Suggestion is SIPs and paint them, I am afraid of surface spread of flame, any thoughts?

Might be worth a read.

Some sip manufactures suggest additional fire protection is required, eg plasterboard.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228604#Comment_228604 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228604#Comment_228604 Fri, 14 Aug 2015 09:47:11 +0100 djh Posted By: Triassicplasterboard

Fire resistance and non-combustibility– MgO panels have been tested to BS EN 13501 – 1:2007 standards and achieved a “Class A1” accreditation.

Also much stronger than plasterboard.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228616#Comment_228616 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228616#Comment_228616 Fri, 14 Aug 2015 12:24:15 +0100 Timber
The SIP has no inherent fire resistance, so will need fire resistant linings to acheive 30 or 60 minutes fire resistance.

There is also the need to control surface spread of flame. Intumescent paints are expensive and may not work well on OSB as a sub-straight. They will also require regular re-application to maintain the reaction to fire performance.

For a large structure such as a sports hall, I would imagine it will require a substantial timber or steel frame to work and so the SIPs are likely to be more of an infill system rather than a structural system.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228621#Comment_228621 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228621#Comment_228621 Fri, 14 Aug 2015 12:46:13 +0100 tony
I am suggesting metal stud frame, insulation and .....

Someone else wants sips cost he can get em cheap (make a bit on them too no doubt)

Good comments though Timber]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228624#Comment_228624 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228624#Comment_228624 Fri, 14 Aug 2015 13:06:55 +0100 Ian1961
I'm just finishing work on a £15M new-build sports center which has a large 8 court sports hall which is completely lined internally with 2.4m x 1.2m ply panels. We've used a clear intumescent 'paint' coating to bring it up to the required Class 1. It's a 2 coat system and doesn't need regular maintenance or any re-application. We've used it in a clear semi-matt finish so that the grain of the ply is visible.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228631#Comment_228631 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228631#Comment_228631 Fri, 14 Aug 2015 14:20:31 +0100 tony
Worrying as £15m is a huge budget to work with and we don't have that.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228634#Comment_228634 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228634#Comment_228634 Fri, 14 Aug 2015 14:42:21 +0100 Ian1961
There are lots of different manufacturers who make surface applied intumescent paints suitable for upgrading internal timber finishes to Class 1 or 0 surface spread of flame. The specification will depend on what you want to achieve in terms of final appearance.

Dulux have a product called Pyroshield and Crown have one called Timonox but there are lots of different suppliers who manufacture suitable products.

There are no specific requirements for the fixings on our project for the ply wall lining as it is non-structural. The intumescent paint is a very simple system and doesn't rely on any special fixings for the wall panel it is being applied to. You do however need to be careful with any subsequent maintenance related overpainting of the panel - any paints put onto the panel in subsequent years as part of a maintenace regime would need to be compatible with the underlying class 1 or 0 paint.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228644#Comment_228644 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13594&Focus=228644#Comment_228644 Fri, 14 Aug 2015 17:40:01 +0100 tony
