My Buying Guide on Best Thermal Curtains For Sliding Glass Doors
When I first moved into my home, I quickly realized how much heat could escape through my sliding glass doors. The cold drafts in the winter and the blazing heat in the summer made me feel uncomfortable. That’s when I decided to invest in thermal curtains. If you’re in a similar situation, let me share my experiences and tips on finding the best thermal curtains for your sliding glass doors.
Why Choose Thermal Curtains?
Before diving into my recommendations, let me explain why I opted for thermal curtains. These specially designed curtains are lined with insulating materials that help regulate indoor temperatures. They keep the cold air out in winter and block the sun’s heat in summer. Plus, they add a layer of privacy and style to my home.
Key Features to Look For
When I was shopping for thermal curtains, there were several key features I made sure to consider:
- Material: I found that polyester and a blend of polyester with cotton or linen worked best for insulation. The thicker the fabric, the better it performed in blocking drafts.
- Lining: Look for curtains with a blackout lining. This not only improves insulation but also helps in blocking out light, which is a bonus for daytime naps.
- Length and Width: I made sure to measure my sliding glass doors carefully. Curtains should ideally touch the floor to maximize energy efficiency and aesthetic appeal. I found that extra-wide panels provided better coverage and style.
- Style and Color: Since I wanted my curtains to complement my decor, I chose a color that matched my room. Many thermal curtains come in various styles, so you can find something that fits your taste.
- Ease of Installation: I preferred curtains that were easy to install, especially since I didn’t want to deal with complicated setups. Look for rod pocket or grommet styles that can be hung easily.

- Layering: If I wanted to add more insulation, I considered layering with sheer curtains for added style and flexibility.

- Regular washing: I washed my curtains according to the label instructions, usually on a gentle cycle.
- Avoid direct sunlight: Whenever possible, I closed them during peak sun hours to prevent fading.
