Heat is one of the reasons to want to limit sunlight through those jaw-dropping gorgeous panorama windows of yours. The next reason is the turning on of high cooling and its energy consumption.  The final reason is to save the fabrics and floors that you spent ages selecting so that they would make those dropped jaws hit the floor.

The solution is carefully planned sunlight admittance which can significantly diminish peak heat increases without destroying the natural light. It helpfully also improves your visual comfort by controlling glare and reducing contrast ratios.

During hot seasons external window shading is a top priority to stop heat gain within an interior. Sweating and selfies are not friends.

Shading Elements

Natural landscaping or building elements like overhangs and pergolas can add shading but in the cold months they are a disadvantage and being permanent it is very limiting. A building’s exterior appearance can also be dramatically affected by the adding of overhangs, trellises, pergolas etc. They will also permanently affect that quality of natural light that enters the interior.

Interior window treatments like venetian louvres or curtains do not reduce heat gain as the heat has already passed through the windows before being temporarily trapped by the blinds or curtains.  The heat then slowly seeps into the interior building up to the highest temperature. The interior systems do assist with glare.

Materials And Methods

Over the years there has been a vase array of products available to provide shading in buildings. There are adjustable shading products such as canvas awnings, solar screens, roll-down blinds, shutters, and vertical louvers.

Even the glass specified can assist with heat gain. A U-value, SC and Tvis is good for fenestration systems. The shading coefficient (SC) of a glazing indicates the amount of solar heat gain into a building versus a single-glazed glass. A lower shading coefficient equals less heat gain. The visible transmittance (Tvis) of glass means the percentage of the light available into a building.

With exterior blinds you get the views, the airflow, the connection to the great outdoors, all of this in the comfort and protection of your living space without exposure to the elements. No harsh UV rays, wind gusts or glare from the sun. This makes your living space more versatile by being usable year-round. Nice additional info here: this makes your property more valuable.  Now how cool are you?
