Thanks Mr Chibs. There is a drainage channel just under the edge of the tiles. The RHS tiles sit quite low to this channel whereas the RHS sit quite proud of it. It these are trimmed back it will expose the foam weather strip that sits just after the main channel. Is there a way to basically...

I was hoping to get some roofing advice on an issue with the the way the tiles have been placed around a Velux. The tiles on the left of the velux are sitting quite high as compared to the right. The window has been in-place for about 18 months and last week with the recent rain, there is a...

Thanks All. I've decided to change the lights to a dimmable, non-pir which should address the issues

Hello All I've had a 4-gang dimmer (varilight) installed. One of the modules is meant to control a set of pir security light (up/down type). I didn't realise that a pir would require a straight mains connection. So now the pir works fine until the dimmer cuts the signal. Is there a way around...

Cheers CrossThread. Modifying the brackets might be difficult. I'll look into the horizontal TRVs

Hello I’m trying to replace a radiator using the existing pipe work. The depth of the new rad is deeper that the existing and the existing pipes are curved. Unfortunately the trv doesn’t fit straight on and only goes on an angle. Is there anything I can use like a different valve to get the...

Thanks Woody. I knew I could rely on you for an answer. Could I get away with using Kanuf Earthwool Rafter Roll 2x75+100mm / Rafter (250mm)? The calculator comes up with .16 U. That would mean the plasterboards would only lower the ceiling height by little over 60mm as the rafters are 200mm. Thanks

Hello All, I'm trying to work out the U value requirement of a pitched roof. Its an extension roof and Building Regs require a .16 U value at the ceiling level. This is the roof makeup thus far Clay Tiles 20mm Breather membrane (0.1 mm) Air layer/battens 30mm Rafters 200 mm To get to a...

I don’t disagree Freddie. It’s been a struggle to get this far - weeks if no work, loads of stuff having to be re-worked. Unfortunately I have too much invested to cut my losses.

The rafters are unfortunately already installed and is currently providing a roof pitch of 12 degrees. The firings will be retro-fitted to these rafters and tied in as Woody has suggested with gussets. The fall on the firings will be aligned to provide the 15 degree pitch for a Velux.

you're right Woody. The architect has been a real let down. We're struggling through the build with a lot of to'ing and fro'ing with BC. Thanks for the advice.

Thanks Woody. The cost for these upstands (almost as much as the velux itself) are quite prohibitive. Also we are trying to retain a flush finish if possible. Would the firrings proposal work as this would increase the pitch for the whole roof?

Hello All, we are undertaking a rear extension and are in a bit of a situation regarding the roof. The builder has put in the header and rafters but there is a 12 degree pitch (2.5 in 12 inches) so we're struggling to get the pitch to fit a velux which I think requires a 15 degree pitch. No...

Just ran my hand across the 'red' bricks and it feels very wet with red wet brick dust being left; whereas the other bricks leave no moisture or residue when rubbed. Does this mean the bricks are wet afterall and could potentially clear up?

Thanks Woody, that's what i thought. Would that be possible from bricks off the same pallet, more rhetorical really. Is there an 'easy' clean way for them to replace these or do I need to live with it. Its on an outside wall so the BC might have something to say about it as well. And then...

Thanks Wgt52. I'm more concerned the bricks are a different colour rather than moisture, although unlikely as these were from the same pallet. Is there a way I can confirm it is moisture and not the actual brick colouring?

Just had a side wall for the extension we're doing built yesterday. Some of the bricks they used have a much darker look - much more red than than brecken grey the rest are. All bricks are from the same batch and they are putting it down to moisture in the brick. Why they didn't use the dry...

The plans will be drawn by an architect and will eventually go to full plans approval. I’m just looking at the best way to lay things out as I’d rather not rely on an architect’s drainage drawings without him having the full picture

Thanks Hugh. I’m looking at the Osma 315 multi base IC. It has 2 entries at 45 and 90 and one main channel so 4 opening in all. The plan would be to run laterals out - kitchen and wc to the 45 and 90 and the new wc at one end of the main channel with flow down and the remaining main channel...

Thanks all. That’s certainly put my mind at ease regarding the gully.
