Description atlas energyshield cgf formerly rboard is composed of a closed cell polyisocyanurate polyiso foam core faced with a non reflective coated glass mat facer on both sides.
Continuous insulation over concrete wall.
Your only option is to cover the inside of the exterior walls with a continuous layer of insulation as though you were insulating a basement wall.
If the user does not enter a continuous insulation sheathing r value or enters a value of 0 0 the software assumes a sheathing r value of 0 83.
Accessory manufacturer s instructions and recommendations for application over or behind products.
Products are not a nailing base for attachment of any kind.
There are several methods available to comply with the energy requirements of the iecc.
The u o factor for all frame walls is based on the r value of cavity insulation and the continuous insulation r value if used.
This refers to insulation uninterrupted by furring or by the webs of concrete masonry units.
It has several things going for it.
Wood steel masonry or concrete and eliminates the thermal bridging effects inherent in cavity insulation or interior insulation applications.
Below the effective r value for a wood wall assembly with r 12 fibreglass insula tion is r 10 8.
And placement of air water and vapour control layers need to be carefully considered.
The slab is insulated with 2 xps rigid insulation under slab and the rim joist is insulated with closed cell high density spray foam insulation.
And there is no effective way to fill the voids in an existing concrete block wall.
It s conceptually simple it works in every climate zone it handles moisture really well by keeping the wall framing warm and drying to the interior such that no interior vapor retarder is required it works with every type of wall construction e g.
When continuous foam insulation is specified 100 of the wall is assumed to be covered at the specified r value.
Foundation 4 xps insulation on the exterior of foundation wall this construction uses 2 layers of 2 xps rigid insulation on the exterior of the concrete foundation wall.
Faced with code compliance and the pressing need to design for green building goals and save on energy costs architects are turning to ci as an effective approach to eliminating segmented insulation with open gaps blocking thermal bridging and helping to improve thermal performance of the wall assembly.
Two inches of continuous rigid insulation not.
Products are not structural.
If a split insulation wall assembly is used the type of insulation.
The entire wall is assumed to have structural sheathing.
Although concrete masonry with integral insulation cannot comply under the table c402 2 requirement for continuous insulation because the webs of the masonry units interrupt the insulation the iecc provides an additional prescriptive option in table c402 1 2 based on the overall u factor of the wall assembly.
Continuous foam insulation to wood framing steel framing concrete and cmu substrates.
