This week the Pole Barn Guru answers reader questions about what financing is available for a post frame building, a question about ventilation for a metal trusses pole barn, and a comparison of concrete costs for post frame vs red iron buildings.
DEAR POLE BARN GURU: I’m looking to build a 25′ x 50′ pole barn 16 ft with an open lean-to on each side. I’d like the lean-to’s to be 20′ wide and the same depth (50′).so the total width would be 65′ by 50′ deep. My question is about financing. I’m not sure how financing would work. Do you have a financing co. or if that something I would get on my side? Thanks SHANE in BRIDGETON
DEAR SHANE: Financing is actually quite simple. Here is link to apply: https://www.hansenpolebuildings.com/financing/
DEAR POLE BARN GURU: I am looking at building a 30×50 pole barn with metal trusses. There is no soffit. I will be adding central hvac unit. Will stud up the walls between posts and add faced fiberglass Batts. Ceiling will be kept vaulted with metal on underside. Question is what insulation should I go with in the ceiling and will I have issues with not having a soffit or any roof venting? CHRIS in COLUMBIA
DEAR CHRIS: If you are insulating directly above bottom of trusses, then you need to ventilate this dead attic space. You could use rectangular gable vents spaced along each sidewall and have a vented ridge.
I would recommend blowing in granulated Rockwool, as it has a high R-value to thickness and is unaffected by moisture. You are in Climate Zone 3, so you should have at least a R-49 in your ceiling.
DEAR POLE BARN GURU: I am looking into your building system and I wanted to compare the general concrete amount and cost. Would you say that a pole barn uses less concrete than a red iron/tube steel building? If so, how much generally speaking and what details can you provide. BRONSON
DEAR BRONSON: Thank you for your interest in a new Hansen Pole Building.
Tube steel buildings are generally not considered to be permanent structures, so generally use very little concrete (and usually cannot be permitted, as they are not permanent).
Red Iron (Pre-engineered Metal Buildings) usually require you to hire an independent foundation engineer. As PEMBs have a significant outward force at base of frame verticals, they most often have a significantly large pier at each column (and require precision placed anchor bolts). Actual dimensions will vary greatly due to dimensions of building, roof slope, soil conditions and if there is a concrete slab on grade or not. It is not uncommon for single piers to take a yard or more of concrete.
Obviously many aspects come into play in determination of post frame building column concrete. Other than miscellaneous door columns, it would not be unusual for a 40′ x 60′ post frame building (as an example) to need under three yards of concrete for all column footings. Post frame slabs on grade do not require thickened edges – so a nominal four inch slab 40′ x 60′ would take 30 yards of premix.
