Rainscreens, Weeps and Moisture Management

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

Protection from Incidental Moisture behind

• Thin Stone & Thin Brick

• Fiber Cement & Cedar Siding

• Natural Stone

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.

For Brick Veneers & Single Wythe Masonry

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.

Features & Benefits

Tuckpoint Retrofit Weeps are the solution for drainage with oversized masonry units as well as renovations where mortar is removed to add weeps.

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.

The MTI Advantage

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.

The Retrofit Brick Tie was developed for flooded homes. The Retrofit Brick Tie allows the brick veneer to be anchored to the stud framing from the interior.

The MTI Advantage

• First Interior Applied Retrofit Brick Tie

The sub sill region of windows is an especially moisture-sensitive area. MTI's Window Drainage Plane™ allows moisture to escape from the sub sill area before it can cause problems.

The MTI Advantage

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.

The MTI Advantage

• Holds & Encapsulates Trash Mortar

• Funnels Moisture to Bottom of Cavity

• Lightweight, But Not Fluffy

• Easy to Install

• 100% Recycled Content

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.
