Our sunroom projects include R-20+ wall insulation, R-40+ roof insulation, triple-pane or double-glazed windows with low-E coatings, thermal breaks preventing heat transfer, and integrated HVAC systems. We orient structures maximizing solar gain during winter months while incorporating shading strategies preventing summer overheating. The result: beautiful four-season room spaces usable 365 days annually.
Conservatory & Solarium Design
Traditional conservatory construction combines classic architectural elegance with modern performance. Our solarium builders create stunning glass structures featuring ornate details, decorative glazing bars, ridge cresting, and architectural finials recalling Victorian-era greenhouses while incorporating contemporary Fenster Building high-performance glazing and energy-efficient systems.
Solarium designs maximize glass area for abundant natural light and panoramic views. Floor-to-ceiling glass, glass roof systems, and minimal framing create virtually transparent spaces blurring boundaries between indoors and outdoors. Our sunroom team engineers these structures managing snow loads, wind loads, and thermal expansion ensuring safety and durability in Canadian climate conditions.

Successful four-season room construction in Toronto's climate demands sophisticated energy management strategies. Our sunroom specialists incorporate high-performance glazing from Canadian manufacturers like Fenster Building, featuring triple-pane construction, argon gas fills, low-E coatings optimizing solar heat gain, and warm-edge spacers reducing thermal transfer. These advanced windows maintain comfortable interior temperatures while minimizing heating and cooling costs.
Beyond glazing, proper insulation represents critical sunroom construction components. We install R-24 wall insulation and R-50 roof insulation using products from Owens Corning Canada, ensuring thermal performance exceeding Ontario Building Code requirements. Thermal breaks between metal components prevent heat transfer, air sealing eliminates drafts, and strategic ventilation prevents condensation. Our glass enclosure designs deliver year-round comfort with minimal energy consumption.
Our Sunroom Construction Process
From design through completion, our glass enclosure experts deliver exceptional results
1. Design & Engineering
Every successful sunroom project begins with comprehensive design addressing aesthetics, functionality, solar orientation, views, and structural requirements. Our team evaluates your home's architecture, yard configuration, sun exposure patterns, prevailing winds, and existing connections determining optimal glass enclosure placement and configuration. We understand how Toronto's varying sun angles affect comfort throughout seasons.
Design development transforms assessment findings into detailed plans for your four-season room or conservatory. Our architects create structural drawings showing foundation requirements, framing systems, glazing details, roof configurations, and connections to existing homes. We select glazing systems optimizing energy performance—triple-pane windows for north-facing exposures, different glazing for south-facing solariums maximizing beneficial winter sun gain while controlling summer heat.
Structural engineering ensures sunroom construction withstands Canadian weather conditions. We calculate snow loads, wind loads, and structural connections designing robust systems meeting or exceeding Ontario Building Code requirements. Our team prepares complete permit applications including architectural drawings, engineering calculations, and compliance documentation. We've never had a glass enclosure project fail permitting or inspection.
2. Foundation & Structure
Proper foundation work provides essential support for sunroom structures. Our team excavates carefully, installs footings sized by engineering calculations, pours foundation walls or slab-on-grade systems appropriate to project requirements and soil conditions, and ensures proper drainage and waterproofing protecting your investment. Foundation work typically requires 1-2 weeks depending on weather and complexity.
Structural framing creates the skeleton of your glass enclosure. We install pressure-treated plates, wall framing supporting glazing systems, roof structures managing snow loads, and connections integrating sunroom seamlessly with existing homes. For conservatory projects, we install structural aluminum components, glazing bars, and ridge systems creating elegant, durable glass structures. Our solarium builders use premium materials ensuring longevity.
Connections between new four-season room and existing homes require particular attention. We install proper structural ties, waterproofing membranes preventing water infiltration, and thermal breaks preventing heat transfer. Door and window openings create convenient, attractive transitions between homes and sunrooms. Our team ensures structural integrity and beautiful integration matching existing architecture.
3. Glazing & Systems Installation
Glazing installation represents the most distinctive aspect of sunroom construction. Our team installs high-performance windows and glass systems precisely, ensuring proper sealing, weatherproofing, and operation. We use products from Fenster Building, featuring triple-glazed units with superior thermal performance. For solarium projects, we install glass roof systems managing snow loads and water shedding effectively.
Mechanical installations transform enclosed structures into comfortable living spaces. HVAC systems extend from existing homes or install independent equipment providing heating and air conditioning. Our four-season room projects include radiant floor heating (exceptional for glass spaces), ducted systems, or mini-split units providing zoned temperature control. Electrical installations include ample lighting, outlets, and controls managing ventilation and shades.
Insulation installation dramatically affects sunroom comfort and energy efficiency. We upgrade wall insulation to R-24 or better, install R-50 roof insulation using products from Owens Corning Canada, and ensure comprehensive air sealing. Proper insulation creates stable temperatures preventing condensation and reducing energy costs. Our glass enclosure specialists exceed code requirements delivering superior performance.
4. Finishing & Integration
Interior finishing completes your sunroom transformation. Drywall installation on insulated surfaces creates smooth walls ready for painting. Our team paints using premium products, often selecting light colors maximizing natural light reflection. Trim work including baseboards, window casings, and ceiling details provides finished complementing glass expanses. Many clients select ceramic or porcelain tile flooring reflecting sunlight and providing durability.
Flooring selection significantly affects four-season room aesthetics and performance. We recommend durable materials like ceramic tile, porcelain tile, or polished concrete absorbing solar heat and providing thermal mass regulating temperature fluctuations. Hardwood or laminate flooring also works beautifully, adding warmth underfoot. Our team helps clients select materials balancing beauty, durability, and compatibility with solar gain.
Exterior finishing ensures your glass enclosure enhances curb appeal. We match existing siding materials where sunrooms connect to homes, install proper roofing and flashing preventing water infiltration, and complete exterior trim details creating polished appearances. For conservatory projects, decorative elements like finials, cresting, and ornamental glazing bars provide authentic period styling. Final inspections verify code compliance.
