Swisspearl Avera

Swisspearl Avera is a naturally dried, through-colored fiber cement panel made with a dynamic production process that gives it a natural, authentic texture. The surface is cloudy and naturally varied, with soft transitions in tone rather than a repeated printed pattern.

A highly resistant transparent coating is the standard finish. The coating is listed as making the panels scratch resistant and protecting them from heavy soiling and graffiti. Avera is used as a rainscreen façade board and shares a technical data sheet with Vintago and Reflex. The sheet is headed AC 90 / ASTM 1185 / EN 12467.

Vintago is a naturally dried fiber cement panel with a sanded, slightly rough surface produced by polishing with coarse abrasive grit. Reflex adds a reflective coating that creates a distinctive light reflection. Avera itself is the through-colored board with the transparent coating.

The current US selection lists the AV color series, which the US delivery program gives in nine codes.

• Material: through-colored fiber cement, naturally dried.
• Surface structure: smooth and even.
• Optics: translucent and matte.
• Coating: standard HR (high-resistance) coating, which adds resistance to scratching and weathering and protection against soiling and graffiti.
• Color codes: AV 000, AV 010, AV 020, AV 030, AV 040, AV 050, AV 060, AV 070 and AV 100.
• Largo sizes: 98.43 x 49.21 in and 120.08 x 49.21 in, both 8 mm thick.

Avera is available for interior use in the Largo format. Custom options are free forms and cutting, engravings and perforations.

The Largo format of Avera carries Cradle to Cradle Certified Full Scope, Bronze level, version 4.1. The assessment of Avera covers Material Health, Product Circularity, Clean Air and Climate Protection, Water and Soil Stewardship, and Social Fairness.

• Nominal width: 46.38 in and 49.21 in.
• Nominal length: 98.82 in and 120.08 in.
• Average shipping weight: 2.54, 3.40 and 5.08 lb/ft² for the three thicknesses.

Thickness tolerance up to 0.79 in is +/- 0.024 in, +/- 0.032 in and +/- 0.047 in for 6, 8 and 12 mm. Width from 39.4 in to 63.0 in is +/-1.18 in, and length over 63.0 in is +/- 2.0 in.

• Dry density, minimum: at least 96.7 lb/ft³ (EN 12467).
• Dry density, average: 112.4 lb/ft³ (EN 12467).
• Modulus of elasticity, ambient average: 12.0 GPa.
• Flexural strength, wet average: 3669 psi; minimum 2610 psi (ASTM 1186).
• Linear variation with moisture content: 0.03 or less.
• Avera is Type A, class IV under ASTM 1186.

Color variation measured on the production line (CIELAB) is ΔE below 2.0. Color resistance to UV under Xenon arc light (ASTM G155) is ΔE below 5.0 at 3000 hours and below 5.0 at 5000 hours.

• In-use air temperature range: -40 to +80 °C.
• Mean coefficient of linear thermal expansion: 0.69 x 10-5.
• Thermal conductivity: 0.5 W/mK (ISO 8301, EN 12667).
• Frost resistance: 100 cycles at RL > 0,75 (EN 12467).
• Water absorption (24 hours at 105 °C, 24 hours in water): 14.6 percent.
• Moisture movement at 30/90 percent RH: 0.009 in/ft.

Vapor performance is 0.19 kg/m² s Pa, with a Z-value of 5.21 GPa m² s/kg, Sd of 1.01 m and μ of 651.

Fire classification under EN 13501-1 is A2-s1, d0. ASTM E84 is listed as Class A (does not ignite), and NFPA 285 and ASTM E136 at 750 °C are listed as passed. A note on the sheet says the installation principles determine the classification.

Impact resistance under EAD 090062-01-0404 is reported for the 8 mm and 12 mm boards. Hard-body impact is Category I for both thicknesses, and Category I is also listed for concealed fixation with Signa 8 Pro and for a support batten with no fixation at 300 mm centers in lower levels and high-impact areas. Under the ETB-Guideline (1985), the boards are listed as passed for balconies.

Reported under EN 15804, ISO 14040 and ISO 14044, GWP-total (A1-C4) is 16,7 kgCO₂-eq, with 0,74 biogenic and 16,5 fossil. The manufacturing facility holds ISO 9001 quality management certification, and a Declaration of Performance with CE marking is issued under Regulation (EU) No. 305/2011.
