Wall Installation

Labels on wall insulation rolls indicate the length as well as the number of pieces that need to be cut from each roll. We recommend that all rolls be cut from a clean location to avoid staining the insulation facing.

1) Cut the dimensions of the insulation from the base angle to eave strut or rake plus 6"-12" extra.

2) Attach one end of the insulation to the base angle using double-faced tape.

3) Pull from the other end to stretch the insulation tightly outside the girts to the eave or rake, and attach with double-faced tape.

4) Make sure the facing is toward the interior of the building and attach the panel to the structure.

5) Install the next roll in the same manner, with edges butted snugly. Then fasten the tabs using one of the methods described.

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.

When you decide to buy a Building

Confirm the accuracy of your building codes. It is imperative that your building conforms to the state, local and federal design requirements.

The items described on your contract are what you are buying. Please be sure to carefully review all contract documents before you sign off. If a contract does not describe an item in specific terms, you should not expect the item to be the best product available. And just as important - is what a contract does not say. Specifically if your contract does not indicate that you are getting framed openings and garage doors - then you are NOT going to get framed openings and garage doors.

Do not sign a contract or agree to purchase a building before you have confirmed that your building will satisfy the requirements of your local building official and YOURSELF. Do not allow a salesman to pressure you into a "panic buy." A "panic buy" is when a customer is pressured into making a purchase to "lock-in" a "so-called" special price. Brokers are notorious for telling customers they could lose an opportunity to get the "deal of a lifetime" if they don't commit to the order right away. Beware of people who urge you to sign a contract before you have made your mind up on exactly what you want.

Understand that making changes after the sale will cost you money. Once the design is completed it will cost money to make changes. If an order is in fabrication - and requires modifications due to customer demands - the entire process has to be stopped, pulled off-line and inventoried. Once the inventory of completed items is confirmed, it's back to the drawing board. You will be responsible for extra time required to re-design the project and all other associated expenses.

Install your building components as specified by the drawings. Seldom do manufacturers use the same design practices and therefore your erection drawings and installation documents are the correct description of the building. Please read and follow the drawing descriptions carefully. An erection manual offers important general guidelines and the proper procedures for erecting a steel building safely. You, your erector and all jobsite crew need to understand and utilize OSHA and all other safety guidelines.

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 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.
