Quite simply, quiet,
warm and secure.

The sleek, modern design of our secondary glazing systems ensures that you can enjoy all the acoustic, thermal and security benefits, without compromising on style.

If security is your priority, secondary glazing
offers a unique, additional deterrent to
any would-be intruders.

Unlike traditional
windows, secondary glazing is incredibly
difficult to open from the outside and creates
a further layer of defence against forced entry.

Suitable for a range of windows – including
both casement and fixed – our horizontal
sliding units open from side to side and are
slim, versatile and easily accessed for both
cleaning and ventilation. Best paired with:
Any window with vertical bars.

Vertical Slider

Opening from top to bottom, our vertical
sliding units are also available with a special
slide pass or tilt in function, which enables

Hinged Unit

With no transoms or mullions to spoil the

or butt hinges. Best paired with: casement,
patio and large sash windows.

on the inside of the existing door or

the frames to allow for increased airflow and
improved access for cleaning. Best paired

access.

Bespoke & Arched Units

No matter the shape and stature of your
existing window, we’re able to manufacture
custom secondary units to order. There is
virtually no limit to the designs and styles
we can create. Best paired with: Any curved window or a non-standard shape.

From a sound insulation perspective, secondary glazing offers the most effective levels of noise reduction in today’s market, significantly outperforming all other glass solutions.

Our bespoke secondary glazing is manufactured using state-of-the-art machinery to lock in a tightly sealed frame, reducing noise levels by up to 80%.

If draughty windows are of bigger concern for
your property, secondary glazing adds an extra
layer of defence to guard your home against
heat loss. The small gap between your existing
window and the secondary unit effectively acts
as an insulator, creating a separate layer of air
between the two which can reduce heat loss by
up to 65%.
