High Performance Insulation Solutions


The preferred premium insulation system for every use.


BIBS is a premium insulation that fits any design configuration of home or commercial building projects. It installs cleanly and completely fills the wall cavity with a consistent density of insulation that lasts for the life of a building. Unlike other insulation systems, the BIBS system creates the perfect fit to better control sound and reduce air infiltration.


Spray Foam seals out draughts and insulates in one.


Spray foam insulation is the most advanced insulation and air sealant. It is used world wide to insulate buildings and seal cracks and gaps, making the building more energy efficient and comfortable. SPF is a fantastic option for high performance new builds looking to utilise a warm roof design with insulation applied at the roof rather than ceiling level.

The design stage is the best time to prepare your home for high performance insulation as some systems have particular building requirements.

Andy, Kaila and Ian were all more than happy to help and provide advice. Kaila organised Andy to visit my home and assess our needs, this happened very quickly and a quote was provided the same day. Delivery of the product was arranged and Ian arrived when stated, was polite and helpful in placing the materials where we requested. Overall 5 star service from all staff that I dealt with, would highly recommend this company.

We had ceiling and wall insulation installed, as well as a draughts-stopper over the bathroom fan.Because of the nature of the job, I had some requests that would not come up very often and were not that easy to work around. I found not only did Alexander Watson take careful note of my needs, it was also very flexible as the date of parts of the installation had to be changed (they depended on other jobs having been done).I would think that builders would find their competent staff and flexibility a huge benefit, as they would deal with a lot more moving parts some of which may be delayed than we did on our more simple insulation upgrade albeit a bit different from the norm.

The Watson team did an incredible job in spray foaming the shipping container, which is our temporary home. They went the famous “extra mile” to get the job done under difficult circumstances. Thanks heaps, for that! I can really recommend Watson and will use them again for my next insulation project.

Huge thanks to the team at Alexander Watson for insulating our ceiling (vacuum and re-lay) and for carrying out additional electrical work. Especially, thanks to Ash for answering our countless questions, to Jack and the install team for a fantastic job, and to Chris and Wally for all their help post-install. The service and communication of the whole team was excellent and we're really impressed with the difference their work has made to the comfort of our house. I would not hesitate to engage Alexander Watson again - happy to highly recommend this company.

Excellent service from beginning to end. Workers appeared on time and conducted their jobs in a timely manner. Work was finished within 3 weeks of the quote. Everything was carefully explained so there were no nasty surprises. Highly recommend this company for underfloor insulation. We are already starting to see a difference, with the house experiencing only a 2-degree Celsius change throughout the day.

Insulation FAQ’s

How do I choose ceiling insulation?2024-02-16T13:52:51+00:00
