First, let’s check your window
Before ordering your ecoGlaze ON-SASH READY-TO-GO KIT, we just need to make sure this system will fit your window or door.
When your window or door is fully closed, measure the depth of the timber frame.
You will need a minimum of 26 mm for ecoGlaze On-Sash to fit. Measure all sides using the below images as reference.
If you have less than 26 mm of exposed timber, your window may suit a different ecoGlaze system.
If you are not sure, please email us a few clear photos and we’ll help you work it out.
