There are two types of insulation available for our metal buildings: double bubble insulation for moisture control, and woven R17 insulation for moisture and temperature control. The woven R17 insulation is thicker than double bubble insulation and provides an R-value of R17.

Double Bubble Insulation for Metal Buildings

Double bubble insulation has a silver backing that goes against the sheeting on the building. The other side of the insulation (the side you see) is white. Double bubble insulation is primarily used to control moisture. It prevents condensation on the inside surfaces of the building. It does not provide much temperature control.
The cost of the insulation is $1.50 per sq. ft. of wall and roof area to be covered.
Here is how to calculate the cost to insulate a building that is 12’ to 30’ wide:
Roof: (Width + 2’) x Frame Length x $1.50
Sides: Height x Frame Length x 2 sides x $1.50
Ends: (Height + 2’) x Width x 2 ends x $1.50
For example, if the frame of your building is 12′ x 20′, with sides that are 10′ tall, your cost would be:
Roof: (12 + 2) x 20 x $1.50 = $420
Sides: 10 x 20 x 2 x $1.50 = $600
Ends: (10 + 2) x 12 x 2 x $1.50 = $432
TOTAL: $1452
Please keep in mind that the metal building insulation prices are subject to change without notice.
Woven 17 Insulation for Metal Buildings
The woven R17 insulation is a combination of aluminum foil, bubble material, and woven material which produce the R17 rating.
- Thickness: 17.475 mil – .688″
- Roll Size: 4′ x 98′
- Weight: 45.04 lbs per roll
- Reflectivity: 97%

The woven R17 insulation, which has an R-Value of 17, is the better option for controlling the temperature in your metal building.
The cost of the insulation is $3.00 per sq. ft. of wall and roof area to be covered.
Here is how to calculate the cost to insulate a building that is 12’ to 30’ wide:
Roof: (Width + 2’) x Frame Length x $1.50
Sides: Height x Frame Length x 2 sides x $1.50
Ends: (Height + 2’) x Width x 2 ends x $1.50
For example, if the frame of your building is 12′ x 20′, with sides that are 10′ tall, your cost would be:
Roof: (12 + 2) x 20 x $3.00 = $840
Sides: 10 x 20 x 2 x $3.00 = $1200
Ends: (10 + 2) x 12 x 2 x $3.00 = $864
TOTAL: $2904
The insulation prices for 32′ to 60′ wide metal buildings use a complex pricing formula, so get the insulation cost for a metal building that is wider than 30’, please call Alan’s Factory Outlet at 1-800-488-6903, or email us through our contact us page.
We are happy to price the insulation on any size of metal garages you are looking for.
