What is the R value of polyisocyanurate?
For the R-value of polyiso wall insulation, a full thickness, 180 day aged value is recommended. Foilfaced polyiso has an R-value of about 6.5 per inch and permeability faced polyiso wall insulation has an R-value of around 6.0 per inch.
What is Enerfoil used for?
Enerfoil is designed to be a non-structural, non-permeable sheathing in cavity wall, stud wall or interior basement construction. When used with IKO AquaBarrierTM Tapes, IKO Enerfoil can act as insulation, air barrier and weather resistant barrier all in one!
What is the R value of 1 inch insulation board?
This product typically has an R value of 3.6 to 4.0 per inch of thickness.
What is Enerfoil?
Enerfoil is a rigid polyisocyanurate insulation sheathing with a foil facer laminated on the top and bottom side. It is designed to be non-structural sheathing for cavity wall, stud walls or in cathedral ceiling construction. IKO Enerfoil Insulation Sheathing is dimensionally stable and can be sized with ease.
Is polyisocyanurate insulation waterproof?
Polyiso. Polyiso is a rigid foam board insulation used for roofing and for insulating walls and ceilings. This creates its closed-cell structure and makes polyiso exceptionally waterproof.
Does polyisocyanurate insulation absorb water?
The material standard for polyisocyanurate is ASTM C1289. Glass faced polyiso goes from absorbing 14x more water than XPS to absorbing 30x more water than XPS when measured using the same method. Foil faced polyiso goes from absorbing 1.5x more water than XPS to absorbing over 7x more water than XPS.
What is foil polyisocyanurate?
Johns Manville AP™ Foil-Faced Foam Sheathing board is rigid polyisocynurate foam sheathing that provides exceptional heat, moisture and air control to protect your building’s exterior walls, and when installed correctly, eliminates all major thermal bridges that cause heat loss.
Do you have to tape insulation seams?
Jan 19, 2008 · If you are installing insulation and have to piece it together and it has paper on one side, you tape the seams to get a better seal. You can use packing tape but over time it will degrade. If the fiberglass insulation has no paper at all, it is unfaced and has no vapor barrier and does not need taping.
What is the difference between polystyrene and polyisocyanurate?
Polyiso has a higher range of R-value per inch of thickness when compared to extruded polystyrene products. At this thickness, the advantage in thermal performance of polyiso over polystyrene is at least 20%.” Polyiso insulation boards are pressed between facing material.
What is the thinnest insulation board?
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
Is Polyiso breathable?
A coated glass fiber facer is laminated onto the board top and bottom, making it breathable.
What happens if polyiso gets wet?
If an insulation, polyiso or polystyrene, is submerged in water, the insulation benefit disappears as the water short circuits around the insulation. Insulations must be kept dry. If minor contact does occur, the foil facings and closed cells of polyiso provide excellent water resistance.
What kind of insulation is Iko sheathing wall insulation?
IKO Enerfoil Sheathing Wall Insulation is a rigid, polyisocyanurate foam insulation board with high thermal properties. It is constructed from closed cell polyisocyanurate foam core bonded on each side to aluminum foil facers during the manufacturing process.
What kind of material is Iko enerfoil made out of?
It is constructed from closed cell polyisocyanurate foam core bonded on each side to aluminum foil facers during the manufacturing process. Enerfoil is designed to be a non-structural, non-permeable sheathing in cavity wall, stud wall or interior basement construction.
What can Iko aquabarrier TM sheathing do for You?
When used with IKO AquaBarrier TM Tapes, IKO Enerfoil can act as insulation, air barrier and weather resistant barrier all in one! Enerfoil is lightweight, easy to handle and can be sized with ease and has a high thermal R-value (R6.2 per inch) that provides outstanding insulation protection, which helps reduce energy costs.
What kind of material is ikotherm polyiso made of?
IKOTherm Polyiso is composed of a select kraft paper reinforced with fiberglass strands for high strength and excellent absorption for both hot mopping and adhesive attachment methods. The product also performs well with mechanical fasteners.
