  • Ceramic fibre board suppliers Ireland

    I am trying to source oven construction materials in Ireland. I am based in N. Ireland. Fire brick and cement appear to be easily sourced, however, ceramic insulation between the hearth and oven floor is difficult to source. I would appreciate suggestions if someone has found a supplier.

    Also is there any problem in laying two ceramic boards side by side if I can't get a single sheet of appropriate size.

    Any help appreciated.

    From all that I've read, there is a product called Foamglas (cellular glass insulation) that is available in the UK but not the US. It's by Corningware & shows up again and again in build forums based in the UK. Apparently it's a great product & not as expensive as CaSi board.

      No issues piecing together boards side by side. Avoid placing small pieces on the edge of your insulated base.

        You can also consider perlite or vermiculite/cement mix as an insulation for both under the floor and over the dome. Click image for larger version  Name:	Vcrete K values.JPG Views:	0 Size:	159.3 KB ID:	426782 It just takes more thickness to equate to high tech CaSi or ceramic blanket.

          Thanks for the replies. I'll check out the Foamglas safe in the knowledge that vermiculate / cement is always an option.

            If I go down the vermiculate / cement route, what thickness would I need to match the insulation of 100mm of ceramic fibre insulation board? Foamglas was being delivered from Belgium, 150 of product costing 185 for delivery!

              About twice the thickness of 5 to 1 p or vcrete vs CaSi board. That said, 6" p or vcrete is a good floor insulation number for most people's need.

                Thanks for that. Just waiting on a reply from a potential supplier in Belfast who may have Ceramic fibre board. If that fails I'll go down the p / v concrete route.

                  I had the same issue -you can buy ceramic blanket from Dineens in Co Laois - http://www.dineensales.com/Industria...aspx?P_CatID=7
                  They don't have boards so I ordered 50mm board from Pottery Pro UK and there was around 20 for delivery. They sell different sized boards on ebay and it was the cheapest option that I found for delivery to Dublin.
                  here's a sample of one of their listings: https://www.ebay.ie/itm/4-x-FIRE-RES...MAAOSww9VXh7Z6

                    Thanks for that I'll check it out.

                    I have found a company in Co Wicklow that sells Ceramic Fibre Board. I just want to check the compressive strength.

                    IROCO LTD.
                    Block 3, Newtown Business Park
                    Newtown Mt Kennedy, Co Wicklow, Ireland

                    Phone: +353 1 281 0960
                    Text: +353 87 225 1677
                    Fax: +353 1 281 0964

                    CLOSED Fri, Sat, Sun and holidays.

                    They have Ceramic Fibre board in sheets 1.2m x 1.0m, the thickness available is 10mm, 13mm and 20mm. I want to have a 100mm (4") thickness and would prefer 50mm thick sheets.

                      50 mm (2" for us Yanks) is min recommended floor insulation thickness. You can accomplish with one layer or two, just stagger seams. Min compressive strength should be around 75 PSI or 517 kpa at 5% compression.

                        Thanks UtahBeehiver your help is much appreciated.

                        A bit more success on local suppliers of ceraboard, however waiting to see the spec. Maximum thickness I can get will be 20mm sheets so thinking of about 80mm thickness. I note your suggestion of layering the sheets on different axis to stagger the joins.

                        I'll post the supplier details once I know it is of suitable quality.

                        Thanks again for your excellent advice

                          Hi DogShark,
                          Just about to buy some Insulation baord for my own build based in Wicklow.

                          Who have you decided to go with in the end?

                            Hi Eirebuild

                            I haven't made a decision yet.

                            My next steps are insulation and bricks and I thought sourcing bricks and cutting them over the winter might be the priority with the insulation required only when actually building. Not sure building over the winter in our climate is a sensible strategy.

                            One of the problems I have from the local suppliers is getting information about the compressive strength of the products which is another reason I decided to focus on the brick and do more research over the winter. I haven't ruled out mixing cement and Vermiculite as a base but would prefer the ceramic fibre board option as the insulation could be kept to 100mm.

                            I have narrowed the choices

                            1. IROCO LTD.

                            Good news for you as these guys are up the road from you. I emailed them, helpful folk though not sure they would have the necessary board dimensions or thickness in stock all the time.

                            I would be interested in what you find out, if suitable, and living in Brexitville, I may need to purchase before the end of the year.

                            2. Dineen

                            Based in Athy. I emailed them several times no reply so not sure if what they have is suitable. They can supply brick according to their website.

                            3. John Doyle - Belfast

                            Refractory specialist

                            http://johnjdoyle.com/domestic-whole...ge/refractory/

                            Ceramic Fibre board stocked but unsure of the compressive strength

                            4. Victas - Bristol

                            More confident that as they sell pizza oven materials that what they have is the correct spec. Problem is shipping cost.

                            5. Pottery Pro

                            eBay shop. I think the product is ok but shipping cost may be an issue.

                            https://www.ebay.co.uk/str/potteryprouk

                            Hope this helps. Keep in touch to see how you get on.
