The new MB-86 window and door series have been designed to offer outstanding insulation properties. It meets the increasing requirements from the legislative and general market demands for the enhanced energy saving construction of new windows and doors. Offered in three varieties ST, SIand AERO it is the first aluminum system to employ silica aerogel, the nanoporous material that 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 give rise to low values of thermal conductivity. Therefore the system features the industry leading thermal performance. In addition it also features exceptional rate of profiles inertia that allows for greater windows in size and weight. 

Features and benefits:

• large selection of profiles
• newly shaped, extra thick thermal breaks
• multi component central gasket
• glazing strips with additional sealing option
• glazing up to 67,5 mm enabling all types of two chamber glazing, acoustic and security, anti burglary glazing
• large, wire-free glass areas
• appropriate for variety of hardware including concealed hinges
• water draining available in both traditional and concealed options
• highly energy efficient from 0,57 W/m²K
• clean, sharp lines of narrow extruded aluminum framing
• multitude of finish options
