Choosing the right insulation for temperature control and energy savings in industrial sheds.
PUF (Polyurethane Foam) panels are sandwich panels with a rigid foam core between two metal sheets. They are the 'gold standard' for thermal insulation.
Glasswool is a fibrous material made from recycled glass. It is typically installed as a blanket underneath standard roofing sheets with a vapor barrier (foil).
| Feature | PUF Panels | Glasswool Blanket |
|---|---|---|
| Thermal R-Value | Very High (Best) | High |
| Fire Rating | B2 / PIR (available) | Class A (Non-combustible) |
| Installation Method | Tongue & Groove Joint | Underdeck Blanket |
| Moisture Resistance | 90%+ Closed Cell | Needs Vapor Barrier |
| Typical Use | Cold Storage / Clean Rooms | Factory Sheds / Commercial |
"If you are building a temperature-controlled cold room or pharmaceutical lab, PUF Panels are mandatory. For standard industrial sheds looking for heat reduction and noise control on a budget, Glasswool with a high-quality foil facing is the most cost-effective solution."
PUF Panels are all-in-one. You install the structural sheet and insulation in a single pass. This can reduce onsite labor time by 40% compared to traditional layered roofing.
Requires a two-step process: laying the mesh and glasswool blanket, followed by the top roofing sheet. While cheaper in material, it requires more labor and careful oversight to avoid compression of the wool.
A: Glasswool is significantly better for acoustic insulation. Its fibrous structure absorbs sound waves, making it ideal for noisy manufacturing plants or commercial buildings near airports.
A: Standard PUF is fire-retardant (B2 grade). For high-risk areas, we recommend PIR (Polyisocyanurate) panels which offer superior fire resistance and charring properties.
A: If installed with high-tension wire mesh and proper fasteners, glasswool will stay in place for decades. Inferior installation can lead to 'sagging' which creates thermal gaps.
