Our turn around time is 3-4 weeks from final site measure upon agreed sizes.

The “E” in Low E is an abbreviation of “Emissivity”, which is a measure of the ability to radiate absorbed energy. Low E glass has a special coating on the glass surface, which reduces the amount of heat transferred through the glass, improving its thermal performance. Som versions of Low-E Glazing also feature Argon Gas further improving thermal performance.

ThermalHEART joinery is a new series of thermally broken aluminium joinery which almost doubles the performance of standard aluminium windows and doors when paired with high performance Low-E Glazing.

R-values and U-values are both measures of thermal resistance used in building construction, particularly for windows. R-value and U-value are inverse measures of each other. Higher R-values indicate better insulation, while lower U-values indicate better insulation. Both values are important considerations when selecting windows for energy-efficient building design.

The revised H1 Building Code requires all residential Building Consents lodged after November 2023 to have joinery with a minimum R-Value of R0.46 in Auckland (Climate Zone 1). This is to ensure all homes in New Zealand will be warmer, drier, healthier and more comfortable.

Yes, our standard aluminium joinery series such as Residential Series, Metro Series and Architectural Series is still available.

If you're replacing an existing window or door that's older than 15 years old and does not exceed 2 storeys, you generally won't need building consent

Note: You'll need building consent if the original doorway or window was installed within the past 15 years and has failed and/or if the building exceeds 2 storeys.

Yes, Colonial Bars are still available under the new H1 Building Code. Although the IGU will need to be modified to compensate or the insulation in another part of the building’s envelople increased accordingly.

Yes, louvre windows are still an option under the new H1 Regulations. Although, the insulation in another part of the building’s envelople will need to increase accordingly.

Yes, skylwghts are still an option under the new H1 Regulations. Skylights have a specific set of performance requirements and are limited o either 1.5m2 or 1.5% o the total roof area. If a skylight is larger than the aforementioned figures, the thermal envelope will need to be compensated elsewhere.
