30 years ago, most windows were timber and maintenance was a major bug-bear. There was almost no requirement for thermal or sound insulation, glass was single glazed, little concern existed for the environment, or security – and the concept of ‘whole life costs’ and thus, ‘best value’, was just a dream in the minds of the more enlightened.

Since then, the introduction of PVC and aluminium windows to reduce maintenance, worked well for a while, but then, these new window materials began to struggle under the inexorable rise in performance requirements under Building Regulations, ecological considerations, global warming, architectural preferences and clients wishing to exceed these performance standards, even further.

Thinking outside the box and using synergy, a ‘smarter’ solution was developed by some industry innovators, exploring better uses of current materials.

Timber, despite its susceptibility to water, has many benefits of sustainability, inherent insulation and acoustic properties, ease of workability, and a desirable appearance – and when engineered into laminated profiles, becomes extremely strong and dimensionally stable (Example: Structural “H” beams).
Aluminium on the other hand, is a very poor insulator, and lacks the appeal of a warm internal finish, but makes an excellent water barrier.

So, combining the two and making an engineered timber window, with all those added benefits, but protecting it from water, by fitting an outer shield of aluminium – and the “Composite” Window was born – which has since become a legendary revolution in the industry, outpacing the growth of all other window types, in recent years. This applies equally to progressive designers of Schools and Student Accommodation, since long life, minimum maintenance, low U values, high acoustic attenuation and competitive pricing are all essential.

One of these leading pioneers, in the mid 1980’s, was the Uniform Group, in Italy, who manufacture exclusively, the uni_one® Composite Window System, which, today, sells all around the World.

Introduced into UK, in 2014, through Uniform Architectural Ltd (a wholly-owned subsidiary of Uniform) the many benefits of the uni_one® system, even over other composite windows, have been welcomed and appreciated by clients, architects and contractors, alike. Many unique features set uni_one® apart, as follows:-

Examples –
A) Structurally bonded glass to improve strength and rigidity allowing much larger sashes to be produced, which architects and clients often prefer.
B) Vulcanised gaskets providing a continuous seal around the glass corners for much better and more durable weather-sealing.
C) Internal timber profiles are veneered in a variety of finishes, to provide significantly longer life, durability, appearance and protection from wear and tear, especially in heavy duty applications.
D) Unusually high acoustic performance, avoiding the need for secondary glazing is available beyond Rw50 and especially suited for traffic noise attenuation.
E) Triple glazing can take U values down to well below 0.8 W/M2K.
F) Sheer quality of manufacture of the finished product, cause many customers to ‘adopt’ us as their preferred window supplier, recommending us to their clients on future schemes.
G) Cost advantages over others on Tilt & Turn windows, due to economies of scale from high volume manufacture across Europe.
H) Cost advantages over aluminium-only windows, whose increasing raw material prices now make them more expensive than our composite windows, very often! Ironically!
I) An enthusiasm and passion by all within this Italian family owned business, to make the best window on the market; to embrace customer’s special requirements and strive to meet their needs.

Profile 22 has launched a unique externally Flush Tilt-Turn window system designed for commercial applications, especially medium and high rise buildings. The distinctive sleek, urban and modern design of its flush exterior frame avoids the overlapping of framework associated with conventional PVC-U systems, making it especially suitable for applications such as new-build apartments, housing hotels, offices, universities and colleges.

The Profile 22 externally Flush Tilt-Turn can achieve A++ WER Rating (U-Value 0.8 W/m2.K, in line with Passivhaus standards) with argon-filled triple-glazed units, due to its energy effi-cient six-chamber sash and five-chamber outer frame as well as the inclusion of Profile 22’s innovative Aeroframe thermal barrier. This window design offers superb thermal perfor-mance thus eliminating the need for expensive krypton-filled units. The high performance weather seal system allows for more efficient drainage of water, greatly improving weathering and thermal capabilities.

Profile 22 Commercial Sales Director Andrew Reid said: “The externally Flush Tilt-Turn offers sleek simplicity in its appearance, combined with the functionality of the tilt-turn and the high specification that can be expected from any Profile 22 product, making it the ideal choice for commercial applications of all types. It offers the benefit of a clean finish internally due to concealed hinges, top opening for ventilation or fully opening from the side for cleaning the exterior from inside, and has the option of restrictors for added safety above ground level.”

The Profile 22 externally Flush Tilt-Turn window has a large maximum opening size of 2,300 height x 1,450mm width, with 28, 36 and 44mm glazing options and is available in 28 col-oured finishes.

