Description:

EXPOL R3.1 Black Underfloor Insulation is the highest-performing underfloor insulation option in the EXPOL range, designed for new homes requiring exceptional thermal performance. Manufactured from graphite-infused black expanded polystyrene (EPS), these rigid insulation panels help minimise heat loss through suspended timber floors, creating warmer, drier, and healthier living environments. Engineered specifically for New Zealand conditions, R3.1 panels are ideal for colder regions, exposed sites, and windy environments where superior energy efficiency is required.

Designed to meet and exceed current H1 Building Code requirements, EXPOL R3.1 delivers up to 24% greater thermal performance than R2.5 insulation, helping reduce heating costs and improve year-round comfort.
