After 15+ years in the cold storage industry, we've seen the same mistakes repeated across projects. Here are the most common — and how to avoid them.
1. Undersizing the Refrigeration Unit
Many contractors save money by installing a smaller compressor. Result? The unit runs continuously, never reaches target temperature, and burns out early. Always calculate load properly — our Cold Store Calculator can help.
2. Poor Panel Joint Sealing
Even a 1mm gap between panels creates thermal bridging and ice formation. Use proper cam-lock systems and apply sealant on both sides.
3. Ignoring Floor Insulation
Cold rooms lose 15-20% of cooling through uninsulated floors. Always install minimum 50mm PUF or XPS under the floor slab.
4. No Vapour Barrier
In high-humidity areas like Karachi, moisture penetrates panels and freezes inside the core, destroying insulation. Always install a vapour barrier on the warm side.
5. Wrong Panel Orientation
Panels should always be installed vertically for walls, with the male joint facing away from prevailing winds.
Conclusion
Most cold storage failures are preventable. Invest in proper design and installation — it pays for itself many times over.
