plates 72 a 73 a an maintaining the compression the diagonals of the wall section 70 can then be measured to determine if the structural members 24 are perpendicular to the upper and lower wall plates 72 a 73 a lack of perpendicularity can then be corrected and a veneer can then be assembled to the front face and nailed through the continuous facing 35 of insulating material into the structural members 24 to lock the perpendicularity into position this preferred mode of assembly takes advantage of the natural resilience or elasticity of the polystyrene which the insulating bodies 22 are made of in this particular case to offer greater maneuverability to the wall sections 70 an extra structural member 71 can additionally be installed during assembly of the upper and lower wall plates 72 a 73 a on the side 76 of the wall section which does not have a structural member the the extra structural member 71 can be nailed into upper wall plate 72 a and the lower wall plate 73 a the secured structural member can then mimic the other structural members and help hold the body of the last wall panel 10 u2033 in place by maintaining it in a compressed state during.
