Thermoshield Windows Ltd

As we manufacture windows in our own factory, you can design your own style if you choose. We use Rustique profile from VEKA/WHS Halo, one of the industries most respected companies. Our profile is 5 chambered for maximum thermal efficiency and rigidity. We use A rated double glazed units and the latest in high security multipoint locking to ensure your home is not only snug and warm, but also extremely secure.

With new techniques, more colour options for your new windows are now available to suit any type of home.

Our window styles go from simple fixed panes to vertical sash windows that faithfully replicate the design and functionality of the originals but with the addition of clever easy clean openers and of course virtually maintenance free frames.



Thermoshield offer upvc doors, aluminium doors and composite doors. 

We are proud to be distributors for the Rocal range of solid wood core composite doors.

Our doors are available in a wide range of styles and colours with many glass options. All have high security multipoint locking with electronic and biometric lock options available.

Door styles are subjective, which is why we invite customers to visit one of our showrooms to see and try the various types of doors available. 

We offer a range of doors including front, rear, French, patio, bi-fold and stable door. There is even a "door and a half" for wide opening which require easy access.



In years gone by, a conservatory used to be a room which was too hot in the summer and too cold in the winter! Not any more. With the development of new materials, a conservatory can now be a room for all seasons and all reasons! From a simple mediterranean style lean to to a "grand designs" orangery, Thermoshield can help you design a room which will become a seamless part of your overall living space. 

There are now many different types of conservatory available with a vast choice of glazing, roofs and colours. 

New additions to the Thermoshield range include the "Livin Room", the "Loggia" and the "Garden Room" 

Our experienced conservatory consultant can sit down and discuss exactly what your dreams are and translate them into reality with the help of our  computer design software.

From a loft conversion to a complete new build house, Thermoshield Construction will help you plan and budget for the project. 


Homeowners who do not have Thermoshield windows and doors can still take advantage of our skilled engineers to repair, adjust and replace. Customers are also able to order spare parts for self installation. From a failed (misty) sealed unit to a broken door lock, our dedicated service department is here to help. Unlike some companies whose installation teams also carry out repairs - which can result in you having to wait, sometimes for weeks - Thermoshield have a separate service department. Created to look after our many council, housing association and blue chip clients, the service department is also available to the private homeowner.


Federation of Master Builders

Our building division was formed  to look after folk wanting additional home improvements. We found that our existing customers also wanted to be able to use  a company that they knew and trusted.

As our existing conservatory groundwork teams were all experienced tradesmen, the further step to offering a complete building service was not difficult.

We are now able to offer a whole range of building services from the installing of an understair wc to a new house build.

We can also provide a complete landscaping service from plant pots to patios.

Thermoshield offers the additional reassurance of being a member of the Federation of Master Builders.

"Buy your last cills first" - explaining the strapline

When they designed the DecSTONE™ Window Cill and Skirting range nine years ago now, the company wanted to create a good looking, easy to install option that would add genuine value and prestige to the boxes of glass and plastic that prevailed at the time.

And have they succeeded? Yes, they have!

DecSTONE™ is known in the industry as a reliable and durable alternative window board, that draws admiring comments and adds huge perceived value to any project.

So how do you and your customers 'buy your last cill first'?

Quite simply DecSTONE™ has eliminated the problematic end caps and joint spacers which cuts out the service call outs. They have  used premium moisture-resistant substrate as the core to prohibit any movement caused by damp (or heat), and then  created a stain resistant and durable composite which can even be cleaned using a bleach.

In short they have  given you the DecSTONE™ 10 Year Guarantee.

And a lifetime guarantee of a good looking finishing touch that will set you apart from the rest.

Joining the successful installers of DecSTONE™ is easy. Just request your DecSTONE™  Information Pack by email ( or by calling us on 01268 777555

Fire Escape Ladder


Our Fire Escape Ladder is a permanent, but collapsible safety ladder for emergency use in case of a fire in your home. It will help you and your family to escape quickly, easily and safely from an upper story window. Once installed on an outside wall of your home, the fire escape folds away neatly and discreetly to resemble an unobtrusive rain water downpipe.

 It is easily installed, fully weather resistant and maintenance free. The unit comes fully assembled complete with all fixing bolts and detailed instructions.

New home Building Regulations now make it essential for an escape window to be installed, with a clear unobstructed opening of 850mm high x 500mm wide, as a minimum requirement. In the case of fire this exit would need to be used if safe exit from the ground floor is not possible.

The Fire Escape ladder is the simple yet safe way to exit the house.
