Exceptional housing construction, comes with custom solutions by heroal
Located in the popular mixed residential and commercial Pankrac district, south of Prague’s historical centre, the V-Tower’s construction will be completed in 2017. Offering 120 apartments on 30 floors, the 104-metre-high residential complex already counts among the most select high-rises in the Czech Republic. The neighbourhood’s popularity is not only due to the surrounding parks and green spaces, but also its excellent transport connections: recreational facilities, shopping and both national and international schools are in close proximity. The views from the apartments, accentuated by full-height window and lifting-sliding elements, manufactured by heroal and fabricated by Sipral, are indeed the building’s most exceptional feature. The direct views over the city’s striking old city, Prague Castle and the Vltava river are just a few examples.
A building layout for an extraordinary living experience
The V-Tower’s construction area was limited by the surrounding residential and commercial buildings, thus leaving only a relatively small area available for the new building. The Radan Hubička Architectural Studio made optimum use of this limited space; the building splits into two separate towers after about a third of its height, so that plenty of space remains available for the numerous residential units. Additionally, the building’s resulting V-form gives it an extraordinary urban architectural character. The design’s underlying idea is the upwardly open letter V. It stands symbolically for openness, optimism, fortune and peace.
An exclusive building shell – thanks to heroal “made in Germany” quality
In order to underline the symbolism of “V”, particular emphasis was given to transparency. This goal was achieved, using over 1,700 sophisticated, production-optimised heroal elements from the heroal S 77 SL lifting-sliding system and the heroal W 72 window system. Since numerous custom-made units were required, due to both form and dimensions, and stringent demands for quality, design and technical detail had to be adhered to, the Sipral a.s. metalworking company made a conscious choice for heroal as a system supplier: “Not every manufacturer in the segment has the capacity to reliably realise such complicated projects, or to satisfy our stringent requirements. For this reason, we made a deliberate choice for the innovative family-owned heroal company, which provides outstanding “made in Germany” quality,” says Leopold Bares, Chairman at the Czech company Sipral a. s. According to him, heroal is the sole manufacturer in the sector to have its own, in-house, state-of-the-art bending and folding service. Additionally, heroal’s in-house, highly weather resistant surface coating ensures long-term, top-quality colour stability, gloss retention and durability against weathering. Particular attention was paid to technical aspects - given the unusual design and the building’s height, construction had to achieve specified wind load resistance rating class C3 and water tightness 8A. Windows and lifting-sliding elements were also required to achieve a noise insulation rating of up to 39 dB, thermal insulation of 1.5 W/m²K, and class 4 air permeability. This posed no problem for heroal – the heroal W 72 and heroal S 77 SL systems exceed these requirements.
