Your timber can be vacuum pressure treated with Protim 418 preservative to protect against water damage if required.

If your build requires single glazed sash windows we can manufacture your sash windows to your specified measurements with single glazed glass. But if you are replacing traditional wooden single glazed windows you may want to consider implementing double glazing in your replacement sash windows. Some of the benefits to double glazed sash windows are that they are more energy efficient than single glazed sash windows and they can increase the overall value of your building.
