PRODUCT OVERVIEW Riverclack® is a “secret fix” standing seam metal roofing system that has proven itself in the most challenging climatic conditions across the globe. The metal panels can be roll formed on-site to any length, removing the need for end laps on long slopes. The joint between two adjacent panels features FULLY WATERPROOF Thanks to its unique gasket-free drainage joint, the roof system is watertight even when completely submerged in water. Installation is quick and easy and there is no need for pre-assembly of the clips. PERFORATION / FREE LOCKING SYSTEM COST / EFFECTIVE The...

UNRIVALED WATER TIGHTNESS The high-tensile side lap prevents any easy water penetration into the joint and, even if this should happen, the drainage channel captures the water and runs it away into the gutter, eliminating the risk of leakage into the building. Riverclack® has been designed to be watertight even when completely submerged in water. The secret fix locking system prevents any penetrative fixing of the panels, but the features that really set the Riverclack® system apart from the competition are the high-tensile, anti-capillary conical joint side lap and the drainage channel...

CHOICE OF METAL Riverclack® is available in a wide range of metals. Besides the superior 5754 aluminum alloy (guaranteed to deliver unrivaled performance in terms of corrosion resistance, mechanical strength and cost effectiveness), Riverclack® is also available in copper, stainless steel and titanium zinc. METAL LINEAR EXPANSION COEFFICIENTS When an object is heated or cooled, its length changes in proportion to the original length and change in temperature. The key factor for a Riverclack® panel is linear thermal expansion, which is dependent on the linear expansion coefficient of the metal...

SYSTEM COMPONENTS METAL PANELS PANEL WIDTHS WIDTH (MM) SITE ROLL / FORMING MACHINE / CURVING DRAINAGE / CHANNEL MINIMUM / ROOF PITCH Custom widths are possible, with or without a drainage channel, allowing for maximum freedom of design. The patented design of Riverclack® 500 and Riverclack® 550 panels, including their unique drainage channel, guarantees that the system is waterproof, even when completely submerged in water, without any risk of leakage into the building. This means that the system can be used, after steelwork deflection at panel ends, with roof pitches as low as 0.5% if the...

The fastening of Riverclack panels to the underlying metal structure is carried out by means of special clips made from thermoplastic material. The clips are fixed to the underlying structure with two screws and the Riverclack® panels are simply pressed into the clips. A series of clips are available to ensure optimal performance under any circumstances. CLIP OPTIONS STANDARD CLIP ENHANCED SMOOTHNESS CLIP CLIP FOR SPECIAL APPLICATIONS Glass fiber reinforced technical polymer. Technical polymer – low friction – no “stick-slip” motions. Reduced friction coefficient polymer. Dimensions: 105 x 50...

NON-COATED MATERIAL FINISHES / THE FINISHING TOUCH RIVERCLACK COLOR COATINGS Depending on the metal you’re using, Riverclack® can offer a range of finishes to enhance the visual character of your building. STUCCO EMBOSSED ALUMINUM Embossing is a unique stucco pattern that, besides its aesthetic qualities, helps reduce glare – an important issue with airports or buildings near busy roads. TREND COLORS Riverclack® 550 / Grip 600 Minimum order: none Delivery time*: 2-3 week WHITE ALUMINUM / SILVER MET RAL 9006 Minimum order: 1800m2 Delivery time*: 5-7 weeks ANODIZED ALUMINUM Aluminum anodizing...

HIGH SRI COLORS: FOR A COOLER ROOF The SRI (Solar Reflectance Index) measures a material’s ability to reflect heat. In warmer climates especially, SRI coatings help cool the roof and reduce the UHI (Urban Heat Island) effect. As part of a total system design, a cool metal roof can be an economical method to obtain better energy efficiency (more reflective roofs can save up to 40% in cooling energy). High-rating SRI colors can also contribute to LEED® credits for your building. EXCEL COLORS COOL COLORS Minimum order: 1800m2 Delivery time*: 5-7 weeks Minimum order: 1800m2 Delivery time*: 5-7...

Though white or light colors remain the most reflective, we can achieve relatively high SRI values even in dark colors, by using special pigments. The following table shows the SRI values for the Riverclack® Color Coatings range, plus some additional high SRI color options. A standard polyester coating has an average thickness of about 20-25 microns. It provides a reasonable resistance to UV rays and a moderate durability if exposed to particularly aggressive atmospheric agents. Polyester coatings deliver good value for money and are recommended for regions with mild, dry climates. deposit...
