Expanded clay LECA products

LECA offer builders and developers an innovative solution to make significant savings across your construction project while increasing living standards and the quality of construction – introducing expanded clay products.

Savings That Add Up

No more need for multiple layers of bricks/blockwork and cavity wall insulation – you can achieve a superior result in one layer of expanded clay brick. Cut costs on labour and materials while regaining valuable square metres of land. With a quicker turnaround time on construction, you can keep pushing on with your next project(s).

Dry, Clean and Comfortable

Prevent cold bridges being introduced as expanded clay bricks can be joined using our specialist adhesive rather than concrete between bricks. Avoid creating the conditions for condensation and mould, instead set high standards for healthy living environments. (NB: Mortar can be used if preferred).

Expanded clay is an increasingly popular choice because it is the lightest ceramic aggregate on the market while having the highest thermal properties. It can withstand up to 1,250°C without comprising its structural integrity. Due to its unique properties and porous structure, expanded clay has superior resistance to frost and excellent absorption of sound waves, supressing both the transmission of moisture and noise across walls.

A further advantage is its vapour permeability which results in quick drying of the product. Without no waiting for concrete to set and walls to dry-out, expanded clay significantly cuts the speed work can progress resulting in savings on overall project costs.
