The perfect wall the perfect wall is an environmental separator it keeps the outside out and the inside in.
Rigid insulation exterior wall detail.
In its guide to insulating sheathing bsc describes the use of exterior rigid insulation board in the enclosure assembly to act not only as insulation but also as the primary sheathing and in certain areas as the drainage plane and vapor control layer for the wall assembly see exterior sheathing profiles diagram.

Thermalwall ph rigid eps insulation board for insulating the exterior walls of homes the advantages are plenty here panels are between 4 5 inches and 8 inches thick the exterior insulation is continuous and they can be attached with 6 inch 10 screws from 4 to 6 inches long.
Concrete block with interior rigid insulation and stucco applicability all hygro thermal regions bsi 001.
Thermal bridging affects whole wall r value.
It s also virtually impervious to moisture preventing loss of r value due to moisture penetration.
Tape the seams in the osb with flashing tape to establish the primary air barrier.
The top leg is taped to the wall sheathing with contractor tape.
Add house wrap according to manufacturer s specifications and then install the first layer of foam to the walls.
The wall assembly can control rain air vapor and heat.
By creating continuous insulation the air and water barrier can also be installed in the exterior wall cavity with minimal interruption.
This places the thermal mass inside the insulation layer.
Industry trend to using exterior rigid insulation increased thermal value condensation resistance increased air tightness possibly increased rainwater management possibly need to develop a means to attach cladding over thick layers of exterior insulation that can meet the following requirements.
Exterior insulated masonry walls are walls that have insulation on the exterior side of the thermal mass.
In these walls continuous exterior insulation envelopes the masonry minimizing the effect of thermal bridges.
