Building a cold storage in Pakistan — for fruit, dairy, meat, or pharma — lives or dies on insulation. Get it wrong and your refrigeration runs non-stop, electricity bills explode, and product spoils. This guide covers what actually matters.
Why Insulation Decides Your Running Cost
A cold room is a battle against heat leaking in through walls, ceiling, floor, and doors. Every watt of heat that enters must be pumped out by your refrigeration. Good insulation (correct material + correct thickness + sealed joints) can cut refrigeration load by 30–50% — the difference between a profitable cold store and a money pit.
Best Insulation Materials for Cold Storage
| Material | Typical Thickness | Where Used |
|---|---|---|
| Jumbolon XPS boards | 3″–5″ (75–125 mm) | Walls, ceiling, floor — the professional standard |
| PUF panels | 80–150 mm | Pre-fabricated cold rooms |
| Thermopore EPS | 4″–6″ | Budget cold rooms, chillers (not freezers) |
For freezer rooms (-18°C and below), 4″–5″ XPS is the standard specification. For chillers (0–4°C), 3″ XPS or 4″+ EPS works. Thermo Master manufactures jumbolon XPS up to 5″ thick — see our cold storage insulation service.
5 Costly Mistakes to Avoid
- Thin insulation to “save money” — you pay for it every month in electricity, forever
- Unsealed joints — gaps between boards leak more cold than the boards themselves save; seal every joint
- Ignoring the floor — ground heat rises; insulate the floor slab too, with high-compressive boards
- Cheap doors — an insulated room with a leaky door is a joke; invest in proper cold-room doors with heaters
- No vapour barrier — moisture condensing inside insulation destroys its performance; seal the warm side
What Size Cold Store Do You Need?
Rule of thumb: one tonne of apples needs roughly 35–40 cubic feet of well-racked cold room. Plan 20% extra space for air circulation — packed-tight rooms develop hot spots. Tell us your product and tonnage on WhatsApp at 0333-4673836 and we’ll size the insulation for you.
FAQs
How thick should cold storage wall insulation be? 3″–4″ XPS for chillers, 4″–5″ for freezers in Pakistan’s climate.
Can I convert a normal room into a cold store? Yes — line walls, ceiling and floor with XPS boards, add a refrigeration unit and insulated door. We guide contractors on this regularly.
How much does cold storage insulation cost? Depends on size and temperature — share your room dimensions and target temperature on WhatsApp at 0333-4673836 for a project quote.
