Fiberglass-frame, triple-glazed windows for a high-performance commercial retrofit in Toronto.
The Ontario Association of Architects Headquarters is a recognized Toronto building known as “Wings Over Don Mills.” When the building required a major retrofit, the project team needed window systems that could support a stronger building envelope, improved energy performance, and the long-term goals of a sustainability-focused institutional project.
Inline Fiberglass supplied fiberglass-frame, triple-glazed windows as part of the envelope upgrade, helping the project team improve thermal performance while maintaining the clean architectural character of the building.

Project Snapshot
A Retrofit Built Around Performance
The OAA Headquarters retrofit was more than a cosmetic update. The project was planned to refresh the interior, improve energy performance, and support the building’s alignment with the 2030 Challenge, a building-sector goal focused on reducing greenhouse gas emissions in major renovations and new construction.
The envelope upgrade included added insulation, curtainwall retrofits, and new Inline Fiberglass window systems. For a project like this, the windows were not just a finish selection. They were part of the building performance strategy.
Project Snapshot
Project: Ontario Association of Architects Retrofit
Location: 111 Moatfield Drive, Toronto, ON
Building Type: Institutional / Commercial Retrofit
Project Type: Deep Energy Retrofit
Window Type: Fiberglass-frame, triple-glazed
Architect: David Fujiwara
Contractor: MJ Dixon Construction Ltd.
The Challenge: Upgrade a Recognized Building Without Compromising Performance
The OAA Headquarters was originally built in 1992. Over time, the building required a significant retrofit to improve comfort, update the interior, and reduce operating energy use.
For the project team, the window package had to support several priorities at once:
-
Improve the performance of the building envelope. -
Help reduce heat loss through the window openings. -
Support triple-glazed performance requirements. -
Work within a commercial retrofit context. -
Respect the architectural identity of an institutional building. -
Provide long-term durability for a high-profile organization.
In a deep energy retrofit, window selection carries real weight. Poor frame performance, air leakage, or weak thermal detailing can undermine the rest of the envelope strategy.
The Solution: Fiberglass-Frame, Triple-Glazed Windows by Inline Fiberglass
Inline Fiberglass supplied new fiberglass-frame, triple-glazed windows for the OAA Headquarters retrofit.
Fiberglass was a strong fit for this type of project because it supports several retrofit priorities at once: strength, low conductivity, dimensional stability, and long-term resistance to corrosion. For commercial and institutional buildings, those advantages can help support envelope performance while reducing the risk of premature material wear.
Triple glazing added another layer of performance, helping the project team improve thermal comfort and reduce energy loss through the window system.
Why Inline Fiberglass Made Sense for This Retrofit
For the OAA Headquarters, Inline’s fiberglass-frame window systems helped support:
Better Thermal Performance
Supports improved energy efficiency by helping reduce heat transfer through the building envelope.
Reduced Heat Transfer
Fiberglass frames are less conductive than many traditional frame materials used in commercial buildings.
Long-Term Frame Stability
Helps maintain window alignment and performance through changing temperatures and seasons.
Triple-Glazing Compatibility
Supports advanced glass packages commonly used in high-performance retrofit projects.
Clean Architectural Appearance
Slim, durable fiberglass frames complement contemporary commercial and institutional designs.
Durable Envelope Strategy
Contributes to a resilient window system designed for long-term building performance.

Triple-Glazed Fiberglass Window Systems
The OAA project used Inline Fiberglass window systems as part of a broader envelope upgrade. The live project page references fiberglass-frame, triple-glazed windows and notes Inline’s Series 3000 windows as Passive House International certified.
For architects, builders, and commercial project teams, this is the real value of a project like OAA: it shows how fiberglass windows can be used in serious retrofit work where performance, appearance, and long-term durability all matter.

Questions About The Ontario Association of Architects Project
Find clear answers to common questions about the Ontario Association of Architects project case study
What type of project was the Ontario Association of Architects Headquarters retrofit?
The OAA Headquarters project was a commercial and institutional retrofit in Toronto. The project included building envelope upgrades intended to improve energy performance and support broader greenhouse gas reduction goals.
What window systems did Inline Fiberglass provide?
Inline Fiberglass supplied fiberglass-frame, triple-glazed windows for the retrofit. The live project page also references Inline’s Series 3000 windows as Passive House International certified.
Why are fiberglass windows useful for commercial retrofits?
Fiberglass frames are strong, stable, and less conductive than many traditional frame materials. For commercial retrofits, that can help improve thermal performance, support triple glazing, and contribute to a more durable envelope upgrade.
Can Inline support similar commercial or institutional projects?
Yes. Inline Fiberglass supports commercial, institutional, high-performance, and residential projects with fiberglass window and door systems. Project teams can request product guidance, technical documents, and quote support.
Can architects request product specs or drawings?
Yes. Architects, specifiers, builders, and commercial project teams can request product specs and technical support from Inline before selecting the right window system.
