95% of our underfloor installs use polyester blanket. It’s easy to install and applicable to virtually all homes. It’s also highly durable and moisture resistant.
Not very durable, not pleasant to install. PinkBatts SnugFloor range needs to be strapped whereas Earthwool have a range encompassed in a plastic sheet. We avoid installing it.
Expol polystyrene insulation is the gold-standard for homes in high wind zones where the sub-floor cavity is exposed. As it comes in rigid form it is ‘wind-wash’ resistant. Polystyrene insulation is best suited for applications where the floor joists widths are consistent. Older homes where this is not the case are an absolute nightmare to get a tidy and efficient result. We do not recommend.
Foil insulation is no longer seen as an efficient or acceptable option. Foil insulation works through reflection and requires the foil to be shiny. Over time it dulls and does tend to degrade. It needs to be removed before installing any new insulation.
We enjoy and welcome all challenges.
An average 90 sqm2 home can be completed in 4-5 hours.
Negative impact of wind (up to 25%) on insulations performance. Experienced by non-rigid materials like glasswool/fibreglass and polyester.
