Patio doors and windows

There’s nothing more beautiful than the natural world and nowhere more special than the part of it that you call home. When you connect to the beautiful world outside, you live better, every day. By bringing light, air and views inside, you can enjoy all that nature has to offer.

We designed our oak bifold doors, aluminium patio doors and bifold windows so you can effortlessly enjoy an inside-outside connection. Drawing on our experience of developing the world’s best bifold hardware systems, we were able to look at Centor doors and windows as a whole – not separate, individual elements like panels and frames and hardware.

We use concealed hardware to remove visual distractions between inside and out, so even when the doors are closed you can enjoy views beyond. Centor’s engineering excellence ensures that our doors protect your home from the elements, that they are secure and able to smoothly glide open as soon as the weather allows.

With Centor, you can create a true inside-outside living experience, without any of the traditional compromises.

Centor offers the best retractable fly screens for bifold doors, accompanied by innovative sun shades that are also built into the frame. Available on our 200 and 400 Series doors and windows, this unique offering allows homeowners to enjoy inside-outside living without the traditional compromises associated with large openings – insects, glare and loss of privacy.

Homeowners around the world are delighted with their built-in screens and shades. In Derbyshire, Deb is surprised at how much she uses the screen: “Although there are a lot of midges near the moorland, we really didn’t expect to need it very much. It’s been so useful though – even in England!”

While in County Durham, Gillian is pleased with her built-in shades: “The integrated blinds really appealed to me. I didn’t want any curtains in my house, but I wanted the capability to occasionally block the light out and to close the windows off at night.”

Our built-in blackout shade also enhances the thermal properties of the door, with independent tests showing a reduction in the U-value by 17%.

Production of Wooden Patio Doors

Material Selection – Patio Doors of uPVC, Wooden–Aluminium or Wood

Whereas, in the past, the manufacture of patio doors was strictly limited to woods of different sorts, today we are able to offer a range of different material alternatives.

Should I have a light uPVC material for my patio doors, long-lasting aluminium, elegant wood-with-aluminium or is classic wood the right choice for me? This is a question that quickly arises as soon as one has decided to have a new patio door.

When choosing the material for patio doors a number of criteria must be observed

On the one hand personal taste and credo help decide, on the other hand on selecting the material for your patio door some criteria must be considered. For example, when fitting inside a protected building it could be that the local authorities insist that only wood may be used for your patio door. At the other extreme there is no sense in fitting a wooden door to a weather-prone facade which is not often used and difficult to reach. This means that the necessary maintenance intervals for repainting are not always met, leading to a faster aging and deterioration of that element. And, often the initial price of the patio door plays an important role.

Window or Patio Door

If one only considers patio doors in terms of their function and technical construction then, at first glance, there are a lot of similarities with those of a window. This is one of the reasons why patio doors are also thought of as being French windows or balcony window/doors.

However, if one looks at patio doors a little more the a number of details and characteristics will be noticed that differentate patio doors from a window.

The most important differing criteria is that patio doors are always fitted from the floor, at all times providing simple and easy access to the outside whether it be onto a balcony or into the garden via a patio area and, in the ideal case, also barrier free.

Additional supplementary constructions, e.g. locking clamps, door threshold sills of aluminium, door motor/ side door function, additional locking points for fittings and lockable handle systems make it possible to configure every patio door individually to sduit every purpose and adapted for every situation.

Windows, on the other hand, serve to air the room, provide light to the interior, enable one to look outside and are usually fitted approx. 90 cm high into the masonry. In some cases they may be fitted with a fanlight with glazing or panel.
