76 mm window systems / PVC-U window and door systems
Kömmerling 76 Systems for Ontario homes.
A versatile 76 mm Kömmerling platform for renovations and new builds where slim sight lines and balanced performance are important.

Profile overview
What this profile is for.
Kömmerling 76 Systems cover double-seal and centre-seal versions, giving ECOWIN flexibility for different openings and renovation conditions. The 76 mm depth is practical when a home needs better comfort without overbuilding the wall detail.
The profile family is especially useful where the existing frame depth, interior trim or exterior cladding limits how much profile can be introduced. It still keeps the European PVC-U advantages: welded corners, multi-chamber geometry and modern glazing options.
For Ontario homes, ECOWIN can pair this platform with warmer glass packages and spacer technology to improve winter comfort while keeping the appearance clean and not overly bulky.
Key technical points
- 76 mm construction depth
- Double-seal and centre-seal options
- Slim sight line planning
- Suitable for renovations and new construction
- Compatible with modern functional glazing
Glass package
A two-chamber insulating glass unit can be selected for stronger winter performance. Warm edge spacers help reduce thermal bridging at the glass edge and support better indoor surface temperatures.
Where ECOWIN would use it
A strong middle option for replacement windows, townhomes, additions and projects where the 88 mm family may be more depth than the opening needs.

Plan this profile with ECOWIN.
We match the profile, two-chamber glass unit, warm spacer and installation detail to the opening instead of treating every window the same.
