While a metal building can be constructed using either of the techniques listed above the iecc recognizes that metal buildings have developed their own unique form of roof insulation too.
Metal building roof insulation liner system.
Multiple thicknesses or layers can be combined in a double layer system to achieve high r values.
Up to 6 r 19 can be used in a single layer appliction.
There is a limit to how much fiberglass can be pinched between the wall panel and framing structure.
That form involves an exposed liner system which the iecc defines in chapter 2 as follows.
In addition to superior insulation performance compared to traditional methods the simple saver system is a liner system that provides through fall.
The optiliner banded liner system is designed to maximize the thermal performance of owens corning ecotouch insulation for mbi plus with purefiber technology light density fiberglass insulation in metal building roof and wall applications.
High r value liner system metal building insulation standard blanket metal building insulation works great in many buildings but there are times when you need more.
The simple saver system has been manufactured and marketed through thermal design over the past 30 years and has become the 1 specified high r value insulation system for metal buildings.
Fiberglass insulation roll options when choosing metal building insulation there are several thicknesses or r value s to choose from ranging from 2 5 8 r 8 to 9 5 r 30.
