  When building or renovating a home, windows are more than just an aesthetic choice—they are your gateway to energy efficiency, comfort, and climate control. Choosing the right window for your climate zone is essential to ensure your home performs well throughout the year. At GREFET , we understand that a window system isn’t one-size-fits-all. That’s why we’ve crafted this guide to help you make a decision based on your regional climate, lifestyle, and architectural style. Why Climate-Specific Windows Matter Your home’s geographical location plays a significant role in determining the type of window system it needs. A window that works perfectly in the dry heat of Rajasthan may not be suitable for the humidity of Kerala or the cold winters of Himachal Pradesh. Different climate zones demand different features such as insulation, ventilation, solar heat gain control, and water tightness. Understanding India’s Climate Zones India has a diverse climate spectrum, broadly classified i...

  Wondering if your windows are still doing their job? Here are 7 signs it’s time to replace your old windows —before they start costing you comfort, energy, and peace of mind. Your windows might look fine at first glance, but they could be silently affecting your electricity bill, your home's temperature, and even your security. At GREFET , we’ve seen how outdated windows can drag down the performance and aesthetic of a space. If you're starting to question your current windows, these signs might confirm it’s time for a much-needed upgrade. 1. Your Power Bills Keep Increasing If your electricity bills are rising but your usage habits haven’t changed, inefficient windows might be the reason.

Over time, this can lead to significant energy loss—and higher expenses every month. 2. You Feel Drafts Even When Windows Are Shut Feeling a breez...

  When it comes to saving on electricity bills, most homeowners think of LED lights, efficient air conditioning, or solar panels. But there's one crucial element that often goes unnoticed—windows.

At GREFET , we believe that windows should not only enhance the aesthetic appeal of your space but also perform efficiently. Let’s explore how windows impact your electricity usage—and how making the right choices can lead to long-term savings. 1. Windows and Heat Gain: Why It Matters In India’s climate, especially in cities with long, hot summers, unwanted heat gain through windows is one of the top contributors to rising electricity bills. Poorly insulated windows allow solar heat to penetrate into your home, forcing your air conditioner to work overtime. This is where GREFET’s aluminum systems come into play. Equipped with thermal insulation and double-glazing co...

  At GREFET , we benchmark our aluminium window and door systems against internationally recognized testing standards — specifically those defined by ASTM (American Society for Testing and Materials) and BS (British Standards) . These tests are not optional. They are a critical part of how we ensure durability, performance, and peace of mind. In today’s evolving construction landscape, windows and doors are no longer just design elements — they are performance systems that must withstand environmental forces, contribute to energy efficiency, and guarantee occupant comfort. That’s why certification through standardized testing is essential. Let’s explore the five core tests that shape the quality of GREFET systems: 1. Air Infiltration Test (ASTM E283 / BS EN 1026) This test measures the amount of air that leaks through a closed window or door when subjected to pressure. Lower air infiltration rates mean better thermal efficiency, reduced energy costs , and superior indoor comfor...
