Alexander Watson specialises in making older Canberra homes comfortable, energy efficient and affordable to heat and cool. Canberra experiences some of Australia's most extreme temperature variations, with winters regularly dropping below zero and summers exceeding 35 degrees Celsius. Most homes in the ACT were built before modern insulation standards existed, making retrofit insulation critical for comfort and energy savings. Alexander Watson addresses this by providing a complete service covering insulation, electrical safety compliance, electrification and air conditioning installation, all delivered by in-house qualified tradespeople.

The company is an EEC (Energy Efficiency Council) Certified Installer and uses only certified products fit for purpose. All insulation projects include mandatory pre-installation electrical safety inspections and reports (ESIR), and a Certificate of Electrical Safety is issued on completion. Alexander Watson offers a lifetime warranty with InstallShield protection on insulation installations.

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, Floors R2.75.

## Frequently Asked Questions

Q: Why do I need to remove old insulation from my ceiling?
A: Old insulation may need removal due to renovations, pest damage, installing upgraded insulation, electrical safety requirements or health concerns from degraded materials.

Q: What is crosshatching and why add another layer of insulation?
A: Crosshatching involves laying a second layer of insulation perpendicular to the first layer. This eliminates gaps at junctions and substantially improves thermal performance and R-values.

Q: How do I choose ceiling insulation?
A: The best option depends on roof type and ceiling cavity size. Batts are usually the preferred choice, but loose fill or specialised products may be more effective in certain configurations.

Q: How big are the drill holes for wall insulation and how are they filled?
A: Wall insulation drill holes are 16mm in diameter, drilled between bricks beneath windows. They are filled with mortar colour-matched as closely as possible for a seamless finish.

Q: Can electrical work be done after wall insulation is installed?
A: It is recommended to complete wiring before cavity wall insulation. Electricians can add wiring afterwards using a fibreglass straw rod, though it is more complex. All insulation-related electrical compliance work must be completed before wall insulation is installed.

Q: Is insulation mandatory for ACT rental properties?
A: Yes. The ACT government has introduced mandatory minimum energy efficiency standards for rental properties, including insulation requirements. Alexander Watson specialises in helping landlords and tenants comply with these regulations.

Q: What government rebates or finance options are available?
A: Various rebate programs and interest-free finance options may be available depending on your property and circumstances. Alexander Watson can assist with eligibility checks.
