Three-Season vs Four-Season Sunrooms: What Fits Your Home

Three-Season Sunrooms

Three-season sunrooms extend your living space for spring, summer, and fall without the cost of full HVAC. They feel airy and bright with abundant windows or screens and typically use less insulation. For many families, this is a great way to turn a deck or patio into a more flexible retreat.

• Pros: Lower cost, lighter structure, fresh airflow, quick build timelines
• Considerations: Limited winter use, more temperature swings

Four-Season Sunrooms

Four-season builds are designed for year-round comfort. These rooms use insulated framing, advanced glazing, thermal breaks, and integrated heating and cooling. When built with the right glass and HVAC package, they feel like a natural extension of your home no matter the forecast.

• Pros: Year-round use, better energy performance, higher resale value
• Considerations: Higher upfront cost, mechanical planning required

Not sure which route is best? J Kruzan will evaluate your site, budget, and goals, then help you choose the right path. Our sunroom construction services include both three-season and four-season designs, each tailored to Southeast Wisconsin’s weather and your comfort expectations.

Glass and Window Systems That Work in Our Climate

Great sunrooms start with the right glazing strategy. The goal is to maximize views and natural light while controlling heat loss in winter and heat gain in summer. J Kruzan offers custom glass packages that meet energy targets and fit your style.

• Low-E coatings: High-performance coatings reduce heat loss and reflect solar heat while keeping your yard and sky view crystal clear.
• Double or triple glazing: Double-pane glass is often ideal for sunrooms. Triple-pane can offer added comfort for four-season rooms on cold lakefront sites.
• Argon or krypton fills: Inert gas between panes improves insulation without changing the appearance of your windows.
• Thermally broken frames: Aluminum-clad or fiberglass frames with thermal breaks reduce condensation and improve comfort.
• Safety glass: Tempered or laminated glass is used in doors and larger panels for safety and code compliance.
• UV protection: Optional coatings help protect floors, rugs, and furniture from fading while preserving brightness.
• Ventilation windows: Operable units and screen systems provide airflow on mild days without inviting bugs inside.

We also help you choose the right window configuration. Full-height fixed panels deliver a stunning view, while casements or awnings add fresh air. Transoms bring in beautiful light under higher rooflines. With J Kruzan, your glass plan is tailored to the sun path and wind patterns on your property.

Roof Options: Light, Strength, and Snow Performance

Your sunroom roof shapes the look and performance of the space. We design roofs to handle local snow loads while keeping the room bright and comfortable.

• Insulated solid roofs: Shingle or metal roofs with robust insulation for four-season comfort and strong structural performance.
• Partial glass roofs: Limited glass sections add drama without excess heat gain or snow buildup concerns.
• Structural upgrades: Engineered beams, proper pitch, ice and water barriers, and careful flashing protect the room and your existing home.

HVAC and Comfort Control Integration

Heating and cooling transform a bright space into a true living room. J Kruzan plans HVAC from day one so the room feels even and quiet. We coordinate with inspectors to ensure code compliance and efficiency.

• Ductless mini-split heat pumps: Excellent performance in our climate with whisper-quiet operation and precise control.
• Careful duct extensions: Where practical, we may extend existing systems with proper sizing and zoning.
• Radiant floor heat: Warm floors under tile or luxury vinyl improve comfort on cold mornings.
• Ceiling fans and air circulation: Fans help equalize temperatures and support energy savings.
• Dehumidification: Optional moisture control for homes near lakes or shaded sites.
• Smart thermostats: Scheduling and remote control help trim energy use while keeping the room ready when you are.

Our team explains pros and cons for each option based on your home’s layout, electrical capacity, and use patterns. The result is a space you love in January and July.

Snow Load, Structure, and Foundations You Can Trust

In SE Wisconsin, a sunroom must stand strong under snow and freeze-thaw cycles. J Kruzan builds with stout framing, reliable roof assemblies, and foundations that protect your investment for decades.

