<p>Artic - The standard choice in smooth surface, value for money tiles. Artic is ideally suited to a simple, basic ceiling when standard sound absorption is required. Less than half the weight of traditional ceiling tiles, Pacific is easy to carry, cut and install.</p> <p><strong>Technical data</strong><br> Sound absorption<br> Sound absorption data has been measured in accordance with ISO 354. Sound absorption data αp,αw and absorption class are calculated in accordance with ISO 11654. Noise Reduction Coefficient (NRC) is calculated in accordance with ASTM C423. For sound absorption details, click an assortment line in the table above.</p> <p><strong>Fire performance</strong><br> General<br> Rockfon ceiling tiles have a core of stone wool. Stone wool is non-combustible with a melting point of more than 1000°C. </p> <p>Reaction to fire<br> Class A1 in accordance with EN 13501-1.</p> <p><strong>Fire protection</strong><br> The fire resistant properties of stone wool ensure Rockfon ceiling tiles provide fire protection in construction. The fire protection properties of Rockfon ceilings have been tested and classified against European norm EN 13501-2 and/or national norms depending on requirements in national building codes.<br> Some sizes and edge details of Pacific can be used with various RockLink grid systems to create a 30 minutes fire protecting ceiling in accordance with BS 476 Part 21 and Part 23. They can also be used to create a 30 minutes fire protecting membrane ceiling (integrity only) in accordance with BS 476 Part 22.</p> <p><strong>Humidity resistance and dimensional stability (flexural tensile strength)</strong><br> Rockfon ceiling tiles are dimensionally stable even at humidity levels of up to 100% RH and can be installed at all temperatures ranging from 0°C to 40°C. No acclimatisation is necessary. Pacific is predominantly classified as class 1/C/0N in accordance with EN 13964. However, certain module sizes (width > 700 mm) are class 2/C/0N.</p> <p><strong>Light reflection</strong><br> White: 85% diffuse light reflection in accordance with ISO 7724-2.</p> <p><strong>Hygiene</strong><br> Stone wool has no nutritional value and therefore it provides no sustenance to harmful micro-organisms.</p> <p><strong>Cleaning</strong><br> The surface can be vacuum cleaned with a soft brush attachment.</p> <p><strong>Aftercare</strong><br> The tiles can be treated with Rockfon finishing paint, PVA water-based special paint with safety code 00-1, applied in the correct amount with an airless spray with good capacity. The surface of the tiles must be clean and dry and the existing paint surface must be firmly adhered to the tile prior to treatment. Heavily discoloured tiles should be replaced. The painting of acoustic tiles reduces the sound absorption by approximately 10%. Environment</p> <p>A representative selection of Rockfon products have been awarded the Indoor Climate Label and the Finnish Indoor Climate label (M1).<br> Pacific is recyclable.</p>
