Garage Door Insulation

The Complete Guide to Garage Door Insulation in the UK

Garage door insulation is a cost-effective solution to improve energy efficiency, reduce heat loss, and maintain a comfortable temperature in your garage throughout the year. Whether you use your garage as a workspace, storage area, or home gym, insulating the door can significantly enhance its thermal performance and reduce your energy bills.

Why Insulate Your Garage Door?

An uninsulated garage door is a primary source of cold bridging, allowing cold air to enter and warm air to escape. This can lead to increased heating costs and discomfort during colder months. By adding insulation to the door, you can:

• Reduce heat loss by up to 70%

• Keep your garage warmer in winter and cooler in summer

• Prevent condensation and dampness

• Minimise noise from outside

• Improve the overall thermal performance of your home

Types of Garage Door Insulation

1. Foil Insulation

   • Superfoil garage door insulation offers highly reflective multifoil insulation designed to bounce radiant heat back into the garage.

   • Bubble foil insulation creates an additional thermal barrier.

   • Lightweight and easy to install with double-sided tape or adhesive.

2. Foam Insulation

   • Closed cell foam provides excellent thermal insulation and is often included in insulation kits.

   • Easy to cut and fit, offering a cost-effective way to insulate the door.

3. Insulation Sheets

   • Rigid foam insulation sheets or insulation rolls can be attached to the interior of the garage door.

   • Insulated garage door panels are designed to fit standard up-and-over garage doors or sectional doors.

How to Insulate a Garage Door

Installing garage door insulation is a straightforward DIY project. Follow these steps to ensure the best results:

1. Clean the Door Surface

   • Ensure the garage door is free from grease, dirt, and debris. This step is critical to allow the adhesive to stick properly.

2. Measure and Cut

   • Measure the door panels and cut the insulation sheet to fit each section.

5. Check for Obstructions

   • Ensure the insulation does not interfere with the lifting mechanism or door operation.
