MPG Manufacturing LLC manufacturers MasterShield Gutter Protection, a patented, state-of-the-art gutter guard that features a proprietary, surgical-grade stainless steel microfilter housed in an aluminum body. Once installed, it captures all rainwater while keeping debris bigger than 50 microns from entering to cause a gutter clog. MGP is the originator and innovator of micro mesh gutter guard technology. It holds four U.S. utility patents with complementary patents in Canada and Australia. It is sold through a network of independently owned/operated dealers across the U.S. and Canada. MasterShield is the Gold Standard of Gutter Guards. Named to Qualified Remodeler's Top 100 Product list and GreenBuild's list of 10 hot products from the USGBC GreenBuild Show, we also have participated in ABC TV's Extreme Makeover: Home Edition. Our patented technology took top honors in a leading consumer magazines test of gutter guards. MasterShield was named best gutter guard by askthebuilder.com's Tim Carter. MGP recently added MasterShield Home Energy Barrier to its product line. Home Energy Barrier is a premium radiant insulation that complements the existing insulation in a home. It minimizes radiant heat loss or gain by reflecting up to 97% of radiant/emissive heat transfer, the predominant source of heat loss or gain in a home. Homeowners can expect to stay cooler in the summer and warmer in the winter, with lower heating and cooling costs throughout the year.
