If you own rental properties on Long Island, you already know the complaints. The upstairs unit is too hot in summer. Tenants want curtains on every window for privacy. A first-floor bathroom has no privacy but needs natural light. Ground-floor windows feel vulnerable.
Window film solves all of these problems — and it costs a fraction of what you'd spend on new windows, blinds, or HVAC upgrades. Here's what Long Island landlords need to know before their next install.
Why Landlords Love Window Film
Unlike most upgrades, window film stays with the building. When a tenant moves out, the film stays on the glass. You don't have to re-install or replace anything. One investment, permanent benefit.
It also works silently in the background. Tenants don't need to adjust it, clean it differently, or think about it. It just makes their apartment more comfortable — which means fewer complaints to you.
The Biggest Problem Window Film Solves for Landlords
Heat. Long Island summers are brutal, and rental units — especially upper floors and south- or west-facing rooms — can turn into ovens by mid-afternoon. When that happens, your tenants run the AC constantly. If utilities are included in rent, that comes out of your pocket. If tenants pay their own utilities, they complain and you get turnover.
Solar window film blocks up to 80% of the heat trying to push through your glass. Rooms that used to hit 85 degrees on a July afternoon stay significantly cooler — without any change to the AC system. CoolVu of Long Island has installed solar film in multi-family buildings across Nassau and Suffolk County with exactly this result.
Privacy Film for Ground-Floor Units and Bathrooms
Ground-floor apartments on Long Island — in Garden City, Hempstead, Huntington, Bay Shore, and dozens of other towns — often have windows that face sidewalks or driveways. Tenants feel exposed. Most solution? They put up heavy curtains and block all the light.
Privacy film is a better answer. One-way privacy film lets your tenant see out during the day while blocking the view from outside. Frosted film is perfect for bathrooms and glass doors — it looks clean and modern, and it lasts indefinitely. No curtains needed, and natural light is preserved.
Safety Film: Smart Protection for Street-Level Glass
First-floor windows and glass doors are a vulnerability for rental properties. Safety and security film holds glass together if it breaks — whether from a storm, an accident, or a break-in attempt. Instead of shattering into dangerous shards, the glass cracks but stays in place.
On Long Island's South Shore especially, where nor'easters and tropical systems roll through every fall, this is worth thinking about. Safety film is particularly popular in storefronts, but CoolVu installs it in residential units too. It's invisible once applied and requires no maintenance.
UV Protection Saves Your Floors and Your Appliances
Wood floors, laminate, carpets, and even kitchen cabinets fade when UV rays hit them day after day. In a rental unit, that means wear and tear comes faster — and turnover repairs cost you money. CoolVu's window films block 99% of UV rays, which dramatically slows the fading process.
Think of it like sunscreen for your building's interior. The furniture you provide, the floors you installed, the paint you chose — all of it lasts longer when UV is blocked at the glass.
What to Expect from a CoolVu Install in a Rental Unit
Most single-unit or apartment-building installs in Nassau and Suffolk County are completed in one day. Tenants can be home during the install — it's not disruptive and doesn't require moving furniture. The film is dry and usable within a few hours.
CoolVu of Long Island offers a lifetime residential warranty on all film installations, which covers both the product and the labor. If something ever goes wrong with the film, we come back and fix it. That warranty transfers when tenants change — you're covered indefinitely.
What It Costs (and Why It Pays for Itself)
Window film is priced by the square foot of glass. For a typical Long Island rental unit, a solar film install might run a few hundred dollars per unit — significantly less than replacing windows or installing new HVAC equipment. And unlike those options, film doesn't require permits, major construction, or tenant displacement.
The payback is quick. Lower energy use, fewer tenant complaints, less wear on floors and furnishings, and the security benefit of safety film — most landlords with multiple units find that film pays for itself within a couple of summers.
