Tag Archives: post protectors


My now 23 year old daughter Allison sent me this meme once. I found it quite appropriate for self use when I mentioned a product in yesterday’s article which I had never written about.

From Homework Design, the makers of Plasti-Sleeve® Post Protectors is another innovation towards post frame building longevity – the Plasti-Skirt.

Plasti-Skirt enhances quality and protection for post frame buildings. Rot and decay of skirt boards (aka Splash Planks) can compromise your building structure with serious problems. Many new wood preservatives are evolving in the wake of CCA treatment being phased out for many uses. However most of the new treatment formulas are unproven long term… but plastic is. The HDPE plastic used in Homework Design products is completely resistant to moisture, organic matter, concrete, most chemicals (including wood preservatives), animal wastes, etc. Use Plasti-Skirt and Plasti-Sleeve for total protection and confidence on your new post frame buildings.

Plasti-Skirt is a heavy duty u-shaped plastic cover for skirt boards in post frame construction. With an inside measurement of 1-9/16 inches and 7-1/4 inches tall, it fits ideally over 2×8 skirt boards. Standard lengths are 8’3” and 10’3” to provide adequate overlaps between adjoining members.

While most new generation pressure treating chemical formulations are no longer (or minimally) corrosive to steel trims and siding, Plasti-Skirt does provide a positive barrier between treated lumber and steel trims and siding.

Skirt boards are largely overlooked as being a key structural component of post frame buildings, however they are essential to the proper transfer of wind shear loads to the wall columns and thence into the ground. Plasti-Skirts protect the vital skirt board from ground contact, decay, concrete, moisture, etc.

Quick to install, Plasti-Skirt cuts easily with snips, saw, or knife.

Concerned about premature skirt board decay? Or maybe it is termites you fear? If so Plasti-Skirts might just be the answer you were in search of!

Pressure Treated Lumber

Preserving Wood Columns Beyond Code Requirements

The Building Codes (IBC – International Building Code and IRC – International Residential Code) specify minimum requirements for pressure treated lumber used to structurally support buildings.

My previous dissertations on pressure treating are available for your reading pleasure here: https://www.hansenpolebuildings.com/blog/2012/10/pressure-treated-posts-2/ and https://www.hansenpolebuildings.com/blog/2014/05/building-code-3/

Pressure Treated PostsHansen Pole Buildings Designer Kelly brought to me the question (posed by one of his clients) about the available (and feasibility) of the utilization of greater levels of preservative treatment chemicals for wooden columns embedded in the ground.

Higher levels of pressure preservative treating are available for pressure treated lumber. However they are going to be done by special order at the pressure treating plant. Special orders come with “special” (read – higher, sometimes MUCH higher) pricing, as well as extended periods for delivery of product.

The reality is, if the Code requirements will last the useable lifespan of the building or more, an increase in the treating levels is probably not the best investment of a building owner’s hard earned funds.

If one is skeptical (or even unbelieving) about the ability of properly treated pressure preservative columns to last when embedded in the ground, there are some alternatives.

Plasti-sleeves® https://www.hansenpolebuildings.com/blog/2012/04/plasti-sleeves/ or Post Protectors™ can be placed over the in-ground portion of pressure preservative treated columns to isolate the wood from contact with the surrounding soils.

Carrying the argument even further, columns can be removed from ground contact completely! Engineered brackets are available which allow columns to be mounted to foundations, or even concrete piers which are poured into the ground: https://www.hansenpolebuildings.com/blog/2012/09/concrete-brackets-2/.

Also available, are patented pre-cast concrete short columns with brackets on top, which can be placed into previously augured holes and the wood columns are then attached to the brackets.

The end game is, there is a design solution available to fit every future building owner’s level of comfort and pocket book when it comes to pressure treated lumber.


Hansen Buildings is always looking for new products or techniques which could be incorporated into our pole buildings to offer clients a better product. One resource we utilize is to monitor websites of others who provide post frame buildings, whether constructed or DIY (Do-It-Yourself) building kits.

In checking out one of these sites, I found this offering:

post shieldPostShield protects your barn’s posts against rotting with a layer of modified asphalt. A durable film layer protects the asphalt. The specialty-formulated adhesive self-seals around nails, crews and other punctures. For a very small investment, PostShield can add years to the life of your pole barn!”

Sounded pretty exciting to me, so I wanted to know more! Going to the PostShield website I found:

PostShield, is a UV impregnated PVC ‘sleeve’ that makes installation, replacement and repair of 4×4 wood posts simpler, faster and safer. It extends the life of posts used for signs, fences, retaining walls…anywhere a 4×4 wood post is used. PostShield is being used by homeowners, fencing contractors, State DOT’s, Parks & Recreation Departments and CalTrans. 

PostShield helps prevent decay and extends the life of wooden posts by creating a barrier between wood and dirt, draining water and venting moisture.

Post replacement becomes quick and easy and you will no longer need to dig out old concrete. Simply pull the old post out of the existing PostShield and slide a new one in. PostShield is a simple, cost effective solution for prolonging the life of wooden posts.”

In reading further on the Post Shield website, it turns out they are ONLY available in one size – to fit a 4×4. Now, other than perhaps for an entry door post, I would hope no one is offering post frame buildings with 4×4 columns!

Apparently the PostShield patent covers a myriad of sizes, however if sizes to fit typical pole building post sizes were made available, for use in pole barns, I see some potential structural concerns.

“The design of the PostShield allows the post to “breathe”. Specially designed ribs on the interior surfaces, the ones that come into contact with the wood 4×4, allow moisture to evaporate away from the post.”

PostShields are placed into concrete in a hole. The idea is to be able to slide a post into the PostShield, with fasteners at the top – into the post, being the only thing resisting wind uplift. It would require a significantly large number of substantially sized fasteners to be able to resist the uplift forces generated by a building of any significant size.


The idea here for a pole building – is that there is a binding value (which can be calculated by the way) between the concrete and earth, and then between the concrete to the post, to create the foundation….and hold the pole building in the ground.  I may offend a few here, but I have to say it…putting a plastic sleeve around a post so it “easily slips out” is like putting a post condom on it.  Talk about negating why you are putting poles in the ground in the first place….to create the foundation.  I have the same opinion of sono tubes – but that’s another day and another blog.

My real issue – why even mention a product as being available, if it is not applicable to the end use?
