For more than 35 years rmax has been creating insulation solutions based on the latest building science.
Dow polyisocyanurate cavity wall insulation.
The ashrae prescriptive continuous insulation requirements for steel framed above grade walls recognize this phenomenon and in most climate zones call for a layer of continuous insulation ci to be added to the assembly to help stop the steel thermal shorts that can decrease the energy efficiency of the wall system.
Pour in place insulation spray insulation polyol blends compatible with polyester and polyether polyol formulations the surfactants simplify the mixing of polyols and blowing agents maintain the blowing agents in the emulsion or solution and provide excellent emulsion stability.
Wall and ceiling overview.
R means resistance to heat flow.
Specify polyiso for cavity wall applications.
Thermax sheathing is a nonstructural rigid board insulation with a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum faces.
Thermax sheathing can be installed exposed to the.
Johns manville r 6 common.
Ask your seller for the fact sheet on r value.
Rigid insulation comes in panels of various thickness which provide different r values.
The unparalleled performance of continuous insulation results from the reduction of thermal bridges created by wall framing members.
The glass fiber reinforcement provides improved fire performance and dimensional stability.
We offer dow thermax polyisocyanurate and dow styrofoam xps extruded polystyrene known as blue board.
Foil faced polyiso astm c 1289 03 type i class 1 is the product of choice for masonry cavity wall construction.
Foil faced polyiso products have higher long term r values compared to other rigid board products.
Easy to work with rigid insulation can be incorporated into construction or added later to increase r value.
Thermax sheathing specially designed to hold a class a fire rating.
Polyiso is the best insulation for cavity wall applications.
1 values are consistent with the criteria of astm c578 and the requirements of the ftc r value rule 16 cfr part 460.
Case study salesforce tower.
The higher the r value the greater the insulating power.
2 vertical compressive strength is measured at 10 percent deformation or at yield whichever occurs first.
Continuous insulation provides improved performance compared to typical cavity insulation by creating an uninterrupted thermal barrier across the wall.
With a minimum of 70 recycled content the installed thermafiber products contributed to valuable leed credits helping the building earn a leed platinum certification.
We re proud to say our products can be found in some of the tallest and safest buildings around the globe like salesforce tower.
