Window and Door Glass

Door and Window Glass as the major component within glazing comes in a substantial variety of types, quality and specifications. The type of glass for new doors or windows also needs careful consideration.

Depending on the location and requirement, there’s a glass solution for virtually any requirement. Clarity, comfort, energy efficiency, security, privacy, sun control, acoustics as well as specialist use. These are just some of the options and solutions available with today’s glass and glazing products.

Glass performs many functions in today’s modern lifestyles and remains a critical element of all fenestration. Technically, glass has many dimensions and capabilities. It is one of the vital components that enables windows and doors to perform at their best.

Thermally insulated door and window glass

Working in conjunction with thermally insulated aluminium frames or multiple chamber PVCu profiles, modern glass improves the energy efficiency of a dwelling or commercial building.

Brands such as Pilkington K Glass come in more than ten different types. Planitherm is another brand with various glass types offering different energy efficiency levels.

When improving a property, ask about the thermal performance of window and door glass. Importantly, ensure the U-Values or Window Energy Ratings provided represent a ‘whole window’ value and not a ‘centre pane’ value. The latter covers the glass only. Most glass units work in retaining heat in a room while at the same time allowing it in.

Advanced coatings, spacer bar materials, sealants and glass types all work together, creating thermally insulated door and window glass. Insulation starts from products meeting the minimum requirements of Building Regulations up to super high-performance glass units for Passivhaus and low energy buildings.

Security and Safety Glass

Regulations ensure every exterior or interior window and door glass door and windows at low level meet regulations covering the use of safety glass.

Furthermore, substantial options exist for adding extra protection and particularly in large patio doors.

Most domestic doors and windows needing safety glazing come with toughened glass as standard. For products meeting Secured by Design laminated glass is the type provided in testing. Commercial buildings have different needs within commercial entrance doors or curtain walling. Finally, specialist glass includes bomb and blast resistant, bullet proof glass, single vision glazing or products for secure and specialist buildings.

Acoustic Glass

City centre houses, on busy main roads or near airports, especially benefit from acoustic glass.

The construction of these glass units, double or triple glazed usually involves acoustic laminated glass to the inner pane. Alternatively, there are options using one thickness to the outside and another on the inside.

Window and door acoustic glass do not affect daylight levels. Neither does it affect thermal performance. This glass type helps block or absorb outside noise providing quieter rooms around the entire property. All the major glass manufacturers offer different products designed for reducing noise as well as improved acoustics.

Integral blinds for doors and windows.

Modern integral blinds consist of horizontal blinds housed between the two panes of glass on a double glazed unit.

Integral blinds never need cleaning, are hermetically sealed, don’t gather dust or blow in the wind. Above all, they’re one of the best options for bifolding doors.

Using integral blinds also provide excellent solutions in controllable privacy and shade. They also come in a comprehensive range of colours and products to suit window and door glass of most types and sizes. These blinds come as with manual, automatic, electric or sensor controlled options. They even integrate within home automation apps.

Decorative window and door glass

For bathrooms, toilets and general privacy, decorative window glass provides privacy with light transmission and energy efficiency.

Most installers provide a range of modern or traditional patterns. These also come with varying levels of privacy and obscurity.

The range of decorative, patterned or obscure dingo and door glass generally comes with other options. Furthermore, this glass type offers energy efficiency as well as integrating with security, acoustic or self-cleaning glass.

Solar Control Glass

For patio doors such as large sliding doors, solar control glass is effective in reducing heat and glare.

This sun-control glass also comes recommended in glass roofs and windows and doors on South elevations as just some examples.

The sun control features also work with other expected performance in glass. Energy efficiency, security or acoustic glass can combine with solar coatings. The options with this glass include blue, grey or brown tints or specialist coatings. Some loss of light is to be expected, however this type of glass also provides excellent visual clarity.

Self-cleaning glass

For lantern roofs, conservatories and rooflights, self-cleaning glass is a useful addition.

This glass uses specialist coatings and rainfall in breaking down dirt. Additionally, solar control options provide sun protection, therefore helping keep glass rooms comfortable.

Generally speaking, self-cleaning glass won’t provide a fit and forget solution. However, it’s widely regarded as resulting in less routine cleaning of glass. Pilkington Activ™ is just one of the products available.

Glass for Conservatories and Roofs

Whether refurbishing an existing conservatory or constructing a modern luxury garden room. The choice of glass for conservatories or glass roofs plays a huge role in comfort, look and feel.

The right glass solves many of the issues associated with too hot in the summer and too cold in the winter conservatories and glazed extensions.

Choosing the right roof glass ensures better use of the room. First of all is increased energy efficiency and substantial benefits over standard double glazing or polycarbonate sheet. Therefore, older conservatories benefit especially from a simple replacement to a latest generation glass product. Additionally, modern glass provides options for reduced noise, better sun control and even self-cleaning properties. Of course, glass for conservatories and roofs comes in toughened or laminated options for safety and strength.

More information about door and window glass

Always ensure a professional door and window provider discusses the range of glass options available for your windows and doors. The added cost of glass enhancements makes a huge difference to living with new aluminium windows and doors.

It’s especially important for homeowners to understand how different glass affects energy efficiency. Additionally, security and privacy need consideration and the right advice at the research stage of a home improvement project. Overall, glass technology today provides some excellent solutions within modern aluminium frames.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
