Roof edges Roval-Solo

Patentno. 1010352

The Roval-Solotrim is a patented, single-roof trim fitted with a specially-developed EPDM sealing tape. The roof trim is fitted directly on to the finished roof covering using stainless steel screws and stainless steel neoprene sealing rings. Suitable for both bituminous and synthetic roof covering. The roof trim is clamped on to the finished roof.
The Solo-trim has pre-drilles holes ( 6 mm) in the tailpiece of the trim, 50 mm from the ends and spaced at distences of 300 mm . the cover click-coupling is made in a special UV-resistant quality and seals the expansion joints between the individual roof trims. The joint at the front of the Solotrim is linked with an aluminium connecting plate with a thickness of 2 mm. This plate has a width of 40 mm. The Solotrim slides intop a recess with a beveled edge in this plate. The purpose of the bevelled edge is to provide a mounting stop. Its dimensions aloow the absorption of any expansion due to changes in temperature (1 mm/m1).


  1. The roof edge trim must be anchored to the sub-construction and must be suitable for the application of a bituminous or synthetic finishing. The roof trim must be windproof.
  2. The top of the roof edge trim must be finished with a wall plate. The thickness of this wall plat must be at least 18 mm.
  3. The topsurface of the roof trim must drain towards the plane face of the roof.
  4. When the bituminous or plastic edgingstrips are placed, it must be ensured that no level differences arise at het overlapping sections.
  5. Carry out internal and external angles with welded corner pieces.
  6. Harmonize the height of the Solo(kraal)trim with the thichness of the wall plate. The faade joint must be covered over a distance of at least 15 mm.
  1. The architectural roos trim must be completely carried out an finished before the roof covering is applied. The roof trim must be windproof.
  2. Stone or metal roof trim must be pre-coated with a bituminous solution if a finshing with bituminous edging strips is applied.
  3. The connection of the bituminous and plastic edging strips must be carried out level and windproof. The width of the bituminous edging strips is 1.1. metres maximum.
  4. The overlaps of the edging strips must be allow for the Solo(kraal) trim to be connected level. As a result, the connection between the Solo(kraal) trim and the roof edge finishing will be waterproof.
  5. The work can be carried out with a an open flame if the trim is fireproof.
  1. In principle, start with a welded 500 x 500 mm corner piece (A), followed by the full lengths. The profiles are fitted with pre-drilled screw holes and EPDM sealing tape.

  2. Adjacent profiles are connected via an aluminium at the front. This plate has a width of 40 mm; the Solo slides into a recess with a beveled edge in het plate. (B) The aluminium connection plate has an integrated spacer, which automatically ensures the required expansion joint distance of 4 mm . (C) during the assembly.

  3. Align the Solotrim and screw into a wooden wall plate with stainless steel/neoprene sealing rings (D).
  4. Cover the top of the expansion joint with a synthetic coverclick-coupling (E).
