| The Low Profile Retrofit Metal over Metal
System allows for the efficient installation of an MR-24® Standing Seam Roof System over
an existing through-fastened rib type roof with an existing minimum roof slope of
1/4" /12" and major corrugation heights of 1-1/2" or less. The MR-24 roof panels used on this system are
permanently seamed together with a full 360° "Pittsburgh" double lock seam to
assure weather-tightness and long-term performance with minimum maintenance expense.
The retrofit MR-24 roof clips, installed in
predrilled holes, securely attach the roof panels to the existing supporting structurals
with stainless steel tabs rolled formed into the panel seam. Stainless steel tabs
are more than 50% stronger than other galvanized standing seam tabs. The clip design
will accommodate expansion and contraction forces in buildings up to 500 feet wide.
Panel support blocks rest on the flat of the
existing panel and provide a bearing surface to transfer loads through the flat of the
MR-24 roof panel to the existing structurals.
The Low Profile Retrofit Metal over Metal
System includes a complete line of accessories (seamed-in curbs, stainless steel gutter,
etc.) designed to fit perfectly with the MR-24 roof system.
The MR-24 roof system has a U.L. Class 90
wind uplift rating and U.S. Army Corps of Engineers Guide Specification 07416
certification. |
