You can have between two and seven panels, allowing the option of wide-spanning bifolds that can be designed to stack both inside and outside. What’s more, bifold doors can be fitted to a conservatory, orangery, extension or as part of your home’s existing architecture.

There are many different styles of conservatory for you to choose from. These include, but are by no means limited to: the classic ‘lean to’ conservatory with a slope straight back to your house, the Victorian-style conservatory which adds undeniable elegance and beauty, and the modern conservatory for those with a more functional purpose in mind

uPVC Windows

Installing new or replacement windows can make a huge difference to your home. At Spectrum Glazing, we always ensure that new windows are perfectly fitted, with no heat escaping or cold sneaking in – this could result in big savings on your monthly energy bills.


Our traditional orangery designs will give your home an added touch of class, without making any compromises on security. At Spectrum Glazing, we design your orangery with consideration for the average wind and snow loads in your area, ensuring that the final product is ideally suited to your situation. Ultraframe orangery designs, in particular, give the solidity and infrastructure of an extension, as well as the additional light of a traditional conservatory.

Aluminium Bi-Foliding Doors

One of the most innovative and practical entrance door styles on the market, aluminium bifolds installed by Spectrum Glazing are the full package. Consisting of anywhere between 3 and 7 panels, bifold doors spoil homes with light thanks to an emphasis on crystal clear glazing that blurs together inside and outside living spaces whether open or closed. 

Home Extensions

As part of our extension installation services, we at Spectrum Glazing we fit high performance house extensions in homes across Brightlingsea, Clacton-on-Sea, Witham, Chelmsford and Essex. Contact us if you’d like to get a house extension price

Sliding Patio Doors

Available in either upvc or aluminium our inline sliding patio doors are highly engineered making installation simple and guaranteeing trouble free through life performance.

Roof Lanterns & Skylights

An inherently sleek yet stylish design, lantern roofs and flat skylights are a subtle addition that has the potential to revitalise any darkened areas of the home. They can comfortable sit atop any location that sports a flat roof, improving the aesthetics and thermal retention of properties almost instantly.

Replacement Roofs

Less hassle than constructing an entirely new conservatory, we at Spectrum Glazing give Colchester homeowners the opportunity to revitalise dilapidated extensions with a suite of high-performance warm roof replacements. More stylish and thermally efficient than conventional polycarbonate roofs, tiled warm roofs are a quick but long-lasting fix.

Flush Casement Windows

French Doors

French or Double doors can be a very dramatic addition to your home. Simply, throw open your doors to let the outside, inside. Making your living space airy and appear so much larger. Importantly, although a greater opening area is achieved, security is still assured.
