three of his installation teams.
The Truro based company has
14 years’ experience installing
double glazing. “We’re using
TruFit to differentiate us from our

“Customers are very happy
with TruFit. It gives a consistent

“It’s a very easy system to
work with and the fitters have
taken to it very well. TruFit
makes good business sense and

Hard Graft
Paying Off
P
olyseam has manufactured
sealants and fillers for almost
20 years – for other people.
It is fair to say that if you use
anybody's silicone, it was
probably manufactured in Polyseam's Huddersfield factory. But
18 months ago the company
changed hands and the new
owner saw a different way forward. The Installer talked to UK
sales director Steve Price about
the launch of the company's own
brand – Graft.
Polyseam has no mean track
record...there's the 20 years of
manufacturing experience, 150
products, 8.5 million packs filled
every year exported to 21 countries with a 97.8%+ rating for
delivery and service and with a
fistful of awards to prove it. “The
problem is,” says Steve Price,
“no one at the user end knows
who we are.”
Taking the Graft product range
to market has not proved easy
according to Price. “It takes a
long time to convince the big
chains,” he says. “And the independents mostly belong to buying groups so the problem is the
same. We are trying to dislodge
existing brands. The irony is that
we probably made the stuff in
their tubes anyway.”
The Graft range breaks down
into five categories – an inert
polymer technology sealant;
sealants (silicone, acrylic and
polymer); adhesives and fillers;
dry lining products and passive
fire protection products.
With the Graft range, Polyseam's strategy is to offer a simple range of products with colour
coded packaging to easily identify function. Yellow indicates in-
terior sealants, orange exterior.
Fire rated products are coded
red and so forth. Application is
identified by a series of icons
printed on each pack. If in doubt
you can log onto the Graft website and check the product finder
section. “The products are all
high quality and multi function,”
says Price. “Between them they
cover around 150 applications.
In reality we could have
launched just two types which
covered every application but
the market likes to see a whole
range on offer.”
Price
seems
particularly
pleased with the reformulated IPT
sealant. “This is the first new
sealant technology since polymers were invented,” he says.
“And we have a patent on it.”
The company has such confidence in the product that it offers
a 25 year mould-free guarantee.
“It will seal and bond all materials, says Price. So in use it can replace five or six other products,
greatly reducing waste. Also, it
contains no solvents and when
you are finished you can clean
up the job with nothing more
than a damp cloth.”
He claims that the multi purpose
polymer from the sealants range
will do everything the IPT does
only outside and what is more it
will adhere to wet surfaces.
The company is already making headway into the UK trade
markets. Stacks wholesale
builders will be carrying the
Graft range and Polyseal has the
country's two largest electrical
wholesalers on board. The website lists a dozen other distributors. Graft is also available
through Amazon. In April there
will be a TV campaign and an
App is planned for on-the-job
product selection.
“The problem with sealants,”
says Price, “is that you never
know what is in the tube. If you
buy simply on price then you
could be getting a lot of filler and
not much sealant. If you consider
that every manufacturer starts
with a cost of around 40p for
packaging, working out how
much they spent on the the contents is hardly rocket science.
“With our manufacturing experience and R&D behind us we
have been able to take the best
of our technology and put it into
our own brand to offer a premium range at competitive
price.” i

