Durham Window Pros provides professional thermally broken aluminum windows for masonry openings in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. Everywhere else in the country, the advice on aluminum windows is to avoid them. Metal conducts, the argument goes, and a metal frame in a heating climate is a cold bridge with a view. In Durham's converted industrial buildings that advice is wrong, and following it produces a worse window.
The reason is span. A tobacco warehouse or a cotton mill was daylit before it was electrified, so the openings are tall, wide and numerous, and many of them ran eight feet or more with a steel sash divided into small lites. Nothing in the residential vinyl catalogue holds that dimension. Aluminum does, because it is the only common frame material with the stiffness to do it in a narrow section.
The thermal objection was answered decades ago. A modern thermally broken frame has a poured-and-debridged urethane or a mechanically crimped polyamide strut separating the inside and outside extrusions, and the interior face never touches the exterior one. Whole-product U-factors in the low 0.30s are ordinary in these systems, and better is available if you are willing to pay for it.
Then there is what the building looks like. Original steel sash has frame members around half an inch wide and enormous glass area. Put a vinyl unit with a two-and-a-half-inch frame stack in that opening and the elevation changes character from the street. A thermally broken aluminum system in a matching dark finish keeps the proportion, which is why exterior reviews pass it.
Aluminum also lets us build a structural mullion into a wide opening instead of splitting it into separate units with a brick pier between them. The mullion carries the wind load back to the jambs, so the glass is continuous and the sightline reads as one opening. On a fifteen-foot mill opening that is the difference between a restoration and a compromise.
Anchoring is the part nobody talks about. There is no stud to fasten to. We anchor through the frame jamb into solid masonry, not into a mortar joint that has been repointed twice, at spacings the manufacturer's installation instructions actually specify, with shims bearing at each anchor so the frame is not asked to span between fixings.
Water is managed the way the wall was built to manage it. Masonry is a reservoir, not a barrier: it takes on rain and lets it out again through a through-wall flashing and weeps above the opening. A window set into that wall has to respect the path. Sealing the head joint solid, which happens constantly, traps water in the wall above the lintel.
We do not put aluminum in wood-framed houses. In a 1994 subdivision in south Durham it is the wrong product and a more expensive one, and vinyl or fiberglass will beat it on cost and on U-factor. The recommendation only inverts when the opening is masonry and large. Tell us the wall and the width and we will tell you which side of that line you are on.
Our licensed and insured team brings the right materials and equipment to every job — polyamide strut thermal breaks, steel lintels and relieving angles, through-wall flashing and weep tubes, pultruded composite sash sections, warm-edge stainless spacers, laminated acoustic interlayers — and backs the work with a written workmanship warranty. We serve Durham and nearby communities including Chapel Hill, Carrboro, Hillsborough, Efland.

Why Durham Chooses Durham Window Pros
- ✓We identify the wall before we name a product. A punched opening in a brick bearing wall takes a different unit, a different anchor and a different water detail than a stud wall, and the quote says which one you have.
- ✓North Carolina exempts window and door replacement from the building permit below forty thousand dollars, which means no inspector ever looks at it. We put the flashing sequence and the anchor spacing in the written proposal so there is a record.
- ✓Openings are measured at head, centre and sill and checked on both diagonals. In converted mill and warehouse buildings the difference across one opening is routinely more than the tolerance a stock unit allows for.
- ✓We quote laminated glass for noise and forced entry rather than impact packages for a debris region Durham is not in. If you want the acoustic benefit we will price the interlayer; we will not price a hazard you do not have.
