The Technology Behind Energy Efficient WindowsBetter Energy Efficient Glazing!
What makes our glass better than normal glass?
The interior panel uses a new generation, magnetron coated Low Emissivity glass as opposed to standard Low ‘E’ glass, which actually reflects heat back into the room.
Old fashioned sealed units can often have a brown or yellow tint to them whereas our new Low 'E' glass is crystal clear. For your outer pane, we replace standard clear glass with a specially formulated, ultra clear ‘Low Iron Glass’.
Standard glass contains minerals and metals that reduce clarity and give a green tint.
Using a special process to remove these deposits, the tint is also removed, and we are left with a ‘white’glass.
This white glass allows more heat and light to pass into your home. The combination of these two energy efficient glasses will help to reduce your heating bills throughout the year.
Frames That Fit The Bill
There’s more to making an energy efficient window than clever glass technology, there’s also intelligent technology developed for the aluminium spacer running around the edge of the glass to separate the panes to form the insulating cavity of the unit.
The aluminium that is conventionally used in this spacer bar is in an excellent conductor of heat and in a conventional window this point is allowed to draw heat away from the room into the outside world.
We don’t use a conventional aluminium spacer bar; rather than a conventional metal spacer frame, our sealed units use a modern composite polymer material which is up to 950 times less conductive than aluminium. Because the material doesn’t conduct heat away from the house through the window, the heat loss at the edge of the glass is hugely reduced.
Argon Filled Windows
Many people believe that the inner ‘cavity’ of a sealed unit is a vacuum; it isn’t, it’s just filled with dry air. Air a reasonable insulator, but it’s not as good as Argon gas; by replacing the air in the window with argon, an extra barrier to heat loss is created. But don’t just take our word for it.
The transmission of heat is easily measured and quantified in what’s called a ‘U-Value’ attributed to every window.
The lower the U-Value, the lower the rate of heat transfer, and the better
