70 mm systems C70 Gold® AluStar system

C70 Gold® AluStar is a revelation for commercial contracts requiring a powder coated external finish yet with the energy efficiency of a PVCu profile. AluStar is in fact a cleverly designed aluminium cover that cloaks the exterior face of a C70 Gold® window or door, without any loss of long-term performance.

Like all of our window and door systems, C70 Gold® AluStar is packed with innovative product features. The fusion of aluminium with PVCu provides significant thermal benefits, particularly given the 5 chambered design of Kömmerling’s C70 and O70 Gold® systems.

There are also several realistic internal woodgrain foil finishes to complement the system and in all, it’s the perfect solution for the style conscious homeowner and commercial market specifier. Like all of our window and door products, our C70 Gold® AluStar systems are packed with innovative features.

There are literally hundreds of different RAL finishes to the external face of C70 Gold® AluStar, to meet the most exacting of requirements. To the inside face there are also many different foiled options from rich colours to realistic wood grains.
