Shrink wrap might look simple — just plastic stretched over a building, right? But behind every successful installation is a blend of material science, engineering, and field-tested methodology that makes it far more reliable than tarps or temporary panels.
What Is Shrink Wrap Made Of?
Professional-grade shrink wrap used for disaster recovery isn’t the same plastic you’d find on a shipping pallet. It’s typically:
- 12 to 15 mil thick polyethylene
- UV-inhibited to resist sun degradation
- Fire-retardant rated for safety on rooftops or near HVAC units
- Formulated to shrink tight without tearing
Once heated, it conforms and tightens, creating a drum-like seal over any structure.
How It’s Applied
- Measurement & Prep: Crews measure and pre-cut wrap sections to fit the roof or wall surface precisely.
- Securing the Perimeter: Wrap is attached to the building using furring strips, strapping, or existing architectural edges.
- Heat Activation: Using propane-powered heat tools, the wrap is shrunk and tensioned. This process bonds seams and tightens the material until it fits like a glove.
- Edge Sealing & Venting: Final steps include sealing overlaps and installing vents to prevent moisture buildup inside the enclosure.
Why It Works So Well
Shrink wrap doesn’t just cover damage — it seals it. The bond is:
- Wind-resistant
- Moisture-blocking
- Long-lasting (often up to 12 months if needed)
And unlike tarps, it won’t flap, leak, or require constant re-tightening. It protects not just the structure, but the timeline of your recovery.
Shrink Wrap Is Engineering You Can Trust
Every wrap project balances material thickness, anchoring strength, temperature application, and ventilation. That’s why StormWrappers crews undergo specialized training — not just in application, but in understanding how to match each job to the right product and process.
