![]() When the building is placed so the wall which receives the greatest amount of sunlight is an end. So, under what circumstances might “end lights” be appropriate? The challenges of using strapping is it must be sized appropriately for the shear loads being transferred to the end of the building, and a significant length of strap must be wrapped around the column at each end, with lots of nails into the column. How would reinforcement be accomplished? By adding appropriately sized steel strapping Xs to the corner bays of the endwall, such as Simpson Strong-Tie CS or CMST: Their failure could cause wind pressures within the building, which it was not designed for, resulting in total collapse. ![]() Eave lights are not designed to be able to transfer shear loads and if placed below the truss, there is a strong possibility they will buckle, crack or fracture. There are some cases where it would work out better to polycarbonate panels on one or both peaked endwalls.Ī caution – eave light panels should not be placed on endwalls below the bottom chord of the end truss, unless significant reinforcement is done to the endwall framing. (For more reading on polycarbonate eave lights: ) Most often (and most cost effective) is to install them at the tops of the eave sidewalls. Polycarbonate wall light panels are a very affordable way to get natural lighting into pole buildings which will not have finished interior walls. They can be successfully used at top of one or both eave sidewalls or on triangles supported by end trusses. In my opinion (as well as those of others) translucent panels should not be used in roof plane for a variety of reasons ( ). THOMAS in CHICAGOĭEAR THOMAS: Polycarbonate panels may be used to provide natural lighting inside of non-insulated post frame buildings. Should you feel adding a top plate or plates to be necessary, please reach out to your engineer for clarification and a possible addendum to your plans.ĭEAR POLE BARN GURU: Are some kind of translucent panels an option for pole barn roofing or siding? Similar to UPS Truck roof. DAVE in PEYTONĭEAR DAVE: You should erect your building exactly as shown on your engineer sealed plans, otherwise you have relieved your Engineer of Record of any responsibility for structural adequacy. Can the trusses sit directly on the top of the headers or should I put a typical double top plate on top of the headers (not shown on the plans). It is so much easier to install now, than to wish you had done so after your building is completed.ĭEAR POLE BARN GURU: My pole barn plans (architect designed & engineer stamped) show a double 2×12 header bolted into the notched top of the pole frame. MIKE in FREELANDĭEAR MIKE: Only reason to not have a Weather Resistant Barrier between your wall steel and framing would be if you were going to use closed cell spray foam insulation (in which case it should be applied directly to wall steel inside). Seems like everyone is squarely divided on yes/no. in the spring and winter before crops, and I am thinking that some type of material might help with drafts and dust. ![]() Should I add a Tyvek or a “Block-IT” type material under the metal on the walls? I don’t know if I will ever finish the inside (maybe?) but where we live we get a ton of dust from farm fields etc. Continuing to play catch-up with the Pole Barn Guru reader questions, Mike answers questions about adding Tyvek under wall steel, attaching trusses to header on sealed plans, and the use of polycarbonate panels for use on post frame building.ĭEAR POLE BARN GURU: About to start the build of a 36 x 50 pole barn.
