Thermal Break

Maintaining the thermal resistance of a wall assembly in buildings is a requirement needed to meet Clause H1 of the New Zealand Building Code. A thermal break is essential to prevent ‘thermal bridges’ between the external cladding and the steel framing.

There are quite a few options available in the market from Polystyrene sheets and strips to ventilated plastic cavity battens to rigid air barriers. They all offer a thermal break solution and depending the specific requirements of your project some may work better than others. One product that ticks a lot of boxes is IBS RigidRAP-XT.

IBS RigidRAP-XT is a cutting-edge product designed to enhance the durability and efficiency of your building projects.
IBS RigidRAP-XT is an 8mm OSB board laminated with a certified building paper and a 10mm lightweight graphite EPS on the inside. This triple-layer rigid air barrier system provides dual protection from the weather during construction and acts as a thermal break, making it ideal for both steel and timber frame buildings.
As the industry moves to a real focus on sustainability IBS RigidRAP ticks all the boxes as we focus on ensuring sustainability and durability in all our products.
Some Key benefits include
• Exceptional Thermal Performance: RigidRAP-XT significantly reduces heat loss, helping to maintain a comfortable indoor temperature and lower energy bills.
• Bracing Element: Use IBS RigidRAP-XT as your bracing element for your next project and save time and money by reducing the need for further bracing inside your building.
• Moisture Resistance: The product’s moisture-resistant properties prevent water infiltration, protecting your building from potential damage and mould growth.
• Rigid Air Barrier: As a rigid air barrier, RigidRAP-XT reduces unwanted air leakage, enhancing the energy efficiency of your building and improving indoor air quality.
• Durability: Made from high-quality materials, RigidRAP-XT is built to last, offering long-term protection and performance.
• Easy Installation: RigidRAP-XT is lightweight and easy to handle, making the installation process quick and efficient, saving you time and labour costs.
• Versatility: Suitable for a wide range of applications, RigidRAP-XT can be used in residential, commercial, and industrial projects.
• Reduced building time: Its lightweight and easy-to-install nature speeds up the construction process. After installation work inside and outside at the same time
• Enhanced site security: The rigid structure provides greater security on the construction site.
• Thermal break: The 10mm foam layer provides an R-Value of 0.41, improving the energy efficiency of your building
• Added Thermal Resistance: With an R-Value of 0.41 IBS RigidRAP-XT provides excellent thermal insulation, enhancing energy efficiency in building designs.
IBS RigidRAP-XT is CodeMark certified and meets all requirements of the New Zealand Building Code. It can be exposed to the weather for up to 90 days, making it a reliable choice for any construction project.
