Allco ALLTHERM Warm Roof

Features

Designed in New Zealand for New Zealand conditions with a focus on locally manufactured and supplied products, ALLTHERM Warm Roof provides high-quality waterproofing, durability and thermal insulation.

Key Features

Ease of installation
The simplified construction of ALLTHERM uses a single sprayable low VOC contact adhesive to adhere all of the elements of the system reducing time and labour costs.

PIR Insulation Boards
Excellent thermal performance, offering 30mm to 150mm thick insulation panels to suit your project requirements.

Built in Leak Detection System
Allco ALLTHERM Warm Roof is installed with foil faced PIR boards, connected with conductive foil tape to create a continuous conductive medium. This system is called EFVM (Electric Field Vector Mapping) and allows membrane leaks to be detected using an electric current. Even in the case of minimal contact with moisture, the system closes the electrical circuit. Moisture penetration can be located quickly and cost-effectively repaired.

Vapour control
The system consists of a reinforced Vapour Barrier membrane that is self-adhered to an approved substrate – concrete, timber or longrun steel – approved by Allco Waterproofing Solutions Ltd.

BRANZ Appraisal
ALLTHERM Warm Roof is BRANZ Appraised (1166 – 2021) including Allco JM our Allco Casali RMBM. Both membrane types are individually BRANZ appraised systems and will provide a watertight and aesthetically pleasing surface for your new roof.

Warranty
Allco provides a 20 year product warranty against material defects for the ALLTHERM Warm Roof and Deck system. The warranty must be applied upon completion of the project by the Allco Approved Applicator. The workmanship will be covered separately by the Allco Approved Applicator.
