Absolute­ly. The exte­ri­or walls are two lay­ers of con­tin­u­ous insu­la­tion, the den­si­ty of sol­id con­crete and a lay­er of ½” gyp­sum board on the inside all con­tribute to supe­ri­or sound sup­pres­sion of STC 50 for the whole build­ing enve­lope. Note: A wood frame sys­tem of equiv­a­lent STC rat­ing would be 2 x 4 studs spaced 16˝ o/​c, with 3½˝ absorp­tive mate­r­i­al, 1 lay­er of 5 /8˝ Type X gyp­sum board on resilient chan­nels spaced 16˝ o/​c, and 2 lay­ers of 5 /8˝ Type X gyp­sum board on the oth­er side.

Exte­ri­or wind dam­age is respon­si­ble for 25% of all home­own­er insur­ance claims. That doesn’t include the inte­ri­or loss­es that occur when dam­aged win­dows and roofs let rain wreak hav­oc inside. While we can’t pre­vent wind­storms, we can lessen their dam­age by plan­ning home designs with wind-resis­tance as a top pri­or­i­ty.

While many build­ings these days are designed with the same basic prin­ci­ples, there are times when excep­tions need to be made.

Yes, if the fol­low­ing cri­te­ria is avail­able for the design of a con­crete lin­tel (beam) over the open­ing – con­crete lin­tel depth min­i­mum 16″ (400 mm) or more with no point loads. Larg­er open­ings would require an engi­neered design.
