Eave Lights, Building Plans, and Foundations

Today Mike answers questions about eave lights, drawing building plans, and foundation plans.

DEAR POLE BARN GURU: How to I attach the poly eave lights to the building frame? RUSSELL in BOISE

DEAR RUSSELL: Polycarbonate panels are best predrilled for screw fasteners using a 3/8” bit. Screw pattern for eave lights is same as for sidewall steel.

Drive #10 x 1” white screw fasteners perpendicular to light panel’s surface and tighten moderately. Fastener head and washer/gasket is to sit snugly and fully on panel’s face, without squeezing gasket and distorting washer. Over tightening will distort washer, panel and ruin gasket, causing leaking and panel damage, resulting from undue internal stresses. Tilted fastener insertion will deform washer, damage gasket, cause leakage and originate undue stresses on panel eventually leading to failure. Tighten fasteners by hand or by an adjustable torque power-screwdriver.

Engineer sealed pole barnDEAR POLE BARN GURU: I’m have a question related to the construction of a custom building. I see that you have some sample building plans on your web site. Do you typically produce the plans for the buildings that you construct or do you recommend that a client work with an architect to have plans drawn up before accepting a construction project? If you do recommend that clients provide plans, do you have a list of architects that you prefer to work with?

Thanks in advance, MATTHEW

DEAR MATTHEW: We (Hansen Pole Buildings and our contracted third-party engineers) produce plans for post frame building kit packages we provide. For clients who feel more comfortable working with an architect, we would recommend contracting their services for conceptual work (aesthetics, room layouts and sizes, etc.) and leave structural aspects (permit/construction plans) to our team.


DEAR POLE BARN GURU: Do you have any experience with anchoring a building to an existing slab?

I talked with you before about door options, but now have ran into the problem that the building I am going with will now sit on the anchor plates that I had installed in the slab. Just curios if you know what my best options could be for anchor bolts. Thanks. MICHAEL

DEAR MICHAEL: All steel buildings usually do not come with engineering for a foundation. You are going to have to consult with your foundation engineer and get a fix from them, as no one else can legally make this change.







Triple Wall Polycarbonate Panels

There is never a dull moment in the post frame (pole) building industry. Clients are seemingly forever asking for new and different products to incorporate into their structures – which keeps life very, very interesting.

Multiwall PanelsHansen Pole Buildings recently had an inquiry from a client who wants to construct a greenhouse 24’ wide by 30’ long with eight foot sidewalls. The client specified the use of triple wall polycarbonate panels for roofing. Since I was unfamiliar with the product, it was research time.

We already purchase pallets of precut CoverLite® polycarbonate panels for use as eavelights from Amerilux, so my research began with contacting our friendly sales person there – Stephanie. She proved to be a wealth of information.

The brochure on CoverLite® Multiwall Polycarbonate panels can be viewed here: https://www.ameriluxinternational.com/SideBarLinks/Brochures/coverlite_multiwall_brochure.pdf

Now the use of these panels for roofing (or siding) takes a little more thought than applying traditional roll formed steel panels.

To begin with, these panels have no shear strength, they are not designed to be able to withstand the lateral forces applied to a building. This means the building itself must be reinforced to take the loads. The easiest method is to utilize steel strapping in an X pattern between the pole building framing and the triple wall panels. The strapping needs to be sized adequately to withstand tension forces and most importantly – fastened at each end sufficiently.

For information on steel strapping: https://www.strongtie.com/products/CFS/CS-CMST.asp

In the case of this particular client’s building – the dimensions were fairly small (24 feet wide by 30 feet long and an eight foot eave), so the strapping needs were fairly minimal. As building dimensions increase (or wind load forces to be resisted become more extreme) the strapping must be increased in strength. Shear forces are higher as the endwalls are approached, so strapping sizes and fasteners can be adjusted to meet the requirements of each subsequent bay.

The CoverLite® Multiwall Polycarbonate panels are square, so they do not afford an overlap. The seams between each panel must be joined by means of an H profile trim. As the ends of each panel are open, a U trim must be installed at the top and bottom of each panel, to help prevent moisture from accumulating between the layers. The U at the eave side of the panels must have holes strategically placed to allow for any condensation to run out the low end of the panel.
