Perm Rating

The perm rating, or permeance, is a measure of the amount of water that passes through one square foot of material per hour. The lower the perm rating, the more effective the barrier. A facing material with a perm rating of 0.1 or less is considered excellent. Anything with a rating above 1.0 is not considered a vapor barrier.

Foundations

Do I need a foundation for my metal building? - Some people choose to pour a full slab foundation, however if you're planning on leaving the floor in a dirt or gravel condition, concrete piers will do the job just fine. Please contact a customer service representative if you don't plan to pour a full slab foundation.

Can you provide an engineer stamped foundation layout? - Yes, but in some cases your soil conditions play a major role in the type of foundation you can use. Contact our special sales department for more information. If using a local engineer, we will provide anchor bolt plans to aid your engineer in designing the foundation.

Do you supply the hardware to attach the frame to foundation? - No, the anchor bolts are usually supplied by a concrete contractor and placed when the foundation is poured.

Controlling Condensation

Two things must be present for condensation to occur: warm moist air and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.

In metal buildings, we are concerned with two different areas or locations: visible condensation which occurs on exposed surfaces below dew point temperatures, and concealed condensation which occurs when moisture has passed through the vapor retarder and into interior roof and/or wall cavities and then condenses on a surface below dew point temperature.

Thermal Conductivity (K-Value)

A unit used to express the amount of heat, in BTU's per hour, that passes through one square foot of homogeneous material that is exactly one inch thick and has a temperature difference of one degree Fahrenheit between its surfaces. As the K-Value decreases, so does the amount of heat permitted to pass through the material.

Components/Accessories

Which base trim option should I choose? - The base trim that you choose for your steel building will depend on your building's needs and the type of foundation you use. Although we strongly recommend a notched base, we do offer several additional base trim options to suit your specific needs. Please see base conditions for more helpful information and illustrations.

What type of windows do you offer? - We offer a selection of windows for your building. To learn more about what's available please visit the accessories section of our website.

What comes with the doors and windows? - All of our doors and windows come with the required hardware to install them into your steel building. We provide the framing, trim, and flashing for a proper installation.

How do I know where to place my windows and doors? - Windows and walk doors are generally "field located." You, as the customer, will pick the location, cut the corresponding panel to size and proceed to mount the doors and windows. If you choose to include a large number of windows or doors we may ask you to give us your proposed location to ensure proper building bracing.

How do I attach my doors and windows? - All of our walk doors are self-framing, so they include the necessary items to mount them on your building. Our windows are secured by screwing the window trim directly into the building. This is also known as self-flashing. If you live in a high wind area, please talk to one of our design consultants about additional door and window mounting options.

What is the R-Value of your insulation? - The r-value of our insulation depends on the thickness you choose. It will vary between R-10 and R-19. Please see the r-value section of our website for more helpful information.
