ISOKING Rock Wool Board with Aluminum Foil takes our standard basalt rock wool core and adds a high-quality aluminum foil facing—an easy upgrade that cranks up performance big time. The foil layer supercharges thermal insulation, locks out moisture and dust, and even makes the board smoother and easier to handle during installation. It’s a go-to pick for HVAC ducts, wall cavities, and roof insulation where you need that extra layer of protection and efficiency.
MOQ-1*40HQ Container
ISOKING Rock Wool Board with Aluminum Foil combines the fire-resistant, sound-dampening core of our classic basalt rock wool with a smooth, tight-fitting aluminum foil facing. The foil isn’t just a surface layer—it acts as a powerful vapor barrier, stopping moisture from penetrating the rock wool and keeping its insulation performance intact for years. It also reflects heat back into the space, cutting down on energy loss way more than regular rock wool boards.
Our rock wool board super tough—perfect for industrial pipelines and ceiling insulation projects! The foil facing stays nice and flat when you’re installing it, hardly tears at all, and even gives it a clean, polished finish that blends right in with other building materials.

Industrial Workshops
Go-to pick for workshop wall and roof insulation. That aluminum foil layer? It’s a game-changer for heat reflection—keeps your space cool when it’s scorching outside, and locks in warmth when it gets chilly. Plus, it’s tough against moisture, so the rockwool core stays in top shape, no fade-out on performance over time.
Commercial & Residential Buildings
Our rock wool board is perfect for exterior wall insulation projects. Slashes your heating and cooling bills big time, plain and simple. The aluminum foil blocks out water vapor too—saves your wall structure from damp damage. And let’s not forget the fire resistance—it adds a solid safety layer to any building.
Cold Storages & Freezers
Ideal for low-temp insulation needs. The rockwool itself is amazing at holding in the cold, and the aluminum foil wraps it up in a tight, moisture-proof seal. That means your cold room stays steady at the right temp, and your refrigeration equipment uses way less energy.
