The Spanish sun is one of the main reasons why so many people choose a home on the Costa Blanca. The pleasant climate, many hours of sunshine, and outdoor lifestyle make this region especially attractive. Yet that same sun also has a downside. Especially homes with large windows and sliding doors can quickly heat up during the summer months, reducing indoor comfort and increasing the need for air conditioning.

One of the most effective ways to keep heat out is to install custom screens. Unlike curtains or other forms of indoor sun protection, screens block the sun before it reaches the glass. This means the heat is blocked on the outside of the house, keeping the inside noticeably cooler.

Why does a house get so warm?

Many people think that heat mainly comes in through open windows. In reality, most of the heat is caused by solar radiation on glass. As soon as the sun shines on a window or sliding door, the glass heats up. This heat is then transferred to the interior, causing the indoor temperature to rise further.

Especially modern villas and apartments on the Costa Blanca often have large glass surfaces. This provides a lot of natural light and a beautiful view, but also makes homes more sensitive to overheating. Especially when windows face south or west, the indoor temperature can quickly rise during the afternoon hours.

With screens, this problem is tackled at the source. The fabric is located on the outside of the window, which blocks a large part of the solar radiation before it reaches the glass.

Why are screens so effective against heat?

The big difference between screens and indoor sun protection is the position of the system. With curtains, blinds, or roller blinds, the sun has already reached the glass before the heat is blocked. This causes the room to still warm up.

Screens work on the outside of the house. This means a large part of the heat is blocked before it reaches the glass. That makes screens one of the most effective forms of external sun protection in Spain.

Besides reducing heat, screens also reduce glare on TVs, laptops, and other screens. This creates a more pleasant living and working environment, even during the hottest months of the year.

Less dependence on air conditioning

Air conditioning obviously provides cooling but also comes with energy costs. When a home heats up less quickly, the air conditioner doesn’t have to work as hard to maintain a comfortable temperature.

Many homeowners notice that rooms with screens feel more comfortable during the day. Especially living rooms with large sliding doors, conservatories, and bedrooms with a lot of sun exposure benefit from this type of sun protection.

Preservation of view and natural light

An important advantage of screens is that they block heat without completely cutting you off from the outside world. Unlike roller shutters, the view remains and pleasant daylight continues to enter.

Depending on the chosen fabric, you can still look outside while significantly reducing visibility from the outside. This way, screens combine privacy, comfort, and an open feeling inside the home.

This makes screens particularly popular in apartments with sea views, modern villas with panoramic windows, and homes where people want to fully enjoy the view.

Ideal for large windows and sliding doors

More and more homes on the Costa Blanca are being built with large glass surfaces. Although this provides a lot of natural light and a spacious feeling, it also causes greater heat load during the summer months.

Especially with large sliding doors and tall windows, screens prove their added value. They create an effective barrier against the sun without compromising the appearance of the home.

For many homeowners, screens therefore form the perfect balance between comfort, appearance, and energy efficiency.

Screens or roller shutters: what is the best choice?

A frequently asked question is whether screens or roller shutters are the best solution against heat.

Although both systems help to reduce the temperature inside the house, there are clear differences. Screens are designed to keep heat out while maintaining the view outside. Roller shutters, on the other hand, focus on maximum darkening, extra insulation, and complete privacy.

Which solution fits best depends on your home, the position of the windows, and your personal preferences. In some situations, a combination of both systems is even chosen.

Wind-resistant screens for the Costa Blanca

Besides sun, wind also plays an important role on the Spanish coast. That is why modern screens are often designed as zip screens. In this system, the fabric is firmly held in the side guides, allowing the system to remain stable even at higher wind speeds.

For apartments, penthouses, and homes by the sea, this is an important advantage. The fabric remains taut and is better able to withstand the conditions typical of the Costa Blanca.

Thanks to this technology, screens are not only suitable for sheltered homes but also for locations where there is regularly more wind.

Electric screens for maximum comfort

Nowadays, most screens are electrically operated. With the push of a button, you immediately create shade and cooling. In addition, there are systems available that automatically respond to sunlight and weather conditions.

This way, you don’t have to intervene manually all the time and you can fully benefit from the advantages of outdoor sun protection.

Having screens installed on the Costa Blanca

The success of screens is not only determined by the product itself. Equally important are the right choice of system, the quality of the fabric, and professional installation.

No home is the same. The position of the facade, the amount of sunlight, the size of the windows, and the influence of wind all play a role in choosing the right screen solution.

That is why we always look at the specific situation of your home. Based on that, we recommend a system that not only looks good but also truly provides more comfort and reduces heat load.

At Port of Altea, we handle the entire process. From personal advice and measuring to delivery and professional installation. This way, you are assured of a solution that perfectly fits your home and your needs.

For which homes are screens suitable?

Screens are used in various types of homes on the Costa Blanca. From modern villas with large glass sections to sea-view apartments and traditional homes with high sun exposure.

Especially homes with large sliding doors, tall windows, and facades facing south or west benefit from the advantages of screens. Heat can build up strongly there during the day.

By blocking the sun before it reaches the glass, a more pleasant indoor climate is created without losing the view.

Tailored advice for your home

The right screen depends on several factors. Not only the window dimensions matter, but also the desired privacy, the amount of light, and the orientation of the home.

That’s why we always advise our customers personally. This way, you can be sure you are investing in a solution that truly makes a difference during the warm Spanish summers.
