Expert Verdict — Reviewed by the SuperArbor Pro Desk
Prefabricated split boots save time and produce more consistent welds than hand-cut field boots, so keep several on the truck for penetrations. Match the boot to the pipe diameter and to the membrane thickness and color. Hot-air weld the seams and lap edges per the membrane manufacturer's flashing details.
Hot-air welding PVC produces heat and fumes; keep combustibles clear, wear gloves and eye protection, and follow the welding equipment's safety instructions.
Order the JM PVC Split Square Pipe Boot in white for quick, reliable flashing of square penetrations.
