EcoTherm 60mm vs 80mm: What Perth Buyers Should Compare First

EcoTherm 60mm and EcoTherm 80mm are both foil-faced roofing blankets, but they suit different build-ups. If you are deciding between them in Perth, the first check is not just R-value. It is whether the roof or wall system can physically take the thicker blanket and whether the job actually benefits from the extra thermal step from 60mm to 80mm.

In simple terms, 60mm R1.3 is often the more practical all-round option where space, budget or build-up depth are tighter, while 80mm R1.8 becomes the stronger comparison when the roof system can accept more thickness and the project is chasing a more serious thermal result. The wrong choice is usually the one that does not suit the roof assembly cleanly.

What These Products Are

EcoTherm 60mm R1.3 with LD Foil is a foil-faced roofing blanket supplied in 1.2m x 15m rolls with 18m2 coverage. It is described on the live product page as a versatile insulation blanket for roofs, walls and floors, with the foil layer helping as a radiant barrier alongside the bulk insulation blanket.

EcoTherm 80mm R1.8 with LD Foil uses the same 1.2m x 15m roll size and 18m2 coverage, but with more thickness and a higher stated thermal rating. The live page also notes that this product is made to order and needs at least 24 hours notice, which matters if the job timing is tight.

When EcoTherm 60mm Makes More Sense

  • the roof or wall build-up has less room for blanket thickness
  • you want a foil-faced blanket step up from 50mm without moving to the thickest option on the site
  • the project is a practical shed, workshop or metal-roof job where fit and install simplicity matter
  • budget and depth constraints matter as much as thermal improvement

For many Perth shed and metal-roof projects, 60mm is the cleaner middle ground. It gives a useful jump over 50mm without creating the same clearance and build-up questions as 80mm.

When EcoTherm 80mm Makes More Sense

  • the roof assembly can comfortably take the extra blanket thickness
  • the project is aiming for a stronger thermal result from the foil-faced blanket layer
  • the building will be used more often, cooled more often, or held to a higher comfort standard
  • the lead time works for a made-to-order product with at least 24 hours notice

80mm is usually the better fit when the job has the room for it and the goal is more than a basic improvement. That often applies to higher-spec sheds, more serious workshop fit-outs, and metal-roofed spaces where heat control matters more day to day.

When Neither Choice Should Be Forced

Neither blanket should be forced into a build-up that cannot accept the thickness properly. If the roof detail, purlin arrangement, lining system or service clearance does not suit the blanket depth, the smarter move is to step back and recheck the assembly rather than assume more thickness is always better.

It is also worth pausing if the real project needs a different insulation format altogether, such as a thermal break layer or a cavity batt system. Roof blanket is not the answer to every metal-roof or wall job simply because it includes foil.

Key Buying Checks Before You Order

  • Measure the roof or wall build-up so you know whether 60mm or 80mm fits properly.
  • Check whether the project really benefits from the R1.8 step or whether R1.3 already suits the job.
  • Confirm the quantity from the 18m2 roll coverage before ordering.
  • Allow for the 24-hour notice noted on the live 80mm product page if timing is tight.
  • Make sure the blanket choice suits the wider roof system, lining detail and installation method.

How They Compare With Related Options On The Site

If you are not sure whether 60mm is enough, compare it with the thicker 80mm option. If you are stepping down for a tighter build-up, the EcoTherm 50mm R1.1 page shows the lighter-profile alternative in the same family.

If the real question is whether roof blanket is the right product type at all, the site's roof blanket insulation Perth guide is the best next article to read. That helps separate blanket jobs from projects that may be better served by products such as ThermalBreak 7 or other roof and shed insulation paths.

For broader product browsing, the roof insulation collection and shed insulation collection are useful once you know whether the job wants a foil-faced blanket or a different insulation setup.

Common Mistakes Buyers Make

  • ordering the thicker blanket without checking whether the build-up has the room
  • treating roof blanket like a simple R-value race instead of a fit-and-assembly decision
  • forgetting that the 80mm product is made to order and may need planning ahead
  • ignoring whether a thinner 50mm or 60mm blanket would already suit the job properly

The most expensive mistake is ordering a thickness that does not fit the roof system cleanly. Once that happens, the higher R-value stops being the main issue.

Conclusion

If the job needs a practical foil-faced blanket and the build-up is tighter, EcoTherm 60mm is often the better fit. If the roof system has the room and the project is chasing a stronger thermal result, EcoTherm 80mm is usually the more suitable step up.

Check the roof build-up first, then compare lead time and thermal target. The live EcoTherm 60mm product page and EcoTherm 80mm product page are the right next step before ordering.
