MB-86 ST, MB-86 SI And MB-86 Aero Windows

The new MB-86 window and door series have been designed to offer high insulation properties.

Offered in three varieties: 'ST', 'SI' and 'AERO', and incorporating silica aerogel. The nonporous material has a very high proportion of free void volume, compared to conventional solid materials. Its high pore volume, low solid content and torturous path amorphous structure offer low values of thermal conductivity.

In addition, it also features an exceptional rate of profile inertia that allows for greater construction in size and weight. A version with concealed sash (MB-86US) is also available.

Features and benefits:

  • Large selection of profiles available.
  • Newly shaped, extra-thick thermal breaks.
  • Multi-component central gasket.
  • Glazing strips with an additional sealing option.
  • Glazing of up to 67.5 mm, enabling all types of three-chamber glazing, acoustic and security, and anti-burglary glazing.
  • Large, wire-free glass areas.
  • Appropriate for a variety of hardware, including concealed hinges.
  • Water draining available in both traditional and concealed options.
  • Highly energy efficient from 0.5 W/(m²K).
  • Clean, sharp lines of narrow extruded aluminium framing.
  • Various finishes available.


  • Air permeability to PN-EN 12207:2001: Class 4.
  • Wind load resistance to PN-EN 12210:2001: Class C5.
  • Watertightness to PN-EN 12208:2001: Class E1500.
  • Thermal insulation (Uf): MB-86 ST od 1039 W/(m²K), MB-86 SI od 0.92 W/(m²K) and MB-86 AERO od 0.57 W/(m²K).
