Upgrading Your Interiors and Exteriors

Look no further than International Windows and Conservatories for efficient window installations along with a full range of internal doors. Based in Thornton Heath, Surrey, our team of professionals work hard so that you are completely satisfied with the finished result. 

New uPVC Windows 

To optimise the performance of our new uPVC windows, we use a high-quality system to ensure that the installation is carried out to the best of our ability. All of our windows are manufactured to British Standard (BSI) BS-mark with high-tech security locking systems. They are all internally glazed for maximum security and the windows are fully sculptured and welded. We also sell windows on their own and use all German systems with uPVC.

Quality Doors that Offer Security

Taking an old door out and installing a new one can make all of the difference to your home. Your new door will already be fitted with a high-quality 6-point locking system and anti-snap barrels with internal beading as standard. These are all individually designed with differences such as walls with panels, variation of colour, or with lead and glass. You can flick through our brochure at your leisure and pick exactly what you want. From the day that you place your order, the installation process usually takes about four weeks. Everything that we manufacture or supply is made to measure, including: 

Back Doors | Sliding Patio Doors | French Doors | Stable Doors | Bi-Folding Doors | Reinforced Doors and Panels | Exterior Panelled Doors | Composite Front Doors
