High-Performance Living in Westmere

Nestled in the vibrant Auckland suburb of Westmere, this striking multi-unit development by Warren Adolph Homes stands as a masterclass in modern urban densification. The Westmere project reimagines a standard residential site into three high-spec, three-story homes. The vision was clear: create sophisticated, healthy homes that maximize space on a compact footprint without compromising on the comfort and performance essential for modern New Zealand living.

The Formance Advantage

While these homes utilize traditional timber framing for the walls, the builders at Warren Adolph Homes made a strategic decision to use Formance SIPs for the most critical part of the thermal envelope: the roof.

In a multi-story home, heat loss through the ceiling is often the biggest contributor to high energy bills and uncomfortable indoor temperatures. By specifying 215mm thick Formance panels with an impressive R5.7 value, the project team ensured that the warmest air in the house stays exactly where it should—inside.

The benefits of the Formance roof system on this Westmere project are multifaceted:

• Superior Thermal Integrity: Unlike traditional insulation batts that can slump over time or leave gaps around complex rafters, the solid Steam Expanded Polystyrene (EPS) core of the Formance panels provides continuous, unbroken insulation. This virtually eliminates thermal bridging at the roofline.
• Airtightness where it Matters: The high pitch of these roofs creates a large surface area vulnerable to air leakage. The naturally airtight nature of Formance SIPs ensures that the "stack effect"—where warm air escapes out the top of a building—is neutralized, keeping the homes cozy even during Auckland's dampest winters.
• Structural Strength & Design Freedom: The inherent strength of the panels allowed for the large spans and dramatic raking ceilings seen in the master bedrooms. This structural capability minimized the need for heavy internal supports, keeping the architectural lines clean and the spaces open.
• A Quieter Sanctuary: Westmere is a bustling community. The solid core of the Formance roof provides excellent acoustic dampening, significantly reducing noise from heavy rain or overhead flight paths, ensuring the upper-floor bedrooms remain quiet retreats.

The Result

By integrating Formance SIPs into the roof structure, Warren Adolph Homes has elevated the standard for multi-unit developments. These Westmere homes prove that high-performance building doesn't have to be an all-or-nothing approach. By targeting the roof (the area of greatest potential heat loss) the builders have delivered a result that is approximately 60% more energy-efficient than a standard timber-framed home built to minimum.

The residents now enjoy homes that aren't just visually stunning, but are also healthy, exceptionally quiet, and cost-effective to run. It is a testament to how smart material choices can transform the living experience from the top down.
