Aggre-flex Drainage is a mechanically attached Class PB (Polymer-Based) Exterior Insulation and Finish system (EIFS) applied over a code-approved water barrier and an approved substrate. This system offers several drainage cavity options, including a flat insulation board, drainage insulation board, or various drainage spacers up to and including Delta® Dry rainscreens.

Drainage track accessories may be used with the Aggre-flex Drainage System, or a backwrap method may be used.

Features and Benefits:

• High Insulating Value – about R-4 per inch.
• Exterior insulation reduces thermal bridging in framed walls and keeps masonry/concrete wall temperatures more consistent.
• The exterior lamina is monolithic, providing a continuous weather barrier with no breaks, but the secondary weather barrier can drain away any incidental moisture.
• Flat, wavy, or drainage mat or rainscreen options.
• LEED friendly and well suited to retrofit, renovation, and decorative upgrades.
