This modification of the Pleko Therm System has all the properties that has made the Therm System the system of choice when it comes to PB Type EIFS Systems plus more.  The system allows the positive drainage of incidental water that may enter the system through various penetrations on the wall.

The system has by design redundant protection from water.  The primary weather barrier is the polymer modified base coat and the acrylic finish.  It incorporates a self adhering rubberized membrane that seals the edges around windows and other openings.   In addition it also incorporates a layer of 15# felt or 60 minute paper spread on the surface of the substrate to function as a secondary weather barrier.  The back of the foam insulation board is specially configured to incorporate vertical grooves that conducts water to the bottom of the wall and to the outside.

The secondary weather barrier over the approved substrate consists of a single layer of 15# felt, or minimum 60 minute paper, in conjunction with a rubberized, self sticking waterproof membrane for all penetrations, including doors and windows, outside and inside corners and for terminations at the bottom of the sheathing.

The rigid insulation board is made of 1.0 pcf. expanded polystyrene.  For the Rain Drain System the EPS foam insulation can range in thickness from 1 1/2 inch to 4 inches thick.  The insulation board forms the base of the system.

The Insulation Board used in the Rain Drain System incorporates a special configuration that allows the drainage of water through and out of the mechanically fastened EIF System.

The Insulation Board is chamfered 1/2 inch on the bottom edge as it rests on a PVC weep starter track to facilitate lateral drainage.

For added strength, an alkaline resistant woven fiberglass mesh is embedded in the base coat layer.  The mesh also prevents cracking, splitting or peeling of the finish coat.

PLEKO CEMENTITIOUS BASE COAT- An acrylic polymer modified cementitious base coat used for embedding fiberglass reinforcing mesh.

PLEKO NON-CEMENTITIOUS BASE COAT- An acrylic polymer based synthetic base coat.  Used for embedding mesh in the direct apply system using plywood and wood based boards also recommended for use in embedding high impact mesh.

PLEKO THICK BASE COAT- An acrylic polymer modified cementitious Base Coat, formulated with internal reinforcements and anti sag modifiers to allow thicker applications in just one pass.

Pleko’s exclusive fasteners hold the insulation board securely to the substrate.  The Pleko fastener must be used to conform to code requirements.   It withstands wind loading in multi-story applications.  These unique fasteners are available in a variety of sizes and styles to meet application needs.

These 100 % acrylic polymer based coatings stand up to all kinds of weather.  Available in a variety of textures and colors, they provide a tough, washable, protective coating.

ENERGY EFFICIENT

Installed directly over approved substrates, the Rain Drain System reduces air infiltration and leakage, while increasing exterior wall R-values.  That saves energy and creates a more comfortable environment.

DURABLE

Pleko Rain Drain System resists many of the elements such as ozone, ultraviolet radiation, salt water, freeze/thaw conditions and potential chemical attack which cause other coatings to crack, chip and fade.  For high traffic areas and special situations, a High Impact Rain Drain System is available.

COST EFFECTIVE

Easy installation, minimal material waste and optimum job site efficiency provide substantial initial savings over other kinds of siding materials.  Energy savings and low upkeep costs continue for the life of the building.

FLEXIBLE DESIGN

Pleko Rain Drain System's lightweight, simple installation and easy plan detailing offer unlimited design possibilities. Choose from a variety of textures and colors to complement your design.

ULTIMATE PROTECTION FROM WATER INFILTRATION

The Pleko Rain Drain System's design that incorporates redundant water protection is your ultimate guarantee of performance.  The system is designed to prevent water from getting into the substrate by providing drainage channels to the outside.
