Ontario Window Replacement provides professional low-e glass window installation in Ontario, CA for residential and commercial properties across the West End of the Inland Empire. There are two kinds of Low-E coating and they are made in completely different ways. Which one you are being quoted decides what the glass can do and even where it can be used, and almost no proposal in this city says which.
Both are metal on glass, thin enough to see through, working by reflecting radiant heat rather than absorbing light. That is what separates any Low-E from a tint. A tint dims the room to cut heat. A coating pushes back the infrared band and leaves the visible band largely intact.
The first kind is applied during glass manufacture, while the ribbon is still hot, and it bonds into the surface. It is durable. It can be handled, shipped and even used as a single exposed pane, which is why it turns up in storm panels and some reglazing work. What it does not do is control solar heat as strongly as the other kind.
The second kind is deposited afterward in a vacuum chamber, layer by layer. It is a far better solar-control product and it is physically delicate, so it has to live on a protected surface inside a sealed insulated unit. That is the family a West End house wants, because Zone 10 summers are about keeping the sun's heat out rather than about holding furnace heat in.
The consequence is practical. If someone offers to put high-performance solar-control glass into a single-pane sash, the physics does not allow it. The strong coatings require the sealed cavity. Going from one pane to two is what makes that coating possible in the first place.
Within a sealed unit the position is set at the factory. The film belongs immediately inside the pane that faces the street, so it meets the heat before the sealed space does. Nobody relocates it later and no label tells you it moved.
None of this can be checked by looking, since the layer is close to invisible. Read the paperwork instead. Residential work goes in on a CF1R certificate of compliance with the permit application, the installer signs a CF2R-ENV-01-E once the units are set, and the NFRC label on the unit is what the inspector and the compliance form read. Settle the permit question with Ontario's building department early rather than taking a bidder's word.
There is one more distinction worth having in hand. A coating is a property of the glass, and the rated performance belongs to the assembled unit, so the frame material does not change what the coating does. A dark aluminum frame and a white vinyl frame carrying the same glass are carrying the same coating.
Our recommendation. Ask which coating family and which product name, per opening. Specify the strong solar-control glass on the west and south elevations, and accept a clearer unit where no sun lands, since heavy solar glass on a north opening trades away daylight for a benefit that is not there.
Sound dual-glazed units are worth keeping even when a newer coating exists. Which label figure governs here is covered on our energy-efficient windows page, and the gas fill on the double-pane page.
Our insured and bonded team brings the right materials and equipment to every job — center-set aluminum storefront framing in 1-3/4 by 4-1/2 inch profiles, dry-glazed EPDM gaskets and wet-glazed structural silicone joints, subsill flashing with end dams under storefront base members, tempered and heat-strengthened lites carrying CPSC 16 CFR 1201 labels, aluminum entrance doors with the 10 inch ADA bottom rail, offset pivots, top jamb closers and concealed vertical rod exit devices — and backs the work with a written workmanship warranty. We serve Ontario and nearby communities including Chino, Chino Hills, Montclair, Upland.

Materials, equipment and how we do low-e glass window installation
The difference between low-e glass window installation that lasts and low-e glass window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with center-set aluminum storefront framing in 1-3/4 by 4-1/2 inch profiles, dry-glazed EPDM gaskets and wet-glazed structural silicone joints, subsill flashing with end dams under storefront base members, tempered and heat-strengthened lites carrying CPSC 16 CFR 1201 labels, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Ontario job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the West End of the Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Ontario Chooses Ontario Window Replacement
- ✓Two estimating methods, and the quote says which one you are reading. Residential is per opening. Commercial is glazed square foot plus framing linear foot, with the after-hours premium shown on its own line instead of buried in a unit price.
- ✓We hold the CSLB C-17 glazing classification, the one that covers commercial glass. A great deal of residential window work in this region is sold by outfits that cannot legally glaze your storefront, and they rarely volunteer that.
- ✓Warranty documents are never merged. A house gets the manufacturer's residential terms. A commercial opening gets the commercial terms, which are shorter, and we would rather explain why now than have you find out in year eleven.
- ✓Permit path stated before you sign. Residential retrofit is usually over the counter. Commercial can mean plan check, an accessibility review of the path of travel, and an inspection sequence that quietly decides your schedule.
