EPAMS 100% metal outlets

Technical Approval 14+5/01-656 CSTB - for Roof Outlets and 14+5/01-656 *01 Addendum.

The EPAMS® system is a combination of SMU /ESIGN cast iron pipes, fittings and accessories, jointed with SMU Rapid 2® stainless steel couplings.

The EPAMS® outlets are made of 3 different parts:

  • The Anti-Vortex mechanism, aluminium grating. Bolted on the bowl is the same for all the outlets.
  • An identical stainless steel bowl for all the outlets, on which different components can be assembled depending on the field of use.
  • A stainless steel tail available in four DN: 50 – 75 – 100 – 125.

Installation

The EPAMS® outlets are easy to install.
The installation has to be done in accordance to the good practice and the Technical Approval requirements.
SAINT GOBAIN PAM EPAMS all metal outlets full guarantee mechanical strength and durability.
They totally comply with EN 1253 on every specific point: flow capacity, watertightness, solidity, mechanical strength, heat resistance and climatic stresses (resistance to Ultra Violet…)

The grating and the anti-vortex mechanism are made in one piece. This allows quick removal with no risk of mistake at reassembling, easy intervention and maintenance.

EPAMS outlet to be welded

Application field:

This roof outlet is especially designed to be welded (or brazed) in gutters or in metal roof valleys

EPAMS outlet with flange

Application field:

This roof outlet can be used for roofs containing extra-thick metal gutters or valleys as well as for roofs waterproofed by synthetic or bituminous membranes

EPAMS outlet with steel plate

Technical:

The plate is fixed to the roof outlet body in the factory by bonding then tightening with 6 nuts on the 6 bolts. This assembly can never be disassembled. The stainless steel plate is tinned on the two faces.
Plate size 500 x 500mm with a thickness of 0.4 mm.

Application field:

This roof outlet is used on all the roofs mentioned in the field of application of the French Technical Approval14+5/01-656, except for those with waterproofing by synthetic membrane.

EPAMS outlet for flexible PVC membrane

Technical:

The plate is fixed to the roof inlet body in the factory by bonding then tightening with 6 nuts on the 6 bolts. This assembly can never be disassembled. The dimensions of the steel-PVC laminated plate are 500 x 500mm with a total thickness of 1.8mm. It consists of a galvanised steel sheet, thickness 0.62mm, covered in the factory on one face by a layer of epoxy (from SARNAFIL). The steel part contains 4-drilled holes for possible fixing to the roof. This plate is compatible with the PVC SARNAFIL membranes, Series G 410, of the “G 410” processes, to be applied as described by SARNAFIL.

Application field:

This roof outlet is used on non-accessible roofs and/or with equipment zones, and waterproofed by synthetic membranes according to the SARNAFIL Technical Assessment. Waterproofing is provided by a weld between the various PVC elements to seal it in a traditional way. The membrane may be visible or may be given heavy mineral protection. For this latter case, it is possible to use fine gravel but in this case the roof outlet is to be fitted with an elevating kit for the anti vortex mechanism.
