The core components of PassivHaus explained

Each of these principles in their own right has benefits, but when used in harmony with each other, bring together the best results for the most energy efficient, healthy and comfortable spaces.

We believe in these principles so much that we've built our entire brand upon them. All of our products are categorized by their principle, each with their unique colour and icon, making finding and purchasing what you need a breeze.
