In PONSICO s.c.p. since 1988 we worked with the manufacturer of aluminium profiles and accessories ALUGOM and its representative in Catalonia ALUNORD. Within the series of slides that provider, find the premium SILVER 65 RPT range, with results in nothing less than remarkable trials, surpassed only by the ALU GOS- S and MATRA 135 RPT series of the same manufacturer. It has a frame width of 65 mm and a sheet of 28×75 mm, allowing it to hold glass up to 24 mm thick, can withstand loads up to 120 kg weight per sheet. Course has thermal break (RPT), with its rods polyamide 24 mm glass fiber manufactured by Technoform Bautec, gets very low values of thermal transmittance, 2.1 w ( m2k ), results that even exceed some series of PVC and wood currently. This fact is very important since it joined Guardian Sun glass types with large air chambers or argon gas, get a very high energy and cost savings over the lifetime of the window. Another of its strengths is the sound insulation , not only because and in itself is a very strong material, but because it easily supports large weight loads to incorporate acoustic glass or bulletproof glass. On the other sections also stands well above the average. It is certainly a quality investment for material in few years be repaid, not only by the cost savings involved, but by the quality of life it provides. The era of efficient windows has come, and all without sacrificing quality finishes providing aluminum. In Ponsico s.c.p. we are really pleased to be working with materials such quality as this, because after more than 30 years working in the sector, we have lived the continuing evolution of the same, with the beginning of the most basic, to be able to draw windows as evolved how are you. See no obligation any question that may arise.
