Product Range and Finishes

The document presents the "ROVERE" and "QUERCIA" collections of wood-effect porcelain stoneware tiles, available in a broad palette of colors including Cenere, Provenzale, Sabbia, Tundra, Corda, Noce, Briccola, Decapè, Impero, Reale, Nero, Abbazia, Antico, Moka, Ciliegio, Naturale, Bianco, and Grigio. Tile sizes vary from 90x11 cm up to 150x37.5 cm, with thicknesses ranging between 6 mm and 20 mm depending on the product line. Finishes are mainly antiqued, offering a rustic, natural wood look. Color variation is categorized into V2 (moderate), V3 (high), and V4 (extreme) to guide aesthetic expectations.

Product Formats and Special Pieces

Special trims such as bullnose (battiscopa), step treads (gradone costa retta), and corner pieces (angolare costa retta) complement the main tiles, facilitating installation and finishing. These trims match the main tile colors and finishes and come in various sizes.

Installation Methods

The tiles support multiple installation techniques including raised paving on adjustable or fixed supports, dry installation on gravel, grass, or sand, and traditional installation on screed suitable for driveways. Elevated installations require specific considerations, especially for larger formats like 60x60 cm and 120x60 cm. For example, the maximum elevation for 60x60 cm tiles is 10 cm with a recommended central support (5th leg) to distribute loads. Elevations between 10 cm and 30 cm require glass fiber mesh reinforcement under 20 mm thick tiles, while elevations up to 50 cm necessitate a galvanized steel plate.

Technical Specifications and Standards

The tiles comply with European and international standards EN 14411 Annex G and ISO 13006 Annex G, classified as BIa-UGL group. Key technical parameters include:

• Water absorption approximately 0.1%
• Dimensional tolerances (length, width, linearity, orthogonality, planarity) generally within ±0.1% to ±0.6%
• Thickness tolerance of ±5%
• Modulus of rupture ≥35 N/mm²
• Resistance to chemicals, deep abrasion, stains, thermal shocks, frost, and light exposure
• Coefficient of linear thermal expansion: 6.5x10⁻⁶ °C⁻¹
• Slip resistance values are indicative and must be confirmed prior to ordering

Color Variation Classification

Color variation is classified into three categories to set expectations for natural appearance differences:

• V2: Moderate chromatic variation
• V3: High chromatic variation
• V4: Extreme chromatic variation

Recommendations and Notes

Slip resistance values are indicative and non-binding; specific requirements should be confirmed before installation. The CM2 collection is suitable for direct laying on screed, gravel, sand, and grass. Elevated installations must follow guidelines on support height, number of supports, and reinforcement with glass fiber mesh or galvanized steel plates depending on elevation and tile format. Technical support and ordering information are available from Ariostea.

Installation Guidelines for Ariostea CM2 Collection Flooring

General Suitability

All CM2 collection tile formats can be installed directly on concrete, gravel, sand, and grass surfaces.

Elevated Installation Recommendations

60x60 cm Format

• Maximum elevation height: 10 cm
• Use a central support (5th leg) to improve load distribution
• For elevations between 10 cm and 30 cm, apply glass fiber netting glued under the tile
• For elevations up to 50 cm, use a galvanized steel plate beneath the tile
• Four supports per tile suffice for elevations above 10 cm

120x60 cm and 120x30 cm Formats

• Maximum recommended elevation height: 2 cm
• Use 7 supports for 120x60 cm tiles and 6 supports for 120x30 cm tiles at this height
• For elevations between 2 cm and 10 cm, glass fiber netting is mandatory
• For elevations above 10 cm, a galvanized steel plate is required

Critical Parameters and Best Practices

• Do not exceed recommended elevation heights to maintain structural integrity
• Use central support for 60x60 cm tiles to balance load
• Incorporate glass fiber netting or galvanized steel plates as reinforcement based on elevation height
• Adjust the number of supports according to tile size and elevation for stability
