Toplite Foundation is produced specifically for use below DPC in solid walls. It replaces the inner and outer leaf, wall ties and concrete cavity fill associated with traditional construction methods.
 
Toplite Foundation blocks deliver excellent thermal performance as the blocks help to achieve lower U-values in ground floors they also lower the heat loss from thermal bridging and give better ?psi? values in energy calculations.
