We nominate a U value of 1.4 in Lighbridge as a general to optimise Natural light and a healthy compatible home. This glass offers superior insulation by limiting the transfer of hot and cold air; making your home cooler in summer and warmer in winter. It also allows your home to have more natural light and vaster views.Double and triple glazed windows and doors
Double or triple glazed glass has become essential for the energy-conscious Australian homeowner. Designed to reduce your reliance on heating and cooling systems and slash your energy bills, double or triple glazed windows and doors have two or three panes of glass, depending on the design, separated by a pocket of inert gas. This helps to reduce thermal transfer, keeping your home cool in summer and warm in winter.

uPVC windows and door frames are made from unplasticised polyvinyl chloride, which is more durable, moisture, weather and pest resistant and long-lasting than alternatives like wood.
