By working with Liniar products, our entire window and door range is fully lead free. There is no lead used in the profile itself or throughout the actually manufacturing process. Such a unique, eco-friendly process is unheard of with other manufacturers.
Both the profile and the glazing we use offers fantastic thermal insulation as standard. With improved heat retention, you may not need to have your heating on as high in winter. Doing so can see you improve your carbon footprint over time.
The uPVC profile used for our Liniar windows and doors is made from fully recyclable materials. Despite this, they still deliver superb thermal and security performances across the board, standing toe to toe with new profiles from other manufacturers.
All our Liniar uPVC windows and doors are fantastically energy efficient. The multi chambered uPVC profile retains the maximum amount of heat, adhering to the latest regulations. Your home will sit at the optimal temperature during winter.
Installing a set of French doors is a fantastic way to connect your Buckinghamshire home to your outdoor space. Opening centrally with a floating mullion, French doors are a timeless, classic option when looking for a wider spanning back door. They can be fitted to your existing home or to a conservatory or extension, providing an alternative means of exit.
Our French doors are designed with a high quality uPVC profile which is supplied to us by Liniar. We then fit each door with our in-house constructed glazing – something which makes us unique for the Buckinghamshire area. The result is a French door of unquestionable quality. They are designed to outperform the competition while improving your day to day life.
Castle Glass work with industry leading supply chains to install high quality aluminium and timber products across the Buckinghamshire area. Explore our individual timber and aluminium pages today for more details about these two stunning products.
Ultion locking systems come with unique technology that will detect if an intruder is attempting to gain unwanted access through the window or door. When activated, a hidden firing pin secures the central cam, fully preventing any forced entry into your home.
The Ultion locks fitted to your new windows or doors are supported by a financial guarantee. If an unwanted intruder does manage to break-in, you’re entitled to compensation of up to £1000. The chances of this ever happening is extremely thin, however.
20 hardened steel pins are fitted into an Ultion lock as standard. They are precisely and individually positioned to specifically prevent an unwanted intruder from using an electric drill to get into your property. No other lock on the market can offer the same.
Our windows and doors can reach Secured by Design requirements when they are fitted with Ultion locks. A scheme supported by the UK police, it lays out the minimum standards for competent home security. Our products comfortably exceed these.
No, there isn’t. All Liniar products come from a manufacturing process that is completely free of lead, while the product itself is also lead-free.
The thick glazing of our French doors will do a superb job of providing great acoustic insulation, meaning you aren’t bothered by outside noise.
These systems can achieve U-values as low as 1.3W/m2k. This is incredibly impressive for a uPVC French door.
As standard, these French doors come with a 28mm double glazed unit. However, there is a 36mm triple glazing upgrade available.
