Making the roof watertight: now easier and faster

SIGA is known for thinking ahead and developing helpful innovations. This time, these innovations are based on the very robust and high-quality Majcoat® 350 sub-roofing membrane, which has been tried and tested thousands of times.

New are pre-welded shaped parts for penetrations in the roof and the so-called 3D pre-assembly of the sheet. Both give you the competitive edge you need today. Read for yourself.

3D prefabrication from SIGA

SIGA's particularly hard-wearing roofing membrane is now also available in 3D prefabrication. This means that the membrane is delivered ready-welded and precisely adapted to the respective roof shape and welded together. This eliminates the need for laborious welding on the roof. The work, which can otherwise take hours, is replaced by just a few minutes of laying out the pre-welded sub-roofing membrane to fit. This saves your company a lot of time on the construction site, and as we all know, time is money.

The new SIGA mouldings

But let's get to the actual topic: the Majcoat® 350 mouldings from SIGA. Once the surface has been covered with Majcoat® 350, the tricky parts come next. Here, too, this often means laborious welding work on the roof to get skylights, vapour pipes or the chimney tight. A lot of work, for which apprentices are often used. In the end, the doubt remains is everything really tight? But here, too, SIGA has recognised the problem and created the ideal remedy with the Majcoat® 350 roof system.

Complete system for the watertight sub-roof

As of now, the collar for round penetrations is available in various diameters, the skylight apron in various sizes and the universal outside corner for square penetrations, such as a chimney.

Here are the exact applications and dimensions:

  • Sleeve Ø 80 - 125 mm for round penetrations
  • Sleeve Ø 360 mm for round penetrations
  • Skylight collar 550 mm for skylights
  • Skylight collar 780 mm for skylights
  • Skylight collar 1140 mm for skylights
  • Universal external corner for square penetrations, such as chimney

With this you create every penetration on the roof with our SIGA products easily, quickly and watertight.
