Nuraply Everguard TPO Membrane Declared Red List Free

To align their product offerings with their views on sustainability, Nuralite has sought to become Declare verified Red List Free, in accordance with the International Living Future Institute. Declare is a reliable and independent declaration label that discloses Red List status and potential environmental impact. The Red List is frequently updated and contains hundreds of damaging chemicals and toxins. The Nuraply Everguard TPO roof membrane and warm roof system is the first Nuralite system to be Declared and help Nuralite toward achieving their goal.

The Adhered TPO Roofing system is Declared Red List Free, meaning that the product ingredients are 100% disclosed to 100ppm and do not contain any Red List chemicals. Consisting of a Nuraply Everguard TPO and Polyiso Insulation board, the TPO Warm Roof provides energy efficiency and is 100% recyclable, being made from products that are non-hazardous to the environment. At the end of its life the mechanically adhered system can also be de-constructed.

This makes the Nuraply Everguard TPO an excellent candidate for small and large commercial projects with an emphasis on environmental rating, specifically the Living Building Challenge which is widely considered as the most advanced green building standard in the world. The TPO Roofing System has been shown to meet both the Materials Petal and the Emissions Testing criteria for the Living Building Challenge.

Nuraply Everguard TPO is offered in Light Grey and White, and with the Polyiso insulated roof option. This will reflect solar radiant heat and insulate from the cold, both properties offering substantial cost saving advantages in terms of heating/cooling.

In addition to the cost-saving traits of TPO, flexibility and durability make this product resistant to tears and other impact damages. After construction, it is common for buildings to settle and move. The flexibility of the TPO membrane allows the material to perform under these variable conditions without compromising the integrity of the membrane.

The demand for building materials that support human and environmental health is a trend that we will see increasing. By having their Adhered TPO Roofing system Declared as Red List Free Nuralite hopes it will inspire others to move forward in helping them achieve complete product transparency.

Declared

Nuraply TPO Roof and Deck Membrane Systems are for use as roof and deck waterproofing membranes on buildings within the following scope:

the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; or,
the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with respect to building height and maximum floor plan area when subject to specific structural design; and,
with building structures designed and constructed to meet the requirements of the NZBC; and,
with substrates of plywood or suspended concrete slabs; and,
with minimum falls for roofs of 1:30 and decks of 1:40
with decks that have a maximum area of 40 m2; and,
situated in NZS 3604 Wind Zones, up to, and including Extra High

Nuraply TPO Roof and Deck Membrane Systems are also for use as roof and deck waterproofing membranes on buildings within the following scope:

subject to specific structural and weathertightness design; and,
with substrates of plywood or suspended concrete slab; and,
situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 3 kPa; and,
with the weather-tightness design of all junctions for each specific structure being the responsibility of the building designer.

Roofs and decks waterproofed with Nuraply TPO Roof and Deck Membrane Systems must be designed and constructed in accordance with the following limitations:

nominally flat roofs and decks and pitched roofs constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
with no integral roof gardens; and,
no steps in level within the deck area, no integral roof gardens and no downpipes direct discharge to decks; and,
with deck membranes continually protected from physical damage by a pedestrian protection system. The design and construction of the substrate and movement and control joints is specific to each building, and therefore is the responsibility of the building designer and building contractor.

In the opinion of BRANZ, Nuraply TPO Roof and Deck Membranes, if designed, used, installed and maintained in accordance with the statements and conditions of this Appraisal, will meet the following provisions of the NZBC:

Clause B2 Durability: Performance B2.3.1 (b) 15 years, Nuraply TPO Roof and Deck Membranes meet this requirement.
Clause E2 External Moisture: Performance E2.3.1, E2.3.2 and E2.3.6. Roofs incorparating Nuraply TPO Roof and Deck Membranes meet these requirements.
Clause F2 Hazardous Building Materials: Performance F2.3.1. Nuraply TPO Roof and Deck Membranes meet this requirement and will not present a health hazard to people.
