Novatherm Warm Roof System

Novatherm Warm Roof System

The Equus SOPREMA Novatherm Warm Roof System is a light-weight, thermally insulated roofing system which consists of the Novaglass Polibit two-layer APP-modified membrane system applied over a rigid thermal PIR insulation board and vapour barrier. This guarantees a continuous and efficient thermal resistance (R-value) as per the New Zealand Building Code and is designed for use on exposed architectural flat roofs, podium decks, balconies, and terraces. It offers a cost effective, superior, thermal waterproofing system.

Novatherm Warm Roofs provide a hard, stable, UV-resistant APP-modified bituminous two-layer membrane system, finished with pressed coloured natural slates available in two colours. The roofing system is suitable for both new builds, and roof refurbishments.

The system has been assessed and complies with the New Zealand Building Code, and the Novaglass membrane system holds a current BRANZ appraisal and is also part of the Equus SOPREMA Warm Roof BRANZ Appraisal.

The basesheet is mechanically fastened and the cap sheet is torch-applied.

This system can be used on different substrates such as plywood, concrete, metal, mineral wool insulation and PIR insulation.

Why Use Novatherm?

* Good price/quality membrane.

* UV resistant APP-modified membrane available in grey or black colour.

* Good durability and easy maintenance, with a life expectancy of 20 years in thel New Zealand climate.

* Each project is independently designed with the use of project specific Condensation Risk Analysis (CRA) and Wind Uplift Studies to ensure the best system available for the buildings requirements.

* Condensation Risk Control – The roofing system moves dew point to the outside of the structure, ensuring there is no condensation build up in the ceiling cavity. No condensation means a healthier building.

* Due to the fact that there is no condensation build up from the interface of cold and warm air within the roof space, then this negates the need for additional ventilation = less penetrations through the waterproofing membrane.

* Energy Cost savings are maximized with less need for heating or cooling throughout the building. The system pays for itself over time.

* Creates more space within the ceiling for services.

* Light-weight system, strong and flexible for resistance to seismic movement.
