Ask for the current section drawings and component mapping for CP001–CP005. The codes alone do not confirm a mating profile set.

140 mm frame · Sliding door
Side-pressure sealing for sliding doors. Confirm the panel arrangement, hardware and threshold for your opening.
Catalog opening references: Sliding with side-pressure compression seal. Review the proposed size and hardware before ordering.
*Configuration-dependent catalog information, not an approved operating limit. Confirm the drawing, hardware, glazing and verification scope.
CP006–CP011 identify the compression-seal series. Confirm current assembly drawings; a historical lift-sliding test report does not automatically cover this system.
Discuss a profile sampleReinforcement 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

Choose system profiles when you will fabricate locally. Choose finished units when you need an agreed assembly built to a window schedule. Glass, hardware, accessories, machining, packing and delivery are defined in the quotation.
Lineals are the pultruded profile lengths used to make the window frame, sash, mullion and other constant-section components. A compatible set of lineals and accessories is cut, joined, glazed and fitted with hardware to form a finished window.
The catalog covers 50, 55, 60, 65, 70, 80 and 90 casement systems, a distinct 90 sliding system, and the 140 compression-seal sliding door. Review the current section drawings, opening configuration and supply availability before ordering.
The current 140 range is a compression-seal (side-pressure) sliding door system, with section references CP006–CP011. The historical Intertek lift-sliding report retains its original specimen name. Its results do not automatically apply to the current compression-seal configuration.
No. Uf describes the frame, Ug the glazing and Uw the whole window. Window size, frame, glass, spacer and assembly affect the result. The 90-series PHI certificate covers its stated configuration, not every unit assembled from FRP profiles.
Start with your role, destination, intended opening or application and expected quantity if known. Choose technical selection, budget pricing or sample evaluation. We can clarify the section list or window schedule before a formal quote.
For profiles, review the section, lengths, material, finish, quantity, tooling and machining. For finished units, review each opening, glass and hardware configuration. Packing, transport, testing, sample fees, production quantity and lead time are confirmed for the order; a catalog listing is not a stock promise.
Agree installation information, local labor, unloading, spare parts and after-sales responsibilities in the supply scope. Warranty terms depend on the contracted product and configuration. Shipping complete units does not by itself include on-site installation.
Send a drawing, a section list or a window schedule, and the destination. Early technical and sample inquiries are welcome. We reply within one business day; a formal quotation follows once the specification and delivery are reviewed.
