Z-towers

Project details:

Z-Towers project has outstanding features of triple glazed insulated glass units with gradient silk printing on outer pane and high selective coating HSSN62/34 on middle pane. The glass units of almost 60mm thickness and weight up to 1 ton per unit and extra large dimensions of 2.5m*4.1m.

This is one of the first and biggest 30-storey twin tower high-rise residential complex in Latvia and in Europe. The towers are close to one another and are joined by a podium in the base area.

The design of the facades and the exterior design of the Z-Towers was done by world-famous architect Helmut Jahn.


Project description:

The composition of glazing is sophisticated due to a 400mm step to one vertical side that was used to create a facetted façade. The stepped edge of one insulated glass unit overlaps with next pane close to it and creates an effect of scales. The connecting bridge has a glass floor IGU’s with anti-slip silk-printed pattern.

In order to recommend to the Client the optimal construction of insulated glass unit, Glassbel R&D Department made calculations taking into account wind loads and climate stresses using a special glass engineering software, MEPLA. Due to the complicated stepped shape of the glass, a bespoke mathematical model for calculations was developed specifically for this project.

The Z-Towers complex is a combination of two absolutely incompatible things. On the one hand, apartament owners can enjoy a view over historical centre of Riga, but on another hand  - comfort and quiet life in the countryside.
