Open Eaves

New Builder — Fri, 26 Jun 2009 13:49:33 +0000

Having chosen some exposed rafters in the Master bedroom and in the sitting room at the design stage we decided to have conventional ceilings in the other bedrooms. We did this for to go this route mainly because of the extra cost having Oak rafters throughout.

Once Welsh Oak left the first thing I did was get a Carpenter in to sort the eaves out and it soon become clear that the open eaves we wanted were not going to be easy as the Oak rafters are about one third of the thickness of the softwood rafters and to make matters worse they are are on different levels.

The Oak rafters are all exposed so the plasterboard and 110mm of insulation is fixed on top of the rafters bringing the level up to the top of the softwood rafters that is fairly straight forward, the tricky bit is that the Oak rafters are set lower than the softwood so we will have to cut 30mm out of the softwood and fix some false Oak feet which will then level everything out and allow a fascia to be fixed to hide the insulation etc.

We will then fix a soffit at the top of the of the rafter thus giving a open eave that should appear to be Oak all the way through.

Well that is the plan anyway.

Frame now complete

Welsh Oak have now completed the frame erection and have now left the site.

They have left another Welsh Oak team to complete the lead work around the windows. They have also been inserting the panels in between the exposed Oak in the external wall or the first floor. The panels are made up of pre cut OSB board with a piece of 140 mm Kingspan attached providing the insulation inside.

Externally there is a breathable membrane attached to the OSB board then a plastic lathe is stapled every 5 – 10 mm over the whole board then to finish the panel of there is a plastic render bead on the edges with a lead dressing on the lower edges making a really neat job.

These panels will finally be coved by Lime Render which has a natural colour and wont need painting.

Frame nearing completion

As the frame is nearing completion I am turning my attention to the roof.

I have already ordered the tiles from Tudor Roof Tiles and am awaiting a delivery date. We have chosen a mixture of 2 colours, 65% medium antique and the remainder the plain red as with our other buildings on the site.

I also have to arrange the roof insulation and Fermacel for the exposed Oak areas of the roof along with the necessary batons and breathable membrane, hopefully we should see the roof start to go on in the next couple of weeks.

I had John Wilde out from www.oakcleaning.co.uk yesterday for a quote to clean the Oak of the waterstains and the blue marks that occur when the Oak comes into contact with metal, I did not budget for this although I was aware it needed doing so I hope the quote is not to painfull.
