Prefab solution
The current construction method of a traditional bay window requires a lot of consultation between different parties and takes a lot of time and money. Thanks to the budget-friendly prefabricated solution of PROOFS ® -including structural frame, insulation, facade cladding and window- there is only one party involved. This greatly reduces the installation time and the total execution time.
