The Benefits of Double Glazing
The Facts:
- Security and safety are maximised with double glazing
- Energy saving windows means lower bills
- Secondary glazing is suitable for conservation areas
There is no doubt that double glazing has many benefits for today’s householder and even those who live in conservation areas or in listed buildings where double glazing is forbidden can enjoy similar advantages by installing secondary glazing.
One of the prime reasons for choosing double glazing is the enhanced security it offers. The window frames and locking systems on such units make it far harder for intruders to gain entry – an im portant consideration in these days of increased crime rates.
Safety, too, is an important factor. Traditional single pane windows are made from one sheet of regular glass. If hit it is liable to shatter into long, sharp and dangerous shards of glass. This is not the case with double glazing which is much safer if it breaks – a significant benefit, particularly in homes with young children.
The safety of double glazing can be further increased with the use of security, toughened or shatterproof glass. In fact, regulations stipulate the use of such glass in so-called ‘critical locations’. These include low level glazing in doors, windows, partitions and walls. The legal requirements apply to every domestic glazing installation whether it is a new build, a replacement or a refurbishment.
As heating bills soar, energy conservation is also a major reason for choosing double glazing. Studies have shown that modern homes can lose as much as 25% of their heat through the windows. This heat loss can be significantly reduced through the installation of low-emissivity (low E) glass. This allows heat and light from the sun to enter the
building through the glass but stops heat leaving. As well as bringing a reduction in energy bills this also helps maintain a higher internal temperature. With so many consumers looking for a greener option this is a great way of thinking of the environment and saving money on the heating bills.
One argument often raised against double glazing is that it can transform the appearance of a building. This is true but it doesn’t have to be to its detriment. Good contractors are keen for the projects in which they are involved to be seen to enhance the properties so they will be eager to work with you to ensure that your choice complements the architecture of your property.
It’s important to remember that double glazing is usually prohibited in conservation areas and also for listed buildings. However, subject to local authority approval, secondary glazing is a satisfactory substitute.
Indeed, even in standard homes, internal secondary double glazing can be a cost-effective solution to improving thermal and noise insulation as long as the main window is essentially sound and in good condition.
Secondary glazing comprises slim, unobtrusive white-enamelled aluminium profiles, usually with single glazing. However, secondary double glazing can also be is also available for specialist applications. These units follow the design of the main window and are installed inside it.
Secondary glazing products include:
- Vertical sliders for sash windows, with a tilting and removable sash facility to make cleaning easier
- Horizontal sliders with removable sashes for 'picture' type casement windows
- Hinged units for narrow casements, doors and French doors or windows; sashes can be removed
- Lift-out units for use when access is rarely required to the main window
- Fixed units, normally used to insulate glass panels within doors
Triple glazing involves the addition of a third pane of glass into the unit. The result is even more effective sound insulation so it is an excellent addition to homes in built-up areas, near busy roads or close to anything that causes significant sound pollution.
Not surprisingly, triple glazing also offers increased energy savings.
So, whatever your requirements, whatever type of home you live in, there is a double glazing solution to meet your needs. |
