The only problem I have is that the supplied vapor wrap it only about 2 inches wide and bunches up easily. I found buying a clear vinyl drop cloth and cutting it into 8 inch strips is much more easily use for vapor wrapping. ## Frequently Bought Together - Thermwell Products SP46 Fiberglass Pipe Insulation Kit - Frost King HC3A Automatic Electric Heat Kit Heating Cables, 3 Feet, Black - Frost King Foil Backed Fiberglass Pipe Wrap, 3"x1"x25' --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/92775177-products-sp46-fiberglass-pipe-insulation-kit](https://www.desertcart.us/products/92775177-products-sp46-fiberglass-pipe-insulation-kit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-15*
