Technical Datawedi Building Panel

2

OverviewThe original wedi Building Panel is engineered as a general purpose underlayment for tile with special added benefits that reflect a unique blend of traditional values for tilebackers: solid, sturdy and with a perfected cement-based resin surface for unmatched bond quality that can be achieved with any type of thinset mortar. But wedi has added state-of-the-art technology and the full experience that comes with more than 28 years of building panel manufacturing resulting in added benefits such as it’s internal waterproofness and zero capillarity; the ease of working or fabricating with the lightest building panel in a class of heavy duty use backerboards for tile; the dependable cement-base resin coating and fiberglass mesh for strength and durable bond. Unlike other foam boards in the market today, the wedi Building Panel cannot delaminate and is free of paper or cellulose layers and does not ignite or fuel fire. Unlike EPS (expanded polystyrene) foam boards, wedi Building Panels will not absorb water nor does it need additional waterproofing.

ApplicationsGenerallyusedasatilebackerboardinespeciallyhighmoisture areas, wedi offers a one-step, fast and clean installation method when compared to the installation of traditional floating walls or cement boards (both of which have to be waterproofed in wet areas). Applications include, butarenotlimitedtoshowers,steamshowers&rooms,gangshowers, floors, walls, countertops, tub decks, washstands, custom benches and seats without additional framework or curved walls in interior or exterior installations.

Wall Application in Showers and Wet Areas

The wedi Building Panel System is easily applied directly to studwallswithwediFasteners(screwsandwasherswithtabs). After the panels are secured and the seams are sealed, tiling may commence immediately. This means that a bare wall can be prepared, waterproofed and ready-to-tile in a fraction of the time required by traditional methods.

Whenappliedtothewall,wediBuildingPanelsmaybefixedperpendicular or parallel to the framing, saving time and reducing the frequency of joints. The panel can be fastened simply into place with wedi Screws or Nails and all panel joints butted tightly. The wedi fastener is set right into the joint where the washer head presses both panel edges together and allows for the flush transition. If a waterproof installation is required, all joints and fastener points should be treated with wediJointSealantorwediWaterproofSealingTape.

Alternatively, wedi sealing tape can be used instead of the wedi joint sealant and applied in modified thinset. The sealing tape provides adequate splash water protection but should not be used where standing water occurs because thinset might allow pressing water to migrate underneath the sealing tape through the thinset mortar.

In dry areas, the seams can be treated with an alkali resistant fiberglass mesh tape by wedi.

Using only a utility knife, wedi Building Panel is effortlessly cut and shaped.

Acontinuous1/2”beadofwediJoint Sealant is applied on the foam edges of a wedi® Building Panel before another panel is joined by butting tightly.

wedi’s extruded polystyrene foam core features a closed cell structure that will not allow water to penetrate through. Therefore, the product can stop water behind the tile level and protect framing and substrates against water exposure and deterioration.

wedi Building Panels on Tub Walls and Decks

Because of its waterproof nature, the wedi Building Panel is the natural choice for use in wet areas. wedi Building Panels can be applied directly to studs or over gypsum products to create a waterproof substrate for tile and also can be used on tub decks and backsplashes to quickly place tub surrounds. The material can easily be scored and shaped to provide radius surfaces on tub skirts and does not scratch tubs or fixtures during installation.

ThedimensionsofthewediBuildingPanelsmakeforquickinstallationsinstandardfivefoottubs.Laidhorizontally,thesheetwill span the full five foot length of the tub. At the head and foot of the tub, the panel is secured to the wall vertically where the three foot width provides the perfect dimension for a ready-to-tile tub surround. The wedi Building Panel may be notched for the flange of a tub to provide a plumb and even surface for tiled walls.

wedi® Steam RoomsWhenwediSystemsandBuildingPanelsareusedinsteamroomorshowerapplicationsasatilebackerboardofchoice,you’reassured superior performance in an environment providing saturated water vapor exposure in warm to hot temperature conditions. Properly installed, wedi Systems aid in eliminating the threat of water vapor transmission through walls that can cause deterioration and mold in the structure behind. wedi Systems will further add insulation to steam showers so the temperature difference (that causes increased vapor pressure) between the warm, humid inside of showers and the cold, low humidity outside will be kept at a minimum and energy is additionally saved. Temperature differentials between two separated areas cause vapor to move towards the colder side, but wedi Building Panels, a vapor retarder, stop this shift from occurring.

wedi Building Panels meet today’s industry requirements for vapor barriers in tiled steam rooms or showers. It is tested accordingtoASTME96,MethodE,andachievesapermeabilityratingof1orless,whichistherequirementforwatervapor barriers and can easily compare with common liquid or sheet applied waterproof membranes. However, wedi does not support this industry standard and requires a technically more demanding approach to vapor retarding in steam room applications, especially for commercial use.

Industry standards mistakenly describe and prescribe waterproofers as vapor retarders and vapor retarders as vapor barriers, therefore allowing many products to be used where they will be subject to practical failure.
