Heat Welded Vinyl Systems
In this installation (on a metal roof) insulation filler strips are laid between the ribs to match the rib height. Then 4x8 sheets of efficient urethane insulation board are attached with special screws and plates. The average
added insulation value would be approximately R-14.
Sheet vinyl is applied over the insulation board. The edge of each sheet is
attached with barbed plates and
"high-load" screws throught the
insulation into the top of the ribs. (Unlike most other contractors, we
anchor all screws and plates into the
"top" of the ribs where the metal is
strongest.)
The next sheet of vinyl is rolled out over
the plates and screws of the previous
sheet, and the seam is permanently
"hot-air welded" with a robot welder.
Speed and temperature of the efficient
welder are set for the climatic and job
conditions for a permenant weld that
can not be pulled apart.
Penetration stacks are secured with a
pre-made factory boot that is friction fit
over the pipe and heat welded to the
field membrane.
The finished roof system gives the
owner a durable, long lasting roof.
Because snow and ice do not
adhere to the vinyl there is never a
build-up at the roof edge.
The added insulation will also allow for an eventual payback of the
new roof.
