Now you can do your own calculation easily for your project. Please follow the steps below, and if you are happy let us know. You can send your calculation to us and we will contact you on the next working day to make sure it is all correct. After you have paid your deposit, we will organise delivery and  transport your order within 15 working days. The products need to be paid in full prior to delivery. The calculated price will include the external blocks, required mortar and transport to your site.

BLOCK TYPE & WALL INFORMATION

The Porotherm wall system is a single leaf structure. You have a choice to build without any insulation or with external insulation or using our insulated blocks. Please choose your block type from the menu down below. Extra insulation can be added in the step 5 for higher thermal performance. Please note the insulation is not including in the price!.

BLOCK SIZE
Please choose your block size. This block size will be your wall thickness. The different block sizes have different thermal performance, as you can see beside the block. If the U-value is above 0.21W/m2K you should add some external insulation below. If the U-value is 0.21W/m2K or less than you good to go. Wet plaster and render can be applied straight on the blocks.
EXTERNAL WALL INFORMATION

Please add your external wall sizes. You can read this from your plan. It is important to try to be accurate as this will be the base of your material needs. The wall height is your wall from DPC up to the roof plate level. The usual height is 2.5m but if is different you can use the closest number from the bar. For example, your wall height is 2715mm just use the 2.75m. You can add more walls to this calculation. For example if your house is a rectangle you should have 4 walls..
