The private housing
development of 70 homes
was recently completed in the
countryside town of Hook, by
housebuilder, CALA Homes.
CALA Homes and roofing

together to achieve a high
standard throughout the scheme.
To ensure a sustainable roofing

Sika structural adhesives for façades bring
stability to Senate House roof
Sika’s products have ensured
the long-term durability of a
multifaceted glass roof installed at
The University of London’s Senate
As part of a refurbishment
to create a new academic hub,
the roof was created using 105
completely bespoke glass panels.
Sikasil-SG 500 structural silicone
adhesive and Sikasil WS-605 S
sealant were chosen to bond
multiple glass panels to a steel
frame, allowing for the unusual
shape of the roof design without
the need for mechanical fixing.
Prior to the installation, vital
in-house adhesion testing and

structural calculations were
provided by Sika’s technical
team at Welwyn Garden City to
guarantee the strength of bond
and ensure the project would meet
ETAG 002 European Guidelines.
The roof’s large and unusual
organic design meant bonding
was unable to take place o¤-site.
To counter this, Cantifix – a Sikasil
registered contractor – worked to a
3D-model until on-site where they
individually lifted the glass panels
into the steel frame before bonding
with Sikasil-SG 500.
Klober Permo extreme RS SK2 – the ultimate weatherproof underlay
Permo extreme RS SK2 from Klober is
a waterproof, tear-resistant underlay,
designed for use on low pitched roofs.
Suitable for profile tiles pitched at
12.5o or more, 15o for slates and 22.5o
for plain tiles; it is manufactured
from a bondable two-layered
underlay with a shrink-resistant
TPU coating on a robust PES
(polyethersulphone) fleece, which
allows vapour to escape, while
keeping rain water out.
Double self-adhesive edge strips
provide a permanent seal and
immediate weatherproofing against
wind, rain and snow; while the PES
fleece also incorporates a capillary
stop to control the formation of
condensation. This means that,
unlike traditional vapour permeable
underlays, which provide limited
weather protection if left, Permo
extreme can provide a temporary
weatherproofing layer if required.
With a high-temperature stability
that peaks at 100°C, and due to
the fact that it is UV-resistant, it
also means that Permo extreme is
suitable for installation under in-roof
system solar panels.
Another benefit is that Permo
extreme dispenses with the need for
plywood or OSB support boards and
counter battens, which the company
estimates saves at least £8 per m2 in
materials, not to mention the time
and labour costs.
It’s also said to be the ideal
choice for those seeking a bondable
underlay for a rainproof sub-roof.
Not only is it tear-resistant,
weatherproof and avoids the need
for sarking boards, it also – when
laid as a key primary barrier with its
associated accessories – comes with
a 10-year guarantee, providing that
it has been installed in accordance
with Klober’s installation instructions.
Permo extreme RS SK2 is
complemented by a range of
accessories such as Permo extreme
sealant, which allows connection to
rising structural components and
eave flashings; an EPDM sealing
collar suitable for the sealing of pipe
penetrations; and Butylon tape,
which is ideal for creating seals
around nail penetrations.

Like all of Russell Roof Tiles’
thinner leading-edge range, Bute
is manufactured using 15% less
raw materials than a standard flat
interlocking tile. So that also means
they’re a greener choice and are
delivered to site on fewer pallets,
therefore using less packaging.
