Why Blackout Curtains for Sliding Glass Doors Are Necessary
From my experience, blackout curtains for sliding glass doors have been a game-changer in my home. Sliding glass doors let in a lot of natural light, which is great during the day, but when I want to sleep in or watch a movie without glare, that light becomes a problem. Blackout curtains completely block out sunlight, giving me the darkness I need for better rest and a more comfortable living space.
Another reason I find blackout curtains essential is privacy. Sliding glass doors often face neighbors or busy outdoor areas, and I don’t always want people peeking inside. With blackout curtains, I can enjoy my privacy without worrying about anyone looking in, especially at night when my interior lights are on.
Lastly, blackout curtains help with temperature control. My sliding glass doors tend to let in heat during summer and cold drafts in winter. These curtains provide extra insulation, helping me keep my home cooler or warmer as needed, which also lowers my energy bills. Overall, blackout curtains have made my sliding glass doors more functional and comfortable in everyday life.
My Buying Guides on Blackout Curtains For Sliding Glass Door
When I first started looking for blackout curtains for my sliding glass door, I quickly realized there’s more to consider than just picking a pretty fabric. Sliding glass doors are large and often let in a lot of light, so finding the right blackout curtains can make a huge difference in privacy, temperature control, and overall comfort. Here’s what I learned during my search that might help you too.
1. Measure Your Sliding Glass Door Accurately
Before anything else, I measured my sliding door carefully. I made sure to measure the width and height of the entire door frame, not just the glass part. For blackout curtains, it’s best to add a few extra inches on each side and at the top so the curtains fully cover the door and block out as much light as possible. This prevents light leaks around the edges.
2. Choose the Right Fabric and Thickness
I discovered that not all blackout curtains are created equal. Some are just thick fabrics, while others have a special blackout lining. For sliding doors, I recommend curtains with a triple-weave or thermal lining because they block light better and also help insulate against heat and cold. This was especially important for me during summer and winter.
3. Consider the Curtain Style and Hanging Method
Sliding glass doors need curtains that are easy to slide open and close. I preferred grommet-top curtains because they glide smoothly on a sturdy curtain rod. However, some people like panel curtains on a track system for a cleaner look. Also, I made sure the rod or track I chose was wide enough to allow the curtains to stack back without blocking the doorway.
4. Color and Aesthetic
Since blackout curtains are usually thicker and sometimes heavier, I wanted them to complement my room’s decor. Dark colors like black or navy typically block the most light, but I found some lighter colors with blackout lining that worked well too. Think about your room’s style and how much natural light you want when the curtains are open.
5. Easy Maintenance
Because sliding doors often get more exposure to dust and dirt, I looked for blackout curtains that were machine washable or easy to clean. Some require dry cleaning, which can be inconvenient. I also checked customer reviews to see how well the curtains held up after washing.
6. Budget and Quality Balance
I set a budget but didn’t want to sacrifice quality. Cheaper curtains might not block light fully or could wear out quickly. Investing a bit more in curtains with good reviews and durable fabric paid off in the long run.
7. Additional Features to Look For
Some blackout curtains come with extra benefits like thermal insulation, noise reduction, or UV protection. Since my sliding door faces a busy street, I found noise-reducing blackout curtains made a noticeable difference in reducing outside sounds.
Final Thoughts
Buying blackout curtains for a sliding glass door is a bit different from regular windows because of the size and usage. Taking the time to measure properly, choose the right fabric and style, and consider maintenance and budget helped me find curtains that not only block light but also enhance my living space. I hope my experience helps you pick the perfect blackout curtains for your sliding glass door!
