Redefining natural ventilation with intelligent engineering, contemporary aesthetics, and architectural innovation.
Bringing Australian Innovation to Malaysian Architecture
At Trend Thermal Windows & Doors Sdn Bhd, we believe that exceptional architectural solutions should seamlessly combine aesthetics, functionality, and engineering excellence.
We are proud to announce our appointment as an Official Dealer of Doric Paraflow Dual-Blade Glass Louvres in Peninsular Malaysia, introducing an innovative Australian window technology to architects, designers, developers, and homeowners seeking a new approach to natural ventilation.
Developed by Australia’s renowned architectural hardware specialist Doric, the Paraflow system challenges conventional glass louvre design with its distinctive dual-blade configuration, offering a sophisticated combination of controlled airflow, natural daylight, and modern architectural aesthetics.
A fresh perspective on ventilation begins here.
Double the Blades. A Smarter Approach to Ventilation.
What makes Doric Paraflow different from conventional glass louvres?
The innovation lies in its unique dual-blade glass configuration, featuring two precisely offset glass blades within each louvre clip.
When closed, this intelligent arrangement creates an air cavity between the inner and outer glass blades, introducing an additional insulating layer to the window assembly.
When opened, the system allows adjustable natural airflow, helping create brighter, more comfortable, and naturally ventilated indoor environments.
Designed with both functionality and architectural flexibility in mind, Paraflow offers:
- Innovative Dual-Blade Technology – A distinctive two-layer glass arrangement that differentiates Paraflow from conventional single-blade louvre systems.
- Enhanced Thermal Design – An air cavity between the closed glass blades provides an insulating buffer.
- Natural Ventilation & Daylight – Adjustable glass blades allow fresh air and daylight to enter the living environment.
- Manual & Motorised Options – Flexible operating solutions to accommodate different architectural applications.
- Contemporary Architectural Aesthetics – A refined glass louvre solution suited to modern residential and architectural designs.
Whether incorporated into a luxury residence, contemporary bungalow, or custom-designed architectural façade, Paraflow opens new possibilities for integrating natural ventilation into sophisticated window designs.
Engineered with Performance in Mind
Beyond its distinctive appearance, Doric Paraflow has undergone independent performance testing to evaluate key characteristics of the system.
Based on the manufacturer’s available technical reports, tested specimens have demonstrated the following results:
Water Penetration Resistance – 600 Pa
The specimen tested by Azuma achieved a water-penetration resistance rating of 600 Pa, demonstrating resistance to water ingress under the specified test conditions.
Ultimate Wind Pressure – ±8,000 Pa
The Azuma specimen withstood positive and negative ultimate test pressures of 8,000 Pa, highlighting its structural performance under the tested conditions.
Acoustic Performance – Rw 30
In separate testing conducted by CSIRO, the tested glass louvre specimen achieved a weighted sound reduction index of Rw 30 with its blades fully closed.
Technical clarification: These figures represent results from separate tested specimens and should not be interpreted as universal or combined performance ratings for all Paraflow configurations. The Azuma report also records an air-infiltration classification failure. Actual performance and project suitability depend on the glass specification, window dimensions, frame assembly, installation details, and relevant performance requirements.
For architectural consultants and project teams, the supporting test reports are available below for further technical evaluation.
