hmpmarketing Posted February 13, 2018 Share Posted February 13, 2018 Hey everyone, From my thread nearly a year ago, I have yet to implement my garage build. What I have decided is to convert the approved outbuilding to a garden office instead (I got big plot, so parking wont be an issue with LA). Already spoke with Case officer and he suggested a variation of a condition to replace the garage, I will keep the same external dimensions but will change the roof to perhaps a flat roof design and add a couple of windows. What I have not being able to get is a quotation for the panels. I have written about 7 companies I found on a google search, only one has actually replied, is there anyone in the forum representing a SIPs company willing to sell me stuff?

Plumbersmateuk Posted February 13, 2018 Share Posted February 13, 2018 (edited) I got in touch with http://superiorsippanels.co.uk/ They got back to me pretty quickly . Their SIP's are cementitious (I think that's the right word) so apparently you can render straight on top of them?

I agree that its would be 'possible' however it would be a really bad idea to render directly onto the outside surface of any SIPS system or timber frame wall construction, even ones faced with a cement based board. It's a much better idea in the wet climate that we have here in the UK to use a rainscreen in front of the SIPS. The rainscreen should create a ventilated cavity between the SIPS and the rainscreen layer. In British Columbia, Canada between 1985 and 2000 approx 50% of all buildings that were rendered directly onto timber framed external walls have subsequently failed. The repair costs exceed $4 billion. They subsequently altered their building codes to make rainscreen construction mandatory for timber bulidings.

PeterW Posted February 14, 2018 Share Posted February 14, 2018 Daft as it sounds .... use the cement boarded ones inside out. It’s like Fermacell and does a pretty decent finish - skim it if you want and use surface mounted electrics etc. And on the outside you can then batten and rain screen as per @Ian Link to comment Share on other sites More sharing options...

Google link: https://en.wikipedia.org/wiki/Leaky_condo_crisis Hi All, Im interested in SIP build. And have been told the MGO board type of SIP is waterproof and also structurally sound. Does anyone have any advice if MGO type SIP is the real deal even in Northern Ireland kind of wet weather? Also comparing costs - would MGO SIP be cheaper as we would just need to render on the outside? as opposed to a traditional SIP which will need another external layer of skin (i.e block work).

I'm not convinced that there is a real-life benefit in using a MGO SIP panel compared to a normal OSB faced SIP panel. I've no direct experience of MGO SIP but I assume they will still be reliant on timber in their construction for certain structural elements such as the soleplate for example and so they should still have the external render with a ventilated void between the render and the SIP panels.

Jeremy Harris Posted February 20, 2019 Share Posted February 20, 2019 A short time ago I came across some stuff on issues that had been encountered with MgO boards. The main problem seems to be chlorides coming from MgO when it gets damp, leading to corrosion of fasteners and failure of the board. A web search will quickly find some evidence that MgO boards do seem to have some issues. Take a read of this, for example: http://www.quitahumedades.com/en/blog-en/tips-and-tricks/worst-construction-scandal-in-decades . In the USA MgO is referred to as "Chinese drywall" and has a pretty dire reputation now.

You prob won't get a reply - that post is well old and having looked at the users profile they haven't logged in for a long time. There are loads of SIPs companies out there if you are after a quote - just send them your plans and they will likely send you a price. Likewise there are loads of TF companies which will do the same. Is it specifically SIP you are after? Link to comment Share on other sites More sharing options...

Polish Builder Posted November 15, 2021 Share Posted November 15, 2021 I found them very usefull. Hovewer they don't offer yet "off shelf products". You need to request a quote. Within 30 min I had a nice deal. They could not deliver 8x4 boards outside M25 but London was not an issue for them. https://insulationgo.co.uk/sip-bonded-to-eps70-plydeck-plywood-pir-sandwitched-panels-sip-sandwitch-panel-eps70-pir-london-online-uk-xtratherm-kingspan-recticel-109mm-59mm-106mm-56mm-24mm-21mm-99mm-89mm-structural-insulated-panels-plylock-2400-x-1200-ply-osb-deck/ Link to comment Share on other sites More sharing options...
