Secondary Glazing Windows

This is why the edge of the glazed unit has always been the weak spot where it's the coldest. Warm edge spacer bars are blended from stainless steel and polypropylene which has a low thermal conduction rate and this reduces heat loss at the edge of the sealed unit. Our integrated system of CosyGlazing secondary glazing for sash windows allows you to slide the sashes open as usual while the CosyGlazing remains in place. As part of the fitting service, our sash window craftsmen reengineer the window, remove excess paint, release stiff sashes, replace chords and pulleys, balance weights and fit new beading with a concealed brush strip.

While double glazing offers significant insulation and energy efficiency benefits, it’s not the only option available to homeowners looking to enhance their property’s thermal performance. For those considering an investment in window upgrades, exploring all options can ensure you choose the most cost effective, suitable solution. CosyGlazing is Mitchell & Dickinson’s award-winning secondary glazing product, designed specifically for period and listed buildings. This unique insulating layer, made from plexiglass, provides warmth, comfort and an unobtrusive look.

Secondary glazing, although cheaper, is generally not as effective at keeping your home warm. It also doesn’t prevent condensation from building up nor add to your property’s security. Whereas in the past windows were generally single glazed consisting of just a single layer of glass, today there are many different options for glazing. Yes, secondary glazing can significantly improve noise reduction in a home. By adding a second pane of glass to existing windows, secondary glazing creates an extra barrier that can effectively block external noise. A gap of around 100–150 mm between panes is optimal for soundproofing, as it can dampen a wider range of sound frequencies.

Secondary glazing involves the precision installation of a slimline glazed unit inside your existing windows. Barely noticeable unless you’re trying to look for it, our latest product range boasts ultra-slim sightlines for a truly unobstructed view of the world beyond the window. A near endless array of RAL colours is available to match any existing window style. We all want quality products at the best prices, and you deserve the best double glazed windows for your home. So, if you find cheaper like-for-like uPVC windows with another company within 7 days, we’ll match the price. • Triple glazing has a deeper frame - The average depth of a double glazing unit is 28mm, whereas triple glazing can be as deep as 36mm.
First of all, you don’t need to replace your existing window pane to add secondary glazing yourself. This saves the cost you would incur when adding a double glazed glass window. From the 1980s onwards, double glazing became standard for new UK homes. Although only about 8% of UK homes featured double glazing in the 70s, the concept quickly took off and now over 85% of homes in the UK are fitted with double-glazed windows. Window specialists began using a ‘second window’ system in the mid-60s, which involved removing rotting timber windows and replacing the original window with a second layer of glass.

This causes any unstable nickel sulfide inclusions (imperfections that may cause spontaneous breakage of the pane) to expand disproportionately to the glass, making the glass break. This is named after the modern process used to create large, thin, flat panels from molten glass which is floated onto a pool of molten metal such as tin. This process produces a very smooth sheet of glass with a highly consistent thickness. Secondary glazing is particularly suitable for use in conservation areas and listed buildings and will retain the original external appearance of your property. Available in uPVC, wood or aluminium, all with a range of colours and options.
Huge range of rafter supported or self supporting glazing bars for both glass or polycarbonate sheet. Draughtproofing is a complementary measure which can be used in conjunction with secondary glazing. Where appropriate we support, in principle, the use of sympathetic secondary glazing where it can be demonstrated that there is no detrimental impact on the special architectural or historic interest of the building. When combined with timber shutters and heavy curtains the energy saved in cold weather can be as good as high-performance modern windows. The simplest systems are single pane panels which can be secured with magnetic tape, making them easy and quick to fit and reducing ‘retrofitting’ work to a minimum. This exclusive event for the window, door and conservatory industry brings together business owners, directors and senior management from across the entire industry for a packed one-day summit.
Period properties tend to have unusually shaped windows that are often not level and, as a result, a DIY solution can be tricky to install. Your ironmongery and catches are modified to work with the CosyGlazing system to provide maximum efficiency. With our CosyGlazing secondary glazing in place, you will feel the difference in warmth and comfort of your home immediately. Employing specialists to fit your secondary glazing ensures a professional installation, which is guaranteed, and saves you the stress of doing it yourself. Double glazing minimises heat loss thanks to the gas insulation in the sealed unit and the two glass panels.
