Because your channel will stay stagnent when you talk nonsense. How many court cases have you had to date using foil back pir in a warm roof ? Be honest !!

What is your option on what most roofing manufactures are saying the top osb3/ply should not be used and the roofing product fixed directly onto the insulation. Also the correct flat roof insulation is not foiled back if adhering or torching on the top cover. It must be fleece backed such as the kingspan Thermaroof TR26 or TR27. Full detailed descriptions of the technical reasons I can quote from them. But the short of it is that the top cannot absorb or disperse the heat and is subject to below-ambient low temperatures. So subjects the material to moisture vapour cycles which repeatedly condenses and evaporates on its surface, so in time the top deck will rot and compromise the performance of the system.

If you just seal the top of the pir and you have some air leakage the warm air will condense between the insulation and potentially rot out the plywood/osb underneath, similar to SIPS. The vapour/air barrier being installed beneath the insulation (the warm side) is best practice and reduces the possibility of air leakage entering the insulation to begin with

Hi ComeWhatThey Thanks for watching. We agree, that is one way of constructing a warm roof however there are also benefits to our chosen method. A lot of EPDM systems aren't recommended to be bonded directly to tissue faced insulation therefore the extra layer of OSB is needed. This also means the foil backed insulation is fine as we did not adhere the waterproofing membrane to this. Another benefit of the top deck is that it is more hard wearing providing a nice solid base. If the house roof ever needs to be accessed via the flat roof, there is now a nice solid base for any ladders or foot traffic. This would not be possible if we'd adhered directly to tissue faced insulation. The benefit of thermally broken fixings in comparison to those we used is minimal in terms of how they impact the U-value of the roof.
@ComeWhatThey
Жыл бұрын
@@Roofscout Thermal fixings aren't to improve the u value overall, they're to reduce cold bridging. And the issue with foil isn't just poor adhesion, it's acting as a vapour barrier on the wrong (cold) side of the roof, further helping your upper deck to rot over time. You can often get away with it but there's really no reason to have an upper deck in most cases, it's fine for limited access without one and it's just added expense for the customer.

Hi criollitoification If there is moisture within the roof build up and you add a waterproofing membrane of any kind before the whole build up is completely dry the trapped moisture can lead to an array of issues such as bubbling in the waterproofing membrane. I would ensure all Timber is completely dry before installing the remaining components. The marine ply may not be a major issue for the lower deck but many GRP/Fibreglass manufacturers recommend using osb3 T&G boards nowadays as the GRP is less likely to fail on the board joints with T&G boards and GRP adheres well to OSB. If you have no experience using a Fibreglass system I would try to avoid it in all honesty as the detailing work can be tricky and if not done correctly it will need to be ripped up and the boards will need replacing making any errors quite costly. You could try suggesting/using EPDM as an alternative. As a system a rubber roof is a lot more forgiving than Fibreglass as there is no working time (once catalysed GRP must be installed before it goes hard). We have plenty of videos on this system that you may find useful. If the client is adamant that they want a Fibreglass roof, our best advice would be to contact an experienced professional. I hope this helps and thanks for watching our videos!

Hi tinkletoesrus A warm deck flat roof refers to a construction method where the insulation is installed on top of the roof deck, creating a warm barrier. This means that the deck and insulation are kept warm, preventing the formation of condensation and potential damage. On the other hand, a cold deck flat roof has insulation placed between or below the roof joists, allowing the deck to be colder. In this setup, condensation can occur on the underside of the deck if proper ventilation is not provided. In summary, the key difference lies in the placement of insulation. Warm decks keep the deck and insulation warm, while cold decks allow the deck to be colder, potentially leading to condensation issues. The choice between the two depends on factors like climate, building regulations, and specific requirements. 🏠❄️🌡️

Hi Martin We hope you're well. We're sorry to hear you don't approve of our installation but this roof complies with Building Regulations and was passed off by Building Control. We understand every Roofer may have their own way of doing things and their own personal preferences but as mentioned this roof is up to spec. Thanks for watching again.
