Keep Your Garage Warm, Quiet and Efficient

Garages are often one of the coldest and least insulated parts of a home, yet they can have a big impact on overall comfort and energy use. Whether your garage connects directly to your living space or sits beneath a bedroom, adding proper garage door insulation can make a noticeable difference to warmth, noise and efficiency. At Heartland Insulation, we install tailored garage insulation systems designed for South Island homes and conditions.

Why Insulate a Garage Door?

  • Polyester Panel Inserts – Lightweight, non-irritant and moisture-resistant panels that fit directly into sectional garage doors for an instant thermal upgrade.
  • Polystyrene Rigid Boards – High-performance insulation sheets that deliver excellent R-values and a clean, professional finish. Ideal for larger or commercial garage setups.
  • Acoustic & Thermal Liners – Designed to minimise both temperature changes and external noise, improving comfort in converted or multi-use garages.
  • Door Seal & Draught Stoppers – Fitted around edges and bottom gaps to prevent cold air and dust ingress, ensuring a complete insulation system.

Benefits of Garage Door Insulation

  • Reduce energy loss and heating costs

  • Minimise condensation and protect tools or storage

  • Lower outside noise and vibration

  • Enhance property value and compliance for rentals
