Double Glazed Thermal Break Windows and Portholes

Please Check with the Wesley Marine Windows Ltd office for delivery dates as we have received a large number of orders which have extended manufacturing times

Reduces Heat Loss - Combats Condensation

The inner and outer aluminium frame extrusions are assembled using a polyamide strip. This creates a thermally broken profile which prevents heat transfer from the inner part of the profile to the outer part of the profile. With the unique Polyamide Thermalbreak™, which is both versatile and flexible, radius corners can easily be achieved enabling the production of a wide range of Narrowboat and Dutch Barge windows. Only available in Screw In Hidden Fixing section.

Customers who have fitted the New thermal Break windows are contacting us and telling us that they do work and that condensation in most cases is a thing of the past!

Both Portholes and Windows Available.
