5 Top Tips for Stopping the Sun

You want to find the perfect solution to find the balance between letting the sun in and keeping the sun out – and it’s different for everyone.

You Can Keep Your View

You don’t have to sacrifice your view just because the sun beats down dangerously during the day.

Professionals can install the latest window tinting technology. Or, you can go the DIY route and find a privacy or blackout film that is easily applied.

Tinted sliding glass doors do more than simply block the sun’s UV rays.

  • You can see out, and your neighbors can’t see in, which improves your privacy.
  • Adding tint or film to your sliding glass door increases security because the glass is harder to shatter. A sliding glass door is a common point of entry for bad guys.
  • Damaging UV rays can’t only hurt you, but they can contribute to fading furniture. And leads to avoidable wear and tear to artwork and personal items.
  • Regardless of which direction your glass door is located, it will give off a glare that will annoy you. Tint easily fixes that.
  • And most window tints or films will block out the heat during the hottest part of the day by reflecting and absorbing solar energy.

Sheer panels or opaque curtains are a simple and affordable way to block the sun. You aren’t sacrificing aesthetics, either.

On the rod closest to the window, hang a sheer or transparent print that allows the sun in.