Specialist Packers
for the Expert
ost high volume
window fabricators
and system houses
use a form of Flexi
Corner Glazing
wedge of some
form.
These wedges replace flat
packers for the packing out of
glazed units into the frame but
that’s where the similarity ends.
The flexi corners are generally
supplied flat so when flexed into
90 degrees they are placed into
the frame corners. Once the
glazed unit is in place on the
flexi corner wedges are placed
at each and using the side of a
properly designed glazing
shovel the wedges are tapped
into place horizontally and vertically. This toe and heels the
glazed unit which is essential for
large or moving glazed units.
According to Andy Clegg, Tech-
M
nical Director of
The Fenestration
College:
"The
flexi corner is
technically the
best way
to toe
and heel
glass.”
Not
only is
the installation
of the
glazed unit faster, the packers
are installed in the correct position 60mm from the frame corner as detailed in BS6262, their
use reduces the number of call
backs for dropping glazed units.
The packers can be profile specific but general designs
are available for many glass
widths (20 mm to 32 mm) and
stack heights e.g. A wedge can
be from 1 mm to 3 mm or 3mm
to 5 mm. i
Klip and spring frame packers free up your hands during frame fitting. These
packers are designed to address the problems of using a traditional
horse shoe packer. They are for use during the installation of the window
frame into the window reveal, exactly as with a flat U or horse shoe packer.
The problem with these traditional frame packers is how many are lost as
you fight the window frame to get it true and try to hold the packers in
place? Many just end up either on the floor or inside the cavity wall!
However, these designs incorporate either a 'spring' or 'klip' function and
in the latter an installation 'tab'.
The packers with a 'spring' incorporated are designed for use during
the installation of the window frame into the window reveal, exactly as
with a standard frame packer. However, the design incorporates a 'spring'
function. This spring exerts a lateral force between the reveal and the window frame
supporting it in the gap. The advantages of this design are that once in position it can be released by
the installer, freeing up a hand to install the fixing correctly, easily and safely (especially when working at height). In addition this prevents the frame packer rotating and falling out as the design supports the fixing above and below the fixing.
The 'klip' design exerts a lateral force between the frame packer and the fixing, holding it in place
preventing any rotation of the frame packer and it falling out. The addition of a tab makes the location of the frame packer even easier, especially when working at height and once the window is in
position the tab is bent over, breaking off. i

Multi-Material
Windows Sealed
A
new development of
student accommodation in Edinburgh, designed by Richard
Murphy Architects, is
nearing completion, with products from the range of tremco illbruck being employed to install
and seal the high performance,
composite window systems which
project from the elevations in steel
frames.
Holyrood South, constructed by
Balfour Beatty, stands by Holyrood Road in Edinburgh’s famous
Old Town. It offers a total of 249
en-suite student bedrooms
arranged in groups for four, five
or six persons with the living accommodation gaining natural
daylight through Velfac windows
which are being fitted by specialist installer, Keyes Brothers.
Both the South block and the
larger Holyrood
North have been designed to achieve a
BREEAM Excellent rating with window energy performance
contributing significantly to the thermal
integrity of the building envelope. Accordingly, TP450 has
been supplied to
Keyes Brothers for weather sealing the steel window sub-frame
units to the precast concrete wall
sections with ME501 making the
air seal in the same area. Additionally, TP600 was utilised to
seal around aluminium flashings
where they cover the perimeter to
the Velfac windows.
Director of Keyes Brothers,
Colin Keyes said: “Products like
illbruck’s TP450 TP600 and Duo
HD membrane are simple to
apply and offer very reliable performance while the manufacturer
always provides good technical
support where it is required.”
Also employed by the contractors was SP525 which was chosen for its achievement of a long
lasting, low modulus seal able to
form joints subject to significant
movement characteristics. i

Installers can keep spaces sealed and watertight with Geocel’s Airblock low expansion flexible foam. The polyurethane, one component product
is versatile and suitable for use on an array of substrates from wood, concrete and
brickwork through to plaster, plastic and metal. It’s a highly effective barrier that provides significant improvements to energy efficiency – insulating against sound and heat
loss. It has a moisture-curing formulation giving low expansion delivery – cutting the
risk of distortion around joints and frames.
Once dried, Airblock guarantees a flexible and hard-wearing seal that resists cracking, even during the natural expansion and contraction of common building materials.
Fire rated to DIN4102-1 B2 and rain tested to EM027, it can be used to help soundproof any commercial or residential property, offering an acoustic rating of 60dB to
EN IS0717-1.
Meanwhile, Dow Insta-Stick MP is a fast, fuss free adhesive that takes the pain out of
even the trickiest maintenance jobs. Suitable for fixing plasterboard, insulation and
other common building substrates, its formulation means it can be applied to surfaces
straight from the can. Its handy 750ml container offers tradesmen as much adhesive
power as a heavy 25kg bag of dry, mixable product.
A polyurethane, multipurpose, low expansion product, with a cure time of only a few
minutes, Insta-Stick MP allows for plaster boards to be fixed just one hour after use, removing the need for visible wall fastenings. i
