Is fanfold insulation a moisture barrier?
Exterior fanfold insulation is the foam-type of insulation that is applied between your home’s exterior and the siding, and it offers some protection from moisture, in addition to creating a layer of thermal insulation.
What is the purpose of fanfold insulation?
Fanfold insulation is an extruded polystyrene foam insulation which is designed to be applied to the exterior walls of homes, between sheathing (or pre-existing sidings) and usually vinyl siding. Its purpose is to provide thermal protection and to form a second barrier between the elements and the framing.
Is Polyshield waterproof?
POLYSHIELD is a prefabricated ELASTOMERIC-PLASTOMERIC (Plastomer-Polymer Bitumen) waterproofing membrane offering excellent performance.
What is fanfold foam board?
FANFOLD foam residing board is a thin perforated, extruded polystyrene foam board faced on one side with a plastic film facer and combines proven XPS foam technology with a unique design to enhance the application of new or replacement siding.
What is the R value of fanfold insulation?
R-Tech Fanfold 1/2 inch thick Roof Underlayment/EPS Insulation with Foil, 1.25 Density Type VIII, White Faced one Side, Foil on the Other, UL Listed, R-Value R-Value 2.27 @25F.
What’s the R-value of fanfold insulation?
What is Polyshield?
Poly Shield® is a laminated foam insulation board that reduces energy costs by adding R-value to your roof or walls. Poly Shield® is made of premium expanded polystyrene (EPS) rigid insulation that meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.
What is the R value of Poly Shield?
Polyisocyanurate and Polyurethane Polyiso is typically used with a foil facing and it has an R value of 7.0 to 8.0 per inch of thickness. The reflective foil facing makes it an excellent insulation board when radiant heat is involved.
What is fanfold corrugated?
Made to order, corrugated fanfold is a continuous corrugated board, accordion folded into a bale.
Why choose fan-fold underlayment?
It also provides better thermal insulation, helping to keep your room temperature where you want it. The easy to use fan-fold underlayment covers 100 square feet per pack and lays flat when you install it unlike traditional rolled underlayment which will curl back when you unroll it, making installation more difficult.
What is fanfold made of?
R-Tech FF (Fanfold) is a high-performance sheathing consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers. R-Tech FF meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.
What is Foamular fanfold?
FOAMULAR Fanfold is generally intended for use as a backer board for residing applications and comes in 50-foot sections for a faster install. Virtually impervious to moisture.
What makes our underlayment so durable?
The underlayment is extra durable, thanks to flexible plastic facers on both sides. Plus it’s perforated to allow moisture vapor to escape. The cut-and-fold hinge design ensures it lays flat. A perforated reflective facer that can enhance thermal performance is also available.
