Signs your glass is costing you
Your windows shouldn't run the thermostat.
- Employees or customers fight afternoon glare on screens and counters
- Perimeter rooms run hotter than interior spaces
- Blinds stay closed all day, blocking the light you paid for
- Furniture, flooring, displays or merchandise are fading
- Cooling costs keep climbing on glass-heavy floors
How solar control film works
Reject the heat before it enters the room.
Solar control film is a thin, optically engineered layer applied to the inside of existing glass. It rejects part of the sun's heat and glare before it enters the space — so rooms stay more even in temperature and screens stay readable.
The U.S. Department of Energy estimates that about a third of a building's cooling load enters through windows. LLumar retrofits typically save 5 to 15 percent on energy. (Source: LLumar Commercial Architectural Film brochure.)
Lower cooling load
Less strain on HVAC, which can help reduce cooling costs.
Fade protection
Reduces damage to furniture, flooring and displays. No film stops fading completely.
Daylight stays
You keep the views and natural light instead of closing the blinds.
No window replacement
Applied over existing glass, with installation planned around your operating hours.
Manufacturer backing
LLumar films carry a manufacturer's limited warranty and are installed by trained professionals.
LLumar film families
Specified to the glass, the exposure and your goals.
We specify the film to the glass, the exposure and your goals — not from a shelf.
Reflective
Impressive solar control with a mirror-like finish that reflects daylight — maximum heat and glare rejection.
Dual-Reflective
Reflective exterior, neutral interior — significant solar control with clear views out, day and night.
Neutral
Subtle, non-reflective gray films that deliver solar benefits with minimal change to the glass.
Specialty
Virtually invisible solar control with maximum optical clarity — a strong fit for storefronts and historic buildings.
Ceramic
Less reflective appearance with excellent solar control, and durability that holds up in coastal air.
Harmony
Tempers excessive heat and glare with low reflectance and a warm, earthy look.
Spectrally Selective
Maximum heat protection with minimal light control — barely alters the look of the glass.
Low-E
Lowers energy use year-round: reflects heat out in summer and insulates it in during winter.
Who it's for
Glass-heavy buildings that run hot.
- Office buildings and tech campuses
- Retail storefronts and showrooms
- Medical and dental offices
- Schools and public buildings
- Restaurants with sun-exposed seating
- Warehouses and light-industrial offices
Our process
Scoped before we touch a panel.
Site walkthrough
We review glass orientation, panel size, existing film and access — and whether your priority is heat, glare or fading.
Film recommendation
We match the film family and specification to your building and budget, with a clear written quote.
Scheduled installation
Work is coordinated around your hours to limit disruption to staff, tenants and customers.
Final walkthrough
We inspect every panel with you before we call it finished.
Solar control, answered plainly.
Will the film make my space dark?
It depends on the film. We show you samples so you can choose how much light and reflectivity you want before anything is installed.
How much will I save on cooling?
Savings depend on your glass, orientation and HVAC. LLumar retrofits typically save 5 to 15 percent on energy. (Source: LLumar Commercial Architectural Film brochure.)
Will it void my window warranty?
It can with some window manufacturers, especially on dual-pane units. We check the glass type and the window manufacturer's requirements before we recommend a film.
How long does installation take?
It depends on the number and size of panels. A standard storefront can often be installed in one day, and we give you a schedule with your quote.

“This team did a fast and quick job. Everyone loves the tint and especially great for the heat control from the blazing sun shining in. Everyone should have some tint on their windows. I was way better than the blinds my landlord gave me.”
