| Spec | Options |
| Thickness | 1/4in (6mm) monolithic tempered; 3/8in (10mm) and 1/2in (12mm) tempered for large lites and all-glass entrances; 3/4in (19mm) tempered for frameless door leaves; 1in (25mm) overall insulated units (typically 1/4in – 1/2in air or argon space – 1/4in); laminated 1/4in (6mm) and up; laminated-insulated 1in (25mm) overall |
| Glass type | Tempered, laminated, laminated-insulated, insulated (with or without low-E), clear, low-iron, tinted (bronze, grey, blue-green), spandrel, obscure |
| Maximum span | Set by system depth, glass thickness, opening height and design wind pressure not by a single number. As a working guide: a 1-3/4in x 4-1/2in section with 1/4in tempered handles ordinary retail bay widths; taller or wider lites step up to 3/8in or 1/2in glass, or to the 2in x 4-1/2in section, or add an intermediate horizontal. Exposed coastal frontage raises the design pressure and can force the heavier section. Every opening gets calculated for its actual size and exposure |
| Edge profile | Not applicable to framed lites edges are captured by the frame and stops. All-glass entrances and frameless sidelites get a flat-polished or seamed edge, with all holes, notches and patch cut-outs fabricated before tempering |
| Hardware finish | Clear anodized, bronze anodized (dark and medium), black anodized, and Kynar (PVDF) paint in custom colors. Kynar is the right call on a salt-air frontage it holds color and resists coastal weathering better than paint systems that are not fluoropolymer-based. Door hardware in matching or contrasting finishes |
| Framing depth | 1-3/4in x 4-1/2in or 2in x 4-1/2in. Deeper sections available where the opening demands it |
| Set position | Center-set, front-set, offset-set |
| Thermal | Non-thermal or thermally broken (polyamide strut or poured-and-debridged) |
| Doors | Narrow, medium and wide stile aluminum doors; all-glass doors on patch fittings; single or pairs; with or without transoms and sidelites |
| Door hardware | ADA-compliant lever or push/pull hardware operable without tight grasping, pinching or twisting of the wrist; surface or concealed overhead closers with adjustable closing and latching speed; floor closers on all-glass doors; panic/exit devices where required; electric strikes and access control |
| Safety glazing | Tempered or laminated required in doors, in the fixed panels adjacent to doors (sidelites), and in other hazardous locations, under IBC/IRC safety glazing requirements. Your Cape Cod or Barnstable County building official has the final say on which openings qualify |
| Egress and marking | Exit doors must remain openable from the inside without a key, tool or special knowledge. Where required, exit and egress signage and glazing markings go on the drawing before fabrication. Confirm the requirement with the local official and the fire department |
