Polyguard was founded in 1953 in Oklahoma by Robert Nee and Frank McNulty. Polyguard moved to Ennis, Texas in 1978. John (current CEO) and Kathy Muncaster purchased Polyguard in 1986. In 1987, John and Kathy decided to allow the employees to directly benefit from their hard work by offering all of the employees an opportunity to be part of an Employee Stock Ownership Plan (ESOP). In December 2014, the company became 100% ESOP owned.
Polyguard's unique employee ownership program allows its employee-owners an opportunity to participate in a no-cost retirement plan that's based on the success of the company as a whole.
What does Polyguard do?
Polyguard Products specializes in products that protect surfaces and structures from moisture, water and other undesired substances. Polyguard is currently operating under three "core" divisions with a number of growing divisions under the Polyguard umbrella.
Polyguard’s Architectural Division offers the Integrated Building Envelope™ System, with air barriers, masonry through wall and window flashings, below grade structural waterproofing systems, and composite drainage panels, all connected using engineered transition detailing assemblies which assure envelope integrity.
Polyguard’s Pipeline Division was the first coating manufacturer to highlight the cathodic shielding problem and the first to develop a coating to address the shielding problem. We have introduced a 2-part epoxy coating with 30% – 50% longer pot life than the competition.
Our Mechanical Division offers weather and vapor barrier systems to keep pipe and duct insulation dry, as well as a unique RG-2400® coating to stop corrosion under insulation (CUI).
Polyguard's Specialty Products Division is comprised of products for Highway, Residential, Flooring and Private Label applications.
A new innovation from Polyguard is the TERM Barrier Systems. Backed by 18 years of university research and ICC Evaluation Report #3632, you can optimize building waterproofing by adding non-chemical termite and insect barriers.
In May of 2016, Polyguard introduced a new business unit called Poly Wall Building Solutions - Moisture and Air Stop with Us.
Polyguard's Residential Division manufactures a market-leading line of waterproofing and air barrier membranes designed to enhance the integrity of your structure. Our products are all made in the USA and have been tested to withstand the most rigorous requirements in the construction industry. With 60-plus years of manufacturing excellence and a culture only found in an employee-owned company.
Think of Polyguard as an innovator and manufacturer of barriers – not just barriers against moisture and corrosion, but against contaminants like radioactive radon gas and methane. No sick buildings here.
