When we think about energy-efficient homes, the focus often goes to walls, insulation, or even solar panels. But here\u2019s the thing \u2014\u00a0windows and doors play an equally critical role<\/strong>. A poorly sealed window can leak conditioned air, let in drafts, and increase energy bills. On the other hand, airtight windows create a strong barrier between indoors and outdoors, ensuring comfort and efficiency. At\u00a0GREFET<\/strong><\/a>, every aluminium window and door system is engineered to achieve high levels of air-tightness, and that makes a measurable difference in energy savings. Let’s understand the science of air-tightness in windows and why it saves energy.<\/p>\n\n\n\n

What Does Air-Tightness in Windows Really Mean?<\/strong><\/h4>\n\n\n\n

Air-tightness refers to a window\u2019s ability to prevent air leakage<\/strong> between the inside and outside of a building. The science behind it lies in the design of the frames, seals, and locking systems.<\/p>\n\n\n\n
