What Is the Difference Between Halo Exterra and Zip Sheathing?
What is the difference between Halo Exterra and ZIP Sheathing? Halo Exterra are rigid foam board insulation panels that feature a graphite polystyrene (GPS) foam core that is laminated on both sides with a layer of perforated polypropylene film. Halo Exterra panels marry a water-resistive barrier (WRB) to continuous exterior insulation, eliminating thermal bridging as […]
How Do You Protect Foam Board Insulation From Termites and Ants?
HOW DO YOU PROTECT FOAM BOARD INSULATION FROM TERMITES AND ANTS? For above-grade applications, it is best to protect Halo Exterra foam board insulation from termites and ants by using bug screens. For Below grade applications, Halo Subterra foam board can be purchased from participating plants with a termite-resistant additive. Termite Area Map Exterra is the Halo foam […]
Will Two Layers of Exterra Still Be Permeable?
WILL 2 LAYERS OF EXTERRA STILL BE PERMEABLE? No. Two layers of Exterra will not meet the minimum requirement of being “permeable”, which is 60 ng/Pa-s-m2, or 1 perm. A single layer of Exterra maintains it’s breathability up to a maximum thickness of 2” (71 ng/Pa-s-m2 or 1.2 perms at 2”). Exterra panels are laminated […]
Is Foam Board Insulation Sustainable?
Is Foam Board Insulation Sustainable? Yes, all foam board insulations are sustainable to some degree because they all help to reduce the heating and cooling loads of homes and buildings. As most heating and cooling fuel sources are currently carbon-based, these energy savings, in turn, will reduce “Operating Carbon Emissions.” However, a wide range of […]
Can I Use Foam Board Insulation With Batt Insulation?
Can I Use Foam Board Insulation With Batt Insulation? Yes, foam board insulation is an excellent complement to batt insulation. Foam board insulation can add insulation and eliminate thermal bridging when used in wall and ceiling assemblies insulated with batts. It can potentially replace the vapor barrier and house wrap as well. Here are four […]
