FOUNDATIONS
▪ Strip foundations
- Thermal bridge created between the slab
and the foundation
- Additional timber shuttering will be
required for both the slab and the
foundation
- The insulation must be cut to size to fit
under the slab, generating waste and
cost
- The timber shuttering must be removed
and disposed of after use.
