Starting from the bottom up.

The timber frame sole plate will be installed onto the floor slab (or beam and block etc) with a dpc between it and the masonry. Select a larger than required DPC, say 300 mm and justify this to the outside, so the excess flap is on the inside of the building. Once the time comes, the dpm and dpc can be returned up the sole plate and bottom rail and mated with the VCL. this joint can be sealed with tape etc, thus creating a perfect seal between the floor and the walls.

During erection of the timber frame, a roll of 300 mm ish wide vcl or similar should be supplied to the erectors, and this should be installed between any internal wall panel and external wall so that the vcl passes behind the internal wall. This vcl flap can then be lapped and sealed to the vcl on the rest of the walls.

The vcl must NOT be continued to the underside of the ceiling. This is a common mistake. The best solution is to install a breathable air barrier (reflective breather membrane will usually do the job) during erection. Once the ground floor walls are installed, a 1000 mm wide strip of air barrier (NOT PLASTIC... it must be breathable) should be flapped over the head of the ground floor wall panel. The floors can then be installed and the air barrier lapped up the outer face of the floor and then laid over the floor deck. The First floor walls can then be installed, and the upper and lower flaps of air barrier can then be lapped with the relevant vcl as and when the time comes.

Sockets make a big difference. Either use a service zone so that the VCL is not broken, or install a timber nogging between the walls studs, install a piece of vcl, then install the socket. The flap of vcl behind the socket can then be lapped and sealed to the vcl.

Window are also VERY important. The window should be installed into the timber frame, and sealed to the timber frame with some form of sealant, like expanding foam or mastic. The vcl should be returned into the timber frame opening, taped to the window or timber frame before the wall linings are installed.

Any pipe penetrations should be taped to the vcl and well sealed.

That is about it really. Detailing and good workmanship are the key (as with most things).]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30881#Comment_30881 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30881#Comment_30881 Fri, 22 Aug 2008 15:40:09 +0100 agu https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30882#Comment_30882 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30882#Comment_30882 Fri, 22 Aug 2008 15:41:13 +0100 Paul_B

Felxible, mould resistant, decorative, fire resistant, intumescent, interior, exterior etc.

For seeling stuff like this, i would personally suggest flexible silicone type sealant! flexible means that it is less likely to crack over time.

As for tape, there are specific products out there (usually to go with a specific type of vcl) but generally the most sticky kind of tape you can find. Duct tape, parcel tape etc.. Personally i would use glass re-inforced tape. It has fibreglass strands woven into it. Its almost unbreakable and very very very sticky!

Glass tape (as i call it) and flexi silicone can be purchased from any diy store!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30886#Comment_30886 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30886#Comment_30886 Fri, 22 Aug 2008 16:23:19 +0100 Paul in Montreal
As for tapes, never ever use "duct" tape for anything. The adhesive dries out and its performance over a wide range of temperatures is awful. Aluminuium foil tape is excellent for airtight sealing. Over here, the air barrier is normally sealed with "tuck tape" - this has special adhesive that works down to around -40C and up to around 50C or higher - so it's ideal for our climate. Not sure if it's available in the UK: http://www.can-save.ca/index.php?option=com_content&task=view&id=195&Itemid=93 (see especially page 2 with a windsurfer sail held together with this tape).

As for environmentally friendly, their green credentials are that they save energy by reducing air leakage - I'm sure this far outweighs any other non-green concerns of the materials in such products.

I could not turn this into a dwg in my head. Can anyone turn that into a dwg to post on here?

when building with sips we run the underside of the ground floor panels into the 22mm chipboard decking and the joists are fixed to top hung hangers, all gaps are sealded with silicon or expanding foam.

simple ! airtightness is an integral part of the system, no extra costs in materials or labour involved.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30957#Comment_30957 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30957#Comment_30957 Sat, 23 Aug 2008 17:53:25 +0100 Timber
I have not personally ever inspected a sips building onsite, although i have conducted a number of design evaluations etc, but i would imagine that the mastic seals would shear due to movement of the panels at some point.

as for running the sip panel into the chipboard deck... tbh i am supprised you are still building timber ground floors. Most of the rest of uk abandoned them quite a while ago now!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30961#Comment_30961 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2409&Focus=30961#Comment_30961 Sat, 23 Aug 2008 18:31:58 +0100 sipman the decking goes across the joists and the sip walls
the base plate is then set out on the decking, and the next set of walls build above.

We do not build timber ground floors, we would normally build from a slab or block and beam or any standard details as per engineers requirments.

Hence an airtight build which requires minimal heating]]>
