Brise soleil can come in many shapes and styles, but at their most basic, they are a form of sunshade, designed to protect the inside of a building from excess light and heat. If you want to install a brise soleil, it will probably be helpful to understand how they work.
The Basics
Originating from French words meaning “broken sun”, the term “brise soleil” is used to refer to a range of physical structures attached to the outside of the building to block the passage of sunlight, thereby preventing it becoming too hot or bright. Different shapes and designs are available.
The Mechanics
To install an effective sunshade, you need to consider both the design of the building, and the local climate. Experts such as those at alusystems.uk/brise-soleil-solar-shading can help with this. For instance, in the United Kingdom, south-facing buildings receive the most sunlight, whilst those facing the north have the least exposure. There will need to be a calculation of angles based on the arc of the sun through the day and the relative difference in light levels at various times. A good shade will still allow light in the early morning and later in the afternoon whilst protecting against midday brightness. You may see brise soleil with horizontal or vertical layouts in a fixed or adjustable design with various patterns of blades.
The wide range of styles for brise soleil means you should be able to choose a design that suits your taste and the surrounding architecture. The most important thing is that it works effectively to block excess sun.
