This week readers “Ask the Guru” about best the practices for insulating an old 1993 pole barn, if a fireplace can be added to a “bardo,” and whether or not Hansen Pole Building supplies wood wall sheathing for exteriors.
DEAR POLE BARN GURU: Hello, I have a 28′ x 36′ x 13′ high pole barn in Western NY that was built in 1993. The ceiling is very well insulated with fiberglass. The walls are drywalled, however, there is no wall insulation behind the existing drywall. Rather than removing the drywall, I wanted to dense pack cellulose insulation into the walls. Without a paper facing vapor barrier, I would elect to simply use a vapor retarder paint on the walls. The dense pack insulation would be right up to the exterior metal siding and would achieve approximately R-30 in the walls. Does this sound like a viable solution or is it not a good idea? My only concern is trapping moisture. Thanks TONY in BROCKPORT

DEAR TONY: Dense pack cellulose is infused with fire retardant chemicals. If moisture is induced, these chemicals react with steel to cause premature degradation. As such, I would not recommend using it for your application. Rather, granulated Rockwool would be a much better design solution. With a vapor retarder paint on walls, this assembly should dry to exterior. In the event any moisture would form in wall cavity, Rockwool would not be negatively affected by it.
DEAR POLE BARN GURU: Can fireplaces be added to your barndos? DARLENE in FROST
DEAR DARLENE: Under 25% of new homes have fireplaces. This decline of fireplaces in new homes is primarily due to practicality and changing preferences.
Cost and Energy Standards
· Rising construction costs and stricter energy efficiency standards have made fireplaces less appealing for builders and buyers alike.
Safety and Maintenance Concerns
· Modern homeowners often prioritize safety and ease of maintenance, leading to a preference for alternative heating methods.
Lifestyle Changes
· As lifestyles evolve, many people are opting for open floor plans and modern designs not accommodating traditional fireplaces.
Technological Advancements
· Rise of efficient heating systems and electric alternatives has further diminished need for traditional fireplaces.
With this said, yes, our post frame barndominiums can be designed to allow for fireplaces of any type able to be incorporated in other structural building systems.
DEAR POLE BARN GURU: Do you do buildings with wood exterior? ROB in BAYFIELD

DEAR ROB: We often provide buildings with T1-11 with grooves every 8″ or rough sawn finish with 1×4 cedar battens. Having built one for myself, using 1×8 STK Cedar channel siding, I would never use wood siding again, as it requires far too much upkeep. Seemingly it was a perpetual need to solid body stain, especially on south facing wall. Steel siding will be your most durable and cost effective. Steel siding is also available in a board and batten look, even with a wood grain finish!
DEAR DYLAN: Your easiest design solution is to place rigid insulation boards down 2′, then out horizontally (most Building Departments accept 2′ out). This places all of your insulation above tops of concrete collars. This guide should prove helpful (keep in mind, it is for traditional stick built, but concrete has no magical frost preventive properties, so replace “concrete” with compactable fill): 
DEAR DAVID: It is going to be far easier (and less expensive) to properly grade your site and compact fill before your building begins, than trying to do it afterwards. Working equipment around posts and walls is going to be time consuming and can result in structural damage, if not done carefully.
DEAR BRIAN: While pre-painted ribbed steel siding is the most durable and cost effective siding available, some jurisdictions just do not ‘get it’ and demand (as is their right) alternative sidings. When we engineer using commercial bookshelf wall girts, we limit deflection to what sheetrock will withstand, so they are effective with any type of external siding materials. No changes to structural system will need to be made, other than vertical blocking between wall girts every 4′ (in order to provide a nailing surface for edges of OSB). If you use vinyl siding, then 7/16″ OSB and a Weather Resistant barrier will be necessary. Typical nailing will be 8d common nails at 3″ on center along panel edges.
