Reynaers Aluminium | Windows
Reynaers SlimLine 38 profile for Ontario homes.
Slender steel-look aluminium window system with high insulation, contemporary styling and minimalistic design variants. ECOWIN uses this page to explain where the profile fits, what needs to be checked and how it works with warm insulated glass packages.

Slim steel-look windows
What SlimLine 38 is used for.
SlimLine 38 is reviewed when a project needs Reynaers aluminium windows with European operation, clean sightlines and a glass package selected for Canadian comfort. ECOWIN compares this profile with other Reynaers window systems so the client does not overpay for unnecessary depth or under-spec a demanding opening.
For every Reynaers profile, the final specification depends on the opening size, colour, glass unit, wind exposure, threshold, drainage, hardware and installation conditions. ECOWIN reviews these items before preparing the quote so the client sees the system that actually matches the project.
ECOWIN planning checklist
What must be confirmed before ordering.
- Confirm fixed, tilt-and-turn, casement, balcony door or combination window geometry.
- Select warm double or triple insulated glass by opening size, orientation and comfort target.
- Review frame depth, visible sightline, colour, handles, screens and drainage before ordering.
- Check structural limits, wind exposure and installation details for Ontario weather.
Warm glass package
Profile plus glass, not profile alone.
Premium Reynaers systems should be planned with the right insulated glass unit, Low-E coating, gas fill, warm edge spacer, safety glass where needed and installation detailing. This is especially important for large openings, doors, sliding panels and exposed elevations.
