Large sliding patio doors create a beautiful connection between indoors and outdoors. They let in plenty of natural light and often offer a stunning view of the garden, terrace, or the Mediterranean Sea. At the same time, sliding patio doors are one of the biggest sources of heat in a home.

Especially during the hot summer months on the Costa Blanca, indoor temperatures can rise quickly when the sun shines on the glass for a long time. That’s why more and more homeowners are choosing custom screens as an effective solution against heat and annoying sunlight.

Why do sliding patio doors let in so much heat?

Modern homes increasingly feature large glass surfaces. While this creates a spacious feeling and lots of daylight, glass has one major drawback. As soon as the sun shines on the glass, the surface heats up and transfers this heat to the interior space.

With large sliding patio doors, this effect is even stronger because the glass surface is significantly larger than with standard windows. As a result, a living room or kitchen can become noticeably warmer during the day.

Many people try to solve this with curtains or interior sunshades, but by then the sun has already reached the glass. The heat is already inside the home at that point.

Why are screens ideal for sliding patio doors?

Screens are installed on the outside of the home. This blocks a large part of the solar radiation before it reaches the glass.

This means the sliding door heats up less and the indoor temperature stays better controlled. Especially with large glass surfaces, this difference is often immediately noticeable.

Additionally, screens maintain the open character of the home. You still benefit from natural light and an outside view, while the heat load is significantly reduced.

Preserving the view and natural light

One of the biggest advantages of screens is that you are not completely cut off from your outdoor space. Unlike shutters, the view remains intact and the home continues to feel bright and spacious.

Depending on the chosen fabric, you can still look outside during the day while reducing visibility from the outside. This creates a pleasant combination of privacy, daylight, and comfort.

For homes with views of the sea, mountains, or a garden, this is often an important reason to choose screens.

Perfect for modern villas and apartments

Sliding patio doors are widely used in modern villas and apartments on the Costa Blanca. These homes benefit optimally from the advantages of screens.

Thanks to their sleek design, screens perfectly complement modern architecture. When rolled up, they mostly disappear into the cassette, preserving the minimalist look of the home.

For apartments, screens also offer extra privacy without residents losing their view.

Zipscreens for large sliding patio doors

For larger sliding doors, zipscreens are often chosen. The fabric is firmly held in the side guides, making the system more resistant to wind.

This is especially interesting for homes by the sea, penthouses, and higher-level apartments where wind load plays an important role.

Thanks to this construction, the fabric remains taut and the system continues to function reliably even under challenging weather conditions.

Screens or shutters for sliding patio doors?

Are you unsure between screens and shutters? Both systems help keep heat out but are designed for different purposes.

Screens are ideal when you want to maintain an outside view during the day. Shutters offer maximum darkening, extra insulation, and complete privacy.

For living rooms and large sliding doors, screens are often considered the most comfortable solution. For bedrooms, many people prefer shutters.