DEAR POLE BARN GURU: Can a pole barn building have a basement? CLARK in HILLSBORO
DEAR POLE BARN GURU: I’m building a 36x64x16 8′ truss spacing . We want exposed truss and ceiling cavity without the use of drop ceiling or blown in bat. My question is it smart to use 2×6 purlins instead of 2×4 to allow for room for faced 6″ insulation to get a R19 value, besides spray foam what are some other options. Thanks. ZACH in LAUREL
DEAR POLE BARN GURU: I have read about the benefits of hanging sheetrock on horizontal members (exterior wall with bookshelf girts) that you wrote (
DEAR POLE BARN GURU: Hello, my building is recently completed and I am interested in adding concrete stairs in front of the four foot man-doors. Should I cut out the splash plank, drill and insert rebar in the slab to anchor, pour under the now exposed 1 1/2″ reveal under the door threshold? Or, Frame in the steps and pour concrete against the splash board? KEVIN in SILVERDALE
DEAR POLE BAR NGURU: How would the bracing effect of full height 5/4 x10 wood siding (board & batten) attached directly to the girts compare to the bracing provided by metal siding on a pole barn? Thanks. KEVIN in WEST CALN
DEAR POLE BARN GURU:
DEAR BEN: Thank you very much for your kind words. Due to liability issues we are unable to offer this sort of service. You might try reaching out to one of our independent third-party engineers John Raby (john@raby-assoc.com) to determine if he would have an interest in assisting you.
DEAR POLE BARN GURU: When installing horizontal sheeting, does the top sheet always cover the bottom sheet when joined? GARY in EUFAULA
DEAR POLE BARN GURU: 
DEAR POLE BARN GURU:
DEAR SEAN: A beauty of post frame (pole) building construction is virtually any variety of materials can be utilized for roofing and siding. This would include have a bricked exterior as well as a shingled roof.
DEAR JUDYANN: Thank you very much for your interest in a new Hansen Pole Building. Because all of our buildings are 100% custom, we can design and provide virtually anything you can imagine as a post frame building. This also means we have no catalog. Find a home design you like and we can fit it into being a post frame building. One of our Building Designers will be reaching out to you to further discuss your needs or you can dial 1(866)200-9657.
DEAR ALYSSA: In an ideal world you would have just asked your Planning Department why. In researching your question, I believe your Planning Department is correct – even though YOU are not serving food or alcohol, guests may bring their own. This makes it an “eating establishment”.
I realize this sounds simplistic, but it is what needs to be done. Building Codes require sites to slope away from buildings by at least 5%. This would be six inches of drop in 10 feet. If you do not have this type of slope away from pressure preservative treated splash plank at building base, you need to start digging.
DEAR DAVID: A beauty of post-frame (pole) building design and construction is you can side and roof them with any materials you can imagine! Not only will it be every bit as good, it will also be more affordable.
DEAR POLE BARN GURU: Can Hansen build the barn on top of an existing slab? CLYDE in BELLVILLE
DEAR POLE BARN GURU: My trusses are 8 feet on center will the metal ceiling liner span that 8 feet without sagging if I blow in fiberglass insulation? RODNEY in LAKE ELMO
DEAR TED: Sadly I just cannot see a scenario where moving this building becomes truly practical. If you have lots of free time, you could completely disassemble it and rebuild in a preferable location. However, you are reusing materials and things never seem to fit back together as tight as they did originally. If you are not going to rebuild, you might consider offering it to someone who will take it down and haul it away – it would save you time and effort and someone else can have headaches of teardown and rebuild.
DEAR GREG: Your steel liner has created a surface trapping any and all moisture inside of your building. In my humble opinion you have just one more example of why steel liner panels are not a good design solution for most buildings.
DEAR ROB: Even with Code mandated six inch minimum hold up above grade for vinyl siding, it experiences a significant amount of damage just as you describe. Our house has steel wainscot and it has performed admirably other than where our daughter-in-law drove a riding lawn mower into it. All it took to repair was removal and replacement of a few short steel panels.
