MITEK Roof Trusses Sets

Certified prefabricated MITEK roof truss sets. A trussed rafter roof is a fully engineered structure delivering a practical and versatile roofing solution. Manufactured offsite in factory-controlled conditions, roof trusses offer immense versatility.A wide variety of truss configurations allows for a huge range of different applications, such as:● Room-in-the-roof (attic) trusses● Raised ceiling trusses● Scissor trusses
Trussed rafters can be manufactured in various timber section sizes, with larger sections allowing for big spans, making them ideal for both residential and commercial applications.

Prefabricated roof panels

● U-Value: 0.15-0.09 W/m²K (optional)● Panels for gable, flat, or monopitch roofs● Pre-installed battens and counter-battens for roof tiles (optional)● Underlay membrane (optional STEICO boards)● Vapor barrier pre-installed or delivered separately● Fast installation process

Variety of Construction Elements

At B2B PREFAB, we go far beyond standard solutions. With a flexible design approach and access to multiple partner factories in Ukraine, Slovenia, and other parts of Europe, we can engineer and manufacture a wide range of construction elements tailored to any architectural concept, technical requirement, or climatic condition.
We produce:
● Exterior wall panels in various thicknesses, configurations, and cladding options — from economical systems to passive house standards.● Interior walls, both load-bearing and non-load-bearing, with customized sound insulation or fire resistance.● Facade panels with integrated windows, doors, niches, or decorative elements.● Floor structures, lightweight or heavy-duty, for residential and industrial applications.● Roof trusses of any configuration: gable, hip, folded, with attic space, overhangs, or prepared for solar panel installation.● Preassembled modules or volumetric units, such as factory-built bathrooms, kitchens, or technical rooms.● Window and door units, precisely integrated into wall panels at the factory.● Raffstore systems, roller shutters, and sun protection solutions, fully pre-installed into panels for easy on-site operation.● Architectural details such as porches, bay windows, terraces, or balconies — all designed in harmony with the main structure.● We work with both standard series and fully custom orders. Using modern BIM-based design and automated production lines, we ensure precision, efficiency, and flexibility in every project
