Services.

Knowing how to install and use the right products is just as important as buying the products themselves. 5Merchants also offers services that ensure your ventilation and window design and installation are done properly, your building is airtight, and your plans will actually work as they should, ticking all the right boxes.

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.
