I love the ultra-thin, sleek look of metal frames for our upcoming living room extension. However, a friend warned me that metal conducts heat and will make the room freezing cold in January. Are Aluminum Windows bad for home insulation, or has the technology improved
Older metal frames were notorious for terrible energy efficiency because they easily transferred exterior cold directly into the home. Fortunately, modern Aluminum Windows use advanced thermal break technology, which places a specialized insulating plastic barrier between the interior and exterior metal profiles. This barrier completely stops the thermal transfer, meaning the inside of your frame stays warm even during freezing blizzards. You can now get that slim, modern architectural aesthetic without sacrificing your monthly heating budget.
