Frequently Asked Questions:

Q: What type of insulation is best for ceilings?
A: There are several different types of ceiling insulation - ranging from more temporary measures right through to very long lasting products. 

At ecoMaster we built our own heat chamber and hired a cool room so we could empirically test all types of insulation available.  ecoMaster recommends 100% polyester.  It is selected based on its exceptional quality and long-term effectiveness. We’ve returned to ceilings more than ten years after polyester batts were installed to find that they are still thick, robust and with no evidence of rodent damage.

Time and time again polyester proves to be extremely high-performance, low allergenic, and moisture and rodent resistant. Most importantly, it maintains its thickness for the lifetime of your home, which is what makes it so good at protecting your home.

Q: What R value is needed for ceiling insulation?
A: The performance of insulation is measured in terms of R Value, which stands for ‘Resistance Value’. The Building Code of Australia requires a minimum value for new homes of R3.5 in the Melbourne area and R4.3 in colder areas of Victoria (excluding plasterboard rated at R0.7).

Follow this guide to determine whether or not your home is properly protected.

Our polyester insulation batts are fitted in between your ceiling joists enabling complete coverage for optimal effectiveness.

Q: Do ceilings need to be insulated?
A: Yes!  Without effective ceiling insulation your home cannot possibly protect you from extremes of temperature.   Up to 45% of your home's heat leaves via your ceiling.  The single most effective form of home insulation you can have is ceiling insulation.  Ceiling Insulation is the most important insulation you can install in your home. Without it your home simply can’t be energy efficient.  

Ceiling insulation works by reducing the flow of heat through the ceiling of your home.  During hot summer days the temperature in the attic (the space between the ceiling and the roof) can easily be as hot as a sauna.  Ceiling insulation places a protective layer between you and the heat in your attic.  It makes it much more difficult for this heat to travel through the ceiling and into your rooms, keeping your home much cooler.

Likewise, in the winter time, the warmest air in your home rises to the ceiling.  Ceiling insulation makes it much more difficult for the heat in that warm air to pass through into the cold attic.  This means your heating stays in your home longer making your home warmer and greatly reducing your heating requirements.

And did you know that a tiny 5% gap in your ceiling insulation reduces the effectiveness of your insulation by 50%!  So not only is it important to have ceiling insulation, it is important that it is very well installed, with no gaps!

Q: How much ceiling insulation do I need?
A: Often we find that, while many homeowners agree that insulation is important and they assume that they have some level of insulation in their ceiling, we rarely meet people who know exactly how much insulation they have overhead.

As you know, heat rises. This means in the winter, an uninsulated ceiling will let your expensive heating escape up through the ceiling. No matter how much you turn up your heater, you’ll be struggling to keep warm and the only thing going up will be your bills!

In summertime, the radiant heat from outside becomes trapped in your roof space, letting the severe outdoor temperatures push down into your home. If you have an air conditioner, it will be working hard trying to cancel out this heat; costing you a fortune and not really cooling down the house at all.

The level of insulation you need to depend upon the level of cover you already have, the zone you live in, and how comfortable you wish to be. 

For the Melbourne and Sydney area the Building Code of Australia 2012 specifies a ceiling insulation cover minimum R-value of R4.6 through to R5.1 depending on the type of roof.  In colder areas R6.3 is the minimum level specified.   An important distinction needs to be made between ‘minimum’ and ‘best practice’.  

Generally in business a ‘best practice’ view is taken towards attaining the best possible results.  However, the building industry focuses on ‘minimum standards’. Invariably today’s minimum standard is tomorrow’s inadequacy.  This is because over time, minimum standards are increased and this leaves the homes that only just met minimum standards well behind. 

Q: What do I do about halogen downlights in my ceiling?
A: If your home is fitted with halogen down-lights, it is best to replace them prior to installing ceiling insulation so that the best possible ceiling coverage can be achieved.  Aside from the fire risk and draught concerns associated with down-lights, LED downlights that are IC4 (IC standing for Insulation Contact) rated can be insulated over the top.    Refer to Rule 4.5.2.3 of Australian Standard AS:NZ 3000.

Q: Can you lay insulation on top of old insulation?
A: If you have existing ceiling insulation, rest assured that it can remain in place.  You should level out any existing loose-fill insulation, or fill in any gaps in your existing batts, before topping up with our high quality product to ensure the best thermal protection for your home.

Q: Can I return insulation?
A: Returns can only be made within 30 days of purchase and will incur a 20% restocking fee.  For a successful return of insulation, the bags must not be opened.

That may take up to 14 days if it needs to be delivered to remote locations. The ecoMaster team will be in touch to let you know when your order will arrive. 

WAREHOUSE COLLECTION:

It is possible to collect your insulation order from Sydney once it has been confirmed that it is ready for collection.  You will need an appropriate vehicle / van / truck.  Insulation is not permitted to be loaded into cars.

Difficulty Rating: Intermediate

Hacks: 

Most ceilings are suitable for ecoMaster’s polyester ceiling batts to be installed, providing there is an existing man-hole providing access to the roof space.  It can even install around any heating and cooling ducts you may have in your roof space.  Cathedral ceilings and flat (skillion) roofs cannot be easily treated by DIYers because they do not provide adequate access.
