Images illustrate catalogue configurations. Final opening layout, dimensions, finish and hardware are confirmed for each project. Series numbers are product identifiers.

Composite profiles, configured as a complete unit

Glass reinforcement and a thermoset polyurethane matrix form the pultruded frame profiles. Glazing, seals and hardware are selected with the complete assembly.

FIG. 2 Composite profile sectionSchematic · not to scale

Illustrative section detail. Geometry and components vary by system.

Frame and glazing together

Match the chosen series to the opening size, insulating glass build-up, spacer and target whole-window U-value.

Opening, seals and hardware

Specify how each sash or door leaf operates, its handing, locks, handles and perimeter seals. Review the proposed size and glass weight together.

Finish and installation interface

Confirm interior and exterior colors on physical samples. Provide sill, jamb and head details, fixing requirements and drainage interfaces.

Specify the performance of the complete assembly

The product tables reproduce the catalogue configurations. Select the glass, frame, size and operating hardware before confirming performance for your project.

Whole-window U-value

Uw describes the complete window; Ug describes the glass and Uf the frame. The window and door tables use W/(m²·K). Material conductivity is a different property.

Glazing build-up and warm edge

Low-e identifies a coated glass layer. A/Ar notation and warm-edge options are retained as listed. Confirm cavity fill, spacer, coating surfaces and safety-glass requirements.

Paired values need configuration confirmation

A pair such as 0.8 / 0.7 is reproduced as listed. Its individual conditions are not defined in the reference data; it is not assigned to air/argon fill or treated as a performance range.

Classes and acoustic values

Wind, water and air entries are catalogue classes with no stated test standard. Acoustic values retain the stated > symbol; no Rw, STC, OITC or international class conversion is implied.

Agree what your finished-unit quote includes

A quotation identifies the frame, glass, hardware, seals and accessories for each opening. Confirm installation materials, site labor, spare parts and delivery terms as part of the agreed scope.

Plan delivery around your openings

FIG. 3 Window crateSchematic · not to scale

Packing concept. The packing design is agreed for each order.

Plan around each opening and crate

Agree glass protection, crate size and weight, window-to-crate labels, unloading equipment and delivery phases. Check for damage at receipt and keep the window IDs with the installation schedule.

Port delivery, site delivery, unloading and installation are separate scopes. Confirm the local installation team and spare parts before ordering.

Finished window and door questions

Which finished window and door systems can I compare?

The finished-unit catalog covers 65, 72, 83 flush, 85, 95, 103 tilt-and-turn, 103 micro-vent and 114 curtain-wall-style windows, plus an insulated entrance door, 132 lift-and-slide door and 145 side-pressure door. Series numbers are product identifiers; confirm dimensions on the selected drawing.

Are these the same systems as the profile-supply catalog?

The finished-unit range has its own configurations and catalog. A matching number such as 65 does not establish interchangeability with a profile-supply series. Specify the purchasing route and full product name; confirm drawings, interfaces and scope for the proposed assembly.

What is included in a finished-unit quotation?

The quotation identifies the frame, glass, hardware, seals and agreed accessories, together with inspection, packing and delivery terms. Confirm installation materials, site labor and spare parts separately rather than assuming they are included.

Can one U-value be applied to every window size?

No. Whole-window performance changes with frame geometry, window size, glazing and edge details. Request data for the proposed assembly and distinguish whole-window Uw from glass Ug and frame Uf.

What should I send before requesting a price?

Start with the opening schedule, project location, required performance, glazing and hardware preferences. Drawings and quantities allow the unit configuration and documentation requirements to be reviewed before a formal quote.

What do paired U-values and performance classes mean?

The tables retain the catalogue U-value pairs, but the conditions for each value are not defined in the reference data. Wind, water and air classes have no stated test standard, and the sound figures have no stated Rw or STC method. Request configuration-specific documentation before using them as project acceptance criteria.

Bring us your window and door schedule

Share the selected series, opening schedule, glazing and hardware preferences, and project destination. We will clarify any undecided configuration details. We reply within one business day; a formal quotation follows once the specification and delivery are reviewed.
