Membrane high-performance roof system

Ultratherm Xtreme

Insulated membrane roof assembly providing thermal, acoustic and structural performance for high-end buildings and low-pitch applications.

System overview

Membrane roof system

Insulated membrane roof assembly providing thermal, acoustic and structural performance to meet the precise project requirements. Install the Ultratherm Xtreme system over RoofLogic's engineered structural base deck or standard plywood and concrete substrates.

Engineers have meticulously designed each component to deliver the utmost levels of performance. RL BaseDeck is the only steel base deck that has undergone rigorous testing in New Zealand and Australia for wind uplift, point load, and fastener pull-out resistance. RL PIR Board provides exceptional thermal performance and improved impact resistance, with compressive strength twice that of most other PIR products on the market.

Ultratherm Xtreme is a commercial membrane roofing solution providing superior thermal and acoustic performance and extreme durability with Fibertite KEE membrane and Derbigum modified bitumen membrane. For non high-performance roof system applications, the membranes can be adhered to a range of substrates including concrete or ply.

Where Ultratherm Xtreme excels

High-end buildings

Superior thermal and acoustic performance for premium commercial and institutional buildings demanding the highest quality roof system.

Low pitch roofs

Membrane system ideal for low-pitch roof applications where metal skin systems are not suitable.

Trafficable roofs

Fibertite KEE membrane provides trafficability for roofs requiring maintenance access or rooftop plant equipment.

Key components

Engineered components

RL BaseDeck

The only steel base deck rigorously tested in New Zealand and Australia for wind uplift, point load, and fastener pull-out resistance.

RL PIR Board

Exceptional thermal performance with improved impact resistance — compressive strength twice that of most other PIR products on the market.

Fibertite KEE & Derbigum

Fibertite KEE membrane and Derbigum modified bitumen membrane provide extreme durability and weathertightness for long-term performance.

Recover system available

Ultratherm Xtreme Recover

The Ultratherm Xtreme Recover System is a membrane system constructed over existing substrates for upgraded weathertightness and extended durability.

Unlike typical re-roofing projects, the system allows the building's occupants and activities to remain undisturbed; no relocation is required. Tapered boards enable creation of pitches to guide and redirect the flow of water on flat roofs.
