Durham Picture, Transom and Arch-Top Architectural Glass — Residential & Commercial

Durham Window Pros provides professional picture, transom and arch-top architectural glass in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. Nothing buys daylight per dollar like a fixed lite, and nothing is less forgiving to set. There is no hardware and no weatherseal to wear out, so the entire burden of the job lands on the opening, the setting blocks and the perimeter joint.

Durham's industrial stock is full of openings that want exactly this. Warehouse and mill walls were pierced for light, and many of the heads are segmental arches turned in brick rather than flat lintels. A square unit under a curved head throws the elevation off immediately, and it is the single most common thing we are asked to correct on a previous contractor's work.

So we template. A radius or segmental head is measured off the actual masonry with a rise-and-span template rather than ordered from a nominal size, because a hand-laid arch from 1902 is not the arc a catalogue assumes. The unit comes back matching the brick, and the perimeter joint stays a consistent width all the way round instead of tapering.

Transoms are the other Durham fixture, above shop doors on the ground floors of converted buildings and above interior openings on the floors above. Original transoms were often operable on a chain; most are painted shut. We will fit a fixed insulated unit that keeps the divided-lite pattern, or restore the pivot if the hardware is still there and the frame is sound.

Large fixed lites bring their own physics. Glass has weight and thermal stress, and a big unit in a dark frame on a west wall in a Durham July is a genuine thermal load. We size the glass thickness to the span rather than defaulting, set it on proper setting blocks at the quarter points, and specify heat-strengthened glass where the pattern of shade across the lite will be uneven.

Safety glazing is not optional and is easy to get wrong. Any lite over 9 square feet with its bottom edge less than 18 inches above the floor, its top edge more than 36 inches above the floor, and a walking surface within 36 inches of it is a hazardous location and must be tempered or laminated. A lot of picture windows land squarely in that description.

Where the opening is genuinely large we combine: a fixed centre lite with an awning below or casements at the flanks, on a common frame with a structural mullion. You get the glass area and the sightline of the original, plus ventilation and a code-compliant escape opening if the room needs one. That combination is what we specify on most tall mill openings.

The honest limitation of fixed glass is that it does nothing but sit there. It will not ventilate, it will not serve as egress, and it cannot be opened to clean the outside face on an upper storey. Plan the operable units around it first and buy the picture unit last, rather than the other way round.

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.

What We Handle

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.
