Hazlemere Sculptured – An Exclusive Aluminium Double Glazed Casement Window System Designed By Hazlemere Windows

Hazlemere Window Company’s technical division was able to draw on over thirty years of industry experience and expertise, using their know-how to produce the Hazlemere Sculptured Aluminium Window’s advanced technological design, as well as into to its operation, aesthetic appeal and optional features.

Secure “Hidden” Locking System

The Hazlemere Sculptured locking system is made up of three locks, which comprises of two shoot bolt locks at the top and bottom of the window and one central lock. Another unique feature of Hazlemere Sculptured aluminium windows are that they have a “Saracen” locking system, which is hidden within the opening vents, so is visually more aesthetically pleasing than most aluminium, UPVC and timber vents, whose locking systems can be seen on the side of each side hung vent when open.

All Hazlemere Sculptured whose design incorporates either top hung or side hung opening vents have a lockable night vent facility enabling them to be locked in an open position to allow air flow, but whilst still delivering a decent level of security.

The Hazlemere Sculptured window system has matching, high security external glazing beads on all the opening vents and on all the fixed frames.

Attractive Aesthetics

Every Hazlemere Sculptured aluminium casement frame is 75mm deep as standard and it is a direct fix product for greater security and far better thermal efficiency. Visually an ideal wood replacement double glazed window system, the Hazlemere Sculptured aluminium casement window system has a slightly deeper outer sash profile. Its aluminium frames are much slimmer than our UPVC and tend to gain a better aesthetic appreciation hence why so many people buy aluminium windows even though they are more expensive than UPVC. Slimmer sight lines deliver more glass, more light, creating better vision in and out, plus enables rooms to benefit from more solar gain from the sun.

Hazlemere Sculptured features flat mullions and transoms with ovolo edges, as well as an ovolo external raised aluminium sash and moulded ovolo interior outer frame. The raised opening vents and the Saracen hidden locking system are the main design features that aesthetically sets the Hazlemere Sculptured aluminium window apart from other aluminium casement window systems.

Hazlemere Sculptured Aluminium Casement Window System Powder Coated In RAL 7015 Matt Buttermilk

All Hazlemere Sculptured windows have a highly durable powder coated aluminium finish as standard. They are available in any RAL colour, but come as standard in a choice of around 600 RAL colours, some of which are available in a choice of gloss, matt or satin finish. All Hazlemere’s powder coated aluminium products need is a clean with warm soapy cloth roughly once a year to recreate a brand new window look.

Designed With Safety In Mind

Even opening windows that don’t have to have fire escape hinges (By law) come as standard on every Hazlemere Sculptured window (for example they are not required under the current Building Regulations on windows in bathrooms, kitchens, garages and toilets etc.). All side hung vents have hinges that open to 90 degrees, allowing room occupants easy egress in the event of fire etc.

What is more, every side hung Hazlemere Sculptured opening window vent has an “easy clean” operation, so the whole opening vent can be physically moved from one side towards the middle of the window opening to allow for easy cleaning of the external pane and frame, a particularly useful feature on opening windows fitted above ground floor height.

Thermally Efficient and Energy Rated

Every Hazlemere Sculptured aluminium window comes as B-Rated as standard. Under current Building Regulations, replacement windows need to achieve a window energy rating (WER) of “C” or higher. Hazlemere Sculptured achieves its higher B rating by having a polyamide “thermal break” that separates the inner and outer frames, preventing external cold reaching the interior. This technical frame design, when used in conjunction with our standard double glazed sealed unit specification which achieves a tremendous centre-pane U-Value of 1.2 W/m2K, delivers an extremely thermally efficient aluminium window system.

Raised Aluminium Astragal Georgian Bar Option

Yet another unique feature of Hazlemere’s Sculptured aluminium windows is that it that can take a “proper” aesthetically designed astragal raised Georgian bar. Many aluminium window systems can take a flat externally applied bar, but the Hazlemere Sculptured window was specially designed so that it can take a shaped raised astragal aluminium bar externally and internally, so that this window system can exactly replicate the look of traditional single glazed wooden Georgian windows that have separate glass panes. A special “interbar” in-between the double glazing replicate this look on each and every Hazlemere Sculptured windows with dummy vents delivering aesthetically pleased equal sight lines.

The Sculptured Aluminium Window System Is Totally Exclusive

The Hazlemere Sculptured Aluminium Double Glazed Casement Window System is as the name suggests, totally exclusive in every respect to Hazlemere Window Company Ltd, as a) they designed it and b) they are the only company in the World who manufacture it and c) they are consequently the only company in the World who install it. It is not therefore a product you’ve likely to have come across, as only those customers who been into one of Hazlemere Windows showrooms are likely to have seen it. It is one of many different aluminium profiles manufactured and installed by independent double glazing designers, manufacturers and installers, Hazlemere Window Company Ltd.
