• How to choose Cortizo sliding patio doors

    The Cortizo brand name is synonymous with high quality glazing systems and the most popular product are Cortizo sliding patio doors. There are two key products available, the Cor-Vision and the mid-range sliding door product, called the Cortizo 4700. We’ve put together a buying guide, helping you choose the right Cortizo slider for your project

    How Cortizo sliding patio doors differ

    Within the Cortizo sliding patio doors range are two well-known products, the Cortizo Cor-Vision (also available as a Cor-Vision plus model) and the 4700.

    The construction of these two doors is different as is the price. The more expensive is the Cor-Vision slider because this comes with a structurally bonded construction and is made around the glass as a result. The manufacturing is also more complex.

    Therefore, the 4700 model is available unglazed, with the Cor-Vision model only available glazed.

    Available at a more affordable price to the trade, builders and homeowners direct is the 4700 model. This features a conventional dry-glazed design, made in the factory unglazed, with the glass fitted on site.

    One of the key considerations when choosing sliding patio doors is the sightline at the mullion or interlock. The Cortizo 4700 slider comes with a slim 47mm interlock. The Cor-Vision is even slimmer

    How to design Cortizo sliding patio doors

    There are some design differences between these two sliding door models as well as some similarities.

    The 4700 model suits more standard installations and is especially cost-effective as a replacement for dated doors with a more modern alternative. Cor-Vision can also work in replacement applications. However, it’s especially suitable for new build extensions, where the frame can be set into the structure reducing the sightlines even further for a truly minimalist and ultra-slim sliding door model.

    Both doors come with a standard or flush track option, an open corner design and even a pocket sliding door option.

    Looking for steel-look sliding doors? Then the Cor-Vision with its slimmer all-around styling suits industrial and heritage style doors better. Both door types come in the full range of RAL colours, giving you over 150 to choose from.

    Even better, both of these Cortizo sliding patio doors work well inside the home. You can use them as a stylish room divider or separate a conservatory from the main room.

    Both doors come with a single track for when you want a sliding door to go behind a fixed panel. A double-track lets both panels slide. Triple tracks suit three panel doors best, with each panel sliding independently.

    As you’d expect, the security, energy efficiency and weather protection of either sliding door are excellent, giving you and your customers peace of mind.

    Whether you choose the Cor-Vision or the 4700 model, both sliding doors promise high quality insulated aluminium profiles, a premium powder-coated finish, high quality safety glass and excellent manufacturing quality.

  • Why the trade loves Alutech bifolding doors

    One of the most recent folding sliding door brands to provide genuine benefits to builders, installers and the trade are Alutech bifolding doors. Affordable, yet with all the features of premier bifolds at a more expensive price, Alutech bifolds deliver the required look to any property project. Here’s why if you’re in the market to buy aluminium bifolds, Alutech bifolding doors provide several benefits.

    Alutech bifolding doors design and quality

    alutech bifolding doors fitted in a detached house extension

    The latest generation and cutting-edge folding sliding door system, Alutech bifolding doors use high quality aluminium profiles, with a deep thermal break and durable, professionally applied powder coated colour finish. Energy efficiency, therefore, is excellent with the doors providing U-Values or Door Energy Ratings meeting current Building Regulations for your building projects.

    With top-end rollers and guides, locks and hardware, Alutech doors come with a smooth slide and fold action, positive closing and excellent sealing.

    Therefore, with our expert craftsmanship and correct installation, you can promise your clients a reliable bifolding door that’s easy to live with every day.

    Trueglide manufacture this high quality door system in our factory, promising the best fit and finish for a reliable product and one that’s low maintenance. We provide a range of standard colours and our doors come at reliable lead times and competitive prices.

    Where you can use Alutech bifolding doors

    Using a 73mm deep outer frame, Alutech bifolding doors are well-suited to the replacement of old aluminium, PVCu or timber with minimal disruption to the internal plaster line. Of course, this convenient frame depth also makes them ideal for new build installations.

