Blown-In Cellulose Insulation Fills the Gaps Batts Leave Behind.

Command Star installs blown-in cellulose insulation across Ballarat homes and businesses and has done so since 1993. Every job is carried out by AQF-certified installers (RTO No. 70212), supplying and installing this product for residential, commercial, and industrial properties across Ballarat and surrounding Victoria.

Blown-in cellulose insulation is a loose-fill, recycled-paper product blown into ceiling cavities using specialized equipment. It settles into irregular gaps, corners and awkward roof angles that rigid batts can't reach, giving full and even coverage across the whole ceiling.

Loose-Fill Cellulose Reaches Corners, but Batt Insulation Cannot.

Unlike rigid batts, blown-in cellulose settles into irregular ceiling cavities, around obstructions, wiring and awkward roof angles, giving more complete coverage without gaps that leak heat.

Cellulose is made from recycled paper content, carries low embodied energy, and contains no chemical binders or formaldehyde, making it a non-toxic option for occupied Ballarat homes.

Cellulose Installation Works Around Your Existing Ceiling.

1. Onsite Assessment. An installer inspects the roof cavity, checks existing insulation condition, and confirms access points before quoting.

2. Cavity Preparation. Any degraded old insulation is removed and vacuumed where needed, and access hatches or blow-in points are set up.

3. Machine-Blown Application. Cellulose is blown through a hose directly into the ceiling cavity, filling around joists, wiring and awkward angles to an even depth.

4. Coverage Check. The installer checks depth and coverage across the full ceiling area before finishing the job, confirming the space is fully and evenly filled.

Common Questions About Blown-In Cellulose Insulation.

  • Is blown-in cellulose insulation safe for older Ballarat homes?

    Yes, it is non-toxic and free from chemical binders, making it suitable for period homes with irregular roof cavities. An onsite assessment confirms whether existing wiring or roof structure needs any consideration before installation.
  • How much ceiling coverage does cellulose insulation provide compared to batts?

    Because it is blown in as loose fill, cellulose settles into gaps, corners and around obstructions that rigid batts cannot fully cover, giving more even coverage across an entire ceiling cavity.
  • Does blown-in cellulose insulation settle or lose effectiveness over time?

    Quality cellulose is treated to resist significant settling, and Command Star checks depth and coverage during installation to account for any expected settling so performance holds over the long term.
  • Can cellulose insulation be installed in a ceiling with restricted access?

    Yes, this is one of cellulose's main advantages, as it can be blown through a small access point into cavities that are too tight or irregular for batt installation.
