High spec windows and doors are a major expense for self-builders, so understanding the airtightness issues relating to windows and doors is important. I’ll be available on Mon 17 February between 4 & 5pm for Q&A on air tightness issues relating to doors and windows. Contact me now to join me on Zoom. If you have air tightness issues with doors or windows that have already been fitted, contact me now to discuss how I can help you.
