Double glazed period sash windows
May 27, 2015 
Sashes made from hardwood with Low Emissivity (Low E) glass combined with warm edge spacer bar technology and the air gap between the double glazed units filled with inert gas- Argon or Krypton all help make for an extremely energy efficient window with U values of 1.6 or less. Combine this with our draught proofing system and you will feel snug in the depths of winter. Don’t forget this technology also helps in the summer. Your windows won’t act like a greenhouse in the height of summer.
So in summary your home stays warm in winter and cooler in summer.
