Additional Information
Warmafloor provides excellent thermal performance due to a low thermal conductivity and a complete and consistent installation. Warmafloor provides a choice of R-Values based on the installed thickness and installed weight per square metre. The stated thermal resistance (R-Value) is provided by installing the required density at the thickness (per the manufacturer’s instructions).
Warmafloor is designed to be installed at a target density of 8-9kg/m3. For further information, refer to the thermal performance table for more details.. Warmafloor will achieve R-Values that with the use of NZS 4214 are able to meet the minimum requirements of NZS 4218 and the Energy Efficiency requirements for floors and midfloors.
Improves sound transmission class (STC) by between 4 and 10 points.
Reduces energy usage and utility bills for heating and air conditioning.
Carbon negative. When used as thermal insulation, Warmafloor will recover the energy used to produce it within days of installation and it will continue to reduce carbon generation for as long as it is in place.
Warmafloor is an engineered solution which incorporates a system approach to the insulation of your ceiling space. A range of accessories are supplied with the System to provide a range of solutions and performance checks. Backed by the Approved Installer network, to provide confidence in the performance of the product.
– Fast and easy install with an Approved Installer.
– A wind wash barrier is installed first. It supports Warmafloor and provides enhanced wind and weather protection, resulting in less drafts and higher installed performance.
– Warmafloor insulation is then blown into the cavity at the desired density.
– Non-combustible, non-corrosive.
– Will not rot, mildew or deteriorate.
– Will not sustain vermin.
– Will not settle.
– Consistent, reliable performance.
– Performs for the lifetime of the building.
To achieve the required R-Value, this product must be installed using an approved blowing machine and equipment. Installation must be complete inline with the system guidelines and by an Approved Installer.
