Retrofitting Insulation for Existing Homes & Rentals

Southtile Insulation – Your Local Retrofit Experts in Canterbury & Southland

Why Retrofit Insulation Matters

Many older New Zealand homes—especially those built before 2000—lack proper insulation. That means:

• Cold winters and sweltering summers

• Higher energy bills

• Increased risk of dampness, mold, and health issues

Retrofitting insulation transforms your home into a comfortable, energy-efficient, and healthier space. Whether you're a homeowner or landlord, Southtile Insulation makes the process easy, affordable, and compliant with NZ standards.

What We Offer

Ceiling Insulation: Your First Line of Defense

Heat rises—and escapes through your roof. Installing or topping up ceiling insulation is the most effective way to retain warmth.

• Rated by R-value (thermal resistance)—higher is better

• Meets or exceeds NZ Building Code standards

• Ideal for homes with existing but outdated insulation

Underfloor Insulation & Moisture Barriers

Even dry-looking subfloors can trap moisture. We install:

• Underfloor insulation to block cold air

• Ground vapour barriers to prevent dampness and mold

• Solutions tailored to homes with enclosed perimeters and crawl space access

“Improves indoor air quality and protects your home’s structure”

Insulation FAQs

Q: Does insulation really make a difference?

A: Yes! Up to 40% of heat escapes through the roof, 24% through walls, and 10% through floors. Proper insulation slashes energy bills and improves comfort.

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: Do I need consent to retrofit insulation?

A: No consent is needed for ceiling or underfloor retrofits. External wall insulation may require consent depending on the method.

Q: Can insulation improve my home’s value?

A: Absolutely. Energy-efficient homes are more attractive to buyers—90% say insulation adds value.
