Choosing the right aluminium windows
for your home is an important decision.
An investment that makes a real
difference to how warm and secure
you feel, as well as improving the
look of your property. That is why we
have carefully designed the Prestige
window and door system to combine
stylish looks with the latest technical
innovation. Building on years of
experience, we’ve incorporated many
unique features to create an incredibly
thermally efficient, secure system, with
unparalleled aesthetic appeal, that’s
available in a wide range of colours.
Built around our innovative Thermlock®
multi-chamber thermal break, we
use a patented, strong and durable
construction method, enabling us to
hand tune each corner, ensuring every
single window and door is finished to
the highest standards.

Exceptional thermal
performance combined
with refined looks
Each Prestige installation is individually
tailored to the exact requirements of
your property. A range of different outer
frame sizes accommodate different
plaster lines and window reveals -
ensuring a perfect, neat finish. Our
versatile 72 - 80mm wide system is
available in casement, French, tilt & turn
and fixed windows, single and French
doors, and has been designed to be
sympathetic to the modern trend for
light, airy interiors. Using slim sashes
allows more light to flood into your
home, helping create that important
sense of space and tranquillity.

Prestige combines aluminium’s clean lines with exceptional thermal performance
for up to an A+ Window Energy Rating.* Our innovative Thermlock® multi-chamber
thermal design, hidden away inside each window and door, helps keep you and your
property well insulated against the worst of the UK weather. This closed-cell, insulating
chamber acts as a thermal break and works in conjunction with high performance
glazing to create class leading thermal performance, far superior to traditional
polyamide thermal breaks. Sheerline’s cills also feature this same technology coupled
with innovative in-built weather sealing keeping draughts and rain safely outside.

as a U-value, measures the rate of

a window is, the lower the U-value
will be.

Our patented† corner jointing method

maximising the inherent strength of
Sheerline’s aluminium construction.
A full depth eurogroove also enables
us to offer the latest high security,
multipoint locking - helping keep
you and your home safe and secure.
Additional features like unique hinge
protectors also help create exceptional
levels of security. Prestige’s clever
integrated design also ensures both
window and door lock cases are fully
enclosed, meaning they don’t break
through into the glazing, or beading
areas - which could weaken the
integrity of the frame. So if you are
looking for extra peace of mind as
standard – then we have you covered.
