We have built a small 2 bed house in SW London and are struggling with the final hurdle being new build warranty (Premier Guarantee) & building control sign off on our timber cladding.

We have clad the house in rough-sawn, untreated larch and originally had a product which could be spray applied to the larch that was going to meet our fire protection requirements.

What Premier Guarantee also require is a 15 year guarantee on the product, but the product we were going to use was only guaranteed for 10 years.

Building control now want us to take off the cladding and fit supalux underneath it to meet the fire protection standards but we are still left with needing to apply something to the timber that has a 15 year guarantee and 45 mins fire protection.

With hindsight we would have done things so very differently but a huge lesson there to be had.

Has anyone had the same challenge or is aware of a product that might give us what we need with the 15 year guarantee please?

Without it we may need to remove the lovely timber cladding we have and are being pushed down the route of having to clad it in some kind of cement fibre board which seems a horrible option to us.

Anny help is much appreciated.

Thank you

The data sheet indicates:-

Protection Period: Fire retardant properties will remain active for the lifetime of the substrate.

But whether that is a guarantee....]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211120#Comment_211120 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211120#Comment_211120 Mon, 13 Oct 2014 09:30:13 +0100 LondonEcoHouse
Will give them both a call and see what they offer.

It is all down to the distance to your boundary.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211132#Comment_211132 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211132#Comment_211132 Mon, 13 Oct 2014 10:52:45 +0100 Ed Davies https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211133#Comment_211133 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211133#Comment_211133 Mon, 13 Oct 2014 11:06:44 +0100 rhamdu Posted By: dicksterNo one mentioned it when my house was clad in sweet chestnut?

Lucky you. I just visited a house in Lewes where they were not allowed to use chestnut and had to use something else (red cedar IIRC). Chestnut is apparently too dense to impregnate with fire retardant. Same reason it is such good weather protection]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211142#Comment_211142 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211142#Comment_211142 Mon, 13 Oct 2014 11:58:24 +0100 Ed Davies

“Where the external wall of a building is more than 6m from the boundary, the amount of unprotected area is unlimited.”

I'm relying on that as the nearest corner of my house will be 7.8 metres from the boundary [¹]. BCO picked up on this as being a problem until I pointed out he'd taken the edge of the decrofted area of the property as the boundary rather than the whole of the land.

[¹] could easily be a lot further if I wanted it to be but shoving it up towards the edge puts it on drier ground and reduces the tiny amount of solar shading in the winter afternoons.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211154#Comment_211154 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211154#Comment_211154 Mon, 13 Oct 2014 13:51:52 +0100 PaulJ
You may find there is a cheaper board option than Superlux to achieve the required protection.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211167#Comment_211167 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12669&Focus=211167#Comment_211167 Mon, 13 Oct 2014 16:03:06 +0100 LondonEcoHouse
Yep you are right, unfortunately our property is right up against the boundary on either side due to it being a very small urban site.

Thanks PaulJ

Yes any option was looking very expensive, if at all achievable, hence the sad option coming into the picture being we have to give up our timber cladding all together.

Also, as we are trying to sell the property and the number one negative has been the cladding. It seems that the majority do not see it as beautiful as we do!

We need about 50 square metres

Thanks all

Well worth a call, the chap I spoke to was well informed and helpful.

Snyggapa, yep we tried that one but they have some regulation/requirement regarding the life expectancy of products which must be minimum 15 years, which is even more strange as they only offer a 10 year guarantee! but they wont budge.

PaulJ, thanks for that, yes will start looking at other options now too
