Non-combustible tapered insulation for flat roofs. HARDROCK Multi-Fix (DD) Tapered is a BBA-approved insulation board, fabricated to a fall to provide drainage across a roof. -
Stone wool angle fillet for flat roof applications The area between horizontal and vertical interfaces can sometimes be the most challenging part of a flat roof to insulate and seal. HARDROCK® Multi-fix Angle Fillets have been specifically designed to create a smooth transition at 90° abutments, for effective flat roof insulation and waterproofing. -
Consisting of a dense ROCKWOOL insulation slab bonded to a rigid 6mm exterior-grade fibre cement board, this combination of two non-combustible products provides an impact and weather-resistant insulation solution for flat roof upstands and parapet walls. -
With high-rise living and buildings with multiple-occupancy becoming increasingly common, acoustic performance of intermediate and separating floors is key in design criteria and specifications. Acoustic ROCKFLOOR® delivers robust impact sound protection. -
Sound-absorbing trough fillers for perforated steel decks. The underside of an exposed profiled deck is acoustically reflective, which serves to increase reverberant noise in the space below, making for a noisy and echoey acoustic environment. The solution is to install ROCKWOOL Acoustic Infills into the troughs of a perforated deck. This tissue-faced product acts to absorb incident sound, reducing noise build-up, which lowers the reverberation time and creates a quieter acoustic environment. -
Flexible polymeric acoustic barrier for enhanced sound insulation. Complimenting the acoustic performance of HARDROCK(R) Multi-Fix, ROCKWOOL Acoustic Membrane is a high performance, sound deadening polymeric layer used to enhance the performance of an acoustic roof build-up. An ideal acoustic solution for buildings requiring an exceptionally high acoustic performance, such as schools, hospitals, cinemas, airports, arenas and leisure developments. -
ROCKWOOL® Cavity Batts make a great solution for new builds or extensions – from homes to commercial. The non-combustible, fire resistant solution has been developed for the requirements of new build construction and contains water repellent additives. -
Protection against rainy days Cavity insulation is essential to provide weather-tight protection against inclement weather. The potential for damage caused by moisture can compromise insulation performance, so the ROCKWOOL® Full Fill Cavity Batts provide a great, water resistant solution for new build or extension projects. -
The sky’s the limit Buildings, whether residential or commercial, require effective insulation to keep the weather out and importantly, the heat in. The ROCKWOOL High Performance Partial Fill Cavity Slab has been developed to provide effective thermal insulation for both masonry and frame constructions. -
Insulating the loft is one of the most cost effective and efficient ways to improve the energy performance of a home… and reduce utility bills. ROCKWOOL Roll is the ideal loft insulation solution for horizontal loft application. The mineral wool insulation is an all-round high specification option for thermal and acoustic performance, as well as fire resistance. -
Simplicity and convenience rolled into one. While thermal insulation is the primary driver of the insulation, reducing external sound transfer and improving fire protection are increasingly emerging as considerations for homeowners. As an all-round high specification option for thermal, acoustic and fire performance, ROCKWOOL Rollbatt is the ideal insulation solution for all building types.
