Standard Insulation Roll Sizes
Widths: 4′, 5′, and 6′.
Length: 16′-100′
Tabs: 2-3″ or request 1-6″.
Custom Insulation Roll Sizes
8’ wide facing is available! It is offered only with WMP-30, which is 101”. This would result in (2) 2.5” tabs.
The narrowest facing is 42”, which is typically used for 36” fiberglass, which would give you (2) 3” tabs (one each side) or (1) 6” tab (one 6” and the other side has facing/insulation with no tab).
So, if 24” fiberglass is desired, you would have (2) 9” tabs, due to the use of 42” facing. If someone wants 36” fiberglass…the same 42” facing would be used, but it would result in (2) 3” tabs.
A cut charge applies to 24” and 36” fiberglass. For budgetary purposes, charging the 24” at the 36” price should cover the cost. Same with 36” at the 48” price.
A cut charge applies to length cuts under 16′. For budgetary purposes, approximately $0.4 per ft.
Tape, Banding, and Installation Accessories
Tape, banding, and screws will match the color of the chosen insulation facing. List desired items on the order form.
Double-Sided Tape
$35
3″ x 150′. Recommended one roll per 2,000 square feet.
Double-sided tape is usually applied before installing sheeting. It temporarily holds the insulation in place until the sheeting is installed.
Patch Tape
$35 ($25 for same-day call as order).
1/2″ x 60′. Recommended one roll per 15,000 to patch. If sealing around doors, windows etc., order additional rolls.
Used to repair tears, seal gaps, joints, and seams, ensuring a continuous thermal barrier.
Insul-Holds
$78
100′ in length
These hangers will keep the heavier vinyl-faced insulation R-values from sagging in the cavity over time.
Has hooks (arrow prongs) spaced every 8″ inches on center.
Banding
$175
One roll of 500′ banding per 1,000 square foot of coverage.
This is usually bought when installing vinyl-faced insulation in a retrofit project. It helps prevent the insulation from sagging and shifting.
Fiberglass vs Spray Foam vs Reflective Insulation
All insulation types have their market niche, as well as pros and cons. Factory Steel Overstock could offer every insulation type; however, it to offers what the most cost-effective insulation for metal buildings and pole barns, which in fiberglass vinyl faced insulation.
Fiberglass Vinyl faced Insulation vs Spray Foam
COST:
One of the most expensive insulation options on the market is Spray foam. Unlike fiberglass, which is a popular DIY material due to its ease of installation, spray foam is far more labor-intensive and usually requires professional application. With a metal building, a layman simply rolls the vinyl-faced insulation over the purlins and girts, then pins it down while installing the sheeting material. Although Spray Foam may offer a higher per square foot thermal efficiency than fiberglass viny faced, one has to consider the additional initial investment required.
HEALTH FACTORS:
One must also consider that the chemicals used in spray foam can release toxic gases if not installed properly. That is not an issue with fiberglass vinyl-faced insulation. It is imperative that one verifies that the space being insulated is well-ventilated and that all safety measures are implemented during installation.
EXPANSION:
Fiberglass Vinyl-faced insulation is not going to expand; however, the nature of spray foam is to expand as it cures. This can sometimes lead to unwanted pressure on drywall and framing if not closely watched during installation.
Fiberglass Vinyl-faced Insulation vs Reflective
Effectiveness in Cold Climates
Reflective insulation is designed to reflect radiant heat away from your metal building or pole barn; therefore, it is an ideal insulation type in hot climates. Its primary purpose is to keep your structure cool; however, most locations require insulation to address climate conditions for all seasons. In other words, an insulation that also deals with winter temperatures. Reflective insulation has a limited ability to resist heat flow, which makes it less effective in cold climates. For this reason, fiberglass vinyl-faced insulation is a more practical choice.
Airspace Installation Requirements
Simply put, reflective insulation requires a gap to be effective, and there are situations where this may be a challenge during installation. This is not a requirement with Fiberglass Vinyl-faced insulation.
Although all insulation types have their market niche, pros and cons, fiberglass vinyl-faced insulation is the most preferred type for DIY projects. Ready buyers, call 1-888-512-1116.
