Metro Glass Xcel™ Low E Double Glazing DGU

High thermal performance Low E double glazing units compliant for new H1 requirements

The following information has been provided by Metro Glass demonstrating how this product complies with the Building Product Information Requirements.

Product Description

Metro's high performance Xcel™ double glazing can significantly reduce heat loss, and make for a warmer, drier, healthier home. Double glazed windows will help keep generated heat inside, keeping your home at a more consistent temperature - cutting down your power costs to heat in winter.

Double glazing is made from two pieces of glass sealed together with an air space in between. A double glazed window sits in your window frame just as regular single glazing would, but provides a number of extra benefits. Whether you are looking to keep your home warmer, quieter or reduce condensation, Metro can recommend the best combination of glass types to meet your needs because they have the widest range in NZ.

• Xcel™ is the classic option, perfect for most New Zealand homes

• Up to 61%* better heat retention

• Lets in 80% of visible light, enabling warm, naturally light-filled spaces

New Zealand Building Code (NZBC)

The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:

Clause B1 Structure: Performance B1.3.1, B1.3.2, B1.3.3, B1.3.4
B1 Structure: Metroglass IGUs are manufactured to project specific requirements in accordance with acceptablesolution B1/AS1 (which cites NZS4223 set of standards)
Clause B2 Durability: Performance B2.3.1
B2 Durability: Metroglass IGUs are manufactured to Acceptable Solution B2/AS1 and are tested by IGUMA to BS EN1279–4 in accordance with NZS4223.2. Storage, handling, transport, preservation and glazing must be carried outin accordance with AS/NZS 4666:2012. Water must not be trapped against the edge seal as this will result in failureand ultimately condensation on the internal glass surfaces. IGUs must not be exposed to elevated heat.Refer to Window & Glass Association of New Zealand (WGANZ) website for proof of compliancehttps://www.wganz.org.nz/double-glazing-manufacturers/
Clause E2 External moisture: Performance E2.3.1, E2.3.2, E2.3.7
E2 External Moisture: Glass is impervious to water. Adequate drainage is required in the glazing system to ensurethat water, moisture, or condensation are not trapped against the edge seal as this will result in failure
Clause F2 Hazardous building materials: Performance F2.3.1, F2.3.2, F2.3.3, F2.3.3(a), F2.3.3(b), F2.3.3(c)
· F2 Hazardous Building Materials: Metroglass IGUs likely to be subject to human impact safety can be manufactured to specific project requirements to comply with NZS 4223.3 in accordance with F2/AS1 clause 1.0. NZS4223.3. Metroglass IGUs can be manufactured in accordance with NZS4223.3 for human impact location to the project requirements.
Clause F4 Safety from falling: Performance F4.3.1, F4.3.4
· F4 Safety from falling: Metroglass IGUs can be manufactured in accordance with NZS4223.3 clause 21 Window glazing safeguarding a fall, to the specific project requirements.
Clause G7 Natural light: Performance G7.3.1, G7.3.2
· G7/AS1 Natural Light: Metroglass IGUs can be manufacturedto comply with the building code or to the required Visible Light Transmittance (VLT) of the IGUs specifiedto the project specific requirements. design.
Clause H1 Energy efficiency : Performance H1.3.1
· H1 Energy Efficiency: Metroglass IGUs can be manufactured to project specific centre of glass thermal transmittance (Ugw). They are made from a range of glass types (i.e., Low E coated glass, float glass, laminates, obscures, tints), spacer widths and argon gas, which establish the IGU U-value to EN673, which ultimately is utilised to calculate the window R-value (by others).

- B2 Durability: Metroglass IGUs are manufactured to Acceptable Solution B2/AS1 and are tested by IGUMA to BS EN 1279–4 in accordance with NZS4223.2

- E2 External Moisture: Glass is impervious to water. Adequate drainage is required in the glazing system

- F2 Hazardous Building Materials: Metroglass IGUs likely to be subject to human impact safety can be manufactured to specific project requirements to comply with NZS 4223.3 in accordance with F2/AS1 clause 1.0

- F4; G7/AS1; H1 Metroglass IGUs can be manufactured in accordance with NZS4223.3 clause 21 or to the required Visible Light Transmittance (VLT) and/or Metroglass IGUs can be manufactured to project specific centre of glass thermal transmittance (Ugw)

Evidence

The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:

Metroglass IGUs are manufactured for, but not limited to, use in projects within the following scope:

· All building types located at less than 800m[AG1] above sea level. · All NZS3604 wind zones up to and including extra high. · Site specific design wind pressures above the NZS3604 windzone values (subject to design checks and confirmation). Metroglass IGUs are customer manufactured to the requirements of each project. Prior to manufacture, the following project criteria are validated and confirmed by the purchaser: · IGU size · IGU thickness · Glass thickness and type · Project wind zone or specific engineering design factored wind pressure · IGU performance criteria, i.e. U-value, Solar Factor, VLT, Safety Glass requirements, colour considerations For guidelines see IGUMA IGU design limitations [AG1]I couldn’t find anything that refers to sea level. Is this a limitation or can we go right to sea level?
