50mm of the insulation, the product can be used, unprotected, in conditions of severe climatic exposure, including strong wind and rain, as experienced at high altitudes.
