In well-insulated homes, however, windows become a key element in energy efficiency, making triple glazing a worthwhile investment. For homes with less insulation, double glazing provides the best balance of price and performance before you need to consider other costly upgrades to walls and roofs. Glazing’s energy efficiency can also be improved by opting for low emissivity glass (aka Low-E glass).
Our expert team is here to help you select the perfect windows for your needs. Visit our showroom to experience the quality of VELFAC products, or reach out to a VELFAC distributor for guidance. Choosing between double and triple glazing depends on factors like your home’s insulation level, environmental impact, and budget.
