MB-86 ST, MB-86 SI, MB-86 SI+ And MB-86 Aero Doors

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

Offered in three varieties: 'ST', 'SI' and 'AERO', and incorporates 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, a high rate of profile inertia capability allows for greater construction in size and weight.

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 58.5 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 3.
  • Wind load resistance to PN-EN 12210:2001: Class C1/ B2.
  • Watertightness to PN-EN 12208:2001: Class 5A (200 Pa).
  • Thermal insulation (Uf): MB-86 ST od 2.16 W/(m²K), MB-86 SI od 1.76 W/(m²K), MB-86 SI+ od 1.49 W/(m²K) and MB-86 AERO od 1.22 W/(m²K).
