Your geographic area will, to a great extent, influence the type of insulation that will provide the best performance. If you live in a mild climate and your building is used for farm equipment storage, insulation may not be necessary. If you are planning to have employees working in a building, you should probably install insulation, particularly in areas where temperatures are extreme. Energy savings will quickly pay for insulation if the building will be climate controlled.
Recommended Installation Methods of Insulation
Roof insulation rolls are cut to lengths that will cover the distance from eave to eave, leaving a one-foot overhang on each side of the building.
1) Start at the end of the building and temporarily secure one end of the roll by attaching the insulation to the eave strut with double-faced tape.
2) Pull the insulation across the purlins with the vapor barrier toward the building interior. Double-faced tape attached to the opposite end of the insulation will keep tension on the roof roll while the metal panels are being attached over the insulation.
3) Install the next roll in the same manner, making sure the rolls are stretched tight, aligned properly and closely butted.
4) Fasten tabs using one of the methods described on the following page. Any rips or tears must be covered with matching facing tape to ensure a tight vapor seal.
5) Trim excess insulation flush to prevent it from acting as a wick and moving water into the building.
Facings as Vapor Barriers
The main function of facings is to act as a vapor barrier. While a vapor barrier may not necessarily be able to stop the flow of water vapor, it does an excellent job of minimizing the rate and volume of the flow. This prevents moisture from accumulating within the insulation blanket and the structure, which translates into consistent thermal values and lower heating and cooling costs.
Facings intended to serve as vapor barriers should be installed on the inner, heated surface of the insulation, where vapor pressure is the highest. This helps in preventing vapor from reaching the cooler air and condensing.
VAPOR BARRIERS PREVENT VAPOR FROM REACHING COOLER AIR AND CONDENSING.
Thermal Conductance (C-Value)
A measure of the amount of heat that passes through materials of any thickness.
Every metal building has some type of base connection along the building perimeter, allowing the connection of sheeting. This "base condition" determines exactly how the panels connect to the foundation. To prevent water and pests from entering the building at the base, panels extend below the finished floor of the building. Online design and pricing systems allows users to choose from a number of different base options.
Standard Base Angle - Our system defaults to a standard base angle condition. This condition consists of a single angle member, attached to both the wall sheets and the slab. Please note that the standard base condition requires that the slab be formed with a 1˝" sheet notch to allow the sheets to extend below the top of the slab.
Deluxe Trim - Deluxe base trim is another option for buildings with concrete slab foundations. Deluxe base trim combines base angle and trim into one piece, providing all the benefits of base trim and base angle. Deluxe base trim is only available in burnished slate color.
Base Girt - The base girt option is designed for buildings that sit on piers rather than a full slab. A base girt system does not rest on or attach to the foundation. The base girt attaches to clips on the columns about 6" above the foundation. The base girt provides a great connection for liner panel.
Base Channel - The Base channel is a "cee" shaped section that runs the perimeter of the building connected to the floor. It is most commonly used when a liner panel, or interior wall, is going to be installed. The "cee" section provides a pre-positioned connection point for inside panels. This approach requires a sheet notch in the slab (for an alternative, see the combination of base channel and base trim below).Thank you for visiting Premier Steel Building.
