Dimond Advanced Non-Vented

Thermal Performance:

• Utilizes PIR board core with customizable R-values (R2.0 to R7.0), ensuring tailored efficiency.

Condensation Management:

• Features a complete vapour barrier layer, separating internal and external environments to eliminate condensation concerns.
• Includes a two-part water vapour and condensation control system with vapour barrier and underlay.

Construction Timelines:

• Streamlines construction timelines with early close-in capability using Liner Deck and a self-adhesive vapour control layer.

Flexibility:

• Offers design flexibility with various options from the Dimond Range, allowing customization based on base metal, coating, and exposure zone.

Other Features:

• Suitable for all environments and cost-effective compared to the vented system.
• Has limitations on sheet length (up to 25m) due to thermal movement.
• Overcomes composite insulated roof panel limitations.

Limitations:

• Not intended for installation over a plywood liner.
• Roof pitch meets the minimum required pitch for the selected top sheet product.

The Non-Vented Difference

Identifying the difference between Non-Vented and Vented.
We recommend the vented roof rail on roof sheets over 25m and in freezing climates as the vented rail allows the top sheet to expand and retract separately from the components below. Additionally, in freezing conditions, it serves as a cold deck, minimizing the chances of ice damming.

Environmental Challenges
New Zealand's inherently variable climate challenges occupant comfort in buildings, requiring effective insulation and moisture management to maintain year-round comfort and reduce energy consumption. Without the correct systems in place, the fluctuating weather conditions, ranging from hot summers to cold winters, can lead to thermal discomfort and moisture-related issues such as condensation and mould growth. Existing methods often fail to provide custom solutions for effective insulation and vapour barrier needs, resulting in inefficient thermal regulation and increased energy usage.

Addressing the Challenge with the Advanced Non-Vented Solution
Dimond Advanced Non-Vented effectively tackles the challenge of New Zealand's variable climate by providing a ground-breaking solution for thermal performance. Its customizable R-values (R2.0 to R7.0) offer tailored efficiency, ensuring optimal insulation for different climatic conditions. The product eliminates condensation concerns with a complete vapour barrier layer, effectively separating internal and external environments to prevent moisture-related issues such as condensation and mould growth.

Additionally, Dimond Non-Vented streamlines construction timelines with early close-in capability using NPM Liner Deck and a self-adhesive vapour control layer, ensuring efficient installation and minimizing construction-related disruptions. Compliant with Building Code and NZ Metal Roofing Code standards, Dimond Non-Vented assures weather-tightness, while its separable top skin allows precise customization, overcoming the limitations of composite insulated roof panels.

Furthermore, the integration of the Acoustic Board, Audioperf, effortlessly enhances acoustic performance, providing a comprehensive solution for occupant comfort in buildings across New Zealand's variable climate.
