What are some benefits of insulating a metal building?
If your building is heated or cooled, the primary benefits are energy savings and user comfort. Other benefits include noise reduction, enhanced light reflectivity, and condensation control.
How much insulation should I use?
In a heated or cooled building, installing the highest R-value (thickness) packages available is usually the best way to go. While the pay back through energy savings may have been 7 to 10 years in the past, the high cost of energy in today’s world means the pay back period could be cut by as much as 2/3. The most common “R” values are R-30 in the walls and R-40 in the roof. 6 inch insulation is very common but the buyer needs to be aware that if the insulation is not thinned out over purlins or girts a “pillow effect” may occur causing panel distortion or bulging. If you desire a higher R-value or need to meet a certain commercial code, you have the option to go to a banded system which places the insulation in between the purlins and not as much between the panel and purlin.
What does insulation do?
Metal building insulation acts as a barrier to slow down the movement of heated or cooled air, reduces energy consumption, helps prevent condensation, absorbs sound, and increases lighting efficiency.
What is R-value?
R-Value is a measurement of the effectiveness of an insulator to retain or retard the loss of heat flow. The R-value is directly related to the fiber glass thickness. The thicker the fiber glass blanket the higher the R- value. All R-values listed are determined with the insulation uninstalled. Compression of the purlin install method will reduce the R-values listed. Note: Improper installation of any insulation can significantly lower the insulations effectiveness.
How should the insulation be stored once it arrives at the job site?
Insulation should be stored in a dry protected area especially if it is not to be installed immediately. All poly bags should be elevated as to not become in contact with surface water. Poly bags should have punctures in each end to help allow for circulation.
What should I check for when unloading at the time of delivery?
The insulation should be inspected upon arrival to insure that your order is exactly what was ordered. Take care as to not inadvertently puncture the poly bags while unloading. Seal any tears that may have occurred during the shipping process. If there is anything wrong with the order or insulation then it should not be installed. Contact us immediately! Your insulation comes with a limited warranty. Items not subject to claim under our warranty include reimbursements for consequential damages, labor or rental equipment costs or losses resulting out of a warranty claim.
How is my insulation packaged?
Your insulation is pre-cut for the walls and roof and placed in heavy poly bags for added protection. The bags are labeled. When we say pre-cut we do not mean that there is no field work. For example there may be angles to cut for the end wall. Also, there may be several runs from the base to the eave in one roll. The length of the roll is usually a multiple of the eave height (plus one foot extra to be trimmed).
What does thermal tape do?
Thermal tape is a self-adhesive tape that is placed between the outside girts and the wall sheeting in order to provide a thermal break or barrier. Thermal tape prevents condensation from occurring on the inside of the building. (See Figure 9)
Which are the most common vapor retarders used?
VRR-Plus for the walls and roof. Usually applied when the insulation will be cover with liner panels.
WMP-50 for the walls and roof. Stronger than the VRR-Plus and is applied without the use of liners on the ceiling and partial liners on the wall eight feet high to prevent punctures.
ES (Energy Saver) System for the walls and roof. Strongest material available and is applied without the use of liners on the ceiling and partial liners on the wall eight feet high to prevent punctures.
