Re: Alternative Building Material (expanded Polystyrene) by Teewhy2: 1:38pm On Aug 04, 2020 |
we have always been asked how does the standard design of 350 mm x 350mm parapet look on a storey building, so we decide to put up a recent installation of how it looks like on the building.

Re: Alternative Building Material (expanded Polystyrene) by Teewhy2: 1:42pm On Aug 04, 2020 |
Final outlook of the 350 x 350 mm standard parapet, this was done without roof beam casting, it is strong though but I prefer and encourage clients to always cast roof beam with it to make it more stronger . there is a strong bond between the polystyrene panels with concrete.

Teewhy2: Thank you for showing the external work. But it would have been also better to show us how the internal was done... by that you will climb and show us the internal work of the parapet.. how it was attached to the top wall. Thank you. Hajji M. 1 Like |

mufutau55:Sorry my Oga, I will try to take another picture of the internal works next time, the installer has left the site and as soon as I have another installation of this nature, I will update the page. |

Oga mi, some questions: 1. Is this polystyrene parapet fire resistant? 2. How is the area in the polystrene parapet joints, like in the edges reinforced? If you have Whatsapp number, can you please furnish me with it? Thanks. Hajji M. |
Re: Alternative Building Material (expanded Polystyrene) by Teewhy2: 3:29pm On Aug 06, 2020 |
mufutau55: Sir, 1)The polystyrene according to the information from the factory is fire resistance. what normally happens when subjected to fire is that it turn to molten form from my own experience. 2) The surface of normal polystyrene parapet materials comes with a fibre mesh material, which can also be seen on the ceiling pictures, this makes the surface very strong. The finishing of the two joints on roof parapet is done with polyplaster ( a special chemical for polystyrene). there are no external reinforcement introduced on the joints apart from the poly plaster adhesive. my email is frugesarenaltd@gmail.com from there we can exchange whatsapp details. thanks for the questions. 1 Share

Teewhy2: It is completely FALSE and MISLEADING to say this Polystrene EPS Parapet is Fire Ressistant, except there is another meaning to that word, without any proof Anything that can burn or is changeable by fire is NOT Fire Resistant. A fire resistant object will not burn or catch fire, when subjected to Fire or intense heat. And as the Distibutor or Seller,, l am sure it will not cost you anything to do a Video, set fire to a off-cut, small part of the EPS material and record if it burns and or gets burnt. We dont need "opinion" or what you think, we need facts because decisions of using a product when it comes to fire ressistance, affect peoples lives and should not be taken at face value. For example, what happenes if a neighbours buidling catches fire, how does the intense heat/fire affects the EPS Parapet of the next house? How is the EPS Parapet affected, when the house it is installed on, catches fire? Does it melt and fuel the fire or just remains up there unaffected? I actually simulated a small sample of the same material used in Coolers (not one moulded to the Parapet shape but same EPS material), set fire to it and it burned so much, emitting very toxic fumes tha would even kill faster than the fire. [b]So does this EPS Parapet behave same way?[/b]We need to know. From what you posted (and l dont know why we need a magnifying lense to reach such important information?), the addttives in the EPS (SE Grade) is very, very small (0.5% by weight) such that it will only stop burning "if" the fire or heat source is removed very quickly otherwise it will burn beyond recovery (Page 27) but we all know that this scenario is never or rarely presented in a house fire! It also said that the EPS-SE Grade starts melting at 100 Degrees, which is just the temperature at which water boils! Your document states that EPS SE grade IGNITES at 370 Degrees but Normal Fire burns at 800 degrees, which means it will be easily burnt by normal fire. Where then is the "Fire Ressiatant" claim coming from? What l see here is that an 0.5% quantity of a fire ressiting chemical (HBCD) is added to normal EPS, to make it this SE Grade so as to slightly reduce its affinity for fire but you have to add as much as 10% by weight of it, to have any meaningful effect on the fire ressisting ability of the product, yet only 0.5% is added to this one and you are claiming it is fire ressistant? Its all there in the page 26 and 27 of that document you posted I will like to use the product but you are hoarding information and stating 'personal opinions' as scientific fact!, which makes it very suspect. All l can say is BUYERS BEWARE. 6 Likes 1 Share |

One4me: Sir, Thank you for the observation and I don't intend to hoard any information or mislead anyone, from the document available to me which I posted to shows that doesn't burn easily when under fire and I stated that from my own experience it changes state to a molten form. The document is in PDF format and I had to snap to make post it but I will post the things under it for you to see. General Stages of a Building fire |
Re: Alternative Building Material (expanded Polystyrene) by Teewhy2: 11:51am On Aug 11, 2020 |
Also looking at the surface of the EPS for parapet it has a covering on it (poly plaster + Fibre Mesh) on the surface which doesn't burn. the polyplaster is like normal cement so if you cast a roof beam just like the attached below there is no way fire will get to it from the front and also from the back which has already prevented fire from getting to it. if used as ceiling, the surface already has POP cement used in plastering the surface this also will prevent the surface from direct contact with fire. cc One4me

Miscellaneous: sir, Sorry I missed this message, Polystyrene are used in ceiling designs just like POP. It is not destroyed by water like POP even if there is a leakage from the roof, if the leakage is not much the water will not get into the building but dry up on the ceiling. Polystyrene ceiling add an extra layer of insulation between the false ceiling and the roof of the structure. The materials needed for polystyrene ceiling includes: Polystyrene Panel:- (30 /40 mm) depending on level of Insulation. I also prefer 40 mm but majority go for 30 mm. The quantity of panels to be used also depends on the design as some design will engulp materials than the other. Binding wire: To hang the panels to the ceiling. 3" Normal Nail Concrete Nail 2" Filas (sponge) Top bond 5 kg White Cement Screeding paint Fiber mesh (To cover all Surfaces):- The advantage of using it is that it prevent the surface from damage from external puncture also it doesn't allow cracks at the panel joints. many people don't use it but it is the best it makes it more expensive as you need to screed the surface like 3ce compared to 2ce when you install without the fibre mesh.

These are some of the work in progress of polystyrene ceiling, these will show you how it is been done and for you to identify some of the materials mentioned earlier.

Re: Alternative Building Material (expanded Polystyrene) by Teewhy2: 11:26am On Aug 13, 2020 |
After covering of the surfaces with fibre mesh, even though some of the designs attracted many joints the mesh will not allow cracks at the surfaces . below are some of the pictures for work in progress in screeding the surfaces after installation of the mesh.

gungab: Sir, For Just responding, Is it possible to have the architectural drawing sent to frugesarenaltd@gmail.com so that we can make a proper estimate as we are not sure if there are recess on the building or is a perfect rectangle as this will affect the linear meter needed.

mufutau55: Sir, just attaching these pictures as promised and for other readers that might want to also see how it is attached if the client is not casting beam or how it will be attached to an existing house that needs facelift. Kindly note that the roof beam or any part of the roof (wood) member will not be sitting on the beam, the panel is just like a cover to the roofing.

People ask why polystyrene, then I asked why not Polystyrene? see below on some advantages A building framework constructed using polystyrene technology costs 30% less than traditional system. Arising from low cost foundation, fast construction method with less labour and no lintel level cast. All types of foundations are used for polystyrene buildings based on the building type, load and geological characteristics of the ground. |
