Overview

Calculating aluminium sizes is essential as these are the overall manufacturing sizes that we will fabricate the products to finish. 

NOTE:  Reveal will add 40mm to the aluminium size.

NOTE: Reveal + Closer Trim will add 43mm to the aluminium size.

For more information regarding installation please see the EZ Windows Aluminium Window Installation Guide.

Calculate Actual Aluminium Window Size
Once you have your overall window size you can make the necessary deductions to get your actual aluminium window sizes.

NOTE: You will need to enter actual aluminium window sizes into the EZ Windows web portal…

If you only require reveals: With your overall finished window sizes, you need to subtract your reveal – 40mm to get your actual aluminium size.

If you require reveal & closer trim: With your overall finished window sizes, you need to subtract your reveal & closer trim – 43mm to get your actual aluminium size

What is a Reveal?

The timber reveal is the internal timber lining that surrounds the aluminium frame. You fix your windows to the stud through the reveal. Timber reveals come pre primed, are 20mm thick and come in various depths to accommodate all Constructions.

• 100mm (pine weatherboard/cladding)
• 110mm (Hardwood weatherboard/cladding)
• 135mm (Brick veneer)
• 160mm (Solid brick)

What is a Closer Trim?

If you need an inline reveal setup then you can select a closer trim. This trim closes the external 20mm rebate around the outside of the aluminium frame making your whole window the same height and width overall outside aluminium as inside over the reveal.

Commonly used in solid brick and brick veneer constructions, the closer trim makes it easy to install into brick constructions where the internal studwork and brickwork are basically in line – the same opening size
