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.

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

  2. 02MullionDivides the frame into lights and carries wind load from head to sill.
  3. 03SashThe opening leaf: it carries its own glazing and moves on the hardware.
  4. 04HardwareHinges, handles, locks and restrictors, set in the profile's hardware groove.
  5. 05Seals and beadsGaskets seal the sash to the frame; glazing beads hold the glass in its pocket.
  6. 06GlazingThe insulated glass unit, set in the glazing pocket of the frame or sash.

Reinforcement or a subframe? A reinforcement stiffens a frame of another material; a subframe connects the window to its opening. Neither replaces the primary frame set. Window reinforcement

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. Design, tooling, first articles and validation are agreed as separate stages.

Request a drawing review

Choose a sample for the decision you need to make

Each sample answers a different question, from section geometry to production consistency.

  1. Sample 1

    Short section

    Check section geometry, surface and color.

  2. Sample 2

    Corner sample

    Review the joint, glazing pocket and mating parts.

  3. Sample 3

    Sample window

    Trial assembly and the agreed performance checks.

  4. 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 and installation profiles

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

  • 75 x 25 Subframe
  • 75 x 50 Subframe

How profile procurement works

At each stage, agree the information to supply, the next review and the confirmation needed to proceed.

  1. Step 1

    Define the application

    You provide: Market, opening types, fabrication capability and demand.

    We review and return: A proposed system or drawing-led development route.

    Confirmation point: Agree the buying route.

  2. Step 2

    Review the profile set

    You provide: Series or drawings, glass pocket, seals and hardware interfaces.

    We review and return: Mating sections and a clear accessory and machining scope.

    Confirmation point: Confirm compatibility and drawing revisions.

  3. Step 3

    Scope the quotation

    You provide: Quantity per section, lengths, finish and delivery destination.

    We review and return: Separate profile, tooling, sample, accessory, packing and freight items.

    Confirmation point: Agree what the quotation includes.

  4. Step 4

    Evaluate samples

    You provide: Critical dimensions, finish and the purpose of the sample.

    We review and return: The agreed short sections, corner sample or first articles.

    Confirmation point: Record sample approval and any changes.

  5. Step 5

    Fabricate & validate

    You provide: Your joining, glazing, drainage and hardware arrangement.

    We review and return: Technical clarifications and the agreed sample-window validation plan.

    Confirmation point: Confirm assembly and acceptance requirements.

  6. Step 6

    Release production

    You provide: Approved specifications, order quantities and packing requirements.

    We review and return: The agreed production, inspection, identification and shipping documents.

    Confirmation point: Accept the first batch before scaling.

  7. Step 7

    Plan repeat supply

    You provide: Replenishment demand, batch feedback and engineering changes.

    We review and return: Repeat-order planning against controlled section and finish versions.

    Confirmation point: Review changes before mixing components.

A section list starts the conversation

List each profile by series, section code and drawing revision. Add length, quantity and units, then describe accessories and fabrication work.

Evidence that matches your specification

The window catalog provides series and assembly context; the material data sheet describes the identified laminate. A certificate or report for a finished specimen does not automatically certify a lineal or a locally assembled window. Agree the supporting documents and any required validation with the fabricator.

Packing and delivery

FIG. 5 Profile bundleSchematic · not to scale
Packing concept. The packing design is agreed for each order.

Plan around length and finish

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

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

Purchasing 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.
