Frame & sash construction
Multi-chamber UPVC profiles use internal chambers to interrupt heat flow. Corners are precision mitered and fusion welded; selected profiles can be foam injected.

Configure 7/8" double-pane or 1 3/8" triple-pane units with warm-edge spacer, argon fill and project-appropriate Low-E coatings.
Casement and awning units use compression sealing and multi-point locking; sliding/hung units use weatherseals, tracks and cam-style locking.
Tempered glass is heat treated for safer breakage. Laminated security glass bonds glass to an interlayer that helps retain fragments after impact.

The product is more than a slab: insulated steel or fiberglass door, jamb, weatherseal, sill/threshold, hinges, lock preparation and optional sidelites/transoms.
Clear, privacy and decorative insulated glass packages can be combined with tempered or laminated safety/security glazing as applicable.
Standard deadbolt preparation or multi-point locking can pull the slab tightly into the perimeter weatherseal for security and air sealing.

Interior doors can be selected by core construction, panel/profile, slab vs pre-hung format, jamb depth, handing and finish.
A pre-hung interior package pairs the slab with hinges and a factory-prepared jamb so the assembly is installed as a system.

Large insulated glass panels ride on rollers in a multi-track frame and sill; screen, locking handle, panel count and glass package are configurable.
Patio-door glass packages can use Low-E, argon and upgraded safety/security glazing depending on product availability and code requirements.

Horizontal sections use formed skins around an insulated core with hinged joints, perimeter seals and track/spring hardware.
Top-section or full-view glazing can be specified where available, including safety glazing where required.
