Whether you have a regular roof carport, A-frame carport or vertical roof carport, proper insulation is vital for comfort—especially if the area is utilized regularly. While galvanized steel metal roofing his highly resilient to the weather and elements, it is a highly conductive material. Essentially, this reaction is what causes cool weather to permeate the carport in winter and result in scorching summer temperatures. Insulation for metal carports is the best approach to blocking these heat transfers in addition to helping control condensation.
Why Do You Need Carport Insulation?
Unless you like being extra cool or boiling when using your carport for enjoyment, as a workspace, or however you choose, insulation for your metal carport is a must. Be sure to consult with your installer or custom metal building expert about which materials are best for your style and use of the area.
There are three primary insulation types for metal carports and similar structures: reflective / thermal insulation, foam board, and fiberglass.
Radiant Barrier Insulation / Reflective Insulation
Radiant barrier insulation is also known as reflective insulation, and it is best to have this installed when you order a custom metal building or purchase one. This insulation is highly recommended by professionals as a tremendous help with heat transfers. Radiant barrier insulation evenly redirects heat transfers when installed between the frame and interior panels of a metal structure.
If keeping a prized auto paint job or allowing for a cooler RV that someone may be residing in, blocking this heat is not only essential, but it can maximize comfort and lower overall expenses in the long run. You will also want to consider a reflective barrier if your family enjoys hanging out under the shady patio. Insulation will make your experience much more pleasant.
Foam Insulation Options for Metal Carports
This is by far one of the top options for metal carport owners, particularly those who already own one without any type of insulation or who need replacement. Foam insulation provides an impressive amount of thermal resistance, and actually adds a bit of strength to the structure. The R value of these products have the potential to be three times more efficient than fiberglass options.
Those who spend a good deal of time in their carport will appreciate the more comfortable temperatures that come with foam insulation. Depending on the condition, style and size of your metal carport, you might choose between rigid foam boards or spray foam options.
Rigid Foam Board Insulation—The easiest type of foam installation are rigid foam boards that typically come in 4’x8’ sheets. They are easy to cut to fit the structure of any design of carport you might have. Another benefit of foam boards is that can help keep pests, insects and mold at bay.
Spray Foam Insulation—There are a few types of foam applications available, but the best type will depend on the design, layout and age of your metal roofing. For smaller size applications or tight spaces, an aerosol container can be used. However, it is more common to use a pressure sprayer for new and larger carport roofs. Because these are caustic when they are in their finite spray form, it is advised to leave these jobs to professional metal roofers. Furthermore, they can help you decide whether this application method is best for your situation.
Fiberglass Insulation for Metal Roofing
Fiberglass is one of the most commonly known types of insulators that has been used for decades. Fiberglass insulation for metal carport roofing is effective, but not without its constraints. The most important factor in long-lasting heat and cooling resistance with these types of materials is choosing fiberglass that is specially designed for use with steel buildings. Fiberglass crafted for metal installations is made of long fiberglass strands that are woven and laminated on one side to establish a vapor-barrier facing.
Fiberglass basically operates as a form of open cell insulation much like Gore-Tex and neoprene, as the air pockets provide insulation. It is these pockets that can fill up with water when exposed to moisture, causing it to fail in performance as an insulator. However, good quality fiberglass insulation for carports will eventually dry out and regain its effectiveness.