    The design of Alutech means they work as the main door out to the garden on smaller properties. Here, it’s worth configuring these with a traffic door, letting the client using just one leaf for garden access without having to fold the panels back every time.

    Of course, they’re perfect as part of a larger home with more than one door to the garden or first floor inward opening doors. One of the benefits of Alutech bifolding doors is we can make them as matching side or double doors. As a result, your property projects get doors with the same matching lines for utility rooms, downstairs study or anywhere a house would have a door.

    For front doors, we combine these with a decorative panel in a modern or traditional style. Alternatively, there’s a midrail option for glass above and panel below or a fully glazed design such as in a front porch.

    Simple and convenient installation with Alutech bifolds

    Just like the more expensive brands, Alutech bifolding doors come with an adjustable frame jamb, making installation a breeze. The adjustable jamb takes up the tolerance of the door panels and is useful on larger built openings where sometimes there can be inaccuracies across its width.

    The adjustable frame jamb you’ll find saves time on site and creates a better adjusted door set overall.

    Alutech bifolding doors – the styling modern homes and clients expect

    Another excellent reason to use Alutech bifolding doors is for their styling and sightlines. This brand is slimmer than many brands such as Reynaers, Origin, Aluk and Smart Systems.

    The mullion sightline is just 120mm – the same as the German-designed Schuco bifold and with very similar appearance. Alutech bifolds therefore provide an affordable solution to this more expensive product with no loss of features. Even the door panels go up to 1.2m wide and 3.0m high just like the German brand.

    Overall the design of the doors is one that’s contemporary with pleasing flatline appearance to the frame and door sashes. It’s a look that works well both in charachter properties as well as modern homes.

    Security and weather protection with Alutech folding sliding doors

    Alutech bifolding doors meet customer requirements for secure and resilient bifolding doors. The locking system features the Alulock system. Alulock has six locking points as well as a high security star-rated cylinder.

    The locking system provides excellent security to the main leaf . Glass is safety glass of course and securely glazed from inside the door set.

    For the intermediate panels and adding to the great security are lever latches. These are activated by rotary handles and engage bolts at the top and bottom. The rotary handles are designed so as not to interfere with the door panels in the fully folded position.

    Finishing off the doors are high quality lever handles available in five different colours.

    For weather sealing, we use a combination of ledge seals and vulcanized corners that together form two closed sealing contours around the sashes.

    Alutech door combinations

    Alutech bifolding doors come in two panels up to seven folding panels, or even fourteen when parting in either direction. As well as this, there’s the option for a fixed or moveable corner post and even doors designed for internal use with a fully flush track.

    We can make your doors open in or out, in numerous combinations of panels all folding in one direction, or bi-parting with a hinged traffic door on one side and stacking panels to the other.

    Origin aluminium windows

    For aluminium windows, there are two product options. The OW-80 product is the premium aluminium window offering. Its key features are its unique design as a flush casement both inside and outside. Again, no other aluminium window comes in such a distinctive style. As a result, it’s ideal as a contemporary aluminium window or a more traditionally styled casement, fixed or bay window design typical of quality timber windows.

    Also with the OW-80 is its advanced insulation, upgradeable to some of the best window energy ratings and low U-Values. Aerogel is an optional extra, provided to the frame chambers. In combination with the high specification glass, the performance is excellent, helping lower your energy bills.

    When you want slimmer aluminium windows, Origin OW-70 is modern, stylish and with great looks. It has a flush casement design outside with a familiar stepped design on the inside.

    Origin bifolding doors

    Two different bifolding door products are available in the Origin range, meeting solutions for virtually any property requirement.

    The OB-49 is one of the thinnest bifolding doors on the market, with a sightline of just 110mm at the door junctions with all the panels closed. Therefore it’s perfect when the property demands thinner bifolds with more glass and light coming into the room.

    The OB-72 model is more classically styled with 154mm mullion sightlines and is also capable of wider door panels and taller heights. It’s also the model available as a floating or open corner design.

    With both Origin bifolding door models you get the option to create single or double doors. An excellent product to go with when there are other doors in the project and you or your client would like these to match.
