FD90 window · FDTL140 sliding door set
Full-FRP systems for cold-region projects.
This category contains two full-FRP systems. FD90 covers casement and tilt-and-turn window units; FDTL140 covers large sliding door sets with leaf compression at closing. Each project is checked against the cited certificate or catalogue configuration.

Full-FRPProfile construction
A category with a clear boundary.
The grouping is based on profile construction and documented cold-region data. PD75 and PD95 use aluminium-composite sections and therefore remain in a separate category.
Full-FRP construction
Both systems use pultruded glass-fibre composite profiles for the frame construction rather than aluminium shells connected by a composite insulating core.
Cold-climate qualification
FD90 adds PHI component certification at phB for the cool, temperate climate zone; both systems retain project-specific verification of glass, seals, hardware, joints and installation.
Cold-climate category
Two systems in the category.
Choose by opening type and leaf size: FD90 for casement and tilt-and-turn windows, or FDTL140 for compression-seal sliding doors.

Category comparison.
The comparison separates the supplied 2026 catalogue values from FD90's PHI certificate. Every thermal value remains tied to its identified configuration rather than serving as a universal project guarantee.

Category inclusion does not replace project qualification. Final thermal, structural, air, water, acoustic and durability claims must be confirmed for the ordered size, glazing, hardware, joints and installation method.
