The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

In some cases, a detached garage can be considered extra living space, but you will need to gain permission and comply with your local building code. Depending on where you live, you may need permits for a variety of installations, including electrical work, plumbing, and structural work. Many homeowners make the mistake of converting a garage into a living space without acquiring permits, which can result in hefty fines and even the removal of your hard work. Furthermore, a detached garage doesn’t add to the livable square footage of your home when it’s time to sell.

It’s not safe to install a pet door on your garage door. Garage doors that tilt upward can roll up with your dog inside the door without you realizing it, making them dangerous and potentially deadly. Most dog doors also won’t fit on traditional garage doors, as they would need to span the panels, compromising the door’s stability.

Electric garage doors are secure when adequately installed and maintained. They often come equipped with safety features like rolling code technology that generates a new code each time you use the remote, making it harder for burglars to intercept and duplicate. However, their security depends on factors like the quality of the door and your diligence in safeguarding remote controls and access codes. Regular maintenance, strong passwords, and adding security enhancements can boost the security of electric garage doors, making them a reliable choice for many homeowners.
