What Is a Solarium and How Is It Different From a Sunroom?
If you’ve been exploring ways to expand your living space, you’ve probably come across terms like sunroom, screen room, and solarium. While these words are often used interchangeably, they actually describe very different home additions. Understanding the differences is key to choosing the option that best fits your lifestyle, budget, and Texas climate.
At Sunspace Texas, we specialize in creating custom outdoor living solutions that range from screened porches to year-round insulated sunrooms. Let’s take a closer look at how solariums compare to sunrooms — and why many Texas homeowners prefer the Sunspace sunroom system.
What Is a Solarium?
A solarium is a type of glass enclosure designed to capture as much natural light as possible. Constructed with glass walls and a glass roof, a solarium creates the feeling of being outdoors while staying protected from rain, wind, and pests.
Solariums are sometimes called conservatories, and in cooler climates, they can be a dramatic architectural feature. They’re also popular with homeowners who want to use the space for growing plants or enjoying panoramic sky views.
Solarium Advantages
- Full glass walls and ceiling create an immersive outdoor experience.
- Ideal for stargazing or watching storms from the comfort of indoors.
- Fills your space with natural light — excellent for plants.
- Adds architectural flair to a home.
Solarium Disadvantages
- Overheats in summer — especially in Texas.
- High maintenance: frequent glass cleaning required.
- More expensive to build and maintain.
- Less energy-efficient, leading to higher cooling costs.
- Glass roofs may be vulnerable in severe weather.
What Is a Sunroom?
A sunroom also brings sunlight indoors, but it’s more practical for everyday living. Instead of full glass walls and ceilings, a sunroom combines large windows, screens, and doors with a solid insulated roof.
At Sunspace Texas, we design sunrooms with customizable options like:
- WeatherMaster® Windows & Doors (vinyl panels that block 99% of UV rays)
- Acrylic Patio Covers for filtered natural light
- Walls-Under Systems to convert decks into enclosed spaces
- AlumaDeck® Flooring, slip-resistant and waterproof
- Aluminum Railings that complement decks or stairs
This flexibility allows you to enjoy sunlight without the downsides of an all-glass room.
Sunroom Advantages
- Comfortable year-round with insulation and ventilation.
- Lower maintenance compared to full glass.
- Versatile: can be used as a dining area, office, game room, or breakfast nook.
- Scalable: start with a patio cover and later upgrade to screens or vinyl windows without losing your investment.
- Engineered to exceed Texas building codes, designed to handle high winds and storms.
Sunroom Disadvantages
- Doesn’t offer a complete 360° glass view like a solarium.
- May require skylights if you want overhead sunlight.

Which Is Best for Texas Homes?
While solariums are beautiful, the Texas climate makes them impractical for most homeowners. The all-glass design leads to overheating, higher utility bills, and more upkeep.
Sunspace sunrooms, on the other hand, are designed with insulation, energy efficiency, and storm durability in mind. Whether you start with a patio cover, add screens, or upgrade to vinyl window walls, you’ll enjoy a comfortable, usable space year-round.

Frequently Asked Questions (FAQs)
Is a solarium the same as a sunroom? No. A solarium is all glass (walls and roof), while a sunroom combines windows, doors, and a solid roof for better comfort and efficiency.
Which is better for Texas heat: a solarium or a sunroom? A sunroom is better. Its insulated roof and WeatherMaster® windows are designed to keep the space cool in summer and warm in winter.
Are solariums more expensive than sunrooms? Yes. Solariums cost more to build and maintain due to glass roofing, while sunrooms are more budget-friendly and energy-efficient.
Do I need a permit for a sunroom or solarium in Texas? Most cities require permits for structural additions. Sunspace Texas will handle drawings, approvals, and building code compliance.
Can I start with a patio cover or screen room and upgrade later? Yes. Sunspace systems are modular, meaning you can start with a patio cover, add screens, and later upgrade to vinyl or glass panels.
Are sunrooms energy efficient year-round? Yes. With insulated roofs, vinyl panels, and proper ventilation, a Sunspace sunroom stays comfortable across all four seasons.
Which adds more home value: a solarium or a sunroom? In hot climates, a well-insulated sunroom typically adds more usable living space and resale value than a glass solarium.
