We offer 100% Polyester and Glasswool Underfloor Insulation

Premier 100% Polyester Insulation is proudly manufactured in New Zealand and our Glasswool Insulation is imported from our long-standing partners in Taiwan. Both insulation options are two of the most commonly found in New Zealand homes. 

Living in a home that’s constantly chilly or feels damp is far from ideal. Without adequate insulation, heating or cooling your home becomes inefficient, as precious energy simply leaks out through walls, ceilings, and floors without any barrier to stop it. This not only drains energy but also your money.

Why should you insulate your underfloor? 

While newer homes are often built on concrete slabs, older homes built on piles or wooden frames can lose up to 12-14% of their heat through uninsulated floors. Underfloor insulation is a cost effective way that acts as a barrier, preventing drafts and cold air from seeping in, especially during winter. 

Premier 100% Polyester Insulation is the recommended option for underfloor installation due to it being moisture and vermin resistant and how it’s designed to easily fit between floor joists for a tight install, maximising efficiency. 

The Premier Choice: 100% Polyester Insulation

Tailored for New Zealand structures, our 100% Polyester Insulation stands out from the crowd. Here’s why:

  • Safety First: Unlike some other insulation types, our Polyester Insulation is non-irritating, mitigating risks associated with respiratory or skin allergies. This ensures a safer environment for both installers and residents.

  • Moisture-Resilient: Underfloor spaces are notorious for dampness. Our insulation combats this, maintaining its shape and thermal attributes even in humid settings. Its moisture resistance also wards off mold, promoting a healthier space. 

  • Electrical Safety Assured: No more fretting about intricate electrical systems. Our insulation won’t interfere with the wiring, solidifying its reputation as a safe choice for homes with extensive electrical networks below the floor.

  • Flexible and Comprehensive: The adaptability of polyester insulation guarantees a snug fit between joists, irrespective of any uneven spacing. This ensures a thorough coverage, eliminating potential heat-escape gaps.

Understanding Insulation and R-Values? 

Insulation’s capacity is marked by its R-Value; higher values mean more warmth. With the recent shift in the NZ Building Code, underfloor insulation will see a rise in R-values depending on their climate zone, from R1.5 to up to R1.7 for slab-on-ground homes and R2.5 to R3.0 for homes with timber sub-floors.

Additionally, our team is well-versed with the Healthy Homes Insulation Standards, ensuring that your home not only meets but exceeds the required norms.

Key Considerations for Underfloor Insulation: 

  • Existing Insulation: Before installing underfloor heating, assess the current insulation level of the room. A well-insulated space requires less energy to heat, leading to cost savings.
  • Room Characteristics: Rooms with multiple windows or high ceilings might need a higher heating output. Ensure your insulation is tailored to these requirements.
  • Floor Construction: Whether you have a concrete base, timber joists, or an upstairs floor, the type of floor construction will influence your insulation choices.
