Double Glazing

Double Glazing Components / Insulated Glass Spacers Sivlite Desiccant Sivlite Desiccant is a high-performance molecular sieve 3A with the capacity to adsorb moisture or organics residing within an insulated glass unit. The desiccant maintains a transparent, moisture-free double glazed unit even at extremely low outside temperatures. Usage In both air and gas-filled double glazed units, the legs of rigid, tube spacer frames are filled with an adsorbent such as molecular sieve. A spacer frame is typically filled with desiccant in two to four of its legs with automatic or manual dispensing equipment. Features • Prevents condensation of inside vapour and prolongs life span of IG windows • Important IG component which virtually eliminates window distortion • Low dust levels thereby increasing the effectiveness of the dessicant • Regularly tested in-house to ensure customers are supplied the best product • Approved by leading independent test laboratory and meets requirements of both European and American standards Specifications Item Unit Target Bulk density g/ml ≥ 0.68 Size ratio up to grade % ≥ 98.0 Water adsorption capacity % (RH 60%, 25 o C) ≥ 18.0 Delta “T” value o C (10g MS-3A/10ml H 2 O) ≥ 35 Nitrogen adsorption ml/g (250ml MS-3A, 70 o , 4hs) ≤ 0.5 Dew point o C ≤ -60 o Dust drops ppm ≤ 50 Ignition loss % (950 o C) ≤ 2 Bead Sizes: 0.5-0.9mm and 1.0-1.5mm Packaging: 25kg boxes 090 Product Catalogue For Glass Processors & IG Manufacturers

Double Glazing Components / Insulated Glass Spacers Warm Edge Excellence The insulating glass market changed forever when what is now Quanex Building Products introduced the first flexible, non-metal-based spacer technology to the insulated glass industry in 1979. The concept of reducing thermal conductivity at the edge seal for improved thermal performance was revolutionary. So much so that it inspired further innovations, including the introduction of Super Spacer®, the industry’s first structural, foam-based spacer in 1989 and, more recently, the Dura Spacer platform, which includes Duraseal® one of the first hollow, air-filled warm edge spacers on the market. What Is Warm Edge Technology? Standard double glazed units are fitted with an aluminium spacer to separate the two panes of glass. However, the conductive nature of the aluminium results in a significant loss of thermal energy. Most of the newer spacers perform better than aluminum, but still contain some metal, and this metal is highly conductive. “Warm edge” refers to the thermal conductivity of the spacer. If the spacer material is less conductive than conventional aluminium, it is called warm edge. Fitting a double glazed unit with a warm edge spacer ensures a reduced loss of thermal energy in comparison to traditional windows as well as standard IG units. What is Super Spacer? Super Spacer® is an extruded, thermoset polymer structural silicone spacer with integrally incorporated desiccants. The shape of the thermoset polymer material is set during heat curing and can’t be reshaped through reheating. Super Spacer retains its flexibility over a wide temperature range, always returns to its original cured shape and has a low compression set. The silicone formula of Super Spacer exhibits excellent resistance to ozone, sunlight, oxidation and has excellent colour stability. The No-Metal Advantage The edge of an IG unit is the most vulnerable part of the glass to heating and cooling losses, condensation and frosting. Quanex’s Super Spacer contains No-Metal and is one of the most thermally efficient IG spacers available in the market today. Email: | Web: 091
