PU panels — polyurethane (PUF) sandwich panels — are the premium insulated panels for cold storage, clean rooms, and prefab buildings where maximum insulation in minimum thickness is required. As a top PU panel manufacturer, Thermo Master supplies PUF panels from our factory on Katar Band Road, near Thokar Niaz Baig, Lahore, delivering across Pakistan since 2017.
With the lowest thermal conductivity of any panel core (0.022 W/mK), a 100 mm PU panel insulates like 150 mm of EPS — critical where every inch of cold-room space earns money.
What PU Panels Are and How They Work
A PU sandwich panel is polyurethane foam injected between two PPGI steel facings, bonding into a single rigid unit. The foam’s fine closed-cell structure delivers R-6.5+ per inch — the highest of any sandwich panel. Panels come 30–200 mm thick with cam-lock joints for airtight cold-room assembly, 1 m wide, up to 12 m long.
