    When buying any of our aluminium windows, we provide all you need for a fast and easy installation.

    All ancillary profiles such as extension pieces, cills or trims come at cut sizes where available and possible. For those needing extra items, we can also provide packers, silicones and other fixing parts, depending on the product.

    Most competent window installers already have much of what's needed for window installation, but we can help you further when you get in touch with us.

    Depending on the type, size and brand, some windows come to you ready glazed, others require glazing after installation.

  • What types of aluminium windows are available?

    The flexible nature of aluminium windows by Dorsia means virtually unlimited designs as well as a great choice of frame styles.

    For fixed small or large picture windows, any of our products are suitable and available up to the maximum sizes of glass.

    Opening windows come as side or top hinged opening outwards casements.

    We can also provide tilt and turn windows. These tilt back for ventilation. As well as this they open inwards fully, fitting you clean the outside pane of glass from inside the room.

    For frame styles, there's lots of choice. Most people like the contemporary flatline style of windows. But we also offer more traditionally styled casements with chamfered or profiled frames.

    Finally, for a more distinctive style, we've got flush casement windows such as the Origin OW80 product. Perfect as a contemporary window or as a seamless casement thanks to its flush sitting sash.

    The flexible nature of all our windows means they're available at most sizes and designs. And many come with gable heads, raked heads, curved heads as well as corner or box windows and bays.

    For the latest trend in Art-Deco, heritage, Scandi and steel look windows, our Smart Systems Alitherm and Heritage range provides the best solution. Inspired by classic metal windows, this brand gives you the iconic look of slimline classic windows and comes in the desirable black finish or any other colour.

  • Security, energy efficiency and weather performance information.

    Every one of our aluminium windows comes with the latest security locking systems, having multi-point locks and robust handles with key locking.

    Window security is further enhanced with features such as hinge protection and all glazing beads situated on the inside. As a result, the glass can't be removed from the outside.

    For weather protection, our windows come with advanced sealing, keeping windows tight and offering excellent wind and water resistance.

    Energy efficiency is excellent across our entire windows range too. Thermally insulated frames, the latest window design and high specification insulated glass units. As standard we provide 24mm or 28mm thick glass units having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.  For doors and low level glazing, this is also toughened safety glass.

    All our systems come independently tested for security, weather and energy efficiency with full details available upon request for each of our brands.

  • What colours are available with aluminium windows?

    Aluminium as a material offers the biggest range of colour options, thanks to powder coating technology.

    We offer a standard range of popular colours. These include, whites, blacks and several shades of contemporary grey.

    Most of our windows come with a matt finish or high gloss white finish. Other shades are available from over 150 different RAL colours.

    The frame profiles come expertly finished and powder coated. As a result, you benefit from a durable, low maintenance and long-lasting finish. All our windows require is a routine clean with a soft sponge and mild soapy solution.

    If you're looking for something special, check out our metallic, textured and woodgrain finishes, available across much of our range.

    For the window handles, we've got black, white, silver, chrome or gold handles. Origin windows go even further letting you colour match your window handles exactly to your window frames.

  • Things to consider when buying new aluminium windows.

    When buying aluminium windows, you'll want to consider the look and style you want.

    When replacing old PVCu, timber or metal windows, many of our customers replicate the existing design. Others choose to change the look of the property with an entirely new look.

    One of the benefits of aluminium windows is larger window and opening vent sizes. As a result, you get the desirable modern look with fewer mullions and transoms, also resulting in bigger panes of glass.

    Some of our opening window sizes go up to 1.2m wide and high as a top hung opening outwards window. Side hung windows come slightly narrower with widths of 600mm or 800mm possible and at flexible heights.

    Think about how your windows open. First floor windows will require egress hinges providing a valuable escape facility in the event of a fire. If you've young children, you may be thinking about restricting how far your windows open for safety. Here, restrictor hinges provide a great and safe solution. The windows open partially and only by releasing a safety button on the friction stay do they open further.

    The easy clean option lets you open the window then slide the sash to the side. This provides a greater clearance for you to reach through the open windows and clean your glass from the outside.

    Of course, glass comes in several options. We've got a great range of contemporary and obscure glass patterns for bathrooms, cloakrooms and other windows needing privacy. Integral blinds also provide a great solution for privacy and shade. These are permanently sealed between the glass. Even better, they never need cleaning. won't gather dust and don't blow in the wind.
