Liberty Dialysis Leeward, Oahu – 2022<\/em><\/p>\n\n\n\n

This dialysis clinic needed a way to keep cool. Their original plan was to install larger expensive air conditioners and have a higher energy bill.  MRC\u2019s solution was to properly insulate the roof from the outside, due to some roadblocks preventing an interior attic insulation application.  The clinic is only closed 1 day a week, so that prevented an interior installation of any kind of insulation, even spray foam because of lingering organic compound odors negatively impacting the condition of immunocompromised sensitive patients.<\/p>\n\n\n\n

Existing Roof<\/strong><\/p>\n\n\n\n

The original roof was standing seam metal painted blue. It was a heat sink that telegraphed heat directly into the building and made the existing air conditioners run all day, and the air conditioners were inadequate to keep the interior cool.<\/p>\n\n\n\n

Prior to the roof being insulated and coated, the interior floor temperatures would average around 76-77 degrees and sometimes hit 80 degrees during peak hours. After the new roofing solution, the floor temperatures (with portable A\/C units OFF) read 69-70 degrees<\/strong>.<\/p>\n\n\n\n

Temperatures are approximately 6-7 degrees cooler for the entire building, without the necessity for or installation of any additional mechanical\/electrical equipment (tested by RIM Architects).  The new exterior reflective surface coating showed a surface temperature of up to 105\u00b0.  This is a thirty-five-degree temperature difference between top roof surface and interior floor surface.<\/p>\n\n\n\n

The solution allowed the client to save up to $120k per year on operations by removing temporary A\/C units. There were 8-12 units being used at any given time, with each unit costing up to $1,000 per month in electric\/utility fees.<\/p>\n\n\n\n

New Roof-Over Design<\/strong><\/p>\n\n\n\n

MRC Roofing created a design build solution.  MRC installed a roofing system with an R-Value of 20 which included 2.5\u201d rigid and primed insulation boards from Carlyle SynTec<\/a>.  The rigid boards were precut\/fluted at the shop to fit directly over the existing standing seam metal roof panels.<\/p>\n\n\n\n

The rigid insulation boards lay flush and were adhered to the roof with DuPont\u2122 Insta Stik<\/a>\u2122 Quik Set (single component urethane) and stainless steel fasteners, followed by 1\u201d of three-pound spray applied polyurethane foam by Henry and 38 mils of white acrylic coating manufactured by National Coatings<\/a>, a Henry Company<\/a>.<\/p>\n\n\n\n

Design Build<\/strong><\/p>\n\n\n\n

MRC Roofing\u2019s Michael (Red) Coleman<\/a> design build was approved by RIM Architects<\/a>. This roofing system is not only insulating, but also a seamless waterproof barrier designed by a seasoned contractor.  Contractors should always be consulted for design build solutions.  Field professionals know what will work for cost effective solutions.<\/p>\n\n\n
