  3. Lots of design possibilities regarding the shapes – from rectangles, trapezoids, arches, circles and other non-standard shapes.
  4. Great parameters in energy efficiency and sound insulation.
  5. High safety level guaranteed by the stability of aluminum profile  combined with high-quality Maco fittings.
  6. Easy for upkeep and care, thanks to the external aluminum profile. 
Technical data
PROFILE Possibility to choose between profiles with three installation depths: 68mm, 78mm, 88 mm in three types of wood: three- or four-layer solid square timber: meranti 450+, pine and larch, with aluminum clad on the outside.
GLASS Glass – Two-glass package with 24 mm thickness in standard, with thermal transmittance coefficient Ug = 1,0 W/(m2K) according to the PN-EN674 norm; the possibility to apply two-, three- or four-glass packages. For Duoline 68 mm – max. glass package thickness is 42 mm with thermal transmittance coefficient - Ug = 0,6 W/(m2K). For Duoline 78 mm – max. glass package thickness is 48 mm with thermal transmittance coefficient - Ug = 0,5 W/(m2K). For Duoline 88 mm – max. glass package thickness is 50 mm with thermal transmittance coefficient - Ug = 0,5 W/(m2K) with three-glass package and Ug = 0,3 W/(m2K) with four-glass package with krypton. The possibility to apply glass with enhanced sound insulation, tempered, safety, anti-burglary, ornament or solar protective.
