Rockwool Flexi Insulation

Rockwool Flexi Insulation Slab – 50mm (Pack/12 – 1200mmx600mm)

 Rockwool FLEXI®

Rockwool Flexi Insulation® Rockwool Flexi Insulation has been designed as a multi-use, dual-purpose acoustic and thermal mineral wool insulation with a unique flexible edge along one side. The FLEXI slab is manufactured with the patented flexible edge which ensures a perfect fit is maintained between the insulation and the supporting framework.

The insulation can be fitted between fresh timber. And will expand into the wider space as the timber dries out and shrinks back. Other types of insulation can often become displaced resulting in cold spots or poor acoustics. FLEXI provides excellent thermal. and acoustic performance as well as being A1 classified non-combustible for fire resistance.

ROCKWOOL FLEXI® is easy to install and has optimum effectiveness. It is suitable for use all over the home, in pitched roof rafters, framed external walls, internal partitions, intermediate floors, separating walls and floors, and timber suspended ground floors.

Description


ROCKWOOL FLEXI® is a multi-use, thermal, acoustic, and fire insulation product with a unique flexible edge along one side. The patented flexible edge ensures a perfect fit is maintained between the product and its supporting framework for easy installation and optimum effectiveness. FLEXI® is suitable for use between frames in walls, partitions, floors, and roofs, without the need for cutting or waste. Made from renewable volcanic rock, it is extremely fire resistant and significantly reduces the carbon footprint of a building.

Applications



ROCKWOOL FLEXI® is suitable for use in a wide range of applications, including acoustic and fire insulation for partitions, separating walls and floors, as well as thermal insulation for suspended floors, walls, and roofs.

Performance
-Thermal
ROCKWOOL FLEXI is available in a range of thicknesses and widths, with thermal conductivity of 0.038 W/mK, and 0.035 W/mK at 140mm thicknesses and above
-Fire classification
ROCKWOOL FLEXI® achieves a reaction to fire classification of A1, as defined in EN13501-1.
-Thermal applications – timber frame walls
The additional thermal benefits offered by using high-performance (HP) breather membranes (BM) and vapor control layers (VCL) over standard membranes are shown below.
-Effective thermal resistance (R-values) comparisons used for external cavities are as follows:

a. Standard BM =0.18m2K/W: or
b. Tyvek Reflex BM = 0.540m2K/W
c. Protect TF200 Thermo = 0.77m2K/W
Effective thermal resistance (R-values) comparisons used for service void cavities are as follows:

a. Standard VCL =0.18m2K/W: orb. DuPont AirGuard VCL = 0.680m2K/W
c. Protect VC Foil = 0.78m2K/W
