Doors, Windows & Fittings Things people are opting for in a typical kitchen-diner extension Advice from Graham Lindsay from Weru UK. Are bifold doors as popular as sliding ones? There is currently a big swing towards the panoramic full width patio doors versus the multi-pane bifolds which in our experience are on the decline. People now realise that the wow factor from a wide span glazing is 365 days a year whereas with the bifold it only happens when the sun is with us and we can open them up. 330+ days a year they may be closed with all the obtrusive mullions blocking the light and garden views! From a comfort perspective a good panoramic patio door will excel far beyond the best of bifolds both in terms of air tightness, thermal performance and room comfort. 34
