Adapting to climate change is also about working with what we already have.

Sash windows were engineered to aid ventilation.

Opening both sashes equally allows hot air to rise and escape through the top opening while cooler air flows in from below, creating natural air circulation that can regulate indoor temperatures.

This practice works best when the air outside is cooler than the air inside.

Our awning attaches directly to the top sash and moves with the window, so you can block the sun and create air circulation at the same time.

Free that sash girl!!!
