What’s the best glass specification for achieving a high Window Energy Rating (WER)?

For a high double glazing energy rating, trade buyers should opt for Low-E glass with argon-filled cavities and warm edge spacers. These features boost the double glazing energy rating by reducing heat loss and increasing thermal insulation. To meet modern efficiency standards, always check that your supplier provides a high double glazing energy rating in their sealed units.
