Review: Effective, clean and easy - I ordered this to use as insulation in a bread oven I am constructing. I found it to be of very good quality and extremely clean and easy to use, which allowed me to complete the job quickly. Having used vermiculite before, I am confident that it will do the job.
Review: Great Multi Purpose Product - Purchased this to seal a wood burning boiler flue that passed through a cavity wall. Followed instructions mixing with small quantity of water and packed out the void between wall and flue before rendering over with mortar mix. Once I got the consistancy right it held together nicely and did the job I purchased it for admirably and has created a safe fire proof job. Quantity was far more than I needed which was a double whammy as my wife seconded the surplus and is using it to mix with potting compost for her greenhouse plants as it is great for retaining moisture. Great multi purpose product.

## Questions & Answers

**Q: This good enough to create a pizza oven dome?**
A: Good Afternoon,

Thank you for your enquiry.

Vermiculite Insulation granules are designed to be poured down either side of a multi-fuel Flexible Chimney Liner to keep the flue warm, maintain an efficient draw and reduce the build-up of condensates. It also provides the additional benefit of holding the liner rigid for cleaning.

This Vermiculite is medium grade consisting of granules sized between 5 -15mm.

If you have any further queries, please do not hesitate to contact me again.

Kindest Regards

Lyndsey

**Q: Is this suitable for a hard to reach cavity between a ceiling and roof tiles?**
A: The product is very light and can fill any cavities. However, you may require large quantities if you plan to use it instead of fiber glass for insulation. A 2m X 1m X 50cm horizontal surface required about 5 bags (500 l). It isn't the cheapest of option unless you have to use this product because of its non flammable properties.  PS not mentioned on the bag but I would recommend wearing a mask when you apply. It is very dusty.

**Q: Is this suitable for loft insulation?**
A: Yes this is suitable for loft insulation.

**Q: Anyone have any idea how many litres I would need for a tandoori oven?**
A: It rather depends on the size of your oven.  However, 100 litres is quite a lot in a volume sense so I would suggest you order one bag and see how you get on.

### ⭐⭐⭐⭐ Light insulation
*by B***E on 26 February 2018*

Used it for insulating concrete at a 5:2:1 mix of Vermiculite: Cement: Sand and found the consistency just right for the job. You may want to experiment with the mix for whatever job you are doing with it. You definitely want something to hold it together unless you are burying it as it is very light and will blow away unless contained. It is so light you can pick up a 100Ltr bag with two fingers.
