Pro Tips:

  • Maurice, our Technical Director, explains the pros and cons of all the types of underfloor insulation and how to get the best results in the Underfloor Insulation Masterclass. It's free!
  • We recommend polyester insulation be stapled to the joists at 100mm -150mm intervals to ensure it is secure and will not sag over time
  • For the best and long lasting result, make sure the staples being used are galvanised.  We recommend T50 Staples 
  • How many staples do you need? You will need about 340 staples per pack of Value Poly Underfloor Insulation. That's about 47 staples per sq metre.
  • Use a good quality stapler. Trade Quality Stapler Rental is available if you live in Victoria


Q: Can Value Poly Underfloor Insulation be used in my Climate Zone?
A: Value Poly Polyester Underfloor Insulation can be used in climate zones 4, 6, 7, & 8. That covers all of Victoria.

Q: Is Value Poly Polyester Underfloor Insulation easy to install?
A: Installing underfloor insulation may be easy or challenging depending on your home's specific attributes. These include the height of the space beneath the floor, the spacing of the joists and any access issues.  We provide installation videos to make it super easy.

Q: What staples do I need and how many will I need? 
A: T50 Staples were the staples of choice of the ecoMaster installation crews and are the size used for most good staplers. You will need about 340 staples per pack of Value Poly Underfloor Insulation. That's about 47 staples per sq metre.

Q: What is different about Value Poly to other under floor insulation?
A: Good question. Valuepoly is an excellent choice for those individuals who want all the benefits of a great polyester underfloor product but at a more affordable price. When budget is a priority Value Poly is the best choice.

Q: What is the difference between Value Poly and Polymax?
A: They are similar products. They have the same R value and are made from the same base materials. 

Polymax  is made from 45% recycled plastic bottles and has a nominal loft of 140mm (there are some variations).  We recommend that you open the packs a day or two prior to installation to allow it to re-loft as the insulation has been compressed for transport (NOT vacuum packed).  Polymax is available is most States - Victoria, NSW, ACT, SA and WA.

Value Poly is made from 80% recycled plastic bottles. Value Poly may have a small amount of compression (it has NOT been vacuum packed) and may be slightly less than full loft (120mm) when first removed from the bag.Value Poly is available in Victoria only. If you are living outside of Victoria and wish to order Value Poly, please contact the team for a discussion about freight alternatives.

The length and width of underfloor insulation rolls depends upon the manufacturer - so check the Specs Tab carefully.

Q: How long will it take for my order to be delivered?
A: Currently the lead time is 1-2 days from the time of payment before your insulation can be delivered.  We may be able to deliver in a shorter time period - please ask!

Q: Can I pickup Value Poly Underfloor Insulation myself?
A: Yes. Value Poly Underfloor Insulation can be collected from our Collection Centre in Preston.  Call 1300 326 627 to make the appropriate arrangements.  To avoid disappointment, please do not arrive without confirming arrangements first.


Please note that in order to keep freight low, or to allow a pick up option, all “Made to Order” products will be bundled with one of our regular stock orders. If you need to expedite a made to order product please call our friendly team on 1300 326 627.
Where can you deliver to?
Melbourne Metro orders can be delivered for $98, but orders can be delivered to just about anywhere within Victoria. The freight costs will reflect the distance travelled. The cost will be the same regardless of whether it is one bag or a whole truck full.  So consider sharing with your neighbours to split the freight cost as it is the same cost whether there are a few bags or the truck is full.
How will my order be delivered?
We will contact you to make a mutually convenient time for your delivery. An ecoMaster driver will deliver your order to your door and help stack it where you want it.  They will even go over some of the finer points of installation if you wish. 
If you can't be home to receive your order, just let us know where you want it stacked.  
What if it is raining? 
As you have ordered polyester insulation, it won't matter if the insulation bags get wet.  It will just dry out.  Unlike other insulation types, you won't have to replace the whole order.  
Can I collect my order?
Yes - there is a Pickup option in the checkout process.

Q: What is the product warranty for Value Poly?
A: Value Poly carries a product warranty of 50 years, but can be highly effective for much longer than that. We have not yet seen a 'failed' polyester product. It is incredibly robust and is not damaged by the elements that would generally damage other types of insulation, such as water, termites or breakdown of the glues that hold glass fibres together.  

Q: What is the installation warranty for Value Poly?
A: As Value Poly is a DIY product there is no warranty on installation.  

To get the best value for your investment, please, PLEASE watch the installation videos before you proceed.  

If you have any questions, contact the ecoMaster team.  We are all ex-installers and have done this work thousands of times before.  We are here to help you.

Q: What do I do if I have a problem with this product?  
A: Refer to our Returns / Refunds page [Learn More].  Our Research and Development team will be keenly interested to learn of any product failure and will want images and samples of the product (if possible) so they can determine what the cause of failure was.

Pros & Cons

Living in a weatherboard house with timber floors. We have had the polyester underfloor insulation installed and maybe my expectations were too high. Walk around your house in bare feet- ahh no. Maybe we just don't run our heater as often and for as long as other people. On the positive- the house is quieter and when we do have the heater on the heat is more uniform and the heater is run at a lower temperature and for not as long. Let's see how it works in summer.

Underfloor insulation

About a month ago ecoMaster’s Polyester Underfloor Insulation was installed in my home which features for the most part (polished) wooden floors. It was on my list to do, given the house, from the 1960s, needed some updating and though a solid build, I considered there was too much outside air sneaking into it. Hence the idea of having the ecoMaster’s Polyester Underfloor Insulation. I liked the idea of having the insulation material stapled under the house and the thickness of the product made me feel well cocooned from the elements. Following the installation I can now confirm the wooden floors no longer feel icy under my feet probably by stopping air coming up through fissures in the wooden boards. Importantly and surprisingly, I have also noted a definite improvement in my breathing. I used to have a frequent need to clear my throat and frequently experienced a blocked nose at night for no unknown reason even though I do enjoy very good health. Coincidence? Maybe, but I doubt it as my lifestyle has had no change in the last few years. I need to emphasise that this has been my experience following the installation of ecoMaster’s Polyester Underfloor Insulation. Can I recommend it? For me it’s great. Should anyone wonder about it, I suggest speaking with ecoMaster for details and guidance.

Awesome Value, Easy Install

I bought just enough for one room as I wasn't sure a) how effective it would be and b) whether I could install it. I also hate going the floor, so I was more than a little nervous.

Safe to say we noticed the difference even when I'd only done half the room, and it was very easy to install following the instructional videos online. Like everything else I've bought from EcoMaster, it just works and is built for guys like me who don't mind a bit of DIY but are a bit hamfisted at times! Also gained a lot of confidence going under the house now, and will definitely be doing the entire house when I get the cash together!

Thanks again guys for a quality product.

Hey Benjamin,

We are absolutley thrilled to hear that you found our Value Poly underfloor insulation to be effective, easy to install and furthermore that you noticed the difference. We take pride in creating products that are user-friendly and built for DIYers like yourself.
We're happy to hear that you gained confidence in going under the house - after all it can be a somewhat daunting undertaking. We certainly appreciate that you will be considering our product for the entire house when you are ready. Thank you for choosing EcoMaster and for your support!
