Premium Insulation Offers Ideal Heating and Cooling Efficiency
Constant research, testing and development have led to a Sprung structure that provides naturally better climate control.
Unlike a metal building that compresses insulation at many locations within the finished product and lowers the R-value (the measure of thermal resistance), a Sprung structure keeps the insulation much closer to its maximum thickness for maximum performance and comfort. It also reduces your climate-control costs and absorbs sound for better acoustics.
The structure is ideally suited to almost any climate imaginable, from -50˚C to +50˚C.
When you build a Sprung structure with insulation, you also get our high-strength, rip-stop interior membrane. This membrane is more durable than drywall and offers exceptional fire-retardant capability.
Five reasons insulation performs better in a Sprung building
- Our highly tensioned exterior architectural membrane provides a significantly better airtight building envelope.
- There is no differentiation between wall and roof of a Sprung structure, which provides a more consistent R-value rating throughout the entire building envelope.
- Up to 9-inch-thick (R-30) layer of Johns Manville formaldehyde-free fiberglass blanket insulation means better performing insulation.
- A double vapor barrier system helps reduce mold and mildew.
- A reflective foil backing doubles both as a vapor barrier and to retain and reflect radiant heat, adding to the overall energy efficiency.
Why We Use the Johns Manville Formaldehyde-Free Fiberglass Blanket
- It is the only formaldehyde-free fiberglass product of its kind in the world.
- The aluminum foil backing increases overall efficiency, retaining or reflecting radiant energy.
- The blanket is eight or nine inches thick, exceeding building code requirements.
- The R-25 or R-30 rating of the fiberglass blanket contributes to an extremely energy-efficient system.
- The fiberglass is certified by Scientific Certification Systems (SCS) to have a minimum recycled content of 25%, comprised of 20% post-cosumer bottle glass and 5% post-industrial glass.
