LithoGlas – Solid Floor Insulation

This build-up can be used to replace a standard solid floor construction using a concrete slab and PIR insulation and creates a free draining, re-useable floor structure that is completely dry and can be finished immediately.
This makes it ideal for projects where time is of the essence or where lots of timber is present that needs to be kept dry. None of the materials are wet so there is no waiting between the layers for anything to dry.
Concrete slabs and screeds take time to dry and release large quantites of moisture into a building, which can cause movement in timber and mould. Once set they cannot be adjusted, only broken up and disposed of.
The possibility of deconstruction is what reduces the long-term environmental impact of this floor specifcation. Although Foamglas uses post-consumer recycled glass, it still uses a significant amount of energy in it’s production. However, once produced, it is inert and non-toxic, durable and does not break down. As it requires no binder to hold it together it can be endlessly reused.
The ability to adjust the thickness of layers is also useful as it creates the possibility of either correcting errors or enabling adjustments in height at a later date. If a floating timber floor is used over the Lithotherm tiles, the entire floor can be disassembled and re-used elsewhere.
