Roofing advice required - vaulted ceiling

clutterbug_2

We have applied and been successful in getting planning for a single storey extension on the side of an existing extension. !It is roughly 2.2m x 5m and will have a 30 degree pitched roof, that will be vaulted ceilings.

The advice I need is on how the roof will be constructed. !We are looking for the inside to look like this -!http://www.greenwoodoak.co.uk/roofs_trusses/King%20post%20purlin%20roof.jpg - and are getting various companies to quote for the trusses. !

How does the actual roof go above this type of ceiling? !Do boards go ontop of the trusses and joists (apologies if this is the wrong term!) then insulation then more boarding and then the slates?

We want it well insulated but don't really know how it will work.

Thanks

The rafters will will sit above the purlins which span across a frames insulation will be be cut inbetween the rafters and fixed to the underside and then clad with plasterboard so all you see is as your picture,done one last year.

that is not a vaulted ceiling. its just an exposed roof truss, with a kingpost and purlins.

it will look silly as its too small
you should have a lower ceiling as it will be freezing in the winter as u will be heating the rafters up and the high ceiling.
I done my own and hid the rafters also had velux windows in on a 15 deg roof

In my humble opinion, those beams are far too large for the low height of the room. They overpower the space. Not very attractive at all. But it takes all sorts to make a world. No doubt others think that they look marvellous.

Well, according to our architect this is a vaulted ceiling and when I search online this is what we find, but I'm willing to be told a different term.

As for why we want it, this describes it perfectly:
"Vaulted ceilings give rooms a light and airy feeling. For one, vaulted ceilings allow for skylights, which are more difficult to install in a conventional flat ceiling. Also, vaulted ceilings can make a small room feel like it has more floor space, even though it does not. "

Its a small space and we want it to feel bigger and we absolutely love the look. This to me is stunning (ok, its taller than we'll have but it gives a good example):


As for the energy efficiency, its something that we will live with and do a lot of research on how to best insulate - most likely over and above the building regs.

The beams will not be that thick, they'll be made in proportion.

of course it is a vaulted ceiling,build a vaulted roof without any cross members from plate to plate and the walls will be pushed out,unless you use a steel frame.Yes your room will feel far more spacious,and as long as the timbers are not oversized it will look great,done a very small barn conversion and the vaulted ceilings make the place,as for heating,if the insulation is to current building regs then no problem.

Is the roof going to have a ridge with a slope either side like an ordinary roof of a house or is it going to just have a single slope (mono-pitched)?

Also, are the trusses going to span the long or the short direction?

Hi,

It's going to have two trusses at 1/4 and 3/4 of the way down the length of the room, so are across the short length (will be around 3m wide). It's a pitched roof that you'd get on a traditional house, so two slopes. There will also be two windows in the roof - don't know if that would make a difference.

Thanks
