DIY Insulation FAQs
Q: Can I install insulation myself?
A: Yes! With the right tools and guidance, DIY insulation is achievable. We recommend starting with ceiling and wall insulation for maximum impact.
Q: What is an R-value and why does it matter?
A: R-value measures thermal resistance. The higher the R-value, the better the insulation. NZ Building Code sets minimum R-values by region.
Q: Where should I insulate first?
A: Prioritize the ceiling and roof, followed by walls and floors. These areas offer the greatest thermal and financial benefits.
Q: Do I need a vapor barrier?
A: In damp-prone areas like underfloor, yes. Vapor barriers help prevent moisture buildup and mold.
Q: How do I calculate how much insulation I need?
A: Measure the area (length × width) of your space, subtract windows and doors, and match the coverage to product specs.
