Product Description: Roofing Membranes

We can offer urethane systems from high-elasticity for flexible applications through to harder urethanes which are suitable as trafficable membranes.

Roofing Membranes

NZ Application Service offers a variety of coatings suitable for roofing membranes, including Polyureas and urethanes as well as many hybrid products. We also offer the capability of encapsulating asbestos roofs in a membrane to contain asbestos.

Foam Composite Roofing

We have also successfully constructed Polyurethane foam roofs complete with a hard shell membrane on top. The foam is sprayed onto the roof and then sculpted to specification to achieve a fall to the drains. A Polyurea membrane is then applied over the foam to achieve watertightness and mechanical protection. This system is commonly used overseas and is now being introduced to NZ. The system is an ideal way of achieving insulation and watertightness without interfering with the internal structure of the roof. It also eliminates condensation issues on the underside metal structure of the roof.

Do you offer services for encapsulating asbestos roofs?

Yes, we offer the capability to encapsulate asbestos roofs within a membrane to contain the asbestos.

What is Foam Composite Roofing?

Foam Composite Roofing involves constructing a roof using Polyurethane foam, which is sprayed onto the roof and sculpted to achieve a fall to the drains. A hard shell Polyurea membrane is then applied over the foam for watertightness and mechanical protection.

Is Foam Composite Roofing a new system in NZ?

Yes, while commonly used overseas, Foam Composite Roofing is now being introduced to New Zealand. It provides insulation and watertightness without affecting the internal structure of the roof and also eliminates condensation issues on the underside of the metal structure.

What are the benefits of Foam Composite Roofing?

This system offers several benefits, including:

  • Insulation and watertightness without interfering with the roof’s internal structure.
  • Elimination of condensation issues on the underside metal structure of the roof.
  • Customization to achieve specific drainage fall through sculpting the foam.
