# Insulation and Energy Efficiency

## Insulation & Energy Efficiency Guides

An uninsulated garage door is one of the biggest energy leaks in an Australian home — especially if your garage is attached to your living spaces. This section covers how insulated garage doors work, when they're worth the investment, and which B&D options deliver the best thermal performance.

### Why Garage Door Insulation Matters

**Temperature Control** — An insulated garage door can reduce temperature extremes inside your garage by 10-15°C. That matters if you use your garage as a workshop, gym, home office, or if it shares a wall with your living areas.

**Energy Bills** — Heat transfer through an uninsulated garage door forces your home's heating and cooling system to work harder. Insulated doors reduce this thermal bridge, particularly in climates with hot summers or cold winters.

**Noise Reduction** — Insulated panels are significantly quieter during operation and block more street noise. If your garage faces a busy road or you open your door early in the morning, insulation makes a noticeable difference.

### What We Cover

**R-Value Comparisons** — Not all insulation is equal. We compare the R-values of different B&D door options and explain what the numbers actually mean for your comfort and energy savings.

**Polyurethane vs Polystyrene** — The two main insulation types used in garage doors, with different performance characteristics and price points.

**Climate-Specific Recommendations** — Whether you're in tropical Queensland or chilly Melbourne, we help you decide how much insulation is worth investing in for your specific climate zone.

Practical advice to keep your garage — and your home — more comfortable year-round.
