UW- value 1.1

REHAU Brillant-Design 80 is a high-quality PVC profile system for windows and doors, designed to provide an increased level of thermal insulation, sound insulation and individual design. With an installation depth of 80 mm and six chambers in the profile, this system provides very good thermal insulation, contributing to a significant reduction in energy consumption for heating. Windows made from Brillant-Design 80 profile also effectively absorb external noise, creating a calm and quiet atmosphere in the room.

The system is characterized by high strength and resistance to weather conditions, guaranteeing durability and stability of the structure. The surface of the profiles is smooth and easy to maintain. REHAU Brillant-Design 80 offers expanded design possibilities thanks to the variety of shapes, colors and decorative coatings, allowing the creation of elegant and harmonious solutions suitable for the most demanding architectural projects, including both modern construction and reconstruction.

System Design Parameters:

  • Installation depth: 80 mm (Frame). This is an extended version of the system for those seeking a compromise between classic design and maximum heat retention.
  • Profile construction: 6 air chambers. The additional chamber and increased profile width create a powerful barrier against cold.
  • Design: Exclusive rounded design of sashes and frames. The profile has pronounced curves (20 mm radius) on visible front surfaces, distinguishing it from the strict "angular" forms of standard windows.
  • Surface: HDF (High Definition Finishing) — Rehau's benchmark glossy surface. Distinguished by minimal porosity (dirt doesn't penetrate) and radiant shine.
  • Sealing: Two sealing circuits (seal overlap: 8 mm inside, 7 mm outside). High-elasticity EPDM seals are used, maintaining properties at extreme temperatures.

Glazing Options:

  • Maximum glass unit thickness: up to 41 mm.
  • Infill type: Ideally suited for installation of energy-efficient double-chamber glass units with inert gas fill (argon/krypton).
  • Glazing bead installation: Ability to use rounded designer glazing beads that follow the profile geometry.

Certified Characteristics (according to DIN EN 14351-1):

  • Profile thermal insulation (Uf): 0.99 W/m²K. Thanks to the 6-chamber construction and 80 mm depth, the profile surpasses the psychological thermal conductivity mark of 1.0, approaching passive heating system standards.
  • Window thermal insulation (Uw): Can reach 0.9 W/m²K and below (depending on glass unit).
  • Sound insulation (Rw,p): up to 45 dB (noise protection class 5).
  • Burglary resistance: up to RC3 class (with anti-burglary hardware).
  • Air permeability: Class 4 (maximum airtightness).
  • Rain resistance: Class 9A.
