Knauf Insulation has launched Rocksilk® KrimpactTM Flat Roof Slabs,
a range of high-performance, rock mineral wool slabs specifically
designed for flat roof insulation. A combination of new
technologies has allowed the development of a high strength, rock
mineral wool slab with a uniform density and consistent performance
characteristics. With all-round excellent thermal, acoustic and
fire insulation properties, the three new products further raise
the strength of Knauf Insulation’s already impressive range of roof
insulation products.
The new products come as a direct result of Knauf Insulation’s
multimillion-pound investment at its rock mineral wool production
facility in Queensferry, North Wales. New, state-of-the-art,
fiberising equipment has been installed along with equipment that
utilises KrimpactTM Technology, an advanced manufacturing technique
that aligns the fibres formed during manufacture. The results speak
for themselves!
Rocksilk® KrimpactTM Flat Roof Slabs have a uniform density that
ensures consistent performance characteristics throughout their
thickness. Combined with a high level of impact resistance and
compressive strength, this means there are no ‘weak spots’ to
threaten the integrity of any subsequently applied, waterproof
finishes. (In fact, unlike ‘variable-density’ mineral wool slabs,
Rocksilk® KrimpactTM Flat Roof Slabs can be installed either way
up!).
Rock mineral wool is justifiably well known for its excellent
thermal, acoustic and fire insulation properties. Thermally, Part L
of the Building Regulations specifies an Elemental U-value target
of 0.25W/m2K for flat roofs and this can be achieved using just
one, 140mm thick, layer of Rocksilk® KrimpactTM Flat Roof Slab.
Acoustically, mineral wool is specified by many of the Robust
Details used by designers to comply with Part E of the Building
Regulations in England and Wales due to its outstanding acoustic
insulation properties. And, of course, being a mineral wool it’s
totally non-combustible; a fact recognised by the slabs having a
Euroclass A1 fire classification, the highest rating
possible.
The Rocksilk® KrimpactTM Flat Roof Slab range features three rock
mineral wool: Flat Roof Slab Light, Flat Roof Slab and Flat Roof
Slab Extra. As the names suggest, each varies in strength to allow
the designer to select the most appropriate to meeting the loads
the roof will be expected to withstand.
Introducing the new range, Mark Thompson, Knauf Insulation’s Market
Manager for the non-residential sector, said, “Our investment in
rock mineral wool production means we can manufacture and supply a
technically excellent solution for flat roofs – we’re offering a
high strength mineral wool slab with no ‘small print’! Rocksilk®
KrimpactTM Flat Roofing Slabs have excellent, all-round insulation
properties – thermal, acoustic and fire protection – high
compressive strength and consistent performance. They really do
provide designers with an ideal solution for flat roof insulation –
what else could you possibly want!”
