Double Glazing

Double Glazing Components / Basic Components Basic Components of an Insulated Glass Unit A standard double glazed unit (DGU) or insulated glass unit (IGU) consists of two or more panes of glass, separated along their entire perimeter by either a rigid, tube spacer or a flexible, foam spacer. The spacer frame is fixed to the glass by means of a primary sealant such as polyisobutylene (PIB). A rigid, tube spacer frame is typically filled with desiccant in two to four of its legs whilst a desiccant compound is already included in a flexible, foam spacer. The desiccant adsorbs moisture that has become trapped in the unit during manufacture as well as moisture that diffuses through the edge seal throughout the life span of the unit. A secondary sealant is applied to the back of the spacer frame to seal the unit. There is no vacuum between the two or more panes of glass, the unit cavity is filled with dry air or, to improve its thermal performance, an inert gas such as Argon. Secondary Sealant (Tremco JS562, JS442, Spectrem 2, KÖMMERLING GD116, GD677, Kodimelt IG) PIB Primary Sealant (PIB Tape, KÖMMERLING GD115) Gas Filling Low E, Annealed, Laminated or Tempered glass Desiccant (Sivlite TM Molecular Sieve 3A Desiccant) Aluminium Spacer (Profilglass® Spacer Bars) Additional components not pictured: • Breather Tubes • Georgian Bars • Corner Keys and Connectors • Integrated Blinds 086 Product Catalogue For Glass Processors & IG Manufacturers

Double Glazing Components / Insulated Glass Spacers Profilglass® Spacer Bars Profilglass® Spacer Bars are rigid, aluminium tube spacers to separate two or more panes of glass in an insulated glass unit. FG Trading is the exclusive distributor of Profilglass spacer bars across Southern Africa and has comprehensive stocks of spacers ranging in air space size. Usage Spacer frames constructed with Profilglass spacer bars can be filled with our high performance Sivlite Desiccant and applied to the glass with one of our polyisobutylene primary sealants which include PIB Tape, GD115 or JS680. FG Trading also carry in stock all accessories required to complete a double glazed unit from straight line connectors, corner keys, gas fill corner keys, adjustable corner keys, etc. as well as various secondary sealants that offer excellent adhesion to glass and aluminium. Colours Aluminium spacer bars are usually mill finish (silver). If the unit is for use in structural or frameless glazing especially with semi-transparent or clear double glass a black colour finish may be preferable from an aesthetic point of view. This will maintain edge colour consistency, eliminate contrast between a silver spacer bar and black structural silicone and ensure that any incident PIB residue is less noticeable. Packaging The spacer bars are packaged in cardboard boxes in a length of 4, 5 or 6 metres. This ensures ease of handling and the ability to buy small quantities of product if only a limited volume is required. Sizes: 6mm, 8mm, 10mm, 12mm, 16mm, 19mm and 26.5mm in a mill finish and 6mm, 10mm, 12mm and 16mm in a black colour finish. Email: | Web: 087
