Phase-change storage
Shape-stabilised PCM absorbs and releases heat around a target temperature zone without free liquid leakage.
Science
How shape-stabilised PCM cartridges become a night-charged thermal battery.
Edge Comfort builds on the Passive Edge PCM platform, which solves two hard parts: PCM that does not leak, and high-conductivity paths that move heat in and out fast enough to matter in a DIY retrofit.
High-conductivity design
The core challenge is not only storing coolth, but moving heat in and out fast enough to matter through high-k fins.
Night charging
When outdoor night air is cool enough, fans and airflow channels help recharge PCM modules.
Day buffering
During the day, PCM absorbs indoor heat and helps extend comfort hours.
Performance depends on context
Every recommendation starts at room level.
Passive PCM cooling depends on local night temperatures, humidity, solar gain, ventilation behavior and building fabric. That is why Studio first sizes cartridges and then maps reuse parts, partner picks and optional off-peak recharge around the real room.
The platform is not cooling-only: cartridges come in a range of phase-change temperatures, from 22–26°C coolth packs to ~32°C heat-storage packs you can swap in for winter and charge off-peak with a small fan heater or air-source heat pump. And because PCM absorbs and releases heat at a nearly constant temperature, it damps indoor swings — rooms hold a steady, comfortable band around the chosen zone instead of cycling hot and cold.
