What are External Blinds?

External blinds are shading devices installed on the exterior of a building, designed to regulate sunlight and heat entering the interior space.

These blinds are typically made with an aluminium frame and tough fibreglass fabrics, and are adjustable to control the amount of light and heat allowed into the building.

How do External Blinds Work?

External blinds intercept and reflect sunlight before it reaches the windows, blocking solar heat and reducing glare.

By creating a barrier between the exterior and interior of a building, they help maintain cooler temperatures inside, ultimately reducing the need for artificial cooling.

However, external roller blinds still allow light to enter the room, while occupants can also see outside.

Benefits of Our External Blinds

external blinds1

Reduce or Prevent Overheating:

Windows act in a similar way to radiators when the sun is out – heat from the sun travels through the glass, but then can’t travel back out again. The larger the windows, the more heat enters the room.

Studies have shown that installing exterior blinds can reduce indoor temperatures by up to 5 degrees or more, compared to a house with no shading.

Five degrees can be the difference between a comfortable living environment and stifling heat.

a sustainable cooling choice

A Sustainable Cooling Choice:

Exterior blinds require only a small power supply to raise and lower the blinds once installed. Unlike air conditioning, they do not require a constant electricity supply, and are therefore a much more energy efficient and sustainable cooling method.

A single 480 Watt AC unit uses approximately 0.48 kWh per hour, or 11.52 kWh per day. To put that in perspective, an average 4+ bedroom home with 4-5 occupants uses approximately 11.78 kWh per day. Using a single AC unit could double your energy usage and electricity bill.

maintain natural light

Maintain Natural Light and Outside Views:

The unique heat reflecting fabrics external blinds use reflect heat but still allows light into your house. This reduces the need for artificial lighting while also preventing glare and protecting furniture from sun damage.

In addition, the open weave of the fabric allows you to see through the blind to the outside. Unlike shutters or venetian blinds, Renson external roller blinds allow you to continue to enjoy your views while remaining comfortable on hot days.

smart home automation

Compatible with Smart Home Automation:

Control your blinds remotely via an app or by connecting them to your home automation system. You can even install along with sensors to lower the blinds when the room reaches a certain temperature.

This gives you control over the climate of your home, allowing for example to lower the blinds while you’re out to ensure the house stays cool through the day.

Gloucester County Cricket Ground

Renson® Fixscreen blinds were installed to the windows of 5th floor penthouses to prevent overheating and increase comfort for residents. Without the blinds, the inside temperatures were hitting temperatures of 28°C on average. Once installed, the Fixscreen blinds brought the average indoor temperature down to around 21°C.

Where Can External Blinds Be Installed?

Outdoor Living Areas:

Exterior blinds help to provide extra comfort and privacy for your outdoor living areas. By sheltering from both sun and rain, you can enjoy being outdoors regardless of weather conditions. Renson exterior blinds are also compatible with the Renson range of outdoor pergolas.

Keepers Cottage

The owner of Keepers Cottage in Somerset wanted to enclose an existing outdoor living area to make it more comfortable and usable throughout the year.
