Double Glazing

Sometimes, the original glass can be re-used as one of the panes in the new unit. If you have any further questions or would like a quote please do not hesitate to contact us. From windows and doors to facades and conservatories, there are lots of uses for glass in the structure of a property. However, this might not be something you’ve ever really paid much mind to unless you are designing, building or refurbishing a property. The major reason for glazing doors or windows from the outside is there is a rebate that is part of the sash.

Additionally, laminated or thicker glass on the secondary pane can further enhance sound insulation. This makes it a popular choice for homeowners seeking to improve comfort without compromising the aesthetics or integrity of period features​. Secondary conservatory glazing offers multiple key features that enhance window performance, including significant sound insulation, improved energy efficiency, and condensation reduction.
The coating has hydrophilic properties which mean it attracts water over its entire surface, avoiding unsightly uneven water marks. This is made from a sheet of annealed glass reheated beyond its annealing point of around 1200 degrees Fahrenheit and then cooled slowly. Heat strengthened glass may be twice as strong as annealed glass, but may still need to be laminated for use in buildings. Tempering is the process by which annealed glass is heated in the same way as heat strengthened glass. The glass is cooled more rapidly which allows the internal portion of the glass to remain fluid for longer than the outer surfaces. This means that an equal amount of tensile and compressive stresses are formed across the glass which allows it to become in the order of four times as strong as annealed glass.

If external noise is a persistent issue in your home, secondary glazing is the most effective way to preserve and enhance your peace and quiet. If draughty windows are of bigger concern for your property, secondary glazing adds an extra layer of defence to protect your home from heat loss. The results are staggering, with reduced noise levels of up to 80% and a reduction in heat loss of up to 65%. Secondary Glazing involves adding another slim-line window to your existing windows.
We apply the sealant in a molten state so that it flexes if the unit does and keeps the unit airtight. Sunlight produces short wave infrared radiation – this is what warms objects in the sunshine. The short waves are absorbed by glass from the outside and the energy becomes re-radiated from the inside of the glass as long-wave infrared. Internal condensation happens when the seals on the sealed unit begin to fail and more moisture is drawn into the unit. The desiccant becomes saturated and can no longer hold moisture and as a result, condensation forms inside the unit. As the sound wave travels, dense objects absorb the energy which reduces the frequency of the waves as it passes through.

The Window Energy Ratings (WER) is a scale developed by the British Fenestration Ratings Council (BFRC) to measure the thermal performance of windows. The BFRC label indicates the rating of the window on a scale running from A+ (the most energy efficient) to G (the least efficient). The term 'glazing' refers to the glass component of building's façade or internal surfaces.

Float glass might sound fancy, but in fact it’s just the way most glass is made. Your choice of frame for your windows and the way they're sealed can only make so much difference to how much noise you hear from outside – and how much sound from indoors leaves your home. Together with placing the window in good repair a draughtproofed, slim double-glazed window with a thermal blind, shutters and curtains can easily out-perform many new windows. Slim profile double glazed panels can help raise overall window performance to a high level.
