Energy Efficiency

The WER ratings achieved range from a respectable 'C' to an impressive 'A' and will provide you with the competitive edge when selling to the end user.

The whole range benefits from a very high insulating double glazed unit consisting of 4mm soft coat Low 'E' glass and 4mm Low Iron glass with 16mm cavity, argon filled and warm edge spacer bar.

We hope this new range of windows will excite you as much as it does us. After all, Eco Sash Windows is one of just a small handful of companies to have had their timber window range tested to WER standards.

An energy efficient window saves you money as well as help preserve the environment - this is why at Eco Sash Windows we insist upon utilising only the most energy-efficient sealed units on the market. The more efficient a unit is, the less heat from within your home is lost through it and by extension, the more you as a homeowner will save on your fuel bill.
