About BrickHarvest
An independent, English-language reference about insulating homes and reducing heat loss in Germany.
What this site covers
BrickHarvest collects clear, jargon-light explanations of how houses lose heat and what can be done about it, with a focus on the German context: the building types, the climate and the rules that apply when a home is refurbished. The three core topics are external and internal wall insulation, roof and attic insulation, and windows and glazing.
How the content is written
Articles are written in plain English and aim to describe established building practice rather than promote any particular product. Where figures depend on a specific building or product, the text points readers to the relevant official document instead of quoting numbers that may not apply to their situation. References to regulation point to the published text of the Gebäudeenergiegesetz.
