Slimmest steel profiles with thermal break

Innovations in the slender systems, heat-insulated steel profile system RP-ISO-FINELINE were introduced at BAU 2019 in Munich. In addition to the heat-insulated door, window, and partition wall systems, tilt and turn applications especially in single-sash and double-sash windows, and whole glass locked doors were presented to the visitors at the RP Technik stand.

RP Fineline offers, extremely slim steel profile systems that have thermally insulating solutions for windows, doors and fixed glazings are primarily preferred for modern constructions with the greatest possible transparency and the preservation, restoration and reconstruction of historic buildings and listed industrial buildings.

Elegance and Design Freedom

 Minimum visible height and wide openings in windows, doors and partition walls – Base width 70 mm – Different window types and opening variations – Glass thickness up to 50 mm – Various glazing bead contours – Classic to modern hardware options – Hidden water drainage solution – High corrosion resistance with special galvanization technique


- Thermal Insulation: Uw ≥ 0,89 W/m²K

- Air permeability: ≤4

- Wind load: ≤C5 / B5

– Watertightness: ≤E900

– Sound insulation: ≤ 50 dB
