About Us

leading providers of aluminium joinery

The Company

Window Innovation was formed by Christian Frunt and Stu Hammar with a combined aluminium window industry knowledge of over 25 years and a combined building experience of over 60 years.

They both saw a gap in the market place where good old fashion service and reliability was missing. This service is the cornerstone of their business and is one of their “core values”

These two are passionate about their industry and will go the extra mile for their clients to make sure the finished product is what the homeowner is expecting.


The Team



Christian Frunt

Christian loves the building process, so much so he has built and sold the family home 10 times. Originally an engineer he is used to working with fine tolerances and expects and demands quality windows and doors. We must “exceed expectations” then the customer will be happy to refer their friends and family



Stu Hammar

Stu has a wealth of knowledge in the aluminium industry coming from a large Christchurch aluminium joinery company where he oversaw its growth after the Canterbury earthquakes as their General Manager. When the rebuild was in full swing, building companies couldn’t afford any delays on their houses and his guiding principle is “on time, every time”. Do this right and we will always have satisfied customers



Rachel Downie

Rachel started her career in customer service before taking on the challenge and learning her trade in window estimating using specific software for pricing aluminium doors and windows. Rachel knows the pitfalls of the building process and is very focused on customer service at the front end knowing “the team makes the difference”.  She thrives on being customer focused and believes that the customers wants and needs are very important.



Murray “Muzz” Toms

Muzz lives and breathes Aluminium joinery with over 30 years’ experience building windows and doors. He leads a talented team of fabricators on the factory floor and nothing leaves the factory without him running his eye over the finished product and giving his tick of approval. “Do what’s right” and our builders and clients will always be happy.
