INTERIOR WALLS 001CHAPTER 04

1. DEFINITIONVertical constructive element that is not exposed to loads; it divides two interior spaces, in proper conditions of safety and comfort.

2. TYPOLOGYAccording to their working conditions, we’ll classify interior walls in two groups:

2.1 Dry Interior WallsThose found in areas not exposed to moisture. They generally divide aisles, bedrooms and other dry areas.

2.2 Wet Interior WallsThose exposed to the temporary or permanent action of humidity, such laundry areas, bathrooms, laboratories, kitchens, etc.

3. FIELD OF APPLICATIONPLYCEM interior walls may be safelyused in residential houses, public, commercial, or institutional buildings, and any kind of new building or remodeling in urban, industrial, rural or agro-industrial areas.

For the nature of its components,PLYCEM interior walls are ideal for high traffic areas, exposed to a high risk damage.

4. DEMANDS ANDREQUIREMENTS

Interior walls are exposed to dif ferent demands that should be considered when designing and building them:

• Acoustic Insulation• Thermal Insulation• Installations• Fire Prevention• Seismic Stability• Anchoring Furniture• Finishes and Coatings• Impermeability• Openings for Doors and Windows• Maintenance

To comply with the above, it’s highly recommended that a qualified professional is in charge of designing, calculating and supervising each project.

5. COMPONENTSPLYCEM interior walls good quality and performance depend to a great extent on the quality of its components; that is why PLYCEM offers a portfolio with the necessary products to obtain a complete solution.

5.1 Supporting StructureIt constitutes the backbone of the wall and must be correctly assembled, following the recommended technique for each chosen product, according to the demands and specifications, and of the norms and building codes that apply in each country.



5.1.1Galvanized steelThis kind of material is one of the most frequent options chosen

Galvanized, laminated steel profiles, cold contoured. This kind of profiles and sections are selected depending on each project’s requirements.Geometry used for every application is of generic use, and free commercial availability:

• Joint Stud "C" type profile, used at the coupling point between two sheets.To guarantee enough support, and prevent the appearance of fissures at fixing points, it’s recommended to strictly comply with the "minimum width" recommendations.

• Intermediate Stud Its generic form is similar to the Joint support.It differs in the section’s width in contact with the sheet; used as intermediate supporting element between joint profiles.

• Track"U" type profile, used as bottom and upper fastening crossbeam in vertical profiles.

5.1.2 Wood It’s a very familiar and friendly option for builders; wood must be of very high quality and of uniform cutting, industrially treated to guarantee its dryness, resistance to wearing and insect attack.

5.2 Anchorage Screws, plastic plugs, expansion bolts, nails, anchors, and other elements constitute the most frequently used solutions for anchorage or fixing structure of walls to the primary structure of a building. It’s recommended to use elements protected against corrosion, following the manufacturer’s recommendations for a correct installation.

5.3 Sheets PLYCEM sheets that are recommended for interior walls should be selected according to the typology of use for the wall:

·Dry WallsSheets of a minimum thickness of 8 mm.·Wet WallsMoisture-proof sheets, of a minimum thickness of 11 mm.·High Traffic WallsSheets of a minimum thickness of 11 mm. Nominal commercial sizes available are:

1220 x 2440 mm. (4' x 8')1220 x 3050 mm. (4' x 10')

It's possible to find different surface finishes, their availability to be checked in every country:. Smooth: un-calibrated, calibrated. Grooved: calibrated and un-calibrated. Wooden Texture: smooth and grooved



5.4 FixingsIn all applications, a good performance depends to a great extent in adequately fixing the structures that constitute the basic support of the sheets and of properly fixing the sheets to this structure. Different factors contribute to this, like:

• Type of Structure.• Distribution and placement of the structure.• Tracing to correctly locate the screws.• Use of adequate tools.• Movement in structural system.• Expansion and contraction of sheets• Treatment of Joints.

On account of this, it's recommended to use the fixing elements designed by PLYCEM.We can group them basically in two:

5.4.1 Fixings for Assembling the Structures

• # 8x½ or 3/4 " extra flat-head, non-skidding, galvanized steel screws, High-Low screw thread, self-drilling kind fine tip (LH8-050, LH8-075). Used to assemble galvanized steel structures of a thickness up to 0.8 mm.

• #8x ½ or 3/4 " extra flat-head, non-skidding, galvanized steel screws, type "S" screw thread, self-drilling bit tip (LH8-050, LH8-075). Used to assemble galvanized steel structures of a thickness between 0.8 mm. and 1.4 mm.

5.4.2 Fixings for Installing Sheet• # 8x1-1/4" trumpet-head, galvanized steel screws, self-countersinking groove, High-Low screw thread, self-drilling fine tip (PL 8-125). Used to fix PLYCEM sheets of a thickness up to 11 mm., to a wood or galvanized structure of a thickness of less than 0.8 mm.

• # 8x1-1/4" trumpet-head, galvanized steel screws, self-countersinking groove, type S12 screw thread, with self-drilling bit tip, and flaps for expanded perforations (PH 8-125). Used for fixing PLYCEM sheets of a thickness up to 11 mm. and 14 mm to galvanized steel structures of a thickness between 0.8 and 2 mm.



5.5 Anchoring

Screws, nails, anchors and other elements are the most frequent solutions for anchorage or fixing of structures of interior walls to the main structure of a building. It's recommended to use elements protected against corrosion.

5.6 Sealants and Additives

When the finishing stage of a wall comes, it's required to treat joints between sheets, and give a final treatment to the surface; this requires use of a list of specifically designed supplementary products.

Among them are rigid or flexible chemical sealants, for finishing joints, stabilizing putties to improve the surface of sheets, adhesives to install tile and glazed tile, which are some of the special products included in this portfolio.
