Elgin Window Pros provides professional aluminum window replacement in Elgin, IL for residential and commercial properties across the Fox River valley in Kane County. We do not put residential aluminum into a heating climate, and we are not going to start. That is the short answer. The useful answer is what to do about the aluminum you already own, which is probably why you are reading this.
The Elgin normals run roughly 6,592 heating degree days against 807 cooling. In that ratio conduction is the only figure worth arguing about, and an uninterrupted aluminum frame is the best conductor anywhere in your wall.
What is usually there is single-glazed aluminum on postwar and 1960s stock, often with a triple-track storm hung outside it, and a sightline narrower than anything built today. People call it a drafty window. Much of the time it is not drafty at all. It is cold.
Those are different complaints with different fixes. Air moving past a bad seal is draft. A surface that pulls heat out of the room by radiation, and sheds water onto the sill when the room air touches it, is conduction. Put a hand on the frame on a January morning and then on the middle of the pane, and you will know which one you have.
What replaced bare aluminum was not a better alloy. It was a deliberate discontinuity: a non-metallic web between the weather side and the room side of what used to be one extrusion. That break is why a thermally broken unit behaves nothing like the frame it resembles.
Which leads to the claim this page exists to correct. No Illinois rule bars aluminum, because the energy code says nothing about frame material in the first place. The number is on the certified label, and a properly broken aluminum unit can reach it. Bare aluminum cannot, and no glass package rescues it.
Elgin is the city where that label gets checked. A permit is required for every replacement here, so the trigger that attaches the state energy code to a job is always satisfied, and the labels stay on the glass and turned outward until the final inspection signs off.
Aluminum is still the right material a mile away from your house. Thermally broken storefront framing set into a captured glazing pocket is exactly where it belongs, and we survey those bay by bay, because a masonry opening that has moved will not accept one repeated unit across a whole elevation.
Here is the recommendation, including the part that costs us work. Where an aluminum frame is sound and the only failure is a clouded sealed unit, buy glass and keep the frame. If you are inside a historic district, repairing original wood sash will clear a certificate of appropriateness in cases where any replacement would have to be argued for.
And where the frame is bare aluminum and genuinely finished, change the whole unit instead of reglazing a thermal bridge. New glass in an old aluminum frame buys you a warmer middle pane, a colder perimeter by comparison, and the same wet sill next winter.
Our insured team brings the right materials and equipment to every job — pan flashing carried a full six inches up both jamb legs, hand-packed mineral wool filling an emptied sash-weight pocket, brickmould and exterior casing left undisturbed on a pocket install, an NFRC label left adhered to the glass and faced outward for final, backer rod bedded behind a tooled sealant joint at the exterior reveal, compression-seal casement hardware bearing on a continuous jamb gasket — and backs the work with a written workmanship warranty. We serve Elgin and nearby communities including South Elgin, St. Charles, Geneva, Batavia.

Materials, equipment and how we do aluminum window replacement
The difference between aluminum window replacement that lasts and aluminum window replacement that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with pan flashing carried a full six inches up both jamb legs, hand-packed mineral wool filling an emptied sash-weight pocket, brickmould and exterior casing left undisturbed on a pocket install, an NFRC label left adhered to the glass and faced outward for final, 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 Elgin 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 Fox River valley in Kane County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Elgin Chooses Elgin Window Pros
- ✓Every opening on our quote is marked insert or full replacement before you sign, because that one word decides the flashing, the permit route and roughly a third of the price.
- ✓Where a full replacement is going in, the pan flashing is a priced line item you can point at, not a detail buried behind trim that nobody ever checks.
- ✓We pull the permit and book the final ourselves, and we leave every label stuck to the glass and turned outward so the inspector can read it from the sidewalk.
- ✓We ask what year the house was built before we price a single window, because a boxed weight pocket and a modern jamb liner are two entirely different jobs.
