Extreme Roofing: Interlock Selected for Antarctic Science Base
Antarctica SPOT MODULE Project — McMurdo Station
When it comes to building in the harshest environments on Earth, every material choice matters. That’s why Interlock Metal Roofing was chosen as part of the SPOT MODULE Project in Antarctica—an initiative supporting the South Pole Overland Traverse (SPoT), a critical logistics mission resupplying the Amundsen–Scott South Pole Station.
The Challenge: Building for Antarctica
Antarctica presents extreme conditions—temperatures plummet well below freezing, and winds can reach speeds exceeding 100 mph. Structures must endure these elements while providing reliable shelter for crews undertaking the two-month, 1,000-mile SPoT journey across the ice. The NSF and the United States Antarctic Program (USAP) needed modular units that were:
- Insulated and portable
- Capable of withstanding severe cold and wind
- Lightweight yet structurally robust
The Solution: Interlock Metal Roofing
After rigorous evaluation, Interlock Metal Roofing was chosen for both the roofing and siding of the SPOT MODULEs. Key factors influencing this decision included:
- Exceptional performance in extreme temperatures
- High wind resistance and structural reliability
- Lightweight, corrosion-resistant aluminum construction
These attributes ensure the modules can be towed across glacial terrain without compromising integrity or safety.
The Design: Modular Innovation by Yardstick Studio
Yardstick Studio Architecture was tasked with designing these Arctic-ready modules. Their approach combined innovation with practicality, resulting in structures that meet the rigorous demands of Antarctic expeditions. The collaboration between Yardstick Studio and Interlock Metal Roofing exemplifies how thoughtful design and superior materials can overcome environmental challenges.
At sunrise on the Antarctic Plateau, SPOT MODULE units outfitted with Interlock Metal Roofing are towed across the ice during the South Pole Overland Traverse—demonstrating resilience in one of Earth’s most unforgiving environments.
A Testament to Durability
Interlock’s involvement in the SPOT MODULE Project underscores its commitment to engineering roofing solutions that perform under the most demanding conditions. Whether facing the icy expanses of Antarctica or the varied climates of North America, Interlock Metal Roofing delivers durability, reliability, and peace of mind.

Antarctica Roofing FAQ - SPOT MODULE Project
What is the SPOT MODULE Project in Antarctica?
The SPOT MODULE Project is a groundbreaking initiative by the U.S. National Science Foundation (NSF) and United States Antarctic Program (USAP) to create six modular structures for the South Pole Overland Traverse (SPoT). These modules serve as mobile living quarters, sleeping areas, and operations bases for crews traversing the 995-mile route between McMurdo Station and the Amundsen-Scott South Pole Station. Interlock Metal Roofing was selected to provide both roofing and siding for these critical structures.
