The range
Windows and doors, configuration by configuration.
Every double glazed uPVC window and door system we supply and install across Melbourne, Victoria — what each one does, and where it works best. Every operable unit can be fitted with a colour matched flyscreen or security screen.
Profile accreditation
Northstar uses uPVC profile systems accredited under the uPVC Windows Alliance Industry Code of Practice.
The accreditation relates to profile performance and suitability for Australian conditions.
