Features of Insulated Garage Doors
Insulated garage doors are typically built with a multi-layer design, which provides added durability. They frequently combine outer skins of steel, wood, or composite with insulating cores of polystyrene or polyurethane.
This unique construction improves thermal efficiency, keeping the temperature in your garage more consistent, even when it’s sweltering hot or bitterly cold outside. An insulated door functions like a winter coat by blocking the cold air from coming in. It’s like sunscreen, shielding your space from unbearable heat.
These doors provide LEED homes with tangible energy savings through less wasted heating or cooling. An R-value is a measure of thermal resistance. The R-value for the whole door assembly is a mere one-third of the panel’s center value.
Every little improvement helps a lot! A door rated R-16 insulates roughly 5% better than one rated R-8, providing measurable comfort improvements. Soundproofing is another main benefit. Insulated doors reduce noise from both street traffic and the door’s operation, making them ideal for homes near busy roads.
Aesthetic options include a wide variety of colors, textures, and finishes, allowing you to match the door to your home’s design while maintaining functionality.
Features of Non-Insulated Garage Doors
Non-insulated garage doors have a simpler design and are typically made from a single-layer material. They tend to be more affordable compared to insulated options. However, they offer little to no energy efficiency, which can impact heating and cooling costs. These doors also provide minimal noise reduction and may contribute to increased operational sound. Despite these limitations, they are available in various styles and can be a suitable choice for homeowners looking for a budget-friendly option.
Key Differences Between the Two
One of the biggest differences is energy efficiency. Insulated doors help maintain a more consistent temperature in your garage, reducing the need for heating and cooling. Non-insulated doors are less effective at keeping external heat or cold out.
Insulated options are far more ideal for areas that experience extreme winters or summers. When it comes to minimizing noise, insulated garage doors win the battle against their non-insulated competitors.
The multi-layered construction absorbs sound, giving you a quieter garage. Durability varies too—insulated doors are less prone to dents and damage, giving them longer lifespans and better curb appeal.
Lastly, insulated garage doors increase your home’s comfort. This helps you turn your garage into a temperature-controlled space, ideal for a workshop, gym, or extra living space. They make the garage a flexible, livable extension of the home.
Benefits of Garage Door Insulation
