Casement Windows
Our flush casements retain traditional design
whilst packing in all the modern benefits of
weather proofing, security energy efficiency.
This includes larger rebates to accommodate
double or triple glazing, draught sealing and
high security multi-point locking hardware. As
with all our windows the timber used is
multi-layered, engineered timber and as standard
the windows are double glazed with argon filled
24mm units (Ug value of 1.1W/m2K).
We manufacture two styles of flush casement, the
performance window which has a higher spec in
that it is able to house triple glazing and
accept aluminium cladding and our conservation
window which has very unique styling that you
will not find anywhere else.
The slim line sashes are set back in the moulded
frame which enhances the appearance of the
windows and adds to the design of your property.

Tilt Turn Windows
Our tilt and turn casement option has been
developed tested to meet Passiv Haus
Standard. If you are requiring optimum
performance this is the solution you require.
This window combines perfect performance
parameters and a very low heat transfer
coefficient. The overall heat transfer
coefficient value for the test window achieved Uw
0,8 W/m2K, which means that the window can be
used for high performance eco house construction.
The design also provides increased acoustic
performance which insulates 34-db as standard
with an option to sound insulate up to 42-db with
enhanced glazing options.

Features
High performance German WINKHAUS Tilt turn
hinges fitted to allow for maximum performance
and durability. The tilt position allows the
window to hinge from the bottom and partially
open for ventilation and the turn allows the
window to fully open from the side. Locking
handles are fitted as standard in a range of
finishes. A concealed ventilation system can be
incorporated for compliance with Part L. Our
high performance paints and stains will maximise
the life of your windows allowing maximum
duration between maintenance. Unlike re-painting
in the past the re-application of finish does not
require laborious scraping and sanding. Modern
micro-porous paint systems allow the timber to
breathe preserving the integrity of the wood.
When the time comes a light sanding over the
window will provide a key to reapply the top coat.

About Us
We have a formidable portfolio of designs to
offer some have been included on this website
though space and commercial consideration have
kept us mindful of the need for brevity. This
being said, even in our broader catalogue of
designs, you still might not find the joinery
component that perfectly suits the needs of your
project. Dont be disheartened, the chances are
that we will be able to custom build a solution
for any realistic concept that you, or your
architect, might conceive. About UsOur design
team, working both traditionally and with the
latest computer modelling techniques are at your
disposal for that special item for which a
supplier might be difficult to find. Our methods
are straightforward yet thorough. We work in many
dimensions when approaching a conceptual design,
not merely "lenght, breadth and depth" the
element of time is integral to any joinery
construction. How long will it last? What is the
likely maintenance schedule? What materials might
age most sympathetically with the items
surroundings? Thought is also devoted to another
important factors, e.g. how would the item best
be transported to site? What is the least
disruptive and most simple method of
installation? What guidance might the fitting
team require? An apparently cost effective design
may fall down on any of these points and push
your budgets into the red both in terms of money
and time. We consider our duty to think about
these points on your behalf and to advise
accordingly.
