Imagine sipping coffee in January sunshine without a draft, or enjoying a cool July evening without mosquitoes. That is the promise of a well built, energy-smart sunroom. As custom sunroom builders serving Lake Geneva and the surrounding counties, J Kruzan blends design expertise with careful construction so your new space feels comfortable in every season. In this guide, we break down four glass packages engineered for Wisconsin weather, explain pricing and design options, and outline how our team takes your project from idea to reality.

J Kruzan Construction & Remodeling, LLC is a full-service contractor based in Lake Geneva, Wisconsin. We serve homeowners in Walworth, Kenosha, and Racine counties with home remodeling, additions, and custom improvements. Our clients choose us for Old World Craftsmanship paired with modern building techniques, a transparent process, and a friendly team that treats your home with respect.

Why Work With Custom Sunroom Builders Instead of a Kit?

Off-the-shelf kits can look appealing, but Wisconsin’s temperature swings, snow loads, and humidity call for careful design, robust framing, and high performance glass. Custom sunroom builders tailor the structure, thermal design, and finish details to your property and your goals. With J Kruzan, you get a sunroom that integrates with your home’s roofline, complements your architecture, and meets local code. Most important, our team builds to a four-season standard so your room stays comfortable in January and July.

The 4 Glass Packages for True Four-Season Comfort

Glass performance determines most of the comfort inside a sunroom. Our four packages are selected for different priorities: value, energy savings, noise control, and maximum year-round performance. Exact ratings vary by brand and unit size, but these descriptions will help you choose a path with confidence.

Glass Package 1: Energy-Smart Double-Glazed Low-E

This package uses double-pane insulated glass with a Low-E coating and argon gas fill. It is a strong baseline for clients seeking comfort and value without stepping up to triple-pane. A warm-edge spacer helps reduce condensation at the edges.

• Thermal performance: typically a U-factor around 0.28 to 0.30 depending on size and frame
• Solar control: moderate solar heat gain for winter warmth while limiting summer glare
• Best for: three-season use with supplemental heat or cooling, budget-focused projects, sunrooms with some shade
• Why choose it: solid comfort upgrade over clear glass, better fading protection for furnishings, improved condensation resistance

If your sunroom faces east or north, or you plan to add a small ductless heat pump, this package offers a comfortable starting point.

Glass Package 2: Advanced Low-E2 With Argon and Warm-Edge Spacer

Step up to enhanced Low-E coatings for improved winter insulation and better summer control. We still use double-pane glass, but with a more selective coating that blocks a higher percentage of solar heat while preserving visible light.

• Thermal performance: U-factor often in the 0.25 to 0.28 range depending on frame
• Solar control: lower solar heat gain coefficient for sunnier exposures
• Best for: south or west exposures that receive strong sun, clients who want four-season comfort with efficient HVAC integration
• Why choose it: better summer comfort, more even interior temperatures, reduced energy costs compared to basic Low-E

For sunrooms that face the lake or a wide open yard, this package keeps temperatures more stable and reduces the need for blinds during peak sun hours.

Glass Package 3: Triple-Pane Low-E3 With Argon or Krypton Mix

Triple-pane glass is a major comfort upgrade. With three layers of glass and multiple Low-E coatings, the interior glass surface stays warmer in winter and cooler in summer. That reduces drafts and cold spots near big windows.

• Thermal performance: U-factor commonly around 0.17 to 0.22 depending on spacer and gas fill
• Solar control: excellent, with lower solar heat gain in summer while maintaining good daylight
• Best for: true four-season sunrooms, homes near busy roads that benefit from added sound reduction, premium builds
• Why choose it: room feels more like part of the main house, noticeably quieter, improved condensation control during cold snaps

If your goal is a seamless extension of your living space that you can use year-round without sacrificing comfort, triple-pane pays dividends in Wisconsin’s climate.

Glass Package 4: Premium Four-Season Performance With Laminated Solar Control and Acoustic Interlayer

Our top package adds a laminated pane with a specialized interlayer for safety, UV blocking, and noise reduction, combined with advanced Low-E coatings. Many clients choose this option for sunrooms that double as media spaces or quiet reading retreats.

• Thermal performance: U-factor often in the 0.16 to 0.20 range depending on configuration
• Solar control: high performance solar control coating for glare reduction and UV protection
• Best for: year-round comfort, lakefront homes with wind and noise, homeowners who want the quietest, most consistent environment
• Why choose it: top-level comfort and durability, better protection for flooring and fabrics, superior storm resilience

This is the closest you can get to main-house energy performance in a glass-rich room while keeping beautiful views and natural light.