• Snow-load design: We engineer framing and roof systems to meet or exceed local requirements. That includes joist sizing, ridge and beam selection, and proper roof pitch for our winters.
• Weatherproofing details: We use ice and water shields, flashing at every transition, sealed penetrations, and continuous air barriers to fight wind-driven snow and rain.
• Foundations for our soil: Depending on site conditions, we recommend insulated concrete slabs, frost-protected footings, or helical piers. Footings are set below local frost depth to prevent movement.
• Quality materials: Rot-resistant framing where needed, treated sill plates, and moisture-aware assemblies help keep your sunroom dry and durable.

We do not cut corners on structure. With J Kruzan, you get a sunroom that looks light and open but hides the strength needed for our climate.

Permits, Inspections, and HOA Approvals

Each community has its own process. Our sunroom construction services include permit drawings, energy documentation where required, and coordination with inspectors. We also assist with HOA applications to streamline approval. J Kruzan maintains open communication with municipalities across Walworth, Kenosha, and Racine counties to keep your project moving.

Electrical, Lighting, and Smart Features

Beautiful lighting and thoughtful electrical planning turn a good sunroom into your favorite room. We design lighting layers, outlets, and controls that feel natural from the first night you move in.

• Ambient lighting: Recessed fixtures or slim-profile lights for even illumination.
• Accent lighting: Wall sconces and under-shelf lights highlight art and plants.
• Task lighting: Reading lamps and pendants for cozy corners or breakfast tables.
• Code-compliant outlets: GFCI protection where needed and enough receptacles for real life.
• Dedicated circuits: Support for HVAC, floor heat, or future features.
• Smart shades and controls: Motorized shades, Wi-Fi dimmers, and scenes that set the mood.

Flooring and Finishes Built for Sunrooms

Finishes must handle sunlight, foot traffic, and temperature swings. J Kruzan helps you select materials that look great and last.

• Flooring: Porcelain tile, luxury vinyl plank, and engineered wood are top choices for durability and easy cleaning.
• Ceilings: Painted drywall, tongue-and-groove pine, or beadboard for a cozy cottage look.
• Walls: Moisture-resistant drywall or accent walls in wood or stone for texture.
• Trim and built-ins: Custom benches, window seats, and shelving add storage and charm.
• Color strategy: Lighter tones bounce natural light while deeper accents frame the view.

Our Sunroom Construction Process

1. Discovery Call: Share goals, timeline, and location. We discuss whether a three-season or four-season approach fits your plans.
2. Site Visit and Measurements: We review access, orientation, views, and connection points to your home.
3. Design and Budgeting: We develop a concept, outline materials, and propose glass and HVAC options. You will understand the budget drivers before committing.
4. Detailed Proposal: Clear scope, timeline, and payment schedule with no surprises.
5. Permits and HOA: J Kruzan prepares drawings and coordinates approvals.
6. Pre-Construction Meeting: Review logistics, protection of existing finishes, and schedule milestones.
7. Build Phase: Foundation, framing, roofing, windows, electrical, insulation, drywall, and finishes. Our team keeps the site tidy and communicates progress.
8. Final Walkthrough: We review operations of windows, HVAC, and controls, then handle any final touch-ups.
9. Post-Project Support: J Kruzan stands behind our work and is available for future updates or maintenance.

Most sunrooms build within a few to several weeks once permits are approved. Timeline depends on weather, season, complexity, and customization.

Budget Tips and Planning Insights

Every home is unique, and exact pricing depends on size, structure, glazing, and finishes. Here are practical ways to keep your project aligned with your budget without sacrificing long-term satisfaction.

• Choose a compact footprint: Smart design can make a smaller sunroom feel airy while keeping costs controlled.
• Focus glazing: Use high-performance glass where you need it most and opt for insulated walls on less scenic sides.
• Right-size HVAC: A ductless system sized for the sunroom alone often saves money and improves comfort.
• Plan electrical early: Prewiring for future features avoids costly open-wall changes later.
• Select durable finishes: Materials that handle sunlight and moisture reduce maintenance costs over time.
• Schedule thoughtfully: Off-peak seasons may offer more flexible scheduling.

J Kruzan provides transparent proposals so you can see how each choice affects cost. Our goal is to guide you to a design that delivers the comfort you want at a sensible investment.
