Overview

The RoofLogic FiberthermX system is a proven and exceptional commercial roofing solution that offers a multitude of benefits in terms of design, performance, and construction.

Distinguishing itself from traditional metal roof assemblies, the RoofLogic FiberthermX system excels in providing superior thermal performance and effectively mitigating condensation risk.

At the core of the FiberthermX system lies the structural rail assembly, strategically employed to separate the outer skin from the internal liner deck. By incorporating the structural rail assembly, the FiberthermX system optimises the utilisation of low-density Glass Wool insulation, eliminating thermal breaks and cold bridging that are common flaws in conventional roof assemblies.

overview

Engineers have meticulously designed each component of the RoofLogic Ultratherm Xtreme system to deliver the utmost levels of performance.

RL BaseDeck is the only steel base deck that has undergone rigorous testing in New Zealand for wind uplift, point load, and fastener pull-out resistance.

RL PIR Board provides exceptional thermal performance (and meets all the Climate Zones for H1 as per the NZBC).  It also offers improved impact resistance due to a high compressive strength twice that of most other PIR product in the New Zealand market.

When your project requires enhanced impact resistance/trafficability and acoustics, RoofLogic specifies a range of high-density roof boards to meet its demands.

RoofLogic Ultratherm Xtreme is a commercial membrane roofing solution that provides superior thermal and acoustic performance and extreme durability with the use of our Fibertite KEE membrane and Derbigum modified bitumen membrane.

recover

Suitable applications: Existing membrane and metal skin roofs on occupied buildings.

FiberthermX, Ultratherm Xtreme and Ultratherm MSR are available as Recover Systems. RoofLogic provides a suite of re-roofing solutions that allows the refreshing of existing roof assemblies. RoofLogic designs and engineers Recover systems to provide long-term durability, weathertightness, and enhanced thermal and acoustic performance. The simplification of the re-roofing process with a fully warranted system solution has made Recover our most popular system.

Design Flexibility

RoofLogic Recover systems offer complete flexibility. RoofLogic have been involved in numerous projects where the Recover Systems have provided a simple, cost-effective, long-term solution where a traditional re-roof option would have been problematic. See below some examples of Ultratherm Xtreme Recover assemblies that have been installed throughout New Zealand.

Existing trough section roofing

Install the RoofLogic Recover system over existing metal trough section roofing. This roofing material was traditionally installed at low pitch. Low pitch, damage, poor detailing, complex junctions all contribute to these roofs being compromised in respect to weather-tightness. Often these roofs are the perfect candidate for a Recover solution. RoofLogic will examine the existing roof and develop a structural scheme that allows for a robust, warrantable Recover system to be installed.

Existing Concrete Substrates

The RoofLogic Recover system can be installed over existing concrete substrates. The benefit of the Recover system is that existing membranes can be left insitu and can often be re-purposed as the vapour control layer where the Recover includes a new insulation layer.

In our most basic concrete overlay RL Roof Board HD is installed over the existing membrane and mechanically attached to substrate. The board fixing pattern is designed by RoofLogic’s engineer and takes account of the project wind loads – this effectively takes the adhesive bond of the existing membrane to substrate out of the equation and provides certainty in respect to structural performance of the system.

Existing Timber Substrates

The RoofLogic Recover system can be installed over existing timber substrates. The benefit of the Recover system is that existing membranes can be left insitu and can often be re-purposed as the vapour control layer where the Recover includes a new insulation layer.
