Magroll 95mm Industrial Insulated Roller Doors Use of Plasticol coated steel ensures long lifespan and very good anti-scratch & wear properties. With a one-piece lath the PU insulation is chemically bonded to the outer skin ensuring the most rigid of laths. The design of our lath ensures that the profile rolls into a much smaller roll than other two-piece laths, which is great news for applications where space is limited. We produce a bespoke extruded bottom slat with a rubber extruded profile to seal the door to the floor. We install roller door Nothern Ireland wide.
