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.

COMMERCIAL OFFICES

Your place of business should and can be more than just a place to work. It should reflect your company's image and be no less comfortable, functional or attractive than your living environment. Entry-ways and lighting, interior wall placement, and location of restrooms are as important in your office building as they are in your own home. Properly planned, your facility will serve your needs for many years to come, and you will avoid future changes or costly remodeling.

Modern ceiling and interior wall systems are very easily adapted to our manufactured building components using standard methods. For instance, perimeter sheet rock walls may be installed by simply attaching metal furring strips (hat channel) to the secondary wall framing members (girts). Similarly, acoustic panel or dry-wall ceilings may be installed by simply wrapping the ceiling suspension wires around the secondary roof framing members (purlins). Additionally, port-a-wall systems may be installed as needed throughout the structure.

Additional loads from heating and air conditioning systems, dropped ceilings, electrical conduit and lighting fixtures, or large mechanical sprinkler systems can be accommodated easily at your request with minimal cost, assuring a full roof-load certification.

The building components may represent a small percentage of the total cost of your office budget. Therefore, we are careful to ensure that the main structural components we provide will be reliable, helping to protect your investment against any water seepage, leaks or storm damage that can deteriorate your office complex.

When selecting the manufacturer of your building components, careful consideration must be given to both function and price. Your dealer will encourage you to have an architect review all aspects of your building plan, including lighting requirements, window heights, storage space, carpet wear ability, entrances, landscaping, parking and signage, to ensure you of a facility that will maintain its value and be a source of pride for years to come.

Other Metal Building Details

Fasteners: Self-drilling fasteners are designed for rapid drilling without slipping of the drill point, thus reducing walking and surface marring. The neoprene washer keeps your building watertight as well as providing vibration dampening.

Structural Bolts: We provide all the nuts and bolts to assemble your building through pre-punched holes.

Closure Strips: Our Steel Buildings come with closure strips which when installed provide weather tightness. The closure strips are pre-formed to match the profile of the panels.

Ridge Cap: The ridge cap is designed to match the slope and contour of the roof providing a tight seal along the ridge of the building.

Trim, Flashing, Gutters & Downspouts: All our buildings come with standard trim to give the building a finished clean look. Optional Gutters and Downspouts provide additional protection from the elements.

Plans and Drawings: We provide a full set of anchor bolt plans for the placement of anchor bolts in the foundation. We also provide engineered stamped and certified construction prints. In addition we provide an in depth erection manual to walk you through the erection of your building.

Thermal Conductance (C-Value)

A measure of the amount of heat that passes through materials of any thickness.

Calculated Thermal Values

Basically it is the reciprocal of the calculated U-Value. By definition it is the summation of all the R-Values for each of the building's components. This method of calculation does not consider the thermal short circuit effect of structural members, fastener population or the compression of the insulation at its structural members. It should also be noted that this type of calculation often indicates heat loss values for building envelopes that are lower than those actually found in the finished structure.
