How it works

The Role of a Vapour Barrier

The Challenge
In an insulated roof system, the interior surface of the insulation closely matches the internal air temperature, preventing moisture in the air from condensing. However, as warm air moves beyond this surface and through the insulation, it encounters cooler surfaces, leading to condensation. This accumulation of condensation diminishes insulation effectiveness and can result in long-term durability issues for the roof materials.

Dimond Advanced Standard as a solution
Dimond Advanced Standard offers an effective solution to the challenge of condensation in insulated roof systems by incorporating a vapour impermeable layer, which prevents warm air migration and reduces the risk of condensation accumulation.

This comprehensive approach ensures that moisture from warm air does not reach cooler surfaces within the roof structure, thus enhancing the durability and performance of the system over the long term. Additionally, tailored Dimond Post and Rail heights cater to different Climate Zones in New Zealand, meeting energy efficiency requirements while addressing specific environmental challenges. With streamlined construction timelines, supported by early close-in and Liner Deck installation, Dimond Standard provides efficiency and safety benefits.

Aligned with Building Code and NZ Metal Roofing Code of Practice standards, it assures weather-tightness and reliability, boasting a proven track record of over 60 years in the commercial roofing sector. Overall, Dimond Standard delivers thermal and acoustic performance, effective condensation management, and efficient construction programs.
