What exactly is double glazing and why do we need it most people on a budget ask? Well double glazing is the name for windows that are made up of two panes of glass or other transparent material with an air space between them. This dead air space acts as an excellent insulator in many ways, from noise reduction to air transference. It will keep the home cool during summer and warm during winter by keeping the temperature even or as specified by your heating control. These panes are usually either 28 or 24mm in width. All much larger windows are available and are made to measure.
UPVC is the most common type of double glazing unit and stands for Un-plasticised Poly Vinyl Chloride and is very resilient. This is used because it does not rot or decompose; it is weather resistant and retains its shape in moderate temperatures. It does not flake and will not need painting. It can also be reshaped in very high temperatures so it is recyclable into the same or other objects. Recycled double glazed window and doors units though are dull in appearance and are susceptible to dirt and easily discolour. Once this happens it will not be able to be cleaned back to brilliant white and will stay looking worn out.
All double glazed windows are not the same and the quality is reflected in the price. This is because of new advances every year and perfecting technology within the industry. Also new glass coatings are being created all the time to something now that hardly needs cleaning. This type of low maintenance glass is ideal for high windows and conservatory roofs.
There is also a difference in double glazing units depending on what you require. If noise reduction is needed because of living near a busy road, railway or construction then a compromise is needed if you would prefer to reduce heat loss. Some expensive units offer both but secondary double glazing is ideal for both these problems as the air space between the panes can be made larger. The best distance between the two panes of glass is 4mm.
Also composite double glazed doors will add more security than just replacing the windows. Conservatories are an added space and between your building and added rooms are internal doors that can also be locked. Made from hardwood or UPVC, folding or sliding doors are increasingly used to replace traditional internal, patio or traditional French doors. The doors that also link a conservatory to your home can have flush fitting thresholds at floor level and this eliminates the conventional 'step over' and can be sunk into brickwork.
