“Crown DriTherm
Cavity Slab is one of our most popular products as it is much
more cost effective than rigid foam board solutions in external
cavity wall applications while still attaining equivalent levels of
thermal resistance. Contractors find that the product is quick and
easy to install while the 50 year moisture resistance guarantee
gives peace of mind to the housebuilder and homeowner alike.
Furthermore reliable performance with minimal heat loss is assured
as the slabs knit together at joints preventing heat loss.”

CHALLENGE
With the increasingly difficult challenges posed by the Code for
Sustainable Homes, developers are looking for cost effective
solutions which do not compromise performance and enable them to
meet the various targets required by the different levels of the
Code.
On the Egypt Hill, Leckhampstead project in the South-East of
England the housebuilder was looking for a Code level 3 solution
which would guarantee high levels of energy efficiency and long
term performance as well as an insulation material which was
inherently sustainable.
The scale of the project meant that any products used needed to
be both cost effective and easy to install and would also need to
offer the very highest standards of moisture resistance and thermal
efficiency.
SOLUTION
Knauf Insulation proposed full fill 100mm Crown DriTherm 32
Cavity Slab as a cost effective and sustainable method of
achieving the Code level 3 requirements of the project.
Crown
DriTherm Cavity Slabs are semi-rigid or rigid slabs of
non-combustible glass mineral wool which ensure excellent levels of
thermal efficiency. They are inherently sustainable as they are
manufactured using a high content of recycled glass bottles.
Because there is no requirement for special retaining discs or
cavity barriers, Crown DriTherm Cavity Slabs are both quicker to
install and more cost effective than rigid foam boards.
The entire range is BBA certified for all exposure zones and has
a 35 year successful performance heritage with millions of cavities
already insulated.
The product ensures reliable long term performance with minimal
heat loss due to the fact that the slabs knit together at joints
and fully fill the cavity and thereby problems associated with
partial fill cavities can be avoided.
Crown
DriTherm Cavity Slabs are rigorously tested and are formally
guaranteed for 50 years to prevent the transmission of liquid water
from the outer masonry leaf to the inner masonry leaf.
DriTherm is the only cavity wall insulation product to offer
such an array of benefits while remaining a costeffective and
sustainable option. With solutions for every level of the Code,
DriTherm offers flexibility in designing low and zero carbon homes
not just today but also in the future.
