TRI-BUILT 1.50"–2.00" Tapered ISO Rigid Roof Insulation Panel, 4 ft. x 4 ft.
This TRI-BUILT tapered polyiso roof insulation panel measures 4 ft. x 4 ft. and tapers from 1.50 in. to 2.00 in. thick to create positive slope for drainage on low-slope roofs. Each piece is sold individually. Pair it with adjacent thickness steps and a compatible membrane system to build a sloped insulation assembly.
Key Features:
- Tapered Profile: Tapers from 1.50 in. to 2.00 in. to promote roof drainage.
- Rigid Polyiso: Rigid ISO (polyisocyanurate) foam provides roof insulation with structural stability.
- 4 ft. x 4 ft. Panel: Each panel measures 4 ft. x 4 ft. for manageable handling on the roof.
- Slope Building: Laid in sequence, tapered panels form a crickets or slope system toward drains and scuppers.
- Sold Per Piece: Priced and sold by the individual panel so you can order exactly what the layout requires.

Coverage & How Much You Need:
Each 4 ft. x 4 ft. panel covers 16 sq ft of roof area. Calculate the field by the slope layout and order panels from the corresponding thickness classes to step the surface toward drains.
Fit and Compatibility:
Designed for low-slope roof assemblies; combine with other TRI-BUILT tapered ISO thickness classes and a compatible roof membrane, insulation adhesives or fasteners sold separately.
Frequently Asked Questions (FAQ):
Q: What is included in one order?
A: One 4 ft. x 4 ft. tapered ISO panel tapering from 1.50 in. to 2.00 in. thick, sold as a single piece.
Q: How much area does one panel cover?
A: Each 4 ft. x 4 ft. panel covers 16 sq ft; divide your roof field area by 16 to estimate panel count.
Q: How is tapered insulation installed?
A: Panels are laid in the specified slope sequence and attached per the membrane manufacturer's instructions with approved adhesives or fasteners.
Q: Why choose a tapered panel?
A: Tapered panels create positive slope so water drains toward scuppers and drains instead of ponding.
Q: Is the panel moisture resistant?
A: The panel is rigid polyiso foam; store it dry and protect it from weather until covered by the membrane.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tapered ISO assemblies are planned panel by panel: match this 1.50–2.00 in. class to the layout drawing so slope lines run continuously toward drains. Keep panels dry and flat before installation, and stagger joints when layering. Confirm R-value requirements with the membrane manufacturer, since polyiso ratings vary by thickness.
Handle panels with care on the roof and follow fall-protection requirements when working on low-slope roofs.
Order TRI-BUILT 1.50–2.00 in. tapered ISO insulation panels today to build positive slope into your low-slope roof.
