Yes it's very odd for sure. I got up at eye level today to take a closer look an internally and they haven't even managed to seal all the way around as per the fitting instructions. In the photo you can see daylight where you should see sealant. I'm really not surprised based on experiences on...

Looking at the GAP catalogue I think this might be the product. There are no internal beads as per the diagram and it hasn't yet been finished

The grey bit is the upstand which the Sarnafil roofing has been run up the side and over onto the top of the upstand. I think there was a large internal rooflight frame that sits on top of this upstand, which the visible external rooflight component then clips onto. I don't know the make/model...

Hi All, Quick question - Our builder was left to spec and order some flat fixed rooflights this is what was fitted. I’ve never seen a design that just sits on top of the upstand, rather than go over it to avoid water ingress (which I believe is the norm)? This design would appear to rely...

Healthy conversation - I like it! The wall isn't rendered yet so this is technically 1st fix work. I've yet to ask the guy how thick the render will be though I am assuming I'll be chasing a channel to get it deep. On the topic of cable suitabability, I'm thinking arctic flex..

The wall will have coping stones on the top so I'm going use that as the 150mm datum in this instance

Only if I could get the conduit sunk deeply enough into the wall such that it could then be renedered over, surface mount is not an option in this scenario

Thanks both. I'll likely chase a channel (depending upon the render thickness) within the usual protected zones.

Hi All, Need to run some lighting cable in a yard for wall lights. Do the internal protected zones apply to external cable routes also? The cable will be getting rendered over, so mechanical protection-wise will chasing a channel and metal capping suffice, or is there a preferred alternative...

Hi, Busy researching Esbe actuators in a domestic setting and see there are a number of running times (open to closed?) according to model, ranging from 30s to 4 mins. In a typical domestic sealed CH system would one speed be preferable over another? - I assume you'd just end up with a...

Hi td2304, Did you go for the middle KVs rated valve in the end and has your choice been performing ok? I'm in the same position so would be keen to hear your experiences on this. thanks

Perfect, thanks.

Hi, When a zone valve opens and the aux switch calls for the pump to start, is there a delay after which the pump starts circulating or should it start immediately? thanks

Hi All, I've been trying to find a Vaillant (modulating) schematic for a sealed system boiler that details 1 unmixed radiator, 1 mixed UFH, and DHW but have come up short, so I have created a hybrid schematic (ignore the numbering) on which I'd would welcome your thoughts as to whether it would...

Hi All, I've been trying to find a Vaillant schematic for a sealed system boiler that depicts 1 unmixed radiator, 1 mixed UFH, and DHW but have come up short, so I have created a hybrid schematic on which I'd would welcome your thoughts as to whether it would work. I'd be looking at using new...
