TRI-BUILT 2.00"–3.00" Tapered ISO Rigid Roof Insulation Panel, 4 ft. x 4 ft.
This TRI-BUILT tapered polyiso roof insulation panel is 4 ft. x 4 ft. and tapers from 2.00 in. to 3.00 in. thick, forming the high side of sloped insulation systems on low-slope roofs. Each panel is sold individually. Pair it with thinner taper classes to complete the slope run.
Key Features:
- Tapered Profile: Tapers from 2.00 in. to 3.00 in. for the upper end of drainage slopes.
- Rigid Polyiso: Rigid ISO foam adds both slope and insulation value to the roof assembly.
- 4 ft. x 4 ft. Panel: Square 4 ft. x 4 ft. panel format simplifies layout and staging.
- H Taper Class: The 2.00–3.00 in. thickness class suits steeper tapered-system runs.
- Sold Per Piece: Purchase exactly the number of panels the layout requires.

Frequently Asked Questions (FAQ):
Q: What is included?
A: One 4 ft. x 4 ft. tapered ISO panel tapering from 2.00 in. to 3.00 in. thick, sold as a single piece.
Q: What area does one panel cover?
A: 16 sq ft; divide the sloped field area by 16 to estimate panel count.
Q: Where does this taper class go?
A: The 2.00–3.00 in. class typically forms the high point of a slope run, per the tapered layout plan.
Q: How is the panel installed?
A: Lay it in the planned slope sequence and attach per the membrane manufacturer's instructions with approved adhesives or fasteners.
Q: Does it add insulation value?
A: Yes, it is rigid polyisocyanurate foam; the thicker high end contributes more thermal resistance than the thin edge.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Thicker taper classes like this 2.00–3.00 in. panel usually cap the high end of crickets and slope runs, so order them alongside the adjacent classes for a seamless plane. Check total assembly thickness at doors, curbs and edges, and verify fastener lengths for the thickest panel edge.
Use fall protection and safe panel-handling practices when installing roof insulation at height.
Order TRI-BUILT 2.00–3.00 in. tapered ISO insulation panels to finish the high side of your roof slope.
