Nuralite: Roofing the Holiday Inn Express and Suites Queenstown

Designed to incorporate abstract elements that mirror the nearby mountain ranges and the glacier that once occupied the Wakatipu valley, the Holiday Inn Express and Suites Queenstown was the first of the franchise to open in New Zealand.

This unique addition to downtown Queenstown was strategically planned to transform a residential city block. The building was created to seamlessly integrate into the surrounding area, with an emphasis on a blend of natural and man-made materials. The exterior look was bold with the cladding and roof shape being key design features.

With the unique array of roofs at different pitches, the Holiday Inn project utilised Nuraply 3PM double-layer and Nuraply TPO single ply on the membrane sections. The Nuratherm Warm Roof system was also specified to deliver high performance insulation and acoustic values. The CodeMark certified system enabled a roof fall of one degree, which is perfect for areas with specific height restrictions.

The project featured Nuraply 3PT and Nuraply 3PG in a tanking application. This helped ensure the structure remains watertight and prevents water ingress from underneath.

The Holiday Inn Express and Suites is an impressive project that demonstrates how modern design can coexist with the natural environment.

Adding to the beauty of downtown Queenstown, the project was selected as a finalist in the World Architecture Festival 2021 and was the 2022 Southern Architecture Award Winner for Planning + Urban Design.

Nuratherm Warm Roof System

Nuralite

View Product

The Nuratherm system puts the insulation where it should be, above the substrate, to completely enclose the roof area with a highly efficient insulation blanket.

The Nuraply Nuratherm System has been appraised by BRANZ for use as an insulating roof on buildings within the following scope:

the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with regards to building height and maximum floor plan areas; and,
on limited access flat roofs with concrete, timber or steel structural decks subject to specific structural design; and,
with roofs constructed to drain water to gutters and drainage outlets complying with the NZBC; and,
with roofs constructed to suitable falls (Refer Paragraph 15.3 and 15.4); and,
with no integral roof gardens; and,
situated in NZ3 3604 Wind Zones, up to, and including 'Extra High'.

The Nuraply Nuratherm System has also been appraised for durability and thermal performance as an insulated roofing system on buildings that are the subject of specific design with no building height restriction. Building designers are responsible for the building design and for the incorporation of the Nuraply Nuratherm System into their design in accordance with the declared properties and instructions of Nuralite Waterproofing Ltd.

In the opinion of BRANZ , the Nuraply Nuratherm System, if designed, and used, installed and maintained in accordance with with the statements and conditions of Appraisal No.732 (2012), will meet the following provisions of the NZBC:

Clause B2 Durability: Performance B2.3.1(b), 15 years. Nuraply Nuratherm System meet this requirement
Clause E2 External Moisture: Performance E2.3.1 and 2.3.2. Nuraply Nuratherm System meet these requirements
Clause F2 Hazardous Building Materials: Performance F2.3.1. Nuraply Nuratherm System meet this requirement and will not present a hazard to people
Clause H1 Energy Efficiency: Performance H1.3.1(a). The Nuraply Nuratherm System will contribute to meeting this requirement

Nuraply Nuratherm System is appraised as an Alternative Solution in terms of New Zealand Building Code compliance.

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.

Nuraply 3PT/3PTM

Nuralite

View Product

Nuraply 3PT Tanking System is a positive waterproofing system that is watertight immediately upon installation.

Nuraply 3PT(M)systems have been developed for positive long-term, low maintenance waterproofing of construction features such as:

Foundations
Basements
Lift Shafts and pits
Underslab

Nuraply 3PT(M) provides a robust watertight solution for areas where water is likely. The system can tolerate some hydrostatic pressure but specific design is required for areas of high hydrostatic pressure such as large building sites by the sea.

Based on expert opinion, verified by Auckland Council, Nuraply 3PT and 3PTM will meet the following provisions of the NZBC:

Clause B2 Durability: Performance B2.3.1(a), not less than 50 years performance expectancy.
Clause E2 External Moisture: Performance E2.3.3, roofs and walls shall prevent the penetration of water.
Clause F2 Hazardous Building Materials: Performance F2.3.1. Does not pose a hazard to humans.
