  • Wooden profiles available in three depth options.
  • Minimal maintenance and extended timber life due to the external aluminium profile.
  • High quality is achieved through timber lamination and durable aluminium profiles ensuring structural stability.
  • Huge selection of colours for the interior and exterior from both aluminium and wood colour ranges.
  • Special ecological water-based varnishes with a primer to protect against pests and fungus.
  • Considerable thermal parameters due to top quality materials and special sealing systems.
  • Considerable safety level guaranteed by two anti-burglary bolts as standard.
