Double glazed aluminium windows
Double glazed aluminium windows give you slim, modern frames with two panes of glass. Frames with a thermal break stop heat escaping through the metal.
A common sign
“We want better windows, but we love the slim look of aluminium.”
About double glazed aluminium windows
Slim frames that keep the warmth in.
Standard aluminium frames let a lot of heat through. A thermally broken frame has an insulating strip inside it that cuts that heat flow. Paired with double glazing, it makes a big difference to how warm a window feels.
Aluminium is strong, so frames can be slimmer and openings larger. That makes it a common choice for big doors, wide windows and homes where the original look needs to be kept.

Keeping a slim, modern look
Ask whether the frames are thermally broken. Double glazing in a standard aluminium frame performs well below the same glass in a thermally broken one.

Other upgrades in this category.
Single glazing is where a great deal of your heating escapes. These trades retrofit the windows you already have, or replace them properly.

uPVC double glazed windows
The warmest frame of the common options, and the quietest. A full replacement rather than a retrofit.

Triple glazed windows
Three panes for the coldest rooms and the noisiest roads. Rare in Australia and worth asking who has actually fitted it.

Secondary glazing
A second pane fitted inside the window you already have. Far cheaper than replacement, and it works on heritage frames.

Retrofit double glazing
Double glazed glass fitted into the frames you already have. The frames stay and only the glass changes.

Window and door replacement
Not every glazing job is double glazing. Rotten frames, jammed sashes and doors that never sealed properly.
