A 14.5 oz fiberglass lagging canvas that is easily installed over pipe insulation to conceal the fibers that may be considered a health concern if airborne.
The lagging canvas is made out of fiberglass cross woven thread that is embedded with an inorganic rewettable coating. Once moistened, the rewettable coating becomes sticky and hardens once it dries.
This product is tested to withstand a maximum operating temperature of up to 1000F.
SPECIFICATIONS: Meets Military Specification: MIL-C-20079H Type 1 Class 4
Per Yard: 60" wide x 3ft long* (for less than 5 yard orders)
Per Box (5 yards): 60" wide x 15ft long
Discounted Price per Box: $50
*Note: Per Yard orders are not cut individually, if you order 3 yards, you will receive a 9ft long section
WARNING: Asbestos is a health hazard. Proper precautions should be taken at all times when working with or near asbestos containing materials including wearing a respirator and properly sealing off the work area from other parts of the building.
*Product Quantity Estimation: Please feel free to email us the dimensions of your pipe and we will calculate the total number of yards that are needed for your project.

My basement hot water heating pipes are insulated. although the insulation is in good condition, it may contain hazardous fibers. So, I decided to cover it with this rewettable canvas rather than remove it. Until you gain some experience applying it can be a little messy, but you catch on quickly. Narrow strips are good around corners. The result is I now have a hard shell around the insulation that I will eventually paint. I would recommend this application if your heating pipes are insulated with older insulation that is still in good condition. This in my opinion much easier and less expensive than removing and then re-installing new insulation.

Used according to the directions and found it worked nicely. A plastic sheet on the floor might be advisable. Disposable gloves strongly recommended. Seems to have solved the issue.
*Kathleen, thank you for your review and your tip on protecting the floor which makes cleanup much easier. ~ BIP

Jonathan walked me through what I needed to purchase to satisfy my home buyer's request that I cover the asbestos pipes in the basement. The material was perfect, easy to apply with Jonathan's instructions and became rock-hard on completion. Can't imagine anyone else who could be so helpful with such a great product. Thanks so much.
**Sandy, thanks for the great review and compliments ~ BIP

I used the cloth to encapsulate the asbestos insulation on the old heating system piping in my basement. Some tips:
- Be sure to use a respirator when working on the asbestos piping as some fibers will likely come off as you do the encapsulation - I found the North Half Face Mask with P-100 North HEPA Filter Cartridges worked well. I also used latex gloves.
- For going around bends or dealing with difficult configurations, I recommend cutting strips about 2 inches wide and winding them around the pipe with substantial overlap.
- I recommend spraying instead of dipping, but make sure that both sides of the cloth are well saturated and glisten with water. I used a large plastic drop cloth underneath the area where I cut and sprayed as it is a messy operation.
- Before applying the cloth, I used water and a rag to clean off the worst of the many decades of dirt on top of the insulation which helped the cloth adhere to the insulation.
- To cut the pieces, I used a utility knife and straight edge with a board underneath and cut the 4 layers that had been folded together in the roll.
- Before cutting, try to align the different layers so that the fibers are parallel to the straight edge for the cut, otherwise, you will have a lot of strings of the fiberglass material unraveling to deal with after applying the cloth.
- Once cut to the size equivalent to the pipe diameter + 3-6 inches overlap, I cut the length of the unfolded piece in half (about 30 inches) since that is about the longest piece that can be applied without becoming unmanageable.
- Be sure to try to pull the cloth firmly around the insulation to minimize wrinkles and bubbles and then firmly smooth the exposed edge into the fabric that it is overlapping.
- Strings can be easily cut after the fabric becomes hard.
* Thank you for the great insight and extremely helpful tips on the install of the cloth. ~BIP

I found this product saved me a massive amount of money. The lagging was easy to apply through watching instructional video that was shown on this product. All my pipes passed inspection. Would recommend this product.
**We are glad you passed inspection! ~ BIP

I must say, when I read the details on this canvas I didn't know what to expect. I ordered 1 piece to tryout first and then ordered more once I felt comfortable that it would work. I did the spray bottle technique which I think is less messy than dipping the entire piece in water. Once damp the canvas becomes very sticky so you want to get it on wrinkle free because its not easy to reset. It took a day or so to fully dry, and it formed a hard cast which is rock hard. I was planning on painting over this but it looks good as is for now. Overall I am happy with the results although it took some time.
**Thanks for the tips and we are happy that the product worked for you ~ BIP
