Bradford Optimo Underfloor Insulation
When you insulate under your floors – you’re going to want the best. Bradford has been Australia’s most beloved insulation company for over 80 years and their Optimo underfloor range is a true testament to that. Optimo underfloor insulation can reduce heat loss in winter by up to 20% and also provide soundproofing benefits. It’s also easy to transport and install. Take a look at our range below.
Bradford Optimo underfloor insulation is designed to tackle one of the biggest sources of heat loss in Australian homes: cold, draughty floors. Unlike traditional insulation batts used in ceilings and walls, Optimo is engineered specifically for suspended floors and subfloors, where cold air can move freely underneath your home. By creating a protective thermal barrier, Optimo helps keep warmth inside during winter and prevents cool air from escaping in summer. It’s available in practical R-values like R2.5, giving homeowners an effective and reliable way to stabilise indoor temperatures year-round.
One of the standout features of Bradford Optimo is its build quality. Bradford has been Australia’s most trusted insulation manufacturer for more than 80 years, and the Optimo range is a great example of that expertise. The batts are easy to handle. The R2.5 packs come in a convenient size (90mm x 1160mm x 415mm, covering 4.3m² per pack), and they’re designed to fit securely between underfloor joists without sagging over time. Beyond thermal performance, Optimo also helps reduce external noise entering through the subfloor and cuts down on annoying draughts that can creep up from below.
Underfloor insulation is one of those upgrades you feel straight away, especially on cold Melbourne mornings. Bradford Optimo underfloor insulation works by dramatically reducing heat transfer through suspended floors, which can otherwise let as much as 20% of your winter warmth escape. With Optimo in place, your floors stay noticeably warmer, draughts are reduced, and your heating system doesn’t have to work nearly as hard. It’s a simple improvement that delivers year-round comfort and meaningful savings on energy bills.
Beyond thermal performance, Optimo also provides acoustic benefits. Because it creates a dense, consistent layer beneath the home, it helps reduce external noise entering through the subfloor, which is handy for homes near roads, rail, or busy neighbourhoods. Customers often tell us that their homes feel instantly quieter and less “echoey” after installation. And since the batts are designed not to slump or sag, they keep performing at the same high level for decades.
Getting underfloor insulation right isn’t complicated, but it does require a product designed for the job. Bradford Optimo is made for suspended floors and comes with both install-from-above and install-from-below accessory options to suit different build types. For existing homes, installing from below is common, while new builds often use an above-floor method before the floorboards go down. At Insulation Essentials, we supply all the components required and can advise on the best method for your project.
We always remind customers that underfloor insulation should be installed snugly between joists without being compressed, as squashing the batts reduces their R-value. Secure fastening is also important, since it keeps the insulation in place long-term and ensures it won’t sag or block ventilation pathways. For safety, gloves, long sleeves and eye protection are recommended, especially when working in tight subfloor spaces. While many homeowners choose to DIY, others prefer professional installation for speed and convenience, and our team can help guide you in either direction.
