About JMF

JMF New Zealand sets the standard for tested timber joinery. It is owned by Master Joiners, and every JMF window and door is tested to NZS 4211.

Westpine is one of JMF’s certified manufacturers. Specify JMF joinery by name on your plans and consent authorities know the system is tested and proven. JMF’s site also has an engineering calculator for wind zones and spans, and product information for building consent.
