Turning Torso holds the distinction of being the tallest building in the Scandinavian region, topping 54 floors and a height of 190 m.Located in the seaside district of Malmo, Sweden, it houses both offices and apartments spread across nine segments of five-storey pentagons. The building is clothed in solar control glass for high-rises, thereby enjoying an optimum balance of thermal insulation and light transmission. 


Architect Santiago Calatrava has designed the structure based on his sculpture called Twisting Torso (that is shaped in the form of a twisting human being), and hence the name 'Turning Torso'. The topmost segment is twisted 90 degrees clockwise with respect to the ground floor. The office space spans 4000 sqm, while the residential area is sprawled over 13500 sqm and comprises 147 apartments. The building demanded the use of a specially designed solar control glass for high-rises, that would suit both the commercial and domestic spaces.


Saint-Gobain's Cool-Lite SKN 165 was the glass chosen for Turning Torso's building facade. It blocks up to 67% of solar heat by reflecting it to the outside and balances the advantages of a high performance glass with that of neutral appearance. SGG Cool-Lite SKN 165 is perfectly suited as a solar control glass for high-rises since it can be used for residential and commercial buildings alike, either for façades or overhead glazing.

Due to the unique properties of the coatings, SGG Cool-Lite ST is well-suited to applications requiring annealed and toughened or heat-strengthened glass. Its high light transmittance of 60%, low g-value of 0.33, excellent thermal insulation with U-value of 1.0W/m2K and high degree of neutrality both in transmission and exterior reflection, were ideal factors for use in the Turning Torso facades.


The high level of light transmittance, coupled with low solar factor, makes SGG Cool-Lite SKN 165 the perfect choice as a solar control glass for high-rises. Its use in the Turning Torso is standing proof that it is among the most highly preferred glasses in its class.
