What R-value insulation do I need for my Canberra home?

According to the National Construction Code, minimum system R-values for a typical Canberra brick veneer home with suspended timber floors are: Ceilings R5.1, Walls R2.8, and Floors R2.75. Alexander Watson can assess your specific home and recommend the optimal R-value for maximum energy efficiency.

How long does insulation installation take?

Installation time varies depending on the size of your home and type of insulation. Most residential ceiling insulation jobs can be completed in one day. Wall insulation for an average home typically takes one to two days. Our team will provide a specific timeframe during your quote.

Do you offer interest-free finance for insulation?

Yes, Alexander Watson offers a range of interest-free finance options to help fund your insulation and electrification project. Contact us to learn about available payment plans and check your eligibility.

Are there government rebates available for insulation in the ACT?

Yes, there are rebates and funding assistance available for eligible homes in the ACT. Use our Rebate and Assistance Eligibility checker on our website to see if your home qualifies for support towards your insulation and electrification journey.

What is the difference between spray foam and batt insulation?

Batt insulation is typically used in ceiling cavities and comes in pre-cut panels. Spray foam insulation is applied as a liquid that expands to create an airtight seal, ideal for underfloor insulation and irregular spaces. Spray foam provides superior draught sealing and adheres permanently, while batts may sag over time. Our team can recommend the best option for your specific application.

Do you service areas outside Canberra?

Yes, Alexander Watson services a wide region including Canberra, Sydney, the Riverina, Wagga Wagga, Griffith, Albury, Queanbeyan, Goulburn, Yass and surrounding areas. Contact us to confirm service availability in your location.

Why do I need an electrical safety inspection before insulation?

An electrical safety inspection is required before insulation installation to identify any unsafe or damaged wiring, incorrectly rated circuits, and to assess whether a Residual Current Device (RCD) is needed. This protects your property from fire hazards and electrocution risks. Alexander Watson has in-house licensed electricians who can complete this inspection.

What is cross-hatching insulation?

Cross-hatching is a technique where two layers of insulation batts are installed at right angles to each other. This eliminates thermal bridging through ceiling joists and significantly improves overall insulation efficiency. Instead of a single high R-value layer between joists, cross-hatching uses two moderate layers that cover the entire ceiling including the timber framework.

Can spray foam insulation help with squeaky floorboards?

Yes, one of the significant benefits of underfloor spray foam insulation is that it eliminates floorboard squeaks. The foam adheres directly to the underside of the floor, stabilising the boards and creating a solid, quiet surface underfoot.

Do you use thermal imaging to verify insulation installation?

Yes, Alexander Watson uses real-time thermal imaging to verify wall insulation installations. This technology ensures 100% thermal coverage with no gaps, and we provide a gap-free guarantee backed by thermal imaging verification.
