As with all vessels, there are many different windows and frames to choose from for your canal boat or narrowboat. We happily tell you why it is best to opt for thermal break boat windows in your situation. When you choose for a thermal break in your boat windows, less heat can be transferred between the inside and outside of the frame. This leads to reduced condensation and heat loss. This also works the other way, so cold is also conducted slower. The same counts for noise. So, in short, the main benefit of thermal break boat windows in your canal boat or narrowboat is the year-round comfort. Thanks to the fact that condensation is reduced, you will also experience more light in your cabin than you are used to!