How to Choose Your Glass Package

Start with orientation and lifestyle. A south or west sunroom benefits from stronger solar control, while a north or east space might prioritize insulation. Think about how you will use the room. Daily year-round use points to triple-pane or laminated options, while occasional use with supplemental heat may be comfortable with advanced double-pane. J Kruzan will review sun studies, shading from trees, and your comfort priorities before recommending a package that balances performance and budget.

Design Options That Complement Your Glass Choice

Frame Materials and Thermal Breaks

The frame around your glass matters. We use thermally broken aluminum, insulated vinyl, or hybrid systems that combine strength with low conductivity. A thermal break stops heat from transferring through the frame, which reduces condensation and drafts. J Kruzan will match frame color and profile to your home for a clean, unified look.

Roof Styles That Fit Your Home

We build cathedral, studio, and gable roofs with insulated panels or stick-framed structures that accept roofing to match your home. Insulated roof panels boost year-round comfort, while skylight options add drama and daylight. Snow load design is critical in Wisconsin. Our team sizes rafters, panels, and connections for local conditions and code.

Windows and Doors That Work Hard

Choose casement or awning windows for tight seals and easy ventilation. Sliding doors save space while French doors add classic appeal. All operable units can be specified with your chosen glass package. We also offer internal blinds, high performance screens, and easy-clean coatings to keep maintenance simple.

Built for Wisconsin Weather

Comfort depends on more than glass. Structure, air sealing, and insulation all play a role. As custom sunroom builders, J Kruzan focuses on the parts you do not see that make a big difference in how the room feels.

• Foundations and footings: We design frost-protected foundations to prevent heave and ensure stable floors
• Thermal comfort: Insulated kneewalls and floors, sealed penetrations, and careful transitions to the main house reduce drafts
• Roof integration: Proper flashing and ice dam protection keep your home dry through freeze-thaw cycles
• Moisture control: We plan for humidity swings with venting strategies and material choices that resist condensation

Every project is engineered for the local code and your home’s exact conditions. We coordinate permits and inspections so the process stays stress free.

Pricing and Budgeting for a Four-Season Sunroom

Project cost depends on size, structure, glass package, roof design, and finishes. While every home is unique, it helps to understand what drives cost so you can prioritize features that deliver the most value.

What Drives Cost

• Glass package: higher performance glass increases cost but reduces energy use and improves comfort
• Structure and foundation: more complex rooflines and frost-protected foundations add materials and labor
• HVAC integration: tying into existing systems or adding a ductless unit impacts price
• Finishes: flooring, trim, lighting, and built-ins vary widely
• Site conditions: access, utilities, and grading can affect labor

Typical Investment Ranges

A modest four-season sunroom with an advanced double-pane package often starts at a mid-range investment, while larger cathedral rooms with triple-pane or laminated glass, custom finishes, and integrated HVAC trend higher. J Kruzan provides a clear, itemized proposal so you can see where every dollar goes and make smart tradeoffs. We also help you understand long-term savings from energy-efficient glass and insulation.

HVAC and Comfort Strategies That Work

Comfort is a system. High performance glass is the heart, but heat and cooling should match the room’s use. We often recommend a ductless mini split for precise control without overloading your main system. In some homes, extending existing ductwork is a smart choice. Ceiling fans, solar control shades, and operable windows add flexibility on spring and fall days. Combined with careful air sealing, these strategies keep your sunroom comfortable and efficient.

Maintenance and Care

Modern glass needs simple care to perform well for years. Clean with non-abrasive solutions and soft cloths. Avoid sharp tools on seals and gaskets. Check weep holes and gutters seasonally to keep water moving away from the structure. Laminated and triple-pane units are durable and resist fading, but you should still use care when moving furniture to protect frames and glass surfaces. J Kruzan reviews all maintenance steps during your final walkthrough and provides documentation for your records.

Frequently Asked Questions

Is a four-season sunroom worth it in Wisconsin?

Yes. With the right glass package and insulation, a sunroom becomes a real living space you can use all year. Clients tell us it quickly becomes their favorite room in the house. Better glass improves comfort, cuts glare, and lowers energy use over time.

Do I need triple-pane glass for four-season use?

Not always. Advanced double-pane with Low-E2 can work in many cases, especially with shaded orientations and a good HVAC plan. For the most even comfort and noise reduction, triple-pane is the top choice.

Will my sunroom match my home?

Yes. As custom sunroom builders, J Kruzan designs rooflines, trim, and finishes to complement your architecture. We can match siding and roofing, integrate lighting, and add custom millwork for a seamless look.

How long does the project take?

Timelines vary by size and complexity, but many projects run several weeks from the start of construction. Design, permits, and material lead times add to the schedule. We provide a realistic timeline during the proposal stage and keep you updated.

Can you convert an existing porch or patio?

Often yes. We evaluate the structure, foundation, and headroom. In many cases we can transform a porch or patio into a fully insulated four-season room with one of our glass packages.
