Modus French doors. Slim lines and even lower U-values

Thanks to a £3million investment in research and development, Modus French doors deliver industry-leading energy efficiency. With a triple-seal option providing superb thermal performance and air tightness, U-values as low as 0.7 can be achieved - exceeding Passivhaus standards.

Beautiful cost savings for you, too

The innovative design of Modus means lower glass specifications can be used to reduce reducing glazing costs, and 90% of Modus windows need no reinforcings, saving fabrication and labour time. Plus, multiple systems are no longer required to offer an equivalent range of products so the levels of stock you need to hold are reduced, too.
