Superb Flush Windows
Modernise your home

aking its name from the noticeably clean appearance made possible due to a sash that sits comfortably level within the window’s frame, flush sash windows are authentic yet practical. Their design is expertly able to replicate the realism of timber windows fitted in Britain pre-1932, doing away with the original frame’s high-maintenance tendencies and introducing modern levels of insulation.

Casement Windows for Colchester homes

Casement windows are Colchester’s most popular style of double glazing. Defined as a window frame that opens outwards, these modern, versatile systems come with more configuration options than any other style. As a result, they can be tailored to suit a wider variety of functions and styles, while also having customisation options for every style of home here in Essex.

Flush fitting windows for homes in Colchester

Flush casement windows are one of the newest renovations available here in Colchester. As their name would suggest, the profile of these windows is completely flat, rather than protruding like a sculptured or chamfered would. In doing this, flush casement windows deliver similar aesthetics to timber windows and act as a cost effective alternative to real wood frames.

Tilt & Turn Windows

Tilt and turn windows are one of the most modern systems we fit here in Colchester. They operate with a unique profile that allows two different methods of opening. Often a larger, single panelled frame, they can firstly open wide from either side of the framework like a traditional window would. The frame can also tilt inwards within the sash, something which is unique to this style of window.

Sliding Sash Windows

Our sash windows are perfect for traditional properties here in Colchester. Designed to authentically replicate classic Victorian sliding profiles, these systems make for a fantastic renovation option for those living in an older property. A wide range of traditional hardware and woodgrain colour foils allow these uPVC profiles to be almost indistinguishable when compared with real timber.

Bi-Fold Windows

Choose Spectrums aluminium Ultrasky conservatory if you want a system that combines modern styling with natural light to create a beautiful warm and glazed extension. Strength is the secret behind Ultrasky’s success.

A stronger, thermally efficient ridge means fewer bars are needed drawing more light into the room. The Ultrasky roof extends to the eaves beam, rather than a flat roof, and uses the internal pelmet and external cornice to create a beautiful orangery roof style.

Our lantern conservatory roof is compatible with our structural goal post and works with large spans of glass or bi-folding aluminium doors – resulting in uninterrupted views and a stunning conservatory design.

Energy efficient, weatherproof and secure

Our high-performance uPVC windows can improve your home’s energy efficiency, reduce problems such as draughts and condensation, and provide complete weatherproofing against the cold and rain.

Windows are manufactured with energy efficient double-glazed units as standard, allowing them to achieve an ‘A’ Window Energy Rating. To further improve thermal efficiency, we also offer a triple glazed option.

Aside from being energy efficient, our windows are also incredibly secure, featuring high security locking as standard to keep any would-be intruders at bay.

Bring out the personality in your home with colour

Add a splash of colour to your home and let your personality shine through with our range of uPVC window colours and finishes.

The windows are available in an array of colours, ranging from classic shades such as White and Cream through to woodgrain foils which mimic the natural appearance of wood for a low-maintenance alternative to timber.

We can also offer woodgrain on white colour options, creating a different look inside and outside of your home and giving you increased style choice when choosing new windows.
