Low Emissivity or “low-e” glazing has become a popular choice within the building industry over the last few years. This glass maximises a buildings’ insulation so that you stay cooler during summer and warmer in winter. At Nuline windows and doors we are strong advocates for environmentally sustainable options. This is why we recommend low-e glass to those looking to save money on heating and cooling, have lower energy requirements, all the while helping our planet.
Increasingly people are getting aware about the vital role windows can play in achieving the required energy rating of a house. Contrary to LoE-i89 or self-cleaning glass, a special low emissivity coating is applied to the internal glass (in a double-glazed unit) to maximise performance in our warmer climate. Shown on the right is the positioning of the low-e coating and the effect it has on the sunrays. The coating cuts unwanted incoming long wave radiant heat from entering the building. It also absorbs heat conducted indoors from heating units, therefore cutting energy costs.
