In PONSICO s.c.p. took since 1988 working with the manufacturer of aluminium profiles and accessories ALUGOM and its representative in Catalonia ALUNORD. Within the hinged series of that provider, found the premium range ALG 75 MAXIMA, the series of the highest quality manufacturers, and one of the best on the market, both aluminum and PVC or wood, with results in trials nothing less than outstanding. It has a frame width of 74 mm and a sheet of 81 mm, allowing you to accommodate glass up to 60 mm thick, can withstand loads up to 170 kg weight per sheet. Course has thermal break (RPT), with its rods polyamide 34 mm under and 37 mm on the sheet with fiberglass manufactured by Technoform Bautec, get one of the lowest market values in thermal transmittance, 1.3 w ( m2k ), results that outperform even the best 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. In the other sections also stands well above average, bordering on excellence. 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 like this. See no obligation any question that may arise.
