Double glazing is offered as standard in a Lockwood home. Specialised sub-frames are built around Lockwood joinery to ensure that the Code-Marked building system works to lock in performance.
There are a vast range of joinery options available, including upgrades to thermally broken, timber interior and aluminium exterior and specialised glass options to suit specific conditions. Talk to the design team and your contractor to make sure that you have explored all your options.
