which will satisfy the standards of tomorrow. It is also the best suited for large doors for balconies and terraces. • Sliding window 60 mm and multi- sliding - theAluplast slidingwindow series with its slender design and especiallymatched reinforcements for best structural properties canbe designed according to individual requirements. Suitable forwindows and large balcony doors. • Lift-and-slidedoor-withitssmooth- runningliftingmechanism– awidth of up to 3 m, a construction depth of 70 mm and with large reinforce- ments for the highest degree of stability, it can be moved easily. Security fittings – cap head fittings guarantee superior security and intruder protection, even in a tilted position. Longevity - all mechanical parts are made from an extremely durable zinc alloy with a multi-layer coating is available in red, white and rust and fitted with an integrated anti-draft device. The safety device prevents drilling from the exterior by a steel enclosure inside the frame. The importance of the right glass choice for a window is often underes- timated. Letting light into a building is only one job a window should per- form, it should also should keep heat, cold as well as noise out and create a solid barrier for intruders. The right combination of these variables makes it necessary to step up the glass composition substan- tially from the commonly used single sheet of float glass. The Sealed Insulated Glass (SIG) unit inherently multiplies the possi- bilities by using two different sheets of glass depending on the require- ments. According to Macleod Smith there are a number of solutions avail- able including Tinted, Tempered/ Toughened and Laminated. Macleod Smith concludes that some double glazingwindowoptions are cheaper than a single sheet of float glass.

homeowners and, overall, through the reduction of imports. In other words, the new Skyward Windows division exemplifies the kind of inte- grated, coherent approach to busi- ness that is most likely to transform the South African economy by solving socio-economic issues through the agency of small and medium sized enterprises.” The new Skyward Windows fac- tory has a production capacity of 120 units/day per line. It has been designed for a minimum of five pro- duction lines. According to Skyward Windows CEO, Oliver Macleod Smith, “Our customers are highly sophisticated individuals, companies and corpo- rates who expect and deserve the ultimate service from suppliers such as ourselves. Technical equipment forms the foundation of being able to deliver on this promise, but equally important is the right team of spe- cialists and factory staff to handle the design, equipment, materials and distribution correctly, from start to finish, to ensure perfect product quality and timeous delivery on a permanent basis.” Skyward windows is a member of the Association Of Architectural Aluminium Manufacturers of South Africa ( AAAMSA) and their affiliated associations such as the South Af- rican Glass and Glazing Association (SAGGA), the Thermal Insulation Association of Southern Africa (TIA- SA). The company has successfully obtained SANS 613 certificates for their products by offering the best energy efficient doors and windows in South Africa. SANS 10400 XA is a compulsory statutory requirement governing the minimum requirements in the built environment to ensure energy

frames of external doors and win- dows and skylights) to nett floor area per storey comply with theminimum energy performance requirements; • Buildings with a fenestration area to nett floor area per storey that exceed 15% shall comply with the requirements for fenestration in accordance with SANS 204; (204 becomes mandatory in this case) • All fenestration air infiltration shall be in accordance with SANS 613. (613 is mandatory in any case) Compared to alternative window framematerials, uPVC always outper- forms aluminium and in most cases, timber as well. Steel windows are no longer a consideration as it does not comply with the SANS 613 criteria. Skyward Windows offers frame systems which start at Uf values of 2.8W/m2K and all the way down to 0.79W/m2K. Combined with the per- formance sealed insulated glass units of Ug values from 2.6W/m2K down to 0.5W/m2K and solar heat gain coeffi- cients from0.77 to 0.33. By improving the thermal performance of windows, it will significantly reduce noise pol- lution within a building. The uPVC windows special manu- facturing technique applies the decor lamination foil on the uPVC window profiles. This technique guarantees an even structure, and uniform co- lour, as well as maximum weather resistance and meets the highest requirements regarding climatic influences. Modern uPVCwindows are a clever investment in the future. There are various window profile options: • IDEAL 2000 is the most substan- tial 3 to 4-chamber window with two levels of sealing and a 60 mm construction depth. The window offers thebest possiblepriceperfor- mance ratio and perfect economic efficiency. It is the perfect window for fixed, tilt-only and tilt-and-turn casement openings. It is suitable for commercial and residential use. • IDEAL 4000 with five chambers as a standard combination, sound insulation up to 45 dB and a con- struction depth of 70 mm, offers excellent thermal insulationproper- ties –delivering a rangeof windows
