energy-efficencyWe specialise in Spectus Windows System
Spectus profiles can be combined to create any style of window and meet any functional need.

Your windows will be designed manufactured and install specifically for your property, to your own finish.

What’s more, all Spectus windows can achieve a Window Energy rating of band A, helping you reduce energy consumption and carbon footprint.

Spectus windows and doors are installed in millions of homes and are trusted by homeowners, builders and architects, for performance, durability and style.


Casements are the very familiar style of window, with outwards opening panes hinged at the top or side. Our window systems can be used to make almost any size or shape of casement window with a combination of fixed and opening panes to suit.

All of our frames are slim, but very strong, and there’s a choice of a classic, bevelled shape or the gentle curve of an ovolo profile. We use impact-resistant PVC-U and multi-chambered sections for insulation. Discreet, permanently-bonded gaskets protect against the weather and multipoint locks provide security for your home.

Tilt & Turn windows are the ultimate in practical design. Their appearance is simple, clean and modern, allowing plenty of natural daylight into your home. Hinged along the base, they tilt inwards for ventilation and if you want to clean the outside glass, simply turn the handle again and the window becomes side-hinged and can open right into your room. They are perfect for high-level or hard-to-reach windows – or for anyone who hates climbing ladders!

Tilt & Turns are not only simple to clean, operate and maintain, they are also very secure, with locking all around the frame. They can be combined with fixed panes to make a large glazed area and are compatible with all our other window and door styles for a matched installation.

Spectus Tilt & Turn windows can achieve a fantastic Band ‘A+’ Window Energy Rating and will protect your home from draughts and leaks. They are available in a choice of colours and woodgrain finishes, creating the stylish appearance your home deserves.

Designed for high-rise or hard-to-reach locations, our Fully Reversible window has proved a hit with the owners of all types of home. The window is hinged at the top, opens outwards for ventilation, and can be rotated so that the outer surface can be cleaned from indoors. The trick is that the window rotates, safely and easily, outside the building, so there are no worries about snagging on curtains or blinds.

The Spectus Fully Reversible window uses innovative AEROFRAMETM technology. This copies the multi-cellular structures of nature to produce strong, but lightweight and thermally-efficient frames. Slimline profiles allow masses of light into your home and the simple line of the deep bevelled frame perfectly complements contemporary décor.

These windows can achieve a Band ‘A+’ Window Energy Rating and help you to keep your energy bills under control. And to keep your family safe, we’ve included child-safety catches and secure, multipoint locking.

  • Panes rotate outside your property

The graceful style of sash windows is difficult to beat. But timber sashes, particularly old ones, are troublesome and require regular maintenance. The Spectus Vertical Slider has been designed to provide the authentic, period appearance without the drawbacks. It’s so good that planning departments have accepted it – even in conservation areas.

When we designed our Vertical Slider, we kept the basics: the elegant proportions and the two sliding panes that are so effective for ventilation. After that, we worked on improvements. Our Vertical Sliders have:

There are optional Georgian bars and sash horns to match original designs and a consistent period look with ovolo detailing to the frame, sash, beads and cills. These are beautiful, sliding-sash windows that are easy to maintain, insulating and secure. What’s more they can achieve a Band ‘A’ Window Energy Rating. Grace and elegance are now combined with performance and all the benefits of 21st century materials and technology.
