Explore our Extreme UPVC Windows
With Extreme, we set our sights on crafting UPVC windows unlike anything that had gone before and believe we have succeeded. Achieving an A+ energy rating, Extreme UPVC windows rank as one of the market’s most secure collections and are also lauded for their aesthetics, thermal efficiency and longevity.
UPVC Casement Windows
The side-hinged arrangement of an Extreme casement window allows for a design that provides a single or multiple opening facility. The robust frame removes any need for continual maintenance, and thermally efficient glass sees that the window accomplishes an A+ energy rating.
Security is taken care of, with the windows containing vault bolts, a multi-cam locking system, interlocking hinge bolts and key-locking handles, rewarding you utmost protection.

UPVC Tilt & Turn Windows
From a practicality standpoint, Extreme UPVC tilt and turn windows are a cut above and super-intelligent. Turn the handle with a single twist and it triggers a slight inward opening at the top, enabling controlled ventilation and removing any potential danger for toddlers and young children.
Complete a full turn of the handle on the window being closed and it initiates a full inward opening, handy for cleaning the designs.

UPVC Flush Windows
Timber windows quickly show their age and are a nightmare to maintain. No such issues with our Envisage flush windows, which although imitate the appearance of wooden windows, have a weather-repellent frame.
If you weren’t aware, you could easily be persuaded that Envisage uses a timber profile, but it doesn’t and is crafted from premium UPVC. Envisage outdoes wooden windows in all performance areas, most notably for security and thermal efficiency. Its functionality is also mightily impressive.

UPVC Bay & Bow Windows
On navigating our showroom, Extreme bay and bow windows are bound to capture your attention as they have a very individual arrangement possessing three or more outward-projecting sides. At odds with a standard flat window, the bay and bow window can attract a greater volume of natural light.
Labelled as lounge windows in some instances, bay and bow windows come in rectangular, triangular and polygonal designs, and are typically found in lounge areas. Placed in your lounge, a bay and bow window will offer a captivating view.

UPVC Cottage Windows
Cottage windows hark back to an era when times were simpler, and the craftspeople of the day dedicated hours of work to the fashioning of window designs – much like our designers are committed to doing. They have toiled over perfecting Extreme UPVC cottage windows and making certain they obey the thermal and security needs of the modern household.
For these cottage windows to be regarded as a faithful representation of traditional cottage windows, we knew we had to put in the hard yards to transcend them.

UPVC French Windows
French doors are a staple of continental homes and have a big following in Britain too. Were you aware that you can also have French windows? They’re very alike in how they operate – two parallel-opening vents permit an extensive wide opening.
When the opening is maximised, French windows establish an outdoorsy feel inside a room’s confines, uniting internal and external environments. You often see them in kitchen spaces, where they generally get exploited as a pass-through, highly convenient for social occasions.

UPVC Fixed Windows
Extreme fixed windows are non-opening but are very much focused on maximising an external view from the home and attracting abundant light.
Outdoor landscapes can be observed like never before, wonderfully framed by the fixed windows and their modest profiles. Exceptionally priced and versatile, fixed windows are easily tailored to different sizes and demand only basic maintenance.

UPVC Sash Windows
Our UPVC window collection would be incomplete without a classic sliding sash window. Superb at limiting draughts, you hardly need to do anything to keep the UPVC frame gleaming. Following on from the installation of Extreme sliding sash windows, a rise in warmth will be swiftly detected.
Operating a sliding sash window is a doddle thanks to it possessing tilt restrictors, which let you adjust the window to various angles. Simplified usage can also be credited to the ergonomic handles.

UPVC Shaped Windows
It’s not always the case that a traditional window shape will suffice for a home. In acknowledgement of this, Orion specialises in Extreme arched and shaped windows, amplifiers of views and light gain.
Often seen in Yorkshire properties, Extreme arched and shaped windows have a uniqueness to them and manage to attain outstanding feats of security. Easy to care for, they retain opulence and realise industry-leading energy ratings.

UPVC colours that entice the eyes...
From the first introduction of UPVC windows, white has been the leading coloured finish, but an expansion of colour options has seen offerings like Cream, Irish Oak, Olive Grey and Anthracite Grey close its popularity gap. You’ve also got hues such as Dark Red vying for the attention of replacement door buyers. Gather thoughts on colour via an Orion advisor.

Extreme UPVC window security
Home security simply can’t be ignored, otherwise it invites intrusion. Extreme UPVC windows have the latest secure technology built into them to put a block on thieves transgressing and causing you financial and emotional pain.

Cranked Window Handles
Opening and closing Extreme UPVC windows will become a part of your daily routine and the handles will see that it’s easily done.

Window Hinge Bolts
Our hinge bolts keep the hinge side of the Extreme window sash totally secure, minimising the threat of a break-in occurring.

Herculean Window Hinges
Anyone who attempts to open an Extreme UPVC window with a crowbar will find it’s in vain as the Herculean hinges protect against this form of attack.

Multi Locking Mechanisms
Engaging the multipoint locking mechanism prevents the slightest movement of the window, which is bad news for intruders.
Extreme UPVC window accessories
If you’re taken aback by the extent of window styles, just wait until you get presented with the multitude of colour options and accessories available. Exercise whichever of the possibilities appeal to forge a solution that’s in line with who you are.
Handles that are anything but plain...
Our Extreme UPVC windows rely on smooth-operating handles, which are an essential element of their decoration. You’re welcome to have a feel of some of the handles in our suite of hardware solutions.
The affixed handles are also integral to security and keep the Extreme windows from being compromised by underhand means.
Hardwearing and weather-resistant finishes...
As you browse through the different window handles, bear in mind what colour you feel they would best parade, with several to pick from. Some Orion customers elect to keep the handle colour aligned to the window frame colour, but others prefer that the two colours contrast and be at odds to spark intrigue.
An opinion on colour is never far away – just seek advice from one of our design experts.
The glass is central to window performance...
UPVC Extreme windows harness up-to-the-minute glazing technology, which works in conjunction with the insulating frame to fuel homes with energy and stop them getting cold. Glazing contributes much to looks too and directs natural sunlight internally, as well as in many instances, offers an amount of soundproofing.
Extreme glazing is different to most glasses, surpassing them for standards of thermal efficiency and security. Inquire about privacy glazing if you need windows that will preserve your privacy in certain areas.
Georgian, leaded or astragal bars are worth inclusion...
Any householder who values tradition will be taken with the idea of having leaded, astragal or Georgian bars applied for decoration. Extreme UPVC windows with such detailing exude immense charm and inject added character into the designs.
Extreme windows are an eternal classic and the presence of Georgian, astragal or leaded bars will reinforce that.

Extreme UPVC windows are genuinely groundbreaking, establishing a new benchmark...
Regular UPVC windows trail way behind Extreme UPVC windows in overall quality, justifying their name. Built to be considerably stronger and considerably more secure, an Extreme window comes with a significant product guarantee, 10 years longer than the usual cover – 20 years long in total. How is that for peace of mind!
The secure components in Extreme UPVC windows are significantly more advanced than those in non-Extreme windows, and they contain A+ energy-rated glass so that you benefit from the finest level of thermal efficiency. The upshot of this will be a warmer living environment and cheaper fuel costs.

Did you know our windows & doors come with a 20 year guarantee?
That’s double most other companies offer for their window & doors – giving you total peace of mind.
