R3.0 Ceiling Insulation
Achieve an R3.0 value
Manufacturer R-values only apply to properly installed insulation. Leaving gaps will reduce the effectiveness of the insulation, meaning it will not achieve the set R-value. Compressing the R3.0 insulation or exposing glass wool to moisture will also reduce its thermal performance.
Benefits of ceiling insulation
- Save money on energy bills
- Reduce your reliance on heating and cooling
- Reduce your carbon footprint
- Improve indoor temperature regulation
- Improve the comfort of your home
Energy report rating
When choosing what R-value is best for your home, you need to take in consideration the building design, climate, energy costs, your budget and personal preference. If a comfortable, energy efficient home is a priority then you could consider opting for a higher R-value than what is on your energy report.
R3.0 Roof and Ceiling Insulation
Generally, when insulating a ceiling, to get the best result from the insulation you’re installing, you should install the ceiling insulation after it has been plastered. This ensures all the insulation fits snugly and allows the installers to trim the insulation more accurately around lights and vents. However, if the roof slopes to a very low pitch, and that some areas are going to be very difficult, if not impossible, to insulate after plaster, there is a compromise:
Pre-load the Ceiling – Install Difficult Areas before Plaster
Simply measure up the areas you can envisage being the most difficult, and put aside the required number of bags to cover these challenging areas, making sure these are installed before the plaster is screwed into place. Preload the remainder of the bags beforehand
Areas that are often tricky to get to are the corners, and any rooms that extend beyond the regular contour of the house.
- The corners: as well as requiring lots of cutting for all the triangular joists you will see there, there are often big support beams in the ceiling making them very difficult to access.
- Extended areas: If the house is a square or rectangle, all the corners will generally have the same pitch of roof. But any rooms extending beyond the regular shape of the house, will often have a lower pitch, as well as requiring more framing, making it less accessible.
