Technical Statement
Product Description
The Thermosash PW1000 is a structurally glazed unitised curtainwall suite designed for high-rise or low-rise applications where the projecthas large spans or large panes of glass requiring higher strength or specific design systems. The advantage of this system is, that whilst itutilises a mullion and transom system internally to hold the glass or other elements, the surface is generally free from any visible aluminiumstructural element - providing a smooth panel face.

NZBC Clause B1 Structure
COMPLIANCE BY B1/VM1 (project-specific design)
Compliance with B1 is shown by way of engineering calculations and/or testing, and reports are attached to the compliance pathway submission.
- Clause B2 Durability: Performance B2.3.1, B2.3.1(b), B2.3.1(c)
NZBC Clause B2 Durability
ACCEPTABLE SOLUTIONS B2/AS1There are no Acceptable Solutions available for aluminium and steel, and protection is provided through surface treatment in accordance with:• AS/NZS 2312:2014 - Guide to the protection of structural steel against atmospheric corrosion by the use• of protective coatings.• AAMA 2605-05 - Voluntary specification, performance requirements and test procedures for superior performing organic coatings on aluminium extrusions and panels.• AS 37155:2002 - Metal finishing thermoset powder coatings for architectural applications of aluminium and aluminium alloys.• AS 1231:2000 - Aluminium and aluminium alloys - anodic oxidation coatings.• WANZ - Specification for powder coatings on architectural aluminium products.• SNZ TS 3404:2018 - Durability requirements for steel structures and components
COMPLIANCE BY B2/VM1
All elements of the Thermosash product/system are specified by Thermosash to (with only normal maintenance) satisfy the performance requirements of the Building Code for 5 years (Surface Finish), 15 years(System), 50 years (Fixings/Connections) as appropriate.Generally, all elements are designed from aluminium. Where engineering requirements demand stronger materials stainless steel (304 or 316 as appropriate), or steel (coated to SNZ TS 3404:2018) will be used.

Thermosash Group owns and operates the largest facade testing facility in New Zealand (WEC) where we test our systems and custom-designed suites to ensure compliance with the codes or project-specific requirements.
All the Thermosash suites are independently laboratory tested to IANZ(International Accreditation New Zealand).
Supporting evidence
The product has and can make available the following additional evidence to support the above statements:
Product Criteria
Design requirements
Integrated Elements
Almost an unlimited type of materials can be integrated into a unitised panel, including different glass types, metals, brackets to receive externally mounted fins, louvres, venetians or building signage for example.
Thermosash Services
Thermosash can provide further technical support, design and performance data on request. We are able to provide a full design and costing service covering the many technical and performance aspects associated with a particular building design. We can design, fabricate, install and glaze our systems anywhere in New Zealand or overseas either in conjunction with our local specialists or directly through our own organisation.
Installation requirements
Prefabrication
Panel wall systems are manufactured and glazed in a factory environment, stored and only transported to site when needed.
These pre-fabricated and glazed panels are delivered to the floors in crates and positioned by floor mounted cranes or monorail units. The panels have interlocking legs, requiring sequential placement around the building floor before the next level can be installed.
It is highly recommended that the units are installed from ground up in predetermined directional order to maintain the best detail connection between panels. Special methodologies need to be considered when recladding a building demands a top down approach.
Maintenance requirements
Looking After Your Building
Maintaining glass, metals and stone are all particular to the environment that they are placed in: eg. marine, environmental pollution, exposure to natural washing, etc.
It is recommended by almost all material suppliers that building washing should occur every 3-6 months to prevent staining to glass and prevent environmental pollutants from corroding metals and to maintain the material warranties.
A full maintenance manual is provided on completion of a project for all the elements integrated within a project.
Warrantees
The standard warranty is 10 years from the date of practical completion for these products. This covers workmanship and weather tightness,providing the subcontract includes fabrication, installation and glazing of all components.
• Structural integrity (framing, brackets, fixings) - 50 years
• Material and components life to first maintenance - 10 years
• Surface finish / seals / hardware - 5 years
