    flat roof noggin dimensions

    Because the slope of the roof is 90 deg to rafters so last rafter has 0 furring, next at say 450mm, 1:40 has 11mm.

    Parapet cap - best options?

    Is what I'm trying to achieve if that helps. I suppose my other alternative is a glass roof with side furrings but then I'd end up with a high shelf that tapers to nothing. Left wall has some high windows side it would otherwise look out on to a passage way. Right side has bi-fold which...

    Parapet cap - best options?

    I'm planning a extension which has 2 parapet walls, ~2.1m long with a glass roof in between. What are my options for capping the top of the wall (which will be render btw. I'd like to keep the level low, so just above the slope of the roof, and then bring the flashing down from the wall top to...

    flat roof noggin dimensions

    Thanks for the replies. I have remember the furring but they don't make much of difference. BTW my solution is T&G OSB3, aka roofdeck or other trade names. If I use the long T&G side at 90 deg to the rafters then I don't need a noggin which makes life simple. Of course I still need...

    flat roof noggin dimensions

    In a flat roof you have rafters, say, 50x170. On top of this goes the deck, osb or ply, 2.4 x 1.2m max size. Where 2 sheets on of a roof larger than 2.4x1.2 you need a noggin, between the rafters, to support the edges of the osb/ply. What size wood does the noggin have to be? Say noggin is...

    flat roof noggin dimensions

    Hi, I can't find anywhere that says what dimensions are needed for noggins to support flat roof deck edge. Long edge lines up with rafer/joist. For short edge I read it says fit noggin, but how big? Presumably this depends on rafter/joist spacing. I don't want say size as rafter/joist...

    Which central heating system

    Thanks for info. The project is a 1st floor on a bungalow so loft conversion would be a very big house. I was planning on a large cylinder, 1500mm high, in a large (2 door) airing cupboard. So far I despair of getting sensible info from either worcester-bosch ("fit a system boiler as then...

    Which central heating system

    Hi, This is a completely new install so a clean slate. Selections so far are mains gas vented hot water tank My reason for vented is I have the head room in the loft to get >1m below the cold water tank so vented allows DIY and I have a defined flow rate independent of what the mains...

    Best flue position

    OK, That's an interesting point. So boiler replacement would mean replacing the flue as well. The roof is quite tall (if I could site the flue there). I suppose it might be possible to replace the flue up to the vent tile but otherwise that does get tricky I can see. I suppose 1st floor...

    Best flue position

    Well his would be one opinion and it is current Easter weekend. I'm looking for a range of opinions and the whys and why nots.

    Best flue position

    I'm considering an extension and at same time fitting gas central heating (not me fitting the gas of course). Everything is variable including boiler position and flue. Is it better to have the flue exiting from the roof? Or is a wall exit just as good for the risk of nuisance? I could...

    Plaster falling off - damp or badly applied?

    The undercoat is fine so it would be a bit of job to take a brick out (would be a block anyway). I don't think it is damp I think it was just poor plaster. I'm stripping other plastered walls in the same house and not having these issues. The plaster blows with the steam on it for say 10s...

    Plaster falling off - damp or badly applied?

    I can't see any sign of paint so I would say it wasn't painted before being papered. My house has some plastered walls (this is my mother's). Stripping paper off those has never pulled off all the top plaster back to undercoat plaster. I don't think the walls are damp. Bit of sign of...

    Plaster falling off - damp or badly applied?

    Hi, I've just started stripped out a house to redecorate. Walls are papered which has later been paint. The top, finish coat of the plaster is coming off. So far on the 2 half walls that have been stripped, about 90% has come off. Pull the paper seems to pull the plaster off most times...

    Landlord gas certificate or not?

    I've found a leaflet on here, a guide to landlord duties. That says "any appliances and flues serving ‘relevant premises’ (such as central heating boilers not installed in tenants’ accommodation, but used to heat them) are covered." which seems a bit daft to me but it is pretty clear cut.

    Advice on new gas installation and CH

    I run our local oil club so I know oil costs, last buy (13/1/15) cost was 34p. On my boiler (not condensing, so could take off 10% say), this is 3.91 p/kWh (plus VAT) so 4.1 p/kWh. However, I bought oil in the summer at 49p so what I'm currently burning cost me 5.64 + Vat, 5.92 p/kWh. Gas...

    Advice on new gas installation and CH

    That is one school of thought. Not keen on warm air, had that 30 yr ago and it blew dust everywhere, SWMBO would stand for that. Oil is about the same now but that could be temporary and cost of tank install is similar to gas. Easier to shop around on gas (I'm currently on oil). E7 more...

    Landlord gas certificate or not?

    I was just wondering if you need a landlord's gas safety certificate if there are no gas appliances in the rented accommodation. Say you rent a room in you house but the gas boiler is in the kitchen? Or say the house has a granny annexe that you rent out? A self contained one with or without...
