ICF-Therm is an Insulating Concrete Formwork (ICF) system that allows for fast construction of creative, flexible buildings with low running costs and a long sustainable life.
Where can it be used?
Benefits of ICF
Building Regulations & Nzeb - We understand that compliance with Building Regulations and the recently imposed obligations of NZEB is crucial for you. Our ICF walls work in conjunction with complementary best-practice energy-efficient options that help you easily achieve compliance alongside NZEB requirements and A Ratings.
How high can ICF Therm be built - ICF-Therm blocks are designed to withstand the pressures of wet concrete with pours up to 3 meters in height.
Thermal Bridging - With an ICF-Therm wall, the thermal mass of the concrete combined with the expanded polystyrene insulation inside and outside the concrete core help keep the building warm in winter and cool in summer, conserving energy and reducing temperature fluctuations.
Air Tightness - ICF-Therm walls eliminate air leakage due to the sealing effect of concrete and the low permeability of the formwork maintaining a strong air barrier over the long life of a building, increasing energy efficiency and allowing controlled ventilation.
Fire Resistance - By providing a two-hour fire rating our products are fire-resistant to very high standards.
NSAI Certified - Our system is certified by NSAI.
