Note also that it was a "swing-in" door.). (Witness that lady who died when her non-FEMA-rated door was compromised and killed her. They die because they either a) didn't have or couldn't get to the shelter in time or b) they were in a non-FEMA rated shelter. People don't die (I have no reference for this statement) by getting "trapped" during and after tornadoes. There is exactly one disadvantage to having the door swing out. The wall deflection on the other hand will be noticeable.There is exactly one advantage to having the door swing in. More than likely you will not even notice the extra 4-1/4” of missing floor space.
#FRAMING AROUND METAL SAFEROOM CRACK#
This movement can cause the finished side of the wall to crack or chip. Interior walls built inside the stud will move with the building. Metal building walls also tend to have a small amount of natural movement (Bend rather than break). This forces you to cut each stud to length rather than buying precut studs. This lip either has to be bent straight or each individual stud has to be notched for the lip. The wall girt has a lip that folds under. Visually the wall will not be as straight. Now compare that with someone who is trying to maximize their floor space. This makes for a very efficient building. The trapped radiant hot & cold air naturally vents through the high rib of the wall panel at the top. The interior wall insulation keeps that air from making it into the actual rooms. The 8” void acts as a dead air space that traps the hot & cold air within the wall. The 2” of extra insulation is pushed into the 8” void. In addition to the building insulation he used 5-1/2” batt insulation in the 2 x 4 stud wall. It actually sits outside of the wall girt & run straight up with no breaks, notches or cuts.īrian has also benefited from an increase in thermal efficiency. Note in the picture how he runs his stud walls independent from the building. Brian is a cabinet maker and he did all of his own interior framing. Let us use Brian Fritz’s metal building located in Brenham, Texas as a case study. Most people want to try to build their wood frame inside this 8” void to maximize their floor space. This wall girt normally takes up approximately 8” of space. A sheeted metal building wall will have what we call a wall girt located directly behind the wall sheet. This approach is not always the best one. Most customers are concerned with maximizing their floor space. The most common question that I am asked in regards to framing is related to the exterior wall’s stud location. These substitute materials tend to be more cost effective & easier to use for the interior wall construction. However with multiple interior walls substitute products like wood or steel studs are commonly used. In some cases a simple interior partition wall can be constructed from conventional metal building materials. When we use the term interior framing we are speaking of the structure that supports the interior walls within a metal building. This means that non load bearing walls can be added virtually anywhere. Metal buildings generally have a clear span & require no interior columns.
