Sandwich walls

Sandwich elements consist of two concrete leaves with an insulation layer in between. The external leaf is generally in architectural concrete. The internal leaf is in grey concrete and may be designed as load bearing or non-load-bearing. Load bearing means that it is supporting the floors and the structure above. Self-bearing means that it is only supporting the self-weight of the façade. 

Internal load bearing leaf is produced in variety of thickness between 100 mm and 150 mm, insulation layer starting from 50 mm and up; the external leaf is in variety of thickness between 60 mm and 80 mm.

Internal and external concrete leaves are connected via the flexible reinforcement and the load of the self-weight external leaf is transmitted to the internal load bearing leaf.

Maximum length of facades is 12 m, height – 3,8 m. For the residential buildings there is recommended to use the façade elements of maximum 7,5 m length.

Different surface finishing and colours are possible. On the architects requests there is possible to produce façade elements with various surfaces using special rubber liners in the moulds.  

 Precast concrete elements - sandwich walls - perfectly suit for the residential construction, first of all because of perfect thermal insulations. House, made of precast concrete elements, will be warm and efficient.
