We offer a range of high-performance insulation solutions, including phenolic foam boards, pre-formed phenolic pipe insulation, and custom-fabricated thermal cladding components.

All products are engineered for superior thermal resistance, fire safety, and moisture control.

Polyphen® is our proprietary facing material used on selected insulation products.

It enhances strength, fire resistance, and water protection when bonded to the phenolic foam core, making it ideal for demanding environments like HVAC systems or external cladding applications.

Our insulation systems are commonly specified for commercial and industrial buildings, HVAC infrastructure, mechanical pipework, and high-spec environments requiring Group 1 fire performance and thermal efficiency.

Our phenolic-based insulation solutions, including FourPLUS XFP and Polyphen®-faced boards, achieve Group 1 fire ratings and comply with AS/NZS 1530.3 and ISO 5660 standards, making them suitable for use in high-safety zones such as risers, plant rooms, and return air plenums.

Yes. Our phenolic insulation products are tested to meet or exceed requirements under the New Zealand Building Code (NZBC) as well as relevant ISO and AS/NZS standards for fire, thermal, and durability performance.

Depending on the thickness, our phenolic boards typically offer R-values from R1.8 (at 25 mm) to R5.0 (at 75 mm), delivering superior insulation performance in minimal space compared to other materials.

Yes, when protected and sealed correctly. Boards faced with Polyphen® are water-resistant and robust enough for ventilated façades, parapet insulations, or areas requiring weather protection.

Yes. Our pre-formed phenolic pipe insulation is specifically designed for HVAC and mechanical service pipework carrying both hot water (up to 120°C) and chilled water (down to 0°C).

It suits copper, steel, and plastic piping, and minimizes heat loss or condensation risk.

Yes. We manufacture custom-cut, pre-formed, and laminated insulation parts tailored to your specific dimensions. These include bends, T-sections, valve boxes, and insulated wraps for non-standard configurations.

Yes. Our phenolic insulation boards and shapes can be integrated with systems like Decrashape XFP to provide both thermal protection and decorative plastered finishes, ideal for façades and architectural mouldings.

Yes. Installation manuals, product data sheets, and compliance documentation are available upon request to ensure correct application, fixing, and sealing of our insulation products.

Standard sizes and stock items usually dispatch within 1–5 working days. Custom-fabricated components may require longer depending on complexity and volume.

Yes. We offer nationwide delivery and export options. All shipments are professionally packed to protect against damage during transport.

Yes. Accumen Shapes supplies insulation products to both domestic and international customers.

All shipments are securely packaged for international freight, and we can assist with documentation and compliance requirements upon request.

Decorative mouldings may be water repellent in themselves, but due to the diverse situations they may be used in, they are not to be used as a weather tight material. Architects and competent tradespersons must follow professional trade specifications for the application of a weather tight membrane on the building before fixing Accumen Shapes Ltd decorative products. We strongly recommend that informed and competent tradespersons fix the mouldings and shapes.

Installation methods should be clearly understood BEFORE installing decorative products manufactured by Accumen Shapes Ltd.

Construction using Accumen Shapes Ltd products must be in accordance with good building practice, in accordance with the New Zealand Building Code and all statutory and relevant New Zealand standards.
