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.

Optimo™ Straps

Optimo Strap

Bradford Optimo Straps are designed as simple friction fits for standard joist spacing's. For odd sized or uneven joist spacing's, or for extra security around plumbing and other obstructions, Optimo Straps assist holding underfloor insulation in place when installing in existing homes.

Once the batts are in place fix Optimo aluminium straps to the underside of the floor joists every 500mm using a galvanised screw or nail. Optimo straps typically come in packs of 250 straps which is enough to cover an area of 53m2 when 415 batts are used and 70m2 for 565mm batts.

Optimo™ Stayfast

Optimo Stayfast

Optimo StayFast brackets make installing Optimo Underfloor batts in existing homes easy, even in cramped conditions. Optimo straps are great, but it can be difficult to hammer or drill them into place when underfloor access is constrained or when floor joists are made from hardwood or steel.

With a convenient adhesive strip, Optimo StayFast angled brackets easily stick to any floor joist and hold batts securely in place from below.

For a new build where installation occurs from above, Bradford recommends Optimo saddles be used as a quick, efficient solution.
