Product Description
Each panel comes with steel facers on both sides. Thickness ranges from 0.4mm to 0.8mm. Inside, a high-density rockwool core (≥120 kg/m³, Class A) delivers the bulk of the insulation. The PU edge does more than just seal-it bonds the layers together, blocks thermal bridges, and keeps moisture away from the core. The result is a product that holds up well over time, resists air leakage, and stays strong under normal building loads.

Product Advantages
What makes PU Edge Sealing Rockwool Sandwich Panel stand out? Its core is Class A non-combustible, so it won't feed a fire. The low thermal conductivity of both rockwool and PU cuts down on heat loss, and the sealed edge stops air from moving through panel joints. That means no drafts, no water seepage, and no condensation inside the wall assembly. Builders also like it because it's light, easy to lift into place, and installs quickly.
Main Applications
You'll see this panel used across many building types. Industrial plants and steel-framed buildings use it for walls. Cold storage warehouses and cleanrooms rely on it for temperature stability. Commercial buildings, stadiums, and exhibition centers also install it where insulation and speed of construction matter. Even agricultural buildings-like greenhouses and livestock shelters-benefit from its durability.
FAQ
Q1: How thick should the panel be for my project?
A1: For cold storage rooms, go with 100–150mm. For standard wall applications in moderate climates, 50–75mm works fine. Just remember that thicker panels give you more insulation.
Q2: Does the PU edge keep water out completely?
A2: Yes, the PU material has a hydrophobicity rating of 98% or higher. It blocks moisture from getting into the rockwool core. However, good installation practices-like proper sealing at joints-are still necessary for full waterproofing.
