Rockwool Flexi Insulation

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

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. Acoustic performance 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.

Performance

-Thermal

ROCKWOOL FLEXI is available in a range of thicknesses and widths, with a 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 vapour 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: or
b. DuPont AirGuard VCL = 0.680m2K/W
c. Protect VC Foil = 0.78m2K/W
