Double- And Triple-glazed Windows Explore Our Windows

This gap, whether it’s filled with an inert gas like argon or left as a vacuum, acts as an insulating barrier which helps keep the heat in and the cold out. Double glazed windows are the gold standard when it comes to thermal insulation, so most homeowners will want to go with this, or at least something that resembles it. Double glazing is a type of window that consists of two panes of glass with a small gap between them. The two panes of glass act as a barrier to reduce the amount of heat that is transferred through the window. This provides increased insulation, which can help to reduce heat loss from your home and improve energy efficiency.
Our expert team is here to help you select the perfect windows for your needs. Visit our showroom to experience the quality of VELFAC products, or reach out to a VELFAC distributor for guidance. Choosing between double and triple glazing depends on factors like your home’s insulation level, environmental impact, and budget.
Electrochromic glassIt works by passing low-voltage electrical charges across a microscopically-thin coating on the glass surface, activating a electrochromic layer which changes colour from clear to dark. EdgeworkA process consisting of polishing or abrading-scraping the edge of the glazing surface. Dry GlazingA glazing process which does not use chemical compounds, only dry, mechanical fixings. CuttingA process in which glass is trimmed, also for decorative purposes. CoatingA thin layer or covering which changes the basic composition of glass.

Secondary sealA sealant applied to the edges of double-glazed units after the primary seal, to provide effective and durable adhesion between the glass components and spacer bar. Each of our quality secondary glazing units is uniquely designed and bespoke to our client. The addition of secondary glazing to a traditional double hung sliding sash window can reduce heat losses by 58%.

For heritage and Listed properties, it allows to preserve the original window design detailing, whilst bringing the thermal, acoustic and safety performance to modern day standards. There's a variety of claims on who was the first to experiment with double glazing but it's generally considered that the Scottish were the first in Victorian times. Adding a second pane of glass to their existing windows to try and keep out the harsh Scottish elements.
If you are interested in upgrading to triple glazed windows, we are proud to offer a variety of styles in our Residence Collection. These windows are the perfect replacement for outdated timber frames, thanks to their classic appearance and contemporary performance. Our triple glazing offers enhanced soundproofing and can achieve u-values as low as 0.8 W/m2K.

Double glazing consists of two panes of glass separated by a vacuum or a layer of inert gas such as argon or krypton set in the same frame. The air gap reduces the thermal conductivity between the two panes, keeping the heat inside and the cold out. Many windows also come with Low-E (low emissivity) coatings on one of the glass surfaces, for improved thermal performance. Double-glazed windows have two panes of glass, separated with a layer of normal air or, for more efficiency, a layer of argon gas. The panes are then sealed to keep the gas contained, creating an airtight, sealed unit. To reduce noise and improve thermal insulation, secondary glazing offers an effective and affordable alternative to traditional window replacement.

Any of our glass specifications can be combined with a 6.8mm laminate pane, which further lowers both the U- Value and FENSA registered glaziers - https://app.readthedocs.org/profiles/scenestudy94/ - solar heat gain and offers increased noise reduction of 30-32db. Shield boasts additional benefits including significantly reducing UV light entry through your glazing, greatly reducing fading of your interior furniture and flooring. In well-insulated homes, however, windows become a key element in energy efficiency, making triple glazing a worthwhile investment. For homes with less insulation, double glazing provides the best balance of price and performance before you need to consider other costly upgrades to walls and roofs. Glazing’s energy efficiency can also be improved by opting for low emissivity glass (aka Low-E glass).
