Dow 2 rigid insulation r value.

R value expressed in ft2 h f btu. Because rigid foam plastic insulation products are not all aged in accordance with the same standards it is useful to publish comparison r value data. Thermosetting resins from dow can be used as an alternative to traditional formaldehyde based resins for binding mineral fibers in the production of insulation blanket products that go into building insulation systems and specialty insulation. This product typically has an r value of 3 6 to 4 0 per inch of thickness.

It provides r values that range from 3 6 to 4 2 per inch. R value determined by astm c518. It is lightweight and easy to install. Since styrofoam brand extruded polystyrene foam insulations are visco elastic materials adequate design safety factors should be used to prevent long term creep and fatigue deformation.

Foam insulation it features 3 ply facers for durability and moisture resistance and is energy star qualified for savings. Thd sku 740551. R value determined by astm c518 using the aging process in astm c1289 90 days 140 f 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first. Choose this option for areas that need a good amount of strength and water resistance.

The r value for foamular xps insulation is provided from testing at two mean temperatures 40ºf and 75ºf and from two aging conditioning techniques 180 day realtime aged as mandated by. The glass fiber reinforcement contributes to improved fire performance and dimensional stability. This material offers the highest r values about r 6 to 6 5. Super tuff r r 13 2 in.

Some products have reinforced facing to make them sturdier. 1 aged r value at 1 of cured foam 75 f mean temperature. 2 in x 4 ft x 8 ft. 2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first.

Thermax sheathing is a non structural rigid board insulation consisting of a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum facers on both sides. Expanded polystyrene insulation is similar to the foam used for packing peanuts and it s typically used for insulated concrete forms also knows as icf s.
