3. Cost Breakdown of a Sunroom Addition
A. Structural Frame Costs
The material used for the sunroom’s frame impacts both aesthetics and longevity.
- Aluminum Frame – $3,000 – $10,000 (lightweight, durable, low maintenance)
- Vinyl Frame – $2,500 – $8,000 (good insulation, affordable, low maintenance)
- Wood Frame – $5,000 – $15,000 (natural look, strong but requires maintenance)
✅ Tip: Choosing a thermally broken aluminum or insulated vinyl frame helps improve energy efficiency.
B. Glass & Windows Costs
The type of glass you choose affects insulation, UV protection, and heating/cooling efficiency.
- Single-Pane Glass – $25 – $40 per square foot (basic, not energy-efficient)
- Double-Pane Glass – $40 – $75 per square foot (better insulation, standard for most sunrooms)
- Low-E Glass – $50 – $90 per square foot (reduces UV exposure, improves energy efficiency)
- Tempered Glass – $60 – $100 per square foot (safety glass, required for building codes)
✅ Tip: Double-pane Low-E glass is ideal for year-round sunrooms in Toronto.
C. Roofing Costs
The roofing material significantly impacts insulation and durability.
- Polycarbonate Roof Panels – $20 – $40 per square foot (lightweight, UV-resistant)
- Glass Roof – $40 – $90 per square foot (maximizes sunlight, expensive)
- Shingled Roof (Traditional Extension) – $30 – $70 per square foot (blends with home’s design, good insulation)
✅ Tip: A shingled roof is best if you want your sunroom to integrate seamlessly with your existing home.
D. Flooring Costs
Flooring options affect both comfort and maintenance needs.
- Vinyl Plank Flooring – $5 – $12 per square foot (water-resistant, affordable)
- Porcelain Tiles – $10 – $25 per square foot (durable, moisture-resistant)
- Hardwood Flooring – $15 – $35 per square foot (luxury feel, requires maintenance)
- Concrete Flooring – $8 – $20 per square foot (durable, can be stained or polished)
✅ Tip: Luxury vinyl plank (LVP) is a budget-friendly, durable flooring option for sunrooms.
E. HVAC & Electrical Costs
- Mini-Split HVAC System – $2,500 – $5,000 (heating & cooling solution for four-season sunrooms)
- Ceiling Fan Installation – $300 – $700 (improves air circulation)
