Solar Heat Rejection: The Window Treatment Upgrade That Fights Back Against DMV Summers

Direct sunlight through a south or west facing window does more than create glare. A large share of the sunlight hitting a standard double pane window converts directly into indoor heat, driving up cooling costs and forcing air conditioning systems to work harder through the hottest months of the year. Solar heat rejection is the term for window treatments built specifically to fight that effect.

How Solar Heat Rejection Works

Solar shades use specialized high performance fabrics that reflect infrared radiation rather than absorbing it, cutting down the heat that makes it into a room while often preserving the outside view. Cellular shades take a different approach, trapping pockets of air in a honeycomb structure that acts as insulation against heat transfer in summer and heat loss in winter. Both approaches can meaningfully reduce cooling costs during peak season, with some estimates putting the reduction as high as 25 percent.

Automation Adds a Second Layer of Protection

A solar shade only rejects heat while it is closed, which means a shade left open during peak afternoon sun provides no benefit at all. PowerView Automation solves that gap by closing shades automatically before the hottest part of the day arrives, then reopening them once direct sun has passed, all on a set schedule that requires no one to be home or paying attention.

This season, PowerView Automation comes free with the purchase of Silhouette or Pirouette Window Shadings, through September 30. Both collections filter harsh light while reducing heat gain, and pairing either one with free automation turns a passive upgrade into an active, scheduled defense against summer heat.

Getting Started

An estimate is the fastest way to see which rooms would benefit most from solar heat rejection and where automation makes the biggest difference.
