What Is Glazing? Types, Benefits

MasticAny of a wide variety of waterproof materials, not limited to sealants. Insulating StripA material used to protect the edges of the glass from rigid contact with non-resilient. Hardcoat Low EHard coat glass is created by pouring melted tin on top of a sheet of glass. Face PuttyThis is the sloping edge of putty from the glass to the frame.
It’s generally cheaper than replacing windows with double glazing and can lead to energy savings by reducing heat loss, which lowers heating bills. Additionally, secondary glazing is highly effective for soundproofing, making it valuable for those living in noisy areas like city centers or near airports. It’s also a practical option for heritage or listed buildings, where altering the original windows isn’t allowed. Secondary glazing involves adding a movable second layer of glass or plastic to the frame of existing single glazed units. Installed on the window’s interior, it’s fully independent and doesn’t form a sealed unit like double glazed windows.
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.

Then, the spacer bars are manufactured to size by double glazing companies to ensure that they separate the two panes to reduce heat transfer and improve thermal insulation. This space is often filled with air or inert gases, which are poor conductors of heat. Double glazing reduces noise by using two panes of glass, separated by a gap filled with air or inert gas, to create a barrier that sound waves must penetrate. This structure significantly dampens external noise as the sound waves lose energy when passing through the different layers and the insulating gap. The thicker the glass and the wider the gap, the more effective the noise reduction.

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.
This is likely to lead to triple glazing becoming the norm in most windows for new buildings or retro fits that want to achieve the highest performance. The Government has outlined its plans to deliver a "zero carbon ready" building strategy through its Future Buildings Standard. It aims to ensure that no new buildings from 2025 will require further retrofitting, with an uplift in energy efficiency standards, improved ventilation and roof light replacement requirements to mitigate overheating in residential buildings. A start was made on this last year with the changes to building regs and parts F, L and O which we have covered in previous blogs . The Future Buildings Standard which is looming over the horizon in 2025 is likely to mean a big increase in the use of triple glazing to meet the lower U-values that will be required.

Because you create stationary air with secondary glazing, the insulating effect will be even better in practice. These are fixed with glazing clips or screws, in combination with insulation tape. We have extensive portfolio of clients, encompassing residential clients, heritage buildings, churches, hotels and commercial offices. We can deal with all types of window styles (including Victorian Sash windows and Crittal windows), which might look beautiful but allow enormous amounts of noise, cold and dirt in from outside.

We are able to combine and/or couple together our hinged & lift out secondary glazing units. These units are perfect for treating more complicated window styles and bay windows. With traditional single-glazed timber windows, Michael wanted a solution that didn't cost a fortune, and one that didn't require a big job. Retro Panes reduce heat loss through your windows all year round and add a layer of sound insulation to your home. A 3 bedroom gas heated house, using an average of kwh of energy per year, saving around 10% of their energy costs through the insulative powers of double glazing alone, stands to save around £70 a year.
