Exterior continuous insulation such as Halo Exterra has become a minimum requirement in building codes across most of North America for residential buildings. At the initial stages of exterior insulation, the thickness applied ranges from ½ an inch (13mm) up to 2 inches (50mm) depending on the climatic zone. As building codes progress towards more […]
Foam board insulation is an essential component in any wall assembly — it boosts R-values, helps manage moisture build up in the wall cavity and eliminates thermal bridging. But how thick should your layer of rigid insulation be? The answer hinges on nine general factors that determine the required thickness of foam board insulation on […]
Yes, foam board insulation is flammable. However, Neopor’s graphite polystyrene (GPS), which is used in Halo products, is treated with a fire retardant which greatly reduces flame spread and helps the fire to self-extinguish once the source of fire is removed. Thus, Neopor, and all Halo products, are approved for the construction of homes and […]
Check out this excellent example of how structural drywall, hold-down devices, structural ties, and minimal use of OSB can help builders save money and construct energy-efficient homes.
Discover the two options for creating a weather resistive barrier using Halo Exterra panels. Read the full article for the details.
Construction can’t always wait for a warmer day. If you’re building in the middle of a North American winter, check out these 5 steps to protect Halo’s rigid insulation products from cold-related damage
To take advantage of Exterra’s breathability, you’ll need that poly vapor barrier on the warm side to block vapor and moisture from traveling inside the building. Learn more about this code requirement here.
Exterra provides an effective air control layer by default, so technically speaking, you don’t need any additional house wrap. So, regardless of the method you go with, you’ll have that integral air barrier in your wall.
Interra is a far better bet if you’re looking for overall quality, performance, and stable R-Values. Spray foam, on the other hand, works well if you want to save time on installation, but it can be more costly overall.
Halo Exterra is not structural – it does not contribute structural strength to a home or building. However, despite not being structural, Halo Exterra can replace OSB sheathing if structural bracing is provided at the corners and certain sections of the wall to provide the needed resistance to wind and seismic loads.
