If Your Home Has a Sunroom, You NEED to Read This Before Summer.

Sunrooms are a dream for many homeowners. They bring in natural light, offer a cozy spot to enjoy the outdoors without bugs, and add value to your home. But when summer arrives, many sunroom owners face a harsh reality: their beautiful space turns into an unbearable glass oven. If you have a sunroom, you know the struggle all too well—too hot, too bright, too much glare, and an AC system that just can’t keep up. This post explains why your sunroom becomes a problem in summer and what you can do to fix it before the heat hits.

Why Sunrooms Turn Into Glass Ovens

Sunrooms are unique because they are mostly glass. Walls and ceilings made of glass let in sunlight, but that sunlight also brings heat. The glass traps this heat inside, creating a greenhouse effect. This means your sunroom heats up quickly and stays hot, often much hotter than the rest of your house.

The problem is not just the heat. The glass also lets in ultraviolet (UV) rays and infrared (IR) rays, which cause fading and damage to your floors and furniture. Plus, the bright sunlight creates glare that makes it hard to relax, work, or watch TV in the room.

The Dead Room Syndrome

Many sunroom owners face what’s called the “Dead Room” syndrome. From late spring through early fall, the sunroom becomes almost unusable. The heat and glare make it uncomfortable to spend time there, so the room sits empty. Imagine spending $25,000 or more on a sunroom addition and only using it for a few months each year. That’s frustrating and feels like wasted space.

The AC Battle You Can’t Win

Your air conditioner works overtime trying to cool the sunroom. Because the glass traps heat, the AC has to run 30 to 50 percent more than usual. You might notice higher energy bills and still feel like the room never cools down enough. The AC blows cold air in, but the glass walls and ceiling send heat right back inside. This constant battle is exhausting for your system and your wallet.

Your Floors and Furniture Are Paying the Price

Sunrooms cause floors and furniture to fade much faster than other rooms. Hardwood floors can fade 3 to 5 times faster, costing between $800 and $2,500 to refinish or replace. Luxury vinyl plank (LVP) flooring and rugs also suffer, with replacement costs ranging from $1,200 to $3,000 for LVP and $500 to $1,500 for rugs. Upholstered furniture can bleach and lose color, with costs over $1,000 to replace or reupholster.

This fading happens because UV rays break down the pigments in your materials. When you see uneven color or sun spots, it’s a clear sign your sunroom needs protection.

Glare Makes the Room Miserable

Bright sunlight causes glare that makes it hard to enjoy your sunroom. You might find it impossible to watch TV, work on a laptop, or even relax without headaches or burning eyes. The glare can also cause sweating indoors, making the room feel sticky and uncomfortable.

The Greenhouse Effect Creates a Sticky, Sweaty Room

The combination of heat and humidity in a sunroom creates a suffocating environment. The glass traps moisture and heat, turning the space into a sweaty, sticky room that no one wants to spend time in. This effect worsens in humid climates, making your sunroom feel like a sauna.