The tilt before turn (TBT) window from fenestration systems specialists Sapa Building Systems’ Dualframe 75 Si range is the first aluminium window to be given the new A++ Window Energy Rating (WER), the highest available rating in the UK.

Awarded by the British Fenestration Rating Council (BFRC), the rating was originally launched at the start of June, giving manufacturers four months to develop products. However, such is the future proofing strength of Sapa’s Dualframe 75 Si range, the TBT window was already compliant.

The entire suite of windows included in the class leading range all achieve the A+ WER, the only aluminium range to do so. It has continued to push boundaries since its launch in 2010 and Sapa’s commitment to exceeding energy and security targets set out in the Building Regulations and national standards is underlined in the awarding of the A++ rating to the TBT design.

“We are again leading the way with energy ratings for aluminium windows,” said Mark Robinson, Technical Director at Sapa Building System. “This latest award follows on from similar accolades in 2006 when a solution from the Dualframe 75 range was the first aluminium window to be awarded an A rating, which was then followed in 2013 with the Si A+ WER.

“This new addition to the rating system will not only offer fabricators more choice, it will also create significant energy savings, helping to reduce bills. The TBT window will reduce solar gain in the summer while helping to keep buildings warm in the winter. With the next expected revision of Part L of the Building Regulations expected in 2019, we are ideally placed to be able to meet any projected tightening.”

“BFRC is delighted at the take up for the new A++ rating for windows,” comments BFRC Managing Director Chris Mayne. “Since the announcement that BFRC was accepting applications for the new A++ band we received simulation reports from far more companies than we expected. This has resulted in the launch of the first batch of A++ window products and we look forward to seeing how they perform in the market.”

The Dualframe 75 Si TBT window is an ideal solution for high rise or commercial applications, and combines ventilation with easy cleaning and large span openings. The safety locking handle is key operated and the key must be inserted in order to access the turn mode. Once the window is closed, it automatically defaults to the tilt only mode.

Leading window, door and curtain walling manufacturer and installer CMS Window Systems has boosted its aluminium division by adding one of the world’s leading systems to its portfolio and obtaining CWCT membership.

The company, which employs more than 200 people at its HQ and main manufacturing facility near Glasgow, has joined forces with Kawneer to become an authorised partner in a move which gives customers access to an even greater range of fenestration and building envelope solutions.

Since its launch almost a decade ago, CMS has enjoyed continued growth as one of Scotland’s market leading design manufacturers and installers of aluminium, PVCu and timber hybrid, window, door and curtain walling systems. The company works with a wide variety of commercial developers and main contractors delivering projects such as newbuild student accommodation, schools, hospitals and commercial offices.

Director of the Aluminium Division at CMS, Stephen Anderson says the decision to join the Kawneer authorised dealer network was born out of the company’s ethos of continual improvement:

“We are constantly investing in our manufacturing processes, design and technology resources to increase production efficiency and make life easier for our customers. We’re also committed to investing in our product range, and becoming part of the Kawneer dealer network reflects this commitment, giving our customers access to an even broader range of architectural aluminium building products and systems from a business that has a reputation as an innovator in the market.”

Strengthening its technical credentials further, CMS has also become a member of the renowned Centre for Window Cladding Technology (CWCT). This reinforces the company’s commitment to delivering the highest technical standards within the building envelope market and its dedication to continuous improvement.

CWCT uses various testing methods, which determine the level of serviceability of a window, façade or cladding system when subjected to various levels of water, air and solid object impact. The final level of certification depends on the pressure reached or the degree of damage caused after impact. The standards that make up the CWCT tests are calculated to give independent verification that windows and cladding designed for the building envelope, will achieve the values expected.

Its membership provides additional assurance to clients and main contractors and sits alongside a variety of key industry memberships and accreditations that CMS currently hold. These range from Investors in People and ISO 14001 at a business management level, right through to Constructionline, CHAS, Secured by Design and Energy Saving Trust recommended status which directly benefit clients

CMS operates from a 15-acre modern manufacturing and recycling facility in North Lanarkshire, with additional facilities in Fife, producing more than 100,000 window units and thousands of square metres of curtain walling every year. The firm provides a 360-degree building envelope solution from design through manufacture, installation and aftercare, an approach that has seen it work on some of the largest housing investment programmes and commercial building projects throughout the UK since its formation in 2006.
