Solar control window film
Reject up to 80% of solar heat, cut HVAC runtime by 20-30%, and eliminate glare on screens and merchandise - all without replacing a single window.
Commercial solar control window film is the fastest ROI capital improvement most building owners can make. A properly spec'd solar film pays for itself in 3-5 years through utility savings alone, and delivers a long list of side benefits: better tenant comfort, less UV damage to merchandise and interiors, reduced glare on screens, and a more uniform exterior facade appearance.
DarkSide installs solar films from the top three US manufacturers, with a specialty in nano-ceramic spectrally-selective films that reject infrared heat without going dark. That means you get the heat rejection benefit without the tenant complaints that come with a bronzed or mirrored look.
How solar film works
Sunlight arrives in three chunks: visible light (what you see), ultraviolet (what fades things), and infrared (what warms things). Cheap absorptive films block all three by getting darker. Modern nano-ceramic films are spectrally selective - they let visible light through while rejecting the IR and UV. The result: your building stays bright and cool, and your view stays intact.
- Reject up to 80% of solar heat gain
- Block 99% of UV rays - stop fading on merchandise, art, and interiors
- Cut glare up to 89% on screens, sales floors, and trading desks
- Reduce HVAC runtime and utility bills 20-30% on sun-exposed facades
- Improve tenant comfort - fewer hot spots, fewer complaints
- Uniform exterior appearance across every window on a facade
- Qualifies for LEED credits under Energy & Atmosphere, EA-1
Fast payback
A 30,000 sqft office building in the Central Valley typically saves $8,000-$18,000 per year in cooling costs after solar film retrofit. On most projects that means a documented payback in 3-5 years, and 25+ years of savings after that. We can pull heat-load modeling for your specific building at no charge to show projected savings.
What we install
We match film to your specific glass. Old single-pane float glass takes a different film than modern low-e insulated glazing. Tempered laminated safety glass has yet another spec. Our free assessment identifies your glazing, pulls the manufacturer compatibility chart, and recommends the specific film that will deliver maximum heat rejection without seal failure risk.

The right film for the job
Nano-Ceramic Neutral
Optically clear, spectrally selective. Maximum heat rejection with minimal appearance change. Ideal for modern glass facades.
Reflective Silver
High heat rejection with a clean mirrored exterior. Common on office buildings, warehouses, and daytime-only occupancy.
Dual-Reflective
Reflective outside, low-glare inside. Preserves view out while cutting heat and glare.
Low-E Retrofit
Adds insulation performance to single-pane or old dual-pane glass. Alternative to full window replacement.
Solar + Security Combo
Nano-ceramic solar layer with 8mil security backing. One install, two benefits.
Neutral Bronze / Charcoal
Aesthetic tint options for buildings that want the darker look without going full-mirror.

Frequently asked questions
How much does commercial solar film cost?
Solar films run $7-$12 per square foot installed depending on grade and access. Multi-story facades with lift access are quoted separately. Most projects pay back in 3-5 years through utility savings.
Will solar film make my building look dark or mirrored?
Only if you want it to. Our flagship neutral ceramic films are nearly invisible from outside. Reflective and bronzed options are available if you want the aesthetic change.
Can solar film damage my dual-pane windows?
Not when spec'd correctly. We only install films the manufacturer has certified for your specific glass. Every install carries a manufacturer warranty against seal failure caused by the film.
Does it qualify for LEED or utility rebates?
Yes - most commercial solar films qualify for LEED Energy & Atmosphere credits. Some utility providers offer rebate programs. We provide the documentation.
How disruptive is the install?
Minimal. We work office-by-office or floor-by-floor and can schedule nights and weekends. No exterior work, no scaffolding required for most buildings.
