Read ArticleOur Wooden Windows Blog is written by the people who build windows in Kalnciems - project managers, joinery engineers, and coating technicians who spend their days on the factory floor. Not marketing copywriters.
We started writing this blog because every week someone emails the same questions: Does triple glazing really save money? How long will timber frames last? What's the difference between ECO 68 and Premium 115? Short answers live on our product pages. The long, numbers-included, honest answers live here.
No AI-generated drafts republished as articles. No vague "studies show" claims. When we quote a number, we link the source - whether that's EU building directives, FSC, Passive House Institute, or our own 41 independent test reports. When we don't know the answer, we say so.
Have a question we haven't covered? Email [email protected] - we answer every technical enquiry within two business days, and sometimes that email becomes next week's article.
