Value Poly | Ceiling Insulation | How To

Don't let your expensive heating and cooling go to waste. Value Poly insulation has a range of R-values from R2.5 to R7.0, so you can customise your insulation solution and make sure your home stays at the perfect temperature year-round. No protective clothing required, no on-going costs,corrosion or maintenance.

Safety Notes:

  • Check the switchboard for power and light safety switches, before entering the roof.
  • Be aware of any exposed electrical junctions you find in the roof.
  • Never lay batts over electrical wiring. If there is loose wiring the batts should be fitted under the wiring.
  • To fit insulation over your downlights, they MUST have IC4 rating showing on each downlight.
  • If your down lights are not rated IC4 you MUST ALLOW a non-insulated radius of 200mm around the down light. 

What you will need:

  • Ladder (commercial or industrial grade)
  • Knife/blade
  • Drop sheet to protect carpet
  • Flashlight/headlamp
  • Face protection/mask to reduce dust inhalation
  • Clothes you don't mind getting dirty
  • Gloves
  • Safety glasses
  • Push stick [Learn More] to fit your insulation all the way into the far corners.

Pro Tips:

  • Avoid laying batts in summer, when roof space becomes dangerously hot. If the roof space is hot, limit your time to a maximum of 10 minutes at a time.
  • Early mornings are more suitable if you want to install roof insulation in hot weather.
  • Get someone to help you load material through the manhole.
  • Load all batts you can before you start work, to minimise ladder use.
  • Insulate the manhole cover by measuring, tearing to size, and then glueing.
  • Level any existing loose fill, before laying polyester insulation batts on top.
  • Tear sections of insulation batts to fill gaps in the existing insulation before you start laying the top up layer..
  • Value Poly batts are easy to tear in one direction, and tough as boots in the other. In the vast majority of cases, they can be torn to fit any space.
  • If you really need to cut in the ‘indestructible’ direction, use a long snap-blade knife, press hard and cut down several times.
