Guide to Insulating Your Garage Door: Options & Key Differences
At GDS – Garage Doors & Openers Ottawa, we understand that your garage is more than just a place to park your car—it’s an extension of your home. Insulating your garage door can make a significant difference in energy efficiency, comfort, and even noise reduction. With Ottawa’s cold winters and warm summers, choosing the right insulation for your residential garage door is key to maintaining a comfortable environment year-round. In this blog post, we’ll explore the various types of garage door insulation, their benefits, and how they differ to help you make an informed decision for your home.
Why Insulate Your Garage Door?
Before diving into the types of insulation, let’s quickly highlight why insulating your garage door is a smart choice:
Energy Efficiency: An insulated garage door helps regulate the temperature in your garage, reducing heat loss in winter and keeping it cooler in summer.
Comfort: If your garage is attached to your home or used as a workspace, insulation ensures a more comfortable environment.
Noise Reduction: Insulated doors can dampen outside noise, making your home quieter.
Durability: Insulation adds strength to your garage door, potentially extending its lifespan.
Now, let’s explore the most common types of residential garage door insulation available in Ottawa and their differences.
Types of Garage Door Insulation
There are several insulation materials used in garage doors, each with unique properties, R-values (a measure of thermal resistance), and benefits.
Below, we break down the main options
- Polystyrene Insulation (Expanded Polystyrene – EPS) Polystyrene is one of the most common insulation materials for garage doors, often referred to as “foam board” or “rigid foam.” It’s typically found in single- or double-layer garage doors.
How It Works: Polystyrene is a lightweight, rigid foam that’s inserted into or bonded to the garage door panels. It comes in sheets of varying thicknesses, which directly impact its insulating power.
R-Value: Typically ranges from R-4 to R-7, depending on the thickness.
Benefits:
Affordable and widely available.
Lightweight, so it doesn’t add significant weight to the door.
Provides decent thermal resistance for moderate climates.
Drawbacks:
Lower R-value compared to other materials, making it less effective in extreme Ottawa winters.
It may not provide as much structural strength as other options.
Best For: Homeowners looking for a budget-friendly insulation option for garages that aren’t used as living spaces.
- Polyurethane Insulation – Polyurethane insulation is a premium option, commonly found in high-quality, energy-efficient garage doors. It’s injected as a liquid into the door’s panels, where it expands and hardens to fill all gaps.
How It Works: The foam is sprayed into the garage door’s interior, creating a dense, seamless layer of insulation that bonds directly to the door.
R-Value: Typically ranges from R-12 to R-18, offering superior thermal resistance.
Benefits:
Higher R-value, making it ideal for Ottawa’s harsh winters.
Adds significant structural strength, making the door more durable and resistant to dents.
Excellent at sealing gaps, reducing air leaks.
Provides better soundproofing than polystyrene.
Drawbacks:
More expensive than polystyrene.
Heavier, which may require a stronger garage door opener.
Best For: Homeowners who use their garage as a workshop, gym, or living space, or those prioritizing energy efficiency.
- Fiberglass Insulation – Fiberglass insulation is less common for garage doors, but is sometimes used in custom or specialty doors. It’s typically installed as batts or rolls.
How It Works: Fiberglass batts are placed within the garage door’s frame or panels, often secured with a vapor barrier.
R-Value: Typically ranges from R-8 to R-13, depending on thickness.
Benefits:
Lightweight and relatively easy to install.
Good for noise reduction.
Affordable compared to polyurethane.
Drawbacks:
It can be less effective if not properly sealed, as air gaps reduce its insulating power.
May absorb moisture if not properly protected, which can be an issue in humid conditions.
Not as structurally reinforcing as polyurethane.
Best For: Homeowners looking for a middle-ground option or those retrofitting older garage doors.
- Reflective Foil Insulation – Reflective foil insulation, also known as radiant barrier insulation, is a less common but effective option for specific situations. It consists of a reflective material (often aluminum foil) layered with a backing material like foam or bubble wrap.
How It Works: Reflective foil reflects radiant heat away from the garage, keeping it cooler in summer. It’s typically installed on the interior side of the door.
R-Value: Varies widely, typically R-3 to R-10, depending on the design and installation.
Benefits:
Excellent for reducing heat gain in warmer months.
Lightweight and easy to install, making it a good DIY option.
Often more affordable than polyurethane.
Drawbacks:
Less effective in cold climates like Ottawa’s, as it primarily reflects heat rather than trapping it.
Lower R-value compared to polyurethane or even polystyrene.
Best For: Garages in warmer climates or homes where summer heat is a bigger concern than winter cold.
Key Differences Between Insulation Types
To help you choose the right insulation for your garage door, here’s a quick comparison of the key factors:
Climate: Ottawa’s cold winters make polyurethane or higher R-value insulation ideal for maintaining warmth. If your garage is used as a living space, prioritize polyurethane for maximum efficiency.
Usage: If your garage is primarily for parking or storage, polystyrene or fiberglass may suffice. For workshops or home gyms, opt for polyurethane for better temperature control.
Budget: Polystyrene and reflective foil are more affordable upfront, but polyurethane may save you money in the long run through energy savings.
Door Material: Steel doors pair well with polyurethane or polystyrene, while wooden doors may require custom insulation solutions like fiberglass.
Opener Strength: Heavier insulation, like polyurethane, may require a more powerful garage door opener to handle the added weight.
