We clarify all the pieces you could know in our final information to architectural glazing.
Varieties of architectural glazing
In the event you’re in search of one thing greater than your common window, or set of bi-fold patio doorways, what are your choices for architectural glazing?
Edward Stobart, technical gross sales supervisor at IDSystems, explains that architectural glazing can “contain a single glazing product, equivalent to glass curtain walling, or a mixture of programs, equivalent to glazed gables, doorways and home windows, to realize the specified look and usefulness.”
Nevertheless, every sort of architectural glazing has its personal set of design benefits:
- Oriel home windows – A sort of window that extends past the principle wall, supported by corbels or brackets, including character and additional inside house
- Curtain walling – A hard and fast-frame glazed display that may embrace opening components like window sashes and entrance doorways, or be built-in with sliding and bifold doorways

Selecting the best body materials
The selection of framing materials on your architectural glazing performs a vital position within the look, power and thermal efficiency.
Metal is a typical selection however in line with Steve Bromberg, MD of Specific Bi-Folding Doorways, aluminium is doubtless one of the best materials for architectural glazing. “It’s obtainable in any color, is slender and powerful – excellent for large-format glazed merchandise. This is the reason all massive metropolis buildings use aluminium all through,” says Steve.
“Aluminium, timber or alu-clad are all robust body supplies that enable for giant expansive panes and customized shapes, together with commonplace rectangles and squares, in addition to circles, ovals and triangles,” says Matt Higgs, MD of Klöeber.
“Superior chopping, becoming a member of and bending strategies additionally enable for curved, arched, and freeform designs,” he provides.
Steve Bromberg is the Managing Director of Specific Bi-folding Doorways, an organization he co-founded in 2007, which has since grown to be a nationwide firm with a formidable turnover and vary of merchandise.
Matt is the Managing Director of Klöeber, offering bespoke doorways and home windows to self builder’s and architect’s nationwide.
Components influencing price
Architectural glazing is a major funding, and whereas “it may well create an nearly frameless look in sure areas, enhancing the sensation of openness in an area,” says Bruce Moore, “it’s sometimes dearer than commonplace home windows and doorways and requires extra planning and coordination between householders, architects, and contractors.”
The three essential elements influencing the price of architectural glazing are:
1. Kind of glass
“Laminated glass could also be required for safety causes, however in massive codecs, it must be thicker, making it costly,” says Steve Bromberg. “Triple glazing is great for warmth retention, however as the dimensions will increase, so does the thickness and price. Moreover, full-height glazing above the bottom flooring should be thicker because it acts as a security barrier, including to the expense.”
2. Labour and set up
Massive glass panels require cautious dealing with, usually necessitating lifting tools, scaffolding and even cranes. Moreover, fastened home windows are usually extra inexpensive in comparison with panoramic sliding doorways.
3. Type and efficiency
“The extra complicated the form and the extra efficiency enhancements required – equivalent to thermal effectivity, photo voltaic acquire management, sound insulation, and safety – the upper the value,” says Jonathan Story, Residential Market Supervisor at Schüco UK.
“Making a flat glass wall with no shifting elements could be on the decrease finish of the associated fee spectrum, whereas formed, angled or curved shifting components would enhance prices.

Due to this fact when specifying your architectural glazing, there are subsequently a complete host of extra design options you will want to think about to make your glazing work simply that little bit more durable, and in addition stop your areas from overheating.
- Photo voltaic management – The kind of glass and its placement affect the necessity for photo voltaic management options. “Whereas photo voltaic management glass equivalent to Low-E, tinted, or reflective glass reduces warmth and glare, exterior shading or blinds also can present extra management,” says Matt Higgs. “In high-exposure areas, these options improve consolation, privateness, and power effectivity by managing gentle and temperature.”
- Thermal effectivity – Vitality environment friendly home windows are a key consideration when choosing architectural glazing. “Go for double or triple glazing and solely select frames with low U-values,” says Matt. “Timber frames are naturally insulating. Low-emissivity (Low-E) coatings minimise warmth switch and tinted or reflective coatings assist regulate photo voltaic acquire. Positioning home windows strategically and integrating shading options additional improve effectivity.”
- Sensible expertise – Architectural glazing is evolving to combine sensible dwelling options, explains Matt. “Applied sciences like glass with hydrophilic coatings which permit self cleansing are helpful in hard-to-reach areas like rooflights or gable glazing,” he notes. “Triple glazing with argon gasoline improves insulation over double glazing. Many merchandise now embrace sensible locking mechanisms, motorised rooflights, and automatic blinds that sync with dwelling automation programs.”
Constructing laws and architectural glazing
“There are a variety of constructing laws which are in play when designing architectural glazing,” says Edward Stobart.
“The extent to which they have an effect in your design will differ relying on what you’re constructing, the orientation of the home and even the place you’re within the nation.”
In keeping with Edward, essentially the most related constructing laws necessities for glazing as follows:
Half L – Conservation of gasoline and energy: This covers power effectivity for brand new and current buildings and to adjust to this you will want to have the ability to present that the thermal efficiency of your chosen glazing meets the required requirements. Thermal effectivity is measured in U-values and the requirements required will rely upon whether or not you’re constructing a brand new home or making alterations to an current property. Half L may affect the design of your architectural glazing as a result of it lays out the utmost quantity of glass that may be integrated right into a design, based mostly on a proportion of the ground house.
Half Q – Safety in dwellings: This covers dwelling safety and can affect the glazing specification required. As a rule, this implies becoming safety laminate glass on the bottom flooring of new-build properties to enhance the safety of the home windows however this glazing specification is commonly utilised on different varieties of initiatives too, notably in city areas.
Half F – Air flow: By way of glazing in a home setting, this authorized doc ensures that sufficient air flow is offered for the residents of a home. This permits for the extraction of water vapour and air pollution from a house to make sure the property stays liveable. Usually new home windows and doorways are required to include trickle vents to offer background air flow, until another methodology of mechanical air flow equivalent to MVHR is current in a home. Having the ability to incorporate trickle vents might affect in your selection of glazing.
Half O – Mitigating overheating: Given the massive proportions of glazing, Half O is an extremely essential a part of constructing laws to bear in mind when contemplating architectural glazing for a residential undertaking. At the moment, Half O solely applies to new-build properties and locations essentially the most stringent restrictions on south-facing elevations in areas deemed to be most at excessive threat, predominantly in London.
