Heat Rejection Film
The hottest west-facing glass in Florida, calmed. 78% of solar energy rejected at the pane, with night-time views kept clear from inside.
Cuts cooling costs
Rejects 78% of solar heat before it enters
Stops the hot spots
94% of infrared heat turned away at the glass
Views stay clear
Low interior reflectance keeps night views clean
Protects interiors
99% UV blocked to slow fading and sun damage
78% of solar energy rejected
Stops nearly four of every five joules at the glass. The difference between a room your HVAC can't keep up with and one that stays comfortable.
94% infrared rejection
Near-infrared carries the felt heat through glass. Rejecting 94% is noticeable the moment you walk past a treated pane.
Clear night views
Interior reflectance of 15% keeps the glass from reading as a mirror after dark. The view stays clean.

Walk-through first
Every job starts with us on-site, walking your glass in person so the spec matches the building.
Specified per pane
We don't put the same film on every window. Each pane gets matched to orientation, glass type, and what you need it to do.
One crew, start to finish
The team that surveys your glass is the team that installs the film. No handoffs, no subcontractors.
What clients ask about heat rejection film.
How is this different from your Reflective Film line?
+
Both reject solar energy, but they're tuned for different goals. Our dual-reflective line prioritizes clarity of view and a soft interior look. Heat rejection is the highest-performance tier we install: 78% total solar energy rejected and 94% infrared rejection. It reads as a darker, more reflective glass from outside, which is the trade-off for that level of thermal control.
Will it look mirrored from inside at night?
+
No. Interior visible reflectance is 15%, specifically tuned to keep night-time views clean. That's the whole point of the Optivision construction: maximum exterior reflectance and heat rejection without the mirror effect on the inside.
How much will it cut my cooling bill?
+
On west-facing and unshaded glass, most clients see 20 to 40% off cooling costs after a heat-rejection install. SHGC drops from 0.73 on bare 6mm clear glass to 0.21 with the film, which is the single biggest thermal lever you can pull without replacing the glazing.
Is it safe for low-e or laminated impact glass?
+
We verify the glass type during the site survey before recommending heat-rejection film. The Optivision construction is rated for clear single-pane and annealed laminated units without thermal-stress risk. On certain low-e IGUs we spec an alternate product to keep the warranty intact.
