Few Toronto neighbourhoods are as defined by their windows as Forest Hill. The Tudor Revival, Georgian, and Edwardian homes along Old Forest Hill Road, Warren Road, Vesta Drive, and Dunvegan were built in an era when the slim steel casement was the mark of a serious house — crisp black sightlines, leaded glass, and generous openings. A century on, those original steel windows are drafty and single-glazed, and the vinyl and aluminium replacements that followed never matched the proportions. Steel windows are how Forest Hill homeowners get the authentic look back — with modern thermal, acoustic, and security performance the originals could never offer.
Opulence Architectural Systems supplies and installs genuine European thermally broken steel windows for Forest Hill homes. As Canada's only authorized showroom uniting seven world-class fenestration brands, we carry the two finest steel systems in the world — Secco Sistemi from Italy and Forster from Switzerland — and specify the right one for each elevation, whether the brief is a faithful heritage restoration or a bold contemporary addition.

Why Forest Hill Homes Choose Steel
Steel is the strongest framing material available, with a strength-to-weight ratio no aluminium, wood, or vinyl can match. That strength is what lets a steel frame carry a large expanse of heavy triple-glazed glass on a sightline as narrow as 25–27mm — three to four times slimmer than a typical vinyl window. For a Forest Hill home, that means more daylight, cleaner divided-lite proportions, and a window that reads as architecture rather than product.
Forest Hill's conservation-minded streetscape rewards authenticity. Where a renovation is expected to respect the home's period character, a genuine steel casement is the correct detail — and modern thermally broken steel delivers it without the cold frames and single glazing of the originals. For new and contemporary builds in the neighbourhood, the same slim steel profile creates the minimalist, gallery-like glazing that defines modern luxury. See the full range on our Steel Windows Toronto page.
The Steel Systems We Install in Forest Hill
We specify the steel system to the architecture — the heritage brief, the glazing weight, and how the window has to perform through a Toronto winter. Our most-requested Forest Hill steel systems include:
Secco Sistemi OS2 75
The only steel window system offering every opening type — tilt-and-turn, pivot, bi-fold, lift-and-slide, and fixed — in a single 27mm profile series, available in steel, brass, stainless, and Corten. It is our reference choice when a Forest Hill project wants consistent slim sightlines across the whole house, from casements to a steel garden door.
Secco Sistemi EBE 85
A thermally enhanced steel system for the most demanding energy specifications — the choice when a Forest Hill renovation needs heritage sightlines and the warmth of a near-passive window on an exposed elevation.
Forster Presto 50
Swiss precision engineered for heritage restoration and, where required, fire-rated openings. Presto 50 matches original profile proportions closely, which makes it our go-to for faithfully restoring the steel casements of Forest Hill's Tudor and Georgian homes.
Steel also extends beyond windows — a matching Secco steel door or slim steel garden door completes the look. Browse the full Secco and Forster collections, or compare steel against our aluminium systems in the steel windows design guide.
Our Forest Hill Steel Window Process
Every project begins with a complimentary consultation at your Forest Hill property or in our North York showroom, where you can operate full-scale Secco and Forster steel systems side by side. We take precision measurements, match the profile to the home's period detail, and model the glazing package for the exposure — then provide transparent, line-item pricing. Custom manufacturing in Europe takes 8–14 weeks, after which our factory-trained crew handles careful removal of the originals, structural preparation, and installation with meticulous site protection — every steel window backed by both the manufacturer warranty and our own workmanship guarantee.
Steel Windows Forest Hill — FAQs
Do you install steel windows in Forest Hill?
+
Yes. Forest Hill is one of our most active Toronto neighbourhoods for steel windows — its Tudor Revival, Georgian, and Edwardian homes along Old Forest Hill Road, Warren Road, and Vesta Drive were originally built with slim steel casements, and our thermally broken Secco Sistemi and Forster systems restore that authentic look with modern performance. Our factory-trained crews serve Forest Hill from our North York showroom.
Are steel windows a good match for a Forest Hill heritage home?
+
They are the authentic choice. The slim steel casement is the window the neighbourhood’s Tudor and period homes were designed around, and our Forster Presto 50 and Secco OS2 75 systems match original profile proportions — sightlines as narrow as 25–27mm — while adding thermal breaks, triple glazing, and modern weather seals the originals never had. They satisfy the character many Forest Hill renovations are expected to preserve.
Are steel windows warm enough for a Toronto winter?
+
Yes. Modern steel windows are thermally broken — a polyamide barrier separates the inside and outside of the frame so cold cannot transfer through the steel. Paired with warm-edge triple glazing, Secco and Forster steel systems reach U-values comparable to premium aluminum while keeping the slimmest frames available, so a Forest Hill home stays comfortable and condensation-free through the coldest months.
How slim can the steel frames be?
+
Our Secco Sistemi OS2 75 achieves a visible face width of just 27mm, and Forster profiles are similarly minimal — three to four times slimmer than a typical vinyl or wood window. That is the defining advantage of steel: maximum glass, minimum frame, and crisp sightlines no other material can equal while still carrying large triple-glazed panels.
What does a steel window project cost in Forest Hill?
+
Genuine European thermally broken steel commands a premium over aluminum for its ultra-slim sightlines and heritage authenticity — generally in the range of $170–$280+ per square foot installed, depending on finish (steel, brass, stainless, or Corten), glazing, and configuration. Every Forest Hill project is quoted per opening after a free measurement; see our European windows cost guide for 2026 ranges by brand.
