Suppose your home doesn’t already benefit from double glazing in Luton. In that case, you’ll undoubtedly be intrigued after learning how the double glazing process can help reduce your energy bill by saving a quarter of the heated air lost through poorly insulated windows and doors. So what are the methods within the double glazing system that function to reduce heat loss?
Conduction and heat transference is the key
Double glazing units in uPVC windows are a relatively uncomplicated innovation. Instead of a single pane of glass, two panes with a spacer in between – which we’ll return to later – are bonded together using an industry-standard polysulphide sealant with excellent moisture resistance and sealed with edging tape. The vacuum created between the two pieces of glass is then filled with argon.
Argon is an inert gas with very low heat conductivity, enabling the double glazing process to slow the transference and loss of heat from your home. With a traditional single glazed window, the heat loss would occur quickly from the inner to the outer pane, ensuring that any warmth you’re generating in your home is lost rapidly.
It’s all about creating space for the molecules
As explained above, heat is soon lost through single glazing. The reason is that the molecules in a single pane are firmly grouped will have little room to move. When the molecules interact with heat, it creates kinetic energy, which forces them to move faster and transfer that heat quickly from one to another and ultimately from your house to the outside.
Now we introduce the spacer bar that was mentioned earlier. Typically made of aluminium and some other metals, the spacer bar does what its name suggests and provides a space between the two panes of glass in double glazing in Luton. The gap created is pivotal to slowing the transference of heat as it allows the molecules within the two panes to be more sparsely distributed to prevent quick heat transference. The inert argon that fills the gap helps delay and reduces heat loss further.
Now you comprehend how the glass, spacer bar, argon and the heated molecules all interact within a double glazing unit; you should also understand that double glazing doesn’t necessarily eliminate heat loss but slows the process, so heat is lost more gradually. Minimising and slowing heat loss allows you to heat your home far more efficiently and retain the heat, which over time will help to reduce the cost of your energy bills significantly. If you live in icy-cold areas, then using a larger sized spacer bar, approximately 16mm can help to increase the insulating properties of double glazing. Triple glazing is also an option if your house frequently encounters sub-zero temperatures. Similarly, double glazing in Luton helps prevent rooms from overheating in the summer. The exact process operates to stop the convection of heat from outside into the interior of your home.
