PGD Pre-Cut Garage Door Insulation Panels (600 x 1200mm)

Keep Warm This Winter with New Zealand's Highest Rated Garage Door Insulation

Premium Garage Doors (PGD) Pre-Cut Insulation Panels are the easiest way to insulate your sectional garage door while keeping freight costs down.

Manufactured in New Zealand from premium high-density polyester fibre, these pre-cut 600 x 1200mm panels are the same professional insulation product we install every day throughout New Zealand, simply supplied in a convenient pre-cut format that's easier to install and more affordable to ship.

Designed to suit 25-45mm sectional garage doors, these panels provide outstanding thermal performance, noise reduction and a clean factory-style finish.

Unlike imported stick-on rubber mats that trap moisture and eventually fall off, or polystyrene products that squeak, crumble and deteriorate over time, PGD insulation is rigid, non-toxic, moisture resistant and purpose-built for New Zealand conditions.

This is exactly what the professionals use. It's the only insulation solution we recommend and install ourselves.

Pre-Cut or Full-Size? You Choose

This listing is for our pre-cut 600 x 1200mm insulation panels, designed to make installation easier while significantly reducing shipping costs.

The insulation itself is exactly the same premium New Zealand-made product as our full-size sheets—it's simply pre-cut into smaller panels for easier handling, installation and more affordable freight.

If you would prefer fewer joins, have an oversized garage door, or would rather cut the insulation yourself, we also offer full-size 1200 x 2400mm insulation sheets in a separate product listing. Simply browse our garage door insulation range to choose the option that best suits your project.

Ideal for garages used as:

• Workshops
• Home gyms
• Storage areas
• Hobby rooms
• Home businesses
• Extended living spaces
