Thermal and Acoustic Performance in a Single Skylight Solution

When architects and engineers are tasked with designing energy-efficient industrial buildings, the roof is more than just shelter — it’s an opportunity to improve thermal performance, reduce energy costs, and introduce controlled natural light.

At the Kangy Angy Train Maintenance Facility on the NSW Central Coast, Ampelite’s Energy Efficient Factory Assembled Skylight (EEFAS) system was specified across 3,000m² of roof area to meet demanding performance and compliance standards for a 24-hour, heavy-duty rail environment.

Designed to integrate seamlessly with insulated panel roofing systems (Askin, Bondor, Kingspan, and more), EEFAS offers advantages that traditional skylights simply can’t deliver.

Key Benefits:

1. Thermal Efficiency: U-value of 1.6 W/m²K and SHGC of 0.14 to meet NCC Section J compliance.
2. Acoustic Control: Rw rating of 31dB thanks to integrated Acoustic Plus technology — critical for a site adjacent to residential areas.
3. Structural Integrity: Webglas GC® is rated as trafficable and requires no safety mesh, a major advantage in sandwich panel construction.
4. Glare-Free Daylight: Clear LEXAN THERMOCLEAR polycarbonate provides high light transmission without harsh shadows or heat build-up.
5. Factory-Assembled Quality: Built to exact project dimensions, airtight, and sealed with fire-retardant foam to match panel thickness — reducing onsite complexity and install time.

EEFAS is a fully compliant solution under NCC 2019 Part J1.4, designed for Class 2–9 buildings with a minimum roof pitch of 2 degrees. It’s a smart option for architects and designers working on large-scale transport, industrial, or education facilities where thermal compliance and visual comfort must work hand in hand.
