Subject: Complaint about the Quality of Thermal Insulation in Construction Project

Dear Thermal Insulation Company,

I am writing to express my concern about the quality of the thermal insulation in our joint construction project. We selected your company as a supplier for the thermal insulation and were initially satisfied with the agreed product specifications.

Unfortunately, since the installation began, some problems have arisen that I would like to explain in more detail. We have found that the thermal insulation has not been installed properly in some areas and has gaps. This has caused us great concern as it can lead to high heat loss and affect the energy efficiency of the building, which ultimately reflects in the energy certificate (according to EnEV). In addition, the agreed material quality was not fully adhered to, and problems with density have arisen.

We are disappointed that these problems have occurred, especially since we deliberately chose your company as an experienced supplier. We expect high quality and care from our suppliers in carrying out construction projects and would like to find a quick solution. Therefore, we would like to ask you to send your technicians and installers to inspect and repair the faulty thermal insulation.

Thank you for your support, and we look forward to hearing from you soon.

Best regards,

Builder
