The PBI 50N system is designed for partitions and constructions that do not require thermal insulation, suitable for both interior and exterior applications such as doors—including swing doors—windows—including pass-through windows—non-load-bearing partition walls, display windows, and booths.
With a profile depth of 50mm, it is one of the strongest profiles in this category on the market.
Based on the PBI 50N system, smoke-tight doors and walls can also be constructed. The smoke-tight properties of doors in the PBI 50N and PBI 40E systems have been certified under a common approval.
Building elements made from the PBI 50N system are intended for use in residential, public, and industrial buildings as internal partitions.
Doors and walls in the PBI 50N system can also be used as external partitions only in cases where thermal insulation or watertightness is not required, and static calculations account for wind loads.
Technical Description
The PBI 50N system consists of single-chamber aluminum profiles without thermal insulation, with a characteristic depth of 50mm. Door frames and leaves are 50mm, and window leaves are 57mm. Various types of transparent and opaque infills with thicknesses from 4 to 45mm can be used.
Maximum construction dimensions achievable with this system:
- HxW = 2400mm x 1200mm for single-leaf doors, or HxW = 2300mm x 1300mm for single-leaf doors
- HxW = 2400mm x 2210mm for double-leaf doors, or HxW = 2300mm x 2600mm for double-leaf doors
Where:
H – door height in clear opening
W – door width in clear opening
Additional Benefits
The system incorporates technological solutions transferred from the previously introduced “warm” PI 50N system with rebated hinges. Accessories and fittings are standardized across these systems. This unification allows for faster construction and reduces the risk of errors during prefabrication. The aesthetic value of constructions is enhanced by high-quality surface finishing: powder coating and anodizing. Products can be painted in any RAL color.
Key Features
The PBI 50N system enables the creation of doors—including swing doors—windows—including pass-through windows—partition walls, and cash partition walls. Constructions can be made in various configurations and layouts, including walls at 90° and 135° angles. With a profile depth of 50mm, it is among the strongest profiles in its category. The wide range of profiles, including reinforced mullions, allows for large-scale constructions.
All types of glass available on the market can be used as infills, including single, insulated, or bulletproof glass, made of clear, absorptive, patterned, or reflective glass. Additionally, infills can be aluminum panels, furniture panels, gypsum boards, or polycarbonate sheets. Maximum infill thickness is 45mm.
Partitions and doors of the PBI 50N and PBI 40E systems are covered by a single technical approval according to the European Union document ETAG 003, specifying intended use, scope, testing methods, and classifications.
