Insulated Sectional Doors

Why Choose a Dominator Insulated Garage Door?

An insulated garage door improves comfort, reduces noise, and helps make your home more energy efficient.

Dominator insulated sectional doors are factory-built with high-performance insulation, delivering reliable temperature control, quieter operation, and long-term durability for New Zealand homes.

Benefits of an Insulated Garage Door for Families

• A Warmer, More Comfortable Garage
  Insulated garage doors help reduce heat loss, keeping your garage warmer in winter and cooler in summer. This is especially important for attached garages or spaces used as playrooms, home gyms, or workshops.
• Quieter Living Spaces
  Insulation acts as a two-way noise barrier. It helps reduce street noise entering your home while also minimising sound from inside the garage, creating a calmer, more comfortable environment.
• Improved Safety and Security
  Every Dominator sectional door is custom-built for a precise, secure fit. When paired with a SMART opener, you can enhance your home’s security and access convenient features like remote monitoring via the Dominator App.
• Long-Term Peace of Mind
  Selected door and opener combinations are eligible for our 10-Year Total Confidence Extended Warranty, giving you confidence in long-term performance and support.

Benefits of an Insulated Garage Door for Renovations

• Increase Property Value and Street Appeal
  A new insulated garage door enhances the overall look of your home while improving energy efficiency, two key factors for modern renovations and resale value.
• Flexible Design Options
  Choose from a wide range of styles, colours, and finishes to match your home’s design. Dominator doors are made to order, ensuring the right fit for your renovation project.
• Create a More Usable Space
  An insulated garage is more comfortable year-round, making it easier to use the space for storage, hobbies, or additional living functions.
• Future-Proof Your Home
  Improved thermal performance and reduced noise help ensure your garage remains practical and valuable well into the future.

Why Factory-Fitted Insulated Garage Doors Perform Better Than Retrofit Options

• Engineered as a Complete System
  Dominator insulated doors are designed and manufactured as a complete door system. The insulation is integrated during production to ensure correct balance, structural integrity, and consistent performance.
• Consistent Thermal and Acoustic Performance
  Factory-fitted insulation is evenly distributed within the door panel, helping deliver reliable temperature control and noise reduction across the entire door.
• Durability Built In
  Our polyester insulation is thermally bonded and contains a minimum of 50% recycled materials. It is BRANZ Appraised, GreenTag certified, and designed for long-term durability.
• Designed for Long-Term Reliability
  Because the insulation is fitted at the time of manufacture, the door is built to operate correctly with the added weight and structure—supporting smooth operation and consistent performance over time.
• Covered by Warranty
  Factory-fitted insulation forms part of the original product configuration and is covered under Dominator’s Standard and Extended warranty offerings, where applicable.
