Roofs
Problem/solution:
This project consisting of three six-storey housing units, dealt with the task of insulating and waterproofing the roof and its building material to meet tough weather conditions.
Why Expanded Clay:
Expanded clay lightweight aggregate is the only thermal insulation which can be reasonably fitted between pipes and ducts. On lightweight aggregate roofs, a vapour barrier and the necessary building service technology must be installed on site casted concrete slab or prefabricated concrete slabs first.
Experience:
Expanded clay lightweight aggregate was easy and quick to build. The expanded clay lightweight aggregate was lifted from the transport vehicle to the roof in a container, where two professionals installed the aggregate roof thermal insulation and concrete slab casting on a normal block of flats in two days.
