While double glazing has already resolved many of the problems associated with single glazing, it still has inherent problems when it comes to even temperature regulation in your home. Here is why triple glazing is the answer to your draft problem and cold spot problems.
There are many causes for drafts occurring in your home. Assuming all windows and doors are properly closed, here is a list of the most common other causes of drafts:
roken or damaged seals or insulation between the glass and the frame
Wear and tear around the frame, especially outside
Broken or damaged hinges, catches or locks
Thermal insulation dictates that not only windows and doors, but also walls and ceilings be thoroughly insulated to prevent heat transference.
Different materials have different heat loss resistance rates (R-values). The higher the R-value, the better resistance the material has to thermal transference.
An insulated brick wall has an R-value of more than 4 and insulated roofing could be have a value in excess of 6. Single glazing has an R-value of less than 1 and double glazing has a value of 3. Both of these glazing options have a lower resistance to thermal heat loss than the surrounding building elements, causing the air around the windows to be cooler than in the rest of the home.
Triple glazing has an R-value of 5 and so has the ability to maintain an even temperature inside the home, without causing cold spots.
The most effective solution is to install triple glazing throughout your home. The complete insulation of each window unit will ensure that your home has no cold spots or drafts. This does however require that the other building elements in your home (roof, exterior walls and doors) also have efficient insulation.
If new glazing is not an option, you can also try these temporary solutions:
Use a DIY window kit to fix the broken seals around windows
Maintain all hinges and catches, and replace any broken ones
Change the layout of your rooms to ensure that exposure to the cold areas are minimized.
Install interlined curtains to block cold air from coming through compromised windows – this does however end up blocking sunlight as well.
It is important to note that it is highly unlikely that windows installed after 2002 will have draft problems. Since April 2002, legislation requires any double or triple glazing installed to comply with strict building regulations.
To determine the age of your glazing, look at the FENSA certificate that you would have received after installation or with the purchase of your home. It could also be stamped on the metal seal on the window unit itself.
The most efficient way to maintain a constant temperature in your home is to ensure that your walls and roofs are sufficiently insulated, and to replace your inefficient, older windows with triple glazing.
