- NedZink NOIR: Prepatinated zinc with a black surface for unique project aesthetics.
Installation involves two main types of gutters: those supported by brackets and those in a wooden box. Key specifications include:
- Gutter Brackets: Must comply with NEN-EN 1462 standards, with specific attachment and slope requirements.
- Roof Gutters: Made of NedZink NTZ, must meet NEN-EN 612 standards, with specific material thickness and length.
The document outlines specifications for roof gutters made of NedZink NTZ®, which must comply with EN 612 standards. It details the dimensional requirements for gutters, including the bottom width, front height, and back height, as well as the slope and expansion considerations. The document also specifies the use of standard or non-standard prefab gutters based on box dimensions.
Pre-treatment involves cutting gutter parts to length, making mitres, and soldering end pieces and expansion sleeves. Installation in a wooden box requires clips attached at specific intervals and dimensions, ensuring the gutter can move during expansion and contraction. The installation direction is preferably from left to right and against the slope.
Rainwater pipes, made of NedZink NTZ®, must meet EN 612 standards. Specifications include dimensions, material thickness, and standard lengths. Brackets for downpipes must be attached at specific distances, allowing for expansion. Installation involves overlapping pipes and ensuring proper bracket placement.
The quality of zinc-titanium roof or facade coverings depends on the design and execution of the roof structure. Proper ventilation is crucial to prevent corrosion from condensation. The document outlines design aspects, including temperature and humidity considerations, and provides guidelines for ventilated and insulated constructions.
Ventilated constructions require a damp control course and a ventilation cavity. The document provides detailed instructions for constructing ventilated and unventilated roofs, emphasizing the importance of proper ventilation to prevent damage from condensation.
The standing seam system is used for rain-tight roof and facade coverings. It allows for quick and cost-effective installation using preformed metal bays. The document describes the application of single and double standing seams based on roof pitch and provides details on securing bays with fixed and sliding clips.
The material thickness for both systems is 0.80 mm. The allowable bay width is determined by wind load and the height of the roof or facade. For roofs, the advised bay width ranges from 330 mm to 530 mm, with a maximum bay length of 10 meters to accommodate thermal movement. For facades, horizontal installation recommends a bay width of 300 to 430 mm, while vertical installation suggests a width of 500 mm or less.
Installation involves securing the standing seam bays to the subconstruction using fixed and sliding clips. Fixed clips prevent slipping, while sliding clips allow for thermal expansion. The positioning of clips depends on the roof pitch, with specific guidelines provided for different angles. For facades, the assembly is similar, with adjustments for vertical or horizontal orientation.
Thermal expansion and contraction are critical considerations. Bays longer than 10 meters require a transverse joint to accommodate movement. The type of joint depends on the roof pitch.
The systems must be fully supported by unplaned, untreated wooden boards with specific thickness and spacing requirements. Fastening involves using galvanized nails or AISI 304 stainless steel, with a zinc-layer thickness of at least 20 microns.
Assembly begins with marking out the center of the roof or facade area. Bays are laid from left to right or vice versa, with specific instructions for eaves abutment and clip attachment. The seams are folded closed manually or with a machine.
Details are provided for ridge abutment, verge flashing, wall abutment, roof penetration, and hip construction. Each connection type has specific requirements to ensure water-tightness and structural integrity.
The roll cap system is suitable for roofs with a pitch of at least 3° and facades. It consists of zinc sheets with upstands and wood rolls, covered by zinc caps. The system requires full support by wooden boards and uses fixed and sliding clips for fastening.
This guide provides comprehensive instructions for the installation of standing seam and roll cap systems, emphasizing the importance of proper support, fastening, and accommodation for thermal movement to ensure durability and performance.
The document provides detailed instructions for assembling wood rolls and lozenge systems on roofs. Clips must be attached to wood rolls as per specified distances in Table 6.1, and wood rolls are fitted with galvanized steel screws. Eaves aprons are secured with nails or screws, and roof bays are hooked into these aprons. The document emphasizes the importance of correct alignment and thermal movement considerations.
The lozenge system is used for covering sloping and vertical surfaces, with a minimum roof pitch of 25° or 18° if soldered. Standard lozenge dimensions and material thicknesses are provided, with options for custom sizes. The system includes soldered and sliding clips for support.
Proper ventilation is crucial for insulated roofs, requiring an air cavity between insulation and roof boarding. The lozenge roof must be fully supported by timber, with specific guidelines for nail and screw materials.
This system offers watertight cladding for roofs and facades with pitches between 7° and 90°. It uses preformed clips and a less complex substructure, allowing for straightforward assembly. The system is adaptable to various joint types and roof constructions.
NedZink NOVA COMPOSITE panels are designed for facade cladding, offering durability and aesthetic appeal. The panels are available in standard dimensions and thicknesses, with a protective foil and anti-fingerprint coating. The document advises testing processing techniques to ensure requirements are met.
The document outlines the processing techniques and installation methods for NOVA Composite panels. Key methods include sawing, shearing, perforating, milling, folding, bending, and rolling. Each method has specific requirements, such as using hardened bits for sawing and ensuring a minimum of 0.2 mm of the LDPE core remains intact during milling. The document also emphasizes the importance of temperature control, particularly avoiding bending zinc under 7°C to prevent cracks.
Various attachment methods for NOVA Composite panels are discussed, including gluing, clamping, visible screws, and internal bracket systems. The choice of method depends on the design requirements.
The Reveal Panel system is designed for facade cladding and can be installed vertically or horizontally. It consists of profiled zinc sheets with variable widths and is connected using a tongue and groove system. The system is typically applied with a material thickness of 1.0 mm, and standard solutions are available for most connections.
The document provides guidance on the compatibility of zinc with other materials. It highlights potential issues with bitumen, copper, lead, and certain wood types, recommending precautions such as using patination oil on lead and avoiding direct contact with corrosive woods like Western Red Cedar.
Soldering involves connecting metal parts using a metal with a lower melting point. The document specifies the use of soldering bits with specific weights and temperatures, and the importance of using appropriate soldering fluxes that do not corrode zinc or produce harmful vapors.
Zinc cappings are used to cover roof edges and protect against harmful effects such as UV rays and mechanical damage. The document provides construction details for new buildings, including the use of zinc clips and the importance of proper slope and attachment to ensure longevity.
Specifications:
- Maximum trim height: 20 mm.
- Clips should be placed 1 metre apart, with a width of approximately 80 mm.
- Zinc capping should end 20 mm from the rim and be soldered up to 12 metres with a 15 mm overlap.
- Expansion sleeves are required every 12 metres.
- Roof covering must be glued over the entire width of the roof edge.
- Start installation from left to right, beginning with a mitred corner.
- For 1 metre lengths, slide the zinc capping over the first clip and secure each joint.
- For 3 metre lengths, attach the first clip and two additional clips at 1 and 2 metres.
- Solder joints except for expansion joints.

Material characteristics NedZink NOVA and NedZink NOIR are types of preweathered zinc titanium which is manufactured by means of a phosphating process. The basic material is natural NedZink zinc titanium. By phosphating the material we obtain a surface which is very close to the regular natural patina. All characteristics of zinc remain unchanged during this process. Every laminated metal, NedZink material included, will show tensions in a certain way. This is a consequence of the laminating process. By our modern techniques these tensions are reduced to a minimum. In some cases these tensions...
