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

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.

Used with Lip Brick Set in a Bed Joint of Mortar Applications

It creates a weep system that moves moisture out of and away from this sensitive detail. The Concealed Lintel Weep creates tunnel weeps beneath the bed joint mortar, where an effective weep should be!

The MTI Advantage

• Completely Hidden Weeps

• Weeps at Lowest Point in Wall

• 100% Recycled Content

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.

The MTI Advantage

Damp and dreary basement? Transform it into a comfortable living space with MTI's basement systems. Floor Edging separates the floor from walls and footings, creating a path for moisture to pass under the slab and to the drain field & drain tile system.

The MTI Advantage

Damp and dreary basement? Transform it into a comfortable living space with MTI's basement systems. Control Cavity maintains a separation between the masonry walls and moisture sensitive materials of finished walls and directs water to the drain field.

The MTI Advantage

Block basement walls are an economical choice but increase the risk of moisture penetration and damp basements. Vent Mat drains block cores into the drain field. Keep your basement dry with MTI's complete below grade moisture management systems.
