Product catalog summary

Overview
The document is a brochure from METRA S.p.A. detailing the NC 50 I system for casement windows and doors. It is designed for industrial buildings and communal spaces that are not climate-controlled, offering durability, resistance to atmospheric agents, and high acoustic insulation. The system is available in various aesthetic lines: Piana, Sagomata, and Raggiata.

Certified Performances

Water Tightness: Certified under EN 1027 - EN 12208, the system prevents water seepage even at wind pressures equivalent to 111.54 km/h (600Pa).
Air Permeability: Under EN 1026 - EN 12207, the system withstands wind pressures up to 125 km/h (750Pa) with positive results.
Resistance to Wind Load: Certified under EN 12211 - EN 12210, it withstands wind pressures up to 203.6 km/h (2000Pa) while maintaining structural integrity.

Technical Features

Base Dimensions: Ranges from 50 to 60 mm.
Air-Water Tightness: Features open joint NC 50 I - WS and double rabbet gasket NC 50 I - DL.
Glass Thickness: Supports glass thickness from 4 to 42 mm.

Advantages

Wide range of finishes.
Easy maintenance.
High-level design.
Various opening typologies.
Minimal space requirement.
Maximum acoustic insulation.

Opening Typologies
The system supports multiple opening types including horizontal and vertical pivot casements, top hung casements, tilt-and-slide, double and single side-hung casements, tilt and turn, and bottom-hung configurations.
