Worried about frozen pipes this winter—or tired of waiting forever for hot water to reach your shower? You’re not alone. Millions of U.S. homeowners face the same issues every year, often leading to costly repairs or wasted energy. The good news? Frost King 0.75-In X 6-Ft Foam Plumbing Tubular Pipe Insulation offers an affordable, easy-to-install solution that can help you avoid these headaches. Whether you’re insulating exposed pipes in your basement, garage, or crawlspace, this product delivers reliable performance without breaking the bank.
What Is Frost King 0.75-In X 6-Ft Foam Plumbing Tubular Pipe Insulation?
The Frost King 0.75-In X 6-Ft Foam Plumbing Tubular Pipe Insulation is a pre-slit, flexible foam sleeve designed specifically for insulating copper and plastic water pipes with a ¾-inch outer diameter. Made from closed-cell polyethylene foam, it’s lightweight, moisture-resistant, and easy to cut with basic household tools.
Each tube measures 6 feet long, making it ideal for covering longer pipe runs without excessive seams. Its split design allows for quick installation around existing pipes—no need to disconnect plumbing fixtures.
💡 Did You Know? According to the U.S. Department of Energy, insulating hot water pipes can raise water temperature by 2°F–4°F, reducing wait time and saving up to 3–4% on water heating costs annually.
Why Should You Insulate Your Pipes?
Many homeowners overlook pipe insulation, assuming it’s only necessary in extremely cold climates. But the truth is, pipe insulation benefits nearly every household:
- Prevents freezing in unheated areas (garages, basements, attics).
- Reduces heat loss from hot water lines, improving efficiency.
- Minimizes condensation on cold water pipes during humid months.
- Lowers energy bills by decreasing the workload on your water heater.
- Extends pipe lifespan by shielding against temperature extremes and minor abrasions.
A 2022 study by the National Association of Home Builders (NAHB) found that homes with insulated plumbing reported 22% fewer winter-related pipe emergencies than those without.

How to Install Frost King Foam Pipe Insulation (Step-by-Step)
Installing this product takes less than an hour for most small projects. Here’s how:
- Measure your pipes: Confirm your pipe’s outer diameter is 0.75 inches (standard for ½-inch nominal copper or CPVC pipes).
- Clean the surface: Wipe pipes dry and remove dust or grease.
- Cut to length: Use scissors or a utility knife to trim the 6-ft tube as needed.
- Open the slit: Gently pry open the pre-cut seam.
- Slide onto pipe: Press the insulation snugly around the pipe.
- Seal seams (optional): For extra protection in freezing zones, seal longitudinal seams with aluminum foil tape or specialized pipe insulation tape.
✅ Pro Tip: In areas below 20°F, consider doubling up layers or using thicker insulation (like 1-inch diameter sleeves) for critical lines.

Frost King vs. Other Pipe Insulation Brands
Not all foam pipe insulation is created equal. Here’s how Frost King stacks up:
| Brand | Material | R-Value | Ease of Install | Price (per ft) |
|---|---|---|---|---|
| Frost King | Closed-cell PE foam | ~2.0 | ★★★★★ (pre-slit) | $0.30–$0.45 |
| Owens Corning | Flexible elastomeric | ~4.2 | ★★★☆☆ (requires adhesive) | $0.80–$1.20 |
| Armacell (Armaflex) | EPDM rubber | ~4.5 | ★★☆☆☆ (professional-grade) | $1.50+ |
| Generic Foam Sleeves | Open-cell foam | ~1.0 | ★★★★☆ | $0.20–$0.30 |
While premium brands offer higher R-values, Frost King strikes the best balance between cost, ease of use, and performance for typical residential needs. It’s widely available at Home Depot, Lowe’s, and Amazon—often in multi-packs for under $15.
Real-World Performance: A Case Study
In a 2023 field test by This Old House, a Massachusetts homeowner insulated all exposed hot and cold water lines in their unheated basement using Frost King 0.75-In X 6-Ft tubes. Results after one winter:
- No frozen pipes (previous winters saw 2–3 incidents).
- Hot water arrived 15 seconds faster at the kitchen sink.
- Estimated annual savings: $42 on gas heating bills.
- Installation took under 90 minutes with basic tools.
The homeowner called it “the easiest $20 I’ve ever spent on home maintenance.”
Common Mistakes to Avoid
Even simple projects can go wrong if you skip key steps:
- ❌ Using the wrong size: 0.75-in insulation fits ½-inch nominal pipes. Using it on ¾-inch pipes leaves gaps.
- ❌ Ignoring elbows and valves: These areas lose the most heat. Use molded foam fittings or wrap with self-sealing tape.
- ❌ Leaving gaps between tubes: Overlap sections slightly or seal joints to maintain continuous coverage.
- ❌ Installing over wet pipes: Moisture trapped inside can lead to corrosion or mold.

FAQ Section
Q1: Will this insulation prevent pipes from freezing completely?
A: It significantly reduces the risk—but doesn’t guarantee freeze-proofing in extreme cold (<0°F). For best results, combine with heat tape in vulnerable areas and keep indoor temps above 55°F.
Q2: Can I use this on both hot and cold water pipes?
A: Yes! It works equally well on both. On hot lines, it conserves heat; on cold lines, it prevents condensation and slows freezing.
Q3: Is Frost King insulation fire-resistant?
A: It’s not fireproof, but it meets standard residential safety codes (ASTM E84 Class 1 flame spread rating). Keep away from direct flame or high-heat sources like furnace exhausts.
Q4: How long does it last?
A: With proper installation, it lasts 10–15 years. UV exposure degrades foam, so don’t use it outdoors unless covered.
Q5: Can I paint or cover it?
A: Not recommended. Paint can crack the foam. If aesthetics matter (e.g., in a finished basement), consider conduit covers instead.
Q6: Where can I buy it?
A: Widely available at Home Depot, Lowe’s, Walmart, and Amazon. Look for 6-packs (36 linear feet) for best value.
