Rainscreen Drainage Planes
SC 5016 and SC 5032 are 0.024" (0.6 mm) thick high impact polystyrene sheets. They are formed with 3/16" corrugations and a spunbond polypropylene fabric on one side with a 4" (102 mm) skirt on one edge.
May be referred to in specifications as channeled and perforated high impact polystyrene with an adhered fabric as an intervening drainage medium behind stucco and scratch coat systems.
Can be used in place of three-dimensional matrix of monofilament fibers with adhered fabric.
Gravity Cavity™ rainscreen drainage plane (drainage mat) is the economy alternative to our Sure Cavity® drainage plane (drainage mat) product. It works because it maintains a separation between the materials used for the veneer and the structural back-up wall to drain incidental moisture and dry out the building enclosure. Gravity Cavity™ drains and dries better than mesh-based drainage matrix products because its 1/8” deep channels enable moisture that enters the building envelope to travel quickly straight down and out the bottom of the wall, and it won’t compress behind siding.
Features & Benefits
True channels conduct moisture to the bottom of walls faster than other rainscreen drainage mat products
High impact polystyrene ensures durability and prevents compression, waviness, and nail drive-through experienced with fiber-based mesh products
Saves installation time (half the time of furring strips and backer board)
96% pre-consumer recycled content
The adhered fabric blocks mortar or stucco from filling the drainage channels and acts as a bug screen at the bottom

SCMM 2516 and SCMM 2532 are 0.024″ (0.6 mm) thick high impact polystyrene sheets. They are formed with 10mm corrugations and a spunbond polypropylene fabric on one side with a 4″ (102 mm) skirt on one edge.
May be referred to in specifications as channeled and perforated high impact polystyrene with an adhered fabric as an intervening drainage medium behind stucco and scratch coat systems.
Can be used in place of three-dimensional matrix of monofilament fibers with adhered fabric.

Weeps work when they create a path for drainage at the lowest point in the cavity wall - in this case, directly on the lintel or shelf angle flashing. Head Joint Weeps are 3/8" wide - the same as a mortar joint - so they act as a time-saving spacer for creating great looking brick joints.

The MTI Retrofit Weep™ system is the one and only COMPLETE Retrofit weep system. The MTI Retrofit Weep™ allows moisture to exit the brick veneer from the brick cavity to the exterior of the structure. This system is designed to be used with MTI’s Retrofit Brick Tie™ system. The MTI Retrofit Weep™ system is an inexpensive alternative solution for a restoration project.

Compatible building materials keep projects moving along on-time and on-budget. MTI Edge Metal is designed to accommodate the depth of the Sure Cavity™ rainscreen drainage plane on vertical and non-draining terminations.

When it comes to moisture intrusion windows are frequently the weak point in wall assemblies. Any opening or protrusion in the wall that interrupts the drainage plane requires a moisture management plan and good detailing. The Moisture Diverter™ integrates with the rainscreen drainage plane and moves the moisture away from the opening, modify the risk.

Keeping a clear cavity for drainage & ventilation in brick walls is essential for the long-term performance of the wall - holding the mortar 10" above the weeps isn't enough. Use Trash Mortar Diverter to catch mortar squeezings and keep a functioning cavity in brick veneers.

Drainage removes bulk liquid moisture from a wall, but a little moisture can still do a lot of damage. The key to drying out a wall assembly is to ventilate the rainscreen drainage gap. Vent Strip ventilates a brick cavity wall below the shelf angle to keep your walls dry and sustainable.
