FRP window & door system profiles

F1 Composite supplies FRP window and door profiles, also called fiberglass lineals or GRP profiles, for local fabrication. This route covers the profile set and agreed accessories; cutting, joining, glazing and final assembly are defined with the fabricator.

Build locally with a compatible system

A profile set your factory can evaluate

Select a compatible profile set before choosing individual sections. Frame and sash interfaces, gasket grooves, glazing beads, drainage and hardware locations must work together. A profile from one series is not automatically interchangeable with another.

Who buys this: Window and door manufacturers, fabricators and OEM development teams
Supply scope: Frame, sash, mullion, transom, sill and other agreed constant-section profiles

System selection

Compare nine window & door systems

Start with the opening you need, then review the matching profile set. The 90 casement and 90 sliding systems are distinct; the 140 series uses compression-seal sliding operation.

9 systems shown. Compare up to three; open a card for sections and supply details.

Component map · schematic, not a fabrication drawing. The selected system defines the actual interfaces.

Specify a compatible set

Frame, sash and mullion sections work with the glazing beads, gaskets, connectors and operating hardware. Confirm the mating interfaces before choosing individual lineals.

Profile supply: Identify the sections, cut lengths and any agreed accessories. Define who cuts, joins, glazes and assembles.
Finished-unit supply: Agree the complete configuration, window dimensions, factory work and installation interface.
Looking for reinforcement or a subframe?: A reinforcement supports another frame material. A subframe connects the window to its opening. Neither is interchangeable with the primary frame set.

Choose your starting point

From fabrication to repeat supply

01Window manufacturers & fabricatorsCan we build this system on our own production line?

Select a system → review interfaces → inspect samples → trial fabrication → validate a sample window → first batch

You share: Your current frame materials and equipment, target opening types, market and expected volume.
We review with you: A proposed profile set, accessory scope and an agreed sample and fabrication review.
Before moving ahead: Confirm cutting, corner joining, drainage, glazing and hardware interfaces before releasing a production order.

Discuss local fabrication →

01System brands & OEM teamsShould we adopt a system or develop our own section?

Define interfaces → engineering review → tooling scope → approved drawing → first article → trial assembly → production release

You share: Section drawings or a concept, critical interfaces, tolerances, design targets and forecast demand.
We review with you: A development scope separating tooling, samples, profile supply, machining and validation.
Before moving ahead: Agree drawing ownership, tooling arrangements, acceptance criteria and change control.

Review my system design →

01Profile distributorsWhich compatible sections should we stock together?

Define local demand → choose a system mix → review samples → plan the first order → support fabricators → replenish

You share: Your downstream customers, preferred lengths and colors, anticipated mix and delivery destination.
We review with you: A coordinated frame, sash and mullion supply proposal with packing and repeat-order requirements.
Before moving ahead: Confirm quantities by section and finish; a catalog series does not establish live inventory or a minimum run.

Plan profile supply →

02Architects & facade consultantsWhat can we specify, and which evidence applies?

Explore systems → review sections & details → match performance evidence → discuss the specification → hand over to procurement

You share: Design intent, opening and wall details, performance targets and the project location. Quantities can follow later.
We review with you: Available system information and the scope of documents relevant to the proposed assembly.
Before moving ahead: Distinguish material data, a tested window configuration and the requirements of the installed project.

Agree the complete supply boundary

Use the scope below when comparing quotations. Availability, quantities, lead time and support are confirmed for the selected specification.

Profile and finished-window quotation scope
Supply item	Profiles for local fabrication
FRP frame, sash and mullion sections	Selected sections and lengths
Glazing beads, gaskets and connectors	List each supplied or locally sourced component
Glass and operating hardware	Separate unless explicitly included
Cutting, machining and assembly	Local fabrication or separately agreed work
Evidence and inspection	Material, dimensions and agreed batch records
Packing, freight and unloading	Confirm lengths, protection and destination
Site installation and after-sales	Fabricator responsibility and agreed support

Adopt an existing system

Review the current sections, gasket grooves, joining method, glazing and hardware interfaces. Evaluate samples and your fabrication sequence before releasing a production order.

Evaluate a system sample →

Develop a custom profile

Provide a drawing or concept with critical dimensions, material and finish needs, tolerances and expected demand. Agree design, tooling, first articles and validation as separate stages.

Request a drawing review →

Choose a sample for the decision you need to make

SAMPLE 1

Short section

Check section geometry, surface and color.

SAMPLE 2

Corner sample

Review the joint, glazing pocket and mating parts.

SAMPLE 3

Sample window

Trial assembly and the agreed performance checks.

SAMPLE 4

First batch

Confirm production consistency and receiving checks.

Sample types shown schematically. A short-section approval does not establish finished-window performance. Agree availability, sample fees, test scope and delivery before ordering.

Subframes & installation profiles

Review the connection between the main frame and the building opening. Confirm the cross-section, fixing and wall interface against current drawings.

65 x 24 Subframe
75 x 25 Subframe
75 x 50 Subframe
90 x 25 Subframe
90 x 50 Subframe

Catalog size designations. Confirm dimensions, units and tolerances on the approved drawing.

Quantity: State metres / pieces
Finish: Color and surface
Scope: Profiles + listed accessories

Illustrative format only. Unspecified information can be clarified during review; this is not a production schedule.

Evidence that matches your specification

Evidence 1

Material & section information

Review the identified material system, dimensions and drawing revision. Confirm whether values are typical references or order-specific acceptance criteria.

Evidence 2

Window configuration evidence

Uf is the frame, Ug the glazing and Uw the complete window. The PHI 90-series certificate covers its stated component configuration; it does not certify every size or series.

Review document scope →

Evidence 3

Project & installation requirements

Share the destination, project specification and wall interface. Match the offered configuration and installation responsibilities before approving production.

Packing concept · confirm the order-specific design

Packing & delivery

Plan around length and finish

Agree bundle length, supports, surface protection, section labels and handling requirements. Separate profiles by series, code and finish so the receiving fabricator can identify the complete set.

Confirm packing, freight and delivery terms in the quotation; catalog lengths are not a freight booking.

Purchasing questions

Frequently Asked Questions

Does profile supply include complete windows?

No. This purchasing route is for lineals and agreed components. Glass, hardware, gaskets, machining and assembly must be listed in the quotation. Use the finished window and door route when you need factory-assembled units.

Can F1 develop a new window profile?

A new section can be reviewed through the custom pultrusion process. Provide the geometry, interfaces, material requirements, tolerances and annual demand so tooling and sample development can be scoped.

Are reinforcement profiles the same as FRP frames?

No. Reinforcement sections support a separate frame system, while primary FRP frame and sash profiles form the window structure. Identify the role and mating section before requesting a quote.
