I have worked with and used R&D Services for testing and consulting and product development for many years. The staff is very professional and easy to work with. The principals of the company have a broad understanding of the insulation industry as a whole and Reflective insulation in particular for our needs.
I have used R&D Services to oversee testing that we do at other labs so that they can certify the testing for us.
I continue to use R&D Services almost exclusively for our testing needs and highly recommend them.
