Install Fiberglass Insulation Near Flue — Insulate Exposed Pipes: Prevent Freezing Temperatures
Part of project
Prevent Frozen Pipes: Winterizing Your Plumbing System · Step 1 of 2
In this video
Due to the heat from the exhaust flue, you must use non-combustible insulation for the sections of pipe closest to it. Take the unfaced fiberglass pipe wrap and carefully wrap it around the first 8 inches of both the hot water outlet and cold water inlet pipes. Ensure the wrap is snug but avoid compressing it tightly, as this can reduce its insulating R-value. Secure the end of the wrap with tape if necessary.
Goal: Safely insulate near heat source
- This step is critical for fire safety. Foam insulation is combustible and must not be used near the flue.

FAQs
What essential tools, besides the utility shears and caulk gun, will I need for this pipe winterization project?
You'll definitely need a sharp utility knife for precise insulation cuts and sturdy gloves for handling expanding foam. A headlamp can also be very useful for illuminating dark crawl spaces or basements, ensuring you don't miss any spots.
What are the most crucial safety precautions when using expanding foam and insulating pipes, particularly in confined areas?
Always wear safety glasses and gloves when applying expanding foam, as it can be very difficult to remove from skin and eyes. Ensure the work area is well-ventilated, and wear a dust mask if working in dusty or confined spaces like crawl spaces to avoid inhaling particulates.
How can I ensure the pipe insulation is applied correctly to maximize its effectiveness and prevent cold spots?
The key is to ensure continuous coverage without any gaps. Butt insulation pieces tightly together, and use your utility shears or knife to carefully miter cuts around elbows and corners for a snug fit. Secure self-seal insulation properly, or use appropriate tape for other types.
Is this project truly beginner-friendly, and what's a realistic expectation for material costs?
Yes, this project is very beginner-friendly, focusing on straightforward tasks like sealing and insulating. The 4-hour time estimate is achievable for an average home, and material costs are typically low, often ranging from $50-$100 for basic foam insulation and expanding foam, depending on the linear feet of pipe.
