SECONDARY GLAZING WINDOWS

Arctic Glaze Ltd design and install bespoke secondary glazing that provides enhanced security and increases both thermal and acoustic insulation. Aluminium secondary glazing is a slim and durable window system designed to be installed within domestic and commercial buildings. It is available in over 200 RAL colours and multiple styles to match the aesthetic of listed and modern properties.

What is secondary glazing?

Secondary glazing is a discreet and slimline internal window that is installed within the interior of the building. Secondary double glazing is commonly installed to provide enhanced thermal and acoustic insulation while offering increased security levels. Secondary glazing is recommended to be installed within listed buildings to provide additional insulation for single glazed windows. It can also be found within modern buildings that showcase double and triple glazing as it offers many benefits. Once installed, secondary glazing can help decrease heating costs and prevent noise emitted from close by traffic sources.

Modern secondary glazing is manufactured from durable aluminium and is powder-coated in over 200 RAL colours. Multiple styles are available which allows it to complement all window and property types.

How much does secondary glazing cost?

Secondary glazing is a bespoke product that is tailor-made to match the size and style of your primary windows. It is available in multiple styles and can be installed with various glass types to provide enhanced thermal and acoustic insulation. Depending upon the style, colour and glass specification, the cost of secondary glazing can vary.

The prices displayed are for secondary glazing supply only and are calculated using 4mm toughened glass, white aluminium frames with UPVC trim, face fix timber surround and the window size as shown.

What are the benefits of secondary double glazing?

Secondary glazing is installed to increase thermal and acoustic insulation, once installed it acts as a second barrier to minimise cold draughts and prevent heat loss. Where security is a concern, secondary glazing provides high-security levels for domestic and commercial buildings. It is almost impossible to open from the exterior of the building. The durable aluminium frames can be supplied with locks and toughened glass designed to prevent forced entry.

How effective is secondary glazing?

Secondary glazing provides an effective solution to reduce heat loss and prevent noise from entering domestic and commercial properties. It can be installed with a speciality Low-E glass (thermal glass that is designed to reflect heat into the room) or an acoustic laminated glass that includes a PVB interlayer. This PVB interlayer is particularly effective at reducing low-frequency noise that is often emitted by cars, trains and planes.

80% Acoustic insulation with secondary glazing

Secondary glazing can help reduce noise entering your home by as much as 80% which is the equivalent of 54 decibels. We recommend that the secondary glazed system be installed up to 200mm away from your primary window for optimum acoustic insulation. If you have a shallow window reveal, we can provide a thicker glass specification that includes acoustic laminated glass.

65% Thermal insulation with secondary glazing

Over time, older window frames are subject to become warped and no longer provide an insulating seal, period buildings can lose around 20% of their heat via draughts. Low thermal insulation can lead to an increase in energy consumption and higher heating costs. Secondary glazing is designed to provide a second barrier to prevent cold draughts and will substantially reduce heat loss. For optimum thermal insulation, we often recommend that the secondary glazing system is installed as close to the primary window as possible and with a Low-E glass that is designed to reflect heat into the room.

Secondary Glazing Products

Secondary glazing is available in multiple styles and is designed to match your primary windows' size, shape, and function.

When specifying for secondary glazing, we would always advise that you match your primary window style; if you have traditional box sash windows, we recommend a vertical sliding secondary glazed system or a hinged system. Horizontal sliding secondary glazing is best suited for wide casement windows with multiple panes of glass. Matching the style of your primary windows ensures that the secondary glazing provides a slim, discreet and unobtrusive aesthetic.
