Double Bubble Foil-Faced Bubble Wrap

Double bubble consists of two layers of reflective aluminum foil and air bubbles sandwiched between them, creating a strong barrier against heat transfer.

In addition to providing excellent thermal protection, double bubble foil-faced bubble wrap insulation can also reduce noise levels and help prevent the transfer of heat between different objects in tight spaces such as cold water pipes.

This product is easy to install and requires no special tools or skills, making it ideal for do-it-yourselfers.

To get the most out of this insulation, make sure you use double-sided tape when installing it to ensure proper adhesion and avoid gaps in coverage that could lead to energy loss.

With proper installation and maintenance, double bubble foil-faced bubble wrap insulation can be a great option for your metal building project.

Radiant Barrier Sheets

Radiant barrier are made of lightweight aluminum and feature a reflective surface that helps to reduce heat gain and keep the interior of your structure cooler in the summer months.

In addition to reducing energy costs, radiant barrier sheets can also protect against mold growth, dust accumulation, and excessive condensation.

Installing these sheets is relatively easy and doesn’t require any special tools or skills. Simply measure the area you want to cover, cut the sheet according to your measurements, then attach it firmly with screws or tape.

It’s important to remember that radiant barrier sheets should be installed on the interior side of your steel building for optimal efficiency. With proper installation and maintenance, radiant barrier sheets can provide superior insulation in your metal garage.

Garage Door Insulation

Garage doors are typically the largest non-insulated surface in a home, so insulating them will make your garage feel more comfortable overall. 

In winter, uninsulated garages can drop below freezing, while summer temperatures can soar. While a new insulated garage door will have the most significant impact, the cost is usually too much for most homeowners. 

A quick win is to add garage door insulation to your existing door. 

Garage door insulation kits can be added to new or existing garage doors. Usually made of foam or reflective barriers, these kits offer R-values between R-2 and R-8. Compare this to a new insulated garage door ranging from R-6 to R-19.

Insulating the garage door, combined with weatherstripping and insulating other garage areas, can increase indoor temperature by 10 to 12 degrees in winter.
