Double Glazing for Builders & Developers
Supply, Specification and Site Coordination for Perth Development Projects
Builders and developers face a specific set of glazing pressures that standard residential supply chains are not set up to handle: multiple dwellings with identical specifications, a construction programme that cannot flex around late deliveries, and a client or end-buyer who expects the same finish and performance in every unit. Penot works directly with project teams across Perth on exactly this kind of brief. We supply and install double glazed windows and doors across townhouse, grouped housing and apartment projects, with the lead-time discipline, specification consistency and site coordination that volume work demands.
Why Perth Project Teams Work with Penot
Project glazing fails for predictable reasons: quoted lead times that slip, units delivered out of spec, installers who cannot coordinate with the broader site programme. We have built our project delivery model to address each of those failure points directly.
We confirm manufacturing and delivery schedules at order, not on request, so your site manager can programme glazing into the build sequence without holding a contingency week.
Every unit across a multi-dwelling project is manufactured to the same spec: same frame system, same glass type, same hardware, same finish. No lot-to-lot variation.
We liaise with your site supervisor directly, not through a sales layer, so delivery windows, access requirements and installation sequencing are confirmed before crews arrive.
We provide the product compliance documentation your certifier needs, including AS 2047 data, energy performance figures and, where required, BAL-29 certification.
Site Coordination and Scheduling
Multi-dwelling projects need glazing installed in sequence, not in one batch. We work within your construction programme: staging deliveries by lot or level, arriving when the frame is ready rather than when it suits us, and completing each stage so following trades can proceed without delay.
We engage early to understand your project’s scope, budget, and design specifications, offering expert double glazing advice during the planning phase.
Receive comprehensive, transparent quotes. We can also explore value engineering options to meet project budgets without compromising on critical performance.
Your double glazed windows and doors are manufactured to exact specifications, undergoing stringent quality checks before dispatch to your Perth site.
We work closely with your site managers to schedule deliveries and installations, ensuring our certified teams work efficiently and safely, respecting your project timelines.
Our commitment extends beyond installation, providing full warranty support and all necessary compliance documentation for a smooth project handover.
Getting the Performance Specification Right
Getting glazing performance right across a whole project matters beyond the quality of individual units. The glass specification affects energy ratings for the NCC Section J submission, acoustic ratings for dwellings near roads or rail, and bushfire compliance for developments in BAL zones. We work through the performance requirements at the specification stage, not after.
We can specify glazing to target performance levels that support your Section J compliance pathway, providing the thermal performance data your energy assessor needs.
For dwellings in noise-affected corridors, we specify laminated acoustic glass units rated to the project's acoustic report, and provide the STC/Rw documentation.
Developments in designated bushfire-prone areas need glazing that meets BAL-29 requirements. We supply compliant units and provide the certification for your building permit.
All windows and glazed doors we supply are tested and certified to AS 2047. We provide the certification documentation required at inspection.
Project Types We Service
We supply and install across a range of development types in Perth. The common factor is a project team that needs glazing handled without adding management overhead.
Technical Support at Every Stage
Builders and developers working on tenders or design development need more than a price. We provide the technical documentation your team needs at each stage of the project.
Full technical data for every double glazed window and door system we supply, formatted for inclusion in tender documentation and project specs.
Thermal performance values and acoustic ratings for each glass specification, ready to hand to your energy assessor or acoustic consultant.
Frame section drawings in standard CAD formats for inclusion in architectural documentation and building permit submissions.
A single contact who knows your project from tender through to installation sign-off. Not a call centre. Not a rotating team. The same person, start to finish.
Common Questions from Builders & Developers
- When should we engage Penot in the project timeline?
As early as design development, ideally before the tender package is finalised. Engaging early means we can confirm the specification, provide accurate pricing for the tender, and lock in manufacturing lead times before your construction programme is set. Late engagement is the main cause of glazing-related programme delays on multi-dwelling projects.
- How do you handle consistent specification across a large number of dwellings?
We manufacture each project to a single approved specification sheet agreed with your project manager before production starts. Frame system, glass type, hardware and finish are locked before the first unit is made. If the spec changes, that is handled as a variation with a written confirmation before production is updated. This removes the lot-to-lot inconsistency that happens when specifications are managed informally across a long project.
- Can you stage deliveries to fit our construction programme?
Yes. Staged delivery by lot, level or stage is standard on our multi-dwelling projects. We confirm the delivery sequence and access requirements with your site supervisor before manufacture starts. If the programme shifts, we work with you to adjust the delivery schedule where manufacturing lead times allow.
- What compliance documentation do you provide?
We provide AS 2047 certification for all windows and glazed doors, thermal performance data for Section J compliance, acoustic ratings where specified, and BAL-29 certification for bushfire-zone projects. All documentation is provided in a format suitable for building permit submissions and certifier review. Call 1300 121 603 to discuss the documentation requirements for your specific project.
- How does Penot coordinate with other trades on site?
We confirm access and sequencing with your site supervisor before we arrive, and we work within the daily programme rather than requiring a dedicated day. Our installation teams are experienced on construction sites and understand the expectation that they fit around the broader programme, not the other way around.
- Do you offer a warranty on project supply?
Quality aluminium frames carry a 10-year frame warranty. The full scope of the warranty is set out in writing before any order is confirmed. We do not apply different warranty terms to project supply versus residential work.
- Can you supply glazing for a project that has an architect or designer already engaged?
Yes, and we work with the design team regularly. If an architect or interior designer is already specifying the glazing, we liaise directly with them on technical details and provide samples, specification data and CAD drawings as needed. See our architects and designers page for how we support the design side of a project.
- Where can I find out more about Penot's approach to new builds?
Our new builds expertise page covers how we work on individual new home projects. For the glazing performance considerations that apply to both new builds and developments, the new builds hub is a useful starting point. For project pricing or a consultation on your development, call 1300 121 603 or use the contact form above.
