About Optimo Underfloor Glasswool Insulation

Installing Bradford Optimo™ is like slipping on a thick pair of socks that stops the cold entering your home and keeps your toes warm. 

If you have an older home, installing ceiling insulation is a great way to improve your comfort and energy efficiency, but if your home has been built suspended off the ground, your floor could be letting you down and as electricity costs spiral upwards this can result in nasty surprises when you receive each quarterly bill.

Even where homes are well-insulated, households could still be losing as much as 15 – 20% of their heating and cooling energy use through the floor. Bradford Optimo™ is a rigid, high density insulation with excellent thermal and acoustic properties, specifically developed to increase the comfort, energy efficiency and safety of homes with suspended timber floors. Step by step instructions on every pack make installation of Bradford Optimo an easy DIY job.

Bradford Optimo™ is manufactured under ISO 9002 Quality Systems and complies with AS4859.1 “Materials for the Thermal Insulation of Buildings”. This is your assurance that it will provide the level of performance stated on the pack. Established over 75 years ago, Bradford Insulation is Australia’s most experienced domestic insulation company. This experience, combined with our world class manufacturing technology is your guarantee of quality and performance, all backed by CSR, Australia’s leading building materials company.

  1. well worth the effort

    Posted by James on 11th Jul 2018

    Took a bit of installing under the floor with only around 60-100cm clearance. The batts fitted snugly in the floor joists and cut easily to go in odd size spaces. Rooms have gone from teeth chattering cold to cool. We have a 110 sq m house, 70 sq m on suspended floorboards where the batts are, with high ceilings and only need to run a 25MJ gas heater on low for a couple hours a night.

  2. immediate difference
