MB-86N SI
hermally Insulated Aluminum Window System
Advanced Performance. Architectural Freedom. Sustainable Design.
The MB-86N is a premium aluminum window system designed for exterior architectural applications that demand exceptional thermal insulation, structural strength, and airtightness. It is ideal for both high-performance residential and commercial buildings, offering a perfect balance between energy efficiency and modern aesthetics.
Key Features:
- Three-chamber aluminum profiles with thermal breaks, offering structural depths of 3 1/16″ (frame) and 3 3/8″ (sash).
- Available in two thermal variants:
- MB-86N ST – standard insulation
- MB-86N SI – superior insulation with EPS inserts
- Thermal breaks up to 1 11/16″ wide, made of fiberglass-reinforced polyamide.
- Advanced sealing system with two-component EPDM gaskets and optional vulcanized frames for maximum airtightness.
- Glazing range: up to 2 3/4″ in operable sashes, allowing for triple glazing, acoustic, or burglar-resistant glass.

BENEFITS
At Fabrik, we empower our customers to shape the future. Our Motor Steel is a specialized cold-rolled sheet product meticulously engineered to optimize the performance of electromagnetic core materials in electrical equipment components. These steels are designed to minimize energy losses, ensuring efficient utilization of electrical energy input into motors.
FEATURES
Our motor lamination sheets are meticulously cold-rolled below their recrystallization temperature, offering precise control over product shape, thickness, dimensions, and surface finish. We produce a variety of steel grades, with each grade primarily differentiated by its specific Core Loss requirement. These grades are provided in a semi-processed, unannealed state and must undergo annealing after punching the laminations to unlock their optimal magnetic properties.
BENEFITS
Home appliances are more than an essential part of our homes. They’re an essential part of life. VITRENEMEL Steel optimize the application of porcelain or vitreous enamel coatings and are manufactured with specialized properties that can achieve both good formability and enhanced aesthetics. Our steel products are cold rolled, producing a high quality finished surface to exceed our customers’ requirements.
FEATURES
Fabrik Steel produces three grades of steel that optimize the application of porcelain (or vitreous) enamel coatings that resist fish-scaling during the enameling process, resist carbon boil during enameling, and provide the sag resistance needed during the firing process.
All VITRENEMEL grades typically are furnished with a rough matte finish to improve adhesion of the enamel coating. The approximate surface roughness is 55 to 90 micro-inches. A rougher surface finish, 90 to 150 micro-inches, can be provided if required for a specific application.
The dimensional tolerances for VITRENEMEL Steel Sheet products are the same as those for Cold Rolled Steel Sheet as established by ASTM.
BENEFITS
Cold-rolled full hard unprocessed sheet by Fabrik Steel is the option to choose for applications that require very limited bending and/or roll-forming.Supplied directly from the cold-reduction mill without any annealing to soften the steel, our full hard sheet is highly work-hardened and exhibits a high resistance to denting, with only minimal ductility. The hardness is Rockwell B 84 minimum.
FEATURES
Since the product is supplied directly after cold rolling without further processing, our full hard cold-rolled unprocessed sheet is not subject to the same product standards that have been established for other cold-rolled sheet products.We provide it with a matte or smooth surface finish produced on the cold reduction mill.
