Porotherm facilitates smarter, faster construction and earlier completion

Porotherm facilitates smarter, faster construction and earlier completion. Consequently the client benefits from the building being ready sooner whilst the builder sees a quicker financial return and is able to complete more projects in a given period.

Hard costs
Porotherm wall costs are roughly equal to traditional blockwork, but with significantly faster build potential.

Soft costs
Due to the speed of construction, storey height in a day capability is possible and with 95% less in built water, significant programme benefits can arise.


Wall Speed and Cost Indicator
The indicator compares construction speeds and indicative costs for concrete blockwork and core range Porotherm blockwork.

U Value Indicator
The U value indicator allows you to imput your desired wall U value, select insualants and finishes, and will recommend the required Porotherm block thickness.
