Optimo Underfloor Insulation

Bradford Optimo™ is the ultimate in underfloor insulation for suspended timber floors, keeping homes warmer and reducing energy costs through winter.

Most Australian homes have ceiling insulation and new homes now also include wall insulation which is installed at the time of construction. However, for homes with suspended floors, it is one element of the envelope that may not be insulated and this can contribute to as much as 20% of heat loss in winter. Bradford's Optimo Underfloor insulation is the solution, allowing you to address this neglected area and maximise your home's comfort and energy efficiency.

A polished timber floor looks warm and inviting – but looks can be deceiving. Without insulation, your flooring material is the only thing between you and the elements. Heat can be lost and draughts can enter through the floorboards making your home cold and uncomfortable. Bradford Optimo provides a barrier to reduce heat loss and cold draughts entering through gaps in the flooring.

Choosing Optimo

Which Optimo product is right for me?

A joist is a length of timber or steel that runs parallel to the wall and supports the structure of your home.

Step 1: Measure width between joists.

Get under your floor and measure the distance between joists, measuring from the middle of each joist. The widths will most likely equal one of two options; 450mm or 600mm.

The appropriate batt sizes for the above joist spaces are as follows;

  • 450mm joist = 415mm batt
  • 600mm joist = 565mm batt

Note: for joist spacings between 450mm and 600mm, then a 565mm Optimo batt should be used and cut to suit. In all cases, the insulation should be trimmed so that its 5mm MORE than the space of the opening to allow for a snug fit. You should ensure there are no gaps between the insulation and the joists or abutting edges of insulation. If the insulation is too loose, you can trim a piece from the edge of another batt and use this as a packer.

Step 2: Measure joist height.

Determine your R-value by measuring your joist height. The depths will equal one of two options; 75mm or 90mm.

What’s your R-Value?

If you have the option of either R2.1 or R2.5 and you live in a temperate area, then R2.1 is suitable, however, if you reside in a cold or harsher environment, then R2.5 is highly recommended.
