Yes. Larger windows generally require more frame material, more glass and additional manufacturing time.

Size can also affect the structural requirements of the system. Larger panes may need thicker or higher-performing glass, reinforced profiles or specialist lifting equipment during installation.

The proportions matter as well. A particularly tall, wide or narrow window may require more detailed engineering than a conventional rectangular opening.

Fixed windows are usually simpler than windows containing opening sashes, hinges, handles, locks and seals.

Opening styles may include:

• Inward-opening windows
• Outward-opening windows
• Sliding systems
• Shaped or curved windows

Each moving component introduces additional manufacturing, hardware and alignment requirements. 2K’s brass window range includes fixed, inward-opening, outward-opening and sliding systems, with shaped and curved configurations also available across selected systems.

The glass can make up a significant part of the overall window specification.

Cost will vary depending on whether the project requires:

• Double or triple glazing
• Low-emissivity glass
• Laminated safety glass
• Toughened glass
• Acoustic glazing
• Tinted or patterned glass
• Oversized glazing panels

New Zealand guidance recommends assessing the glass and frame as a complete window system. Factors such as climate, orientation, noise, heat loss and coastal exposure can all influence the most suitable glazing choice.

2K’s brass window systems support double glazing, while selected sliding profiles can accommodate thicker triple-glazed units where stronger thermal, acoustic or safety performance is required.

It can.

The desired appearance may require additional finishing work during fabrication. Options might include a polished, brushed, aged or patinated appearance, depending on the system and project brief.

A natural finish designed to change over time may require a different process from brass intended to remain bright and consistent. Protective coatings or specialist surface treatments can also add to the initial cost and may create future maintenance requirements.

The finish should be confirmed before manufacturing begins, particularly when windows need to match brass doors, fittings or other metalwork.

Rectangular windows are generally more straightforward to produce than curved, arched or unusually shaped frames.

Cost may increase when the design includes:

• Curved or shaped profiles
• Complex glazing divisions
• Narrow or unusual proportions
• Custom glazing beads
• Bespoke handles and hardware
• Connections to brass doors
• Detailed junctions with other materials

2K’s brass systems can be customised with tailored dimensions, finishes, glass options and architectural details, allowing the joinery to be designed around the building.

The more specialised the design, the more time may be required for drawings, coordination, fabrication and quality control.

Handles, hinges, locks and opening mechanisms all contribute to the total cost.

Hardware selection may be influenced by:

• Window weight
• Opening style
• Security requirements
• Exposure to weather
• Desired finish
• Frequency of use
• Compatibility with the frame system

A large opening sash may require heavier-duty hardware than a smaller window. Bespoke or finish-matched fittings may also cost more than standard components.

Installation can vary considerably between projects.

A simple ground-floor window with easy access will generally be less complex than a large glazed unit being installed on an upper level, a constrained urban site or an exposed property.

Installation costs may be influenced by:

• Site access
• Scaffolding or lifting equipment
• Window size and weight
• Opening preparation
• Flashing and waterproofing
• Frame alignment
• Integration with the cladding
• Protection of the finished brass
• Travel and transport requirements

Correct installation is critical to weather resistance, airtightness, alignment and smooth operation. 2K provides installation for brass window systems and coordinates the frames with the surrounding building envelope.

Yes. Brass does not need to be specified for every window in a building.
It may be used selectively for:
A feature entrance
Street-facing windows
A main living space
Internal courtyard glazing
A hospitality frontage
A heritage feature
A window and door combination
Using brass in key areas can create a strong architectural result while allowing other window materials to be used elsewhere.
This approach can be particularly useful when the project has a defined budget but still requires a distinctive feature.

The more detail available at the quoting stage, the more accurate the estimate is likely to be.

Useful information includes:

• Architectural drawings
• Window schedules
• Opening dimensions
• Fixed or opening requirements
• Preferred brass finish
• Glazing requirements
• Hardware preferences
• Site location
• Access conditions
• Expected installation timing

Early involvement also allows potential design or installation issues to be identified before they create additional cost.

Custom brass window pricing reflects the complete system rather than the frame material alone.

Size, glazing, thermal performance, finish, hardware and installation all need to be considered together. A simpler fixed window may have a very different cost from a large thermally broken sliding system with specialist glazing and bespoke detailing.
