    Roof ventilation with loft conversion

    Air gets sucked out of the top, greater wind speed higher up or some such thing iirc, also your soffits face down ( and would be limited in size by the bay window) so it's not really going to be a problem. It's a little different for you as you've got a breather membrane.but the principle is the...

    Roof ventilation with loft conversion

    Just reread your thread, I feel sorry for you, as that work was poor to say the least. As you have a breather membrane, get a full length soffit vent fitted and a full dry ridge kit fitted. You could add some tile vents as well. But your vcl needs to be complete to be effective. As for your...

    Roof ventilation with loft conversion

    If you want to you can: Have a continuous soffit vent, Have a full length dry ridge kit, Install rafter trays and lap vents in each bay. For around the price of your four vented ridge tiles quite probably. The air would get to the other rafters via the soffit, the tiles and the imperfections...

    Gable insulation

    A gable end wall is going to be insulated on the inside, should there be a air gap between the wall on the inside of the loft and the insulation? If so would it be 50mm, if not why not?

    Gable insulation

    Should a gable end wall - full fill insulated cavity -be insulated with a air gap behind the insulation? If so why?

    Mathematical Challenge !

    Funny that, only a couple of days ago I was reading about the Avalanche backpack that inflates and gives the wearer a better chance of 'rising' above the snow. Got me thinking. Hot air expands, so it doesn't really rise its more that cold air is small and your granular motion comes into play, if...

    Ideal loft cable routing

    Well that's what you get when you post things that are demonstratably nonsense, lol However I do get your point and do take if onboard.

    Ideal loft cable routing

    Paraphrased as, ' don't be wilfully ignorant' perhaps? So, on topic again. A radial circuit, around the rear of the stud walls, clipped to the rafters, above the insulation, buried in earthed metal conduit where it crosses the gable wall would be a sensible way to do it.

    Dare I ask what it is I don't know that I don't know?

    Ideal loft cable routing

    I'm not vague, I'm just undecided, I can do it myself and pay the extra fee or I can pay an electrician. I've not even calculated the cost for diy or got a professional quote for comparison yet.(well actually a ball park figure from the commercial electrician I employ at work, curiousity more...

    Ideal loft cable routing

    I was just wondering, it was something I read about elsewhere, pros and cons of radials/ring and the point about a damaged ring was made- going undetected because of the return redundancy but still earthed due to that Whereas a radial wouldn't be. There's quite a lot of debate on the subject...

    Ideal loft cable routing

    From what I've gathered it's an earth going all the way back to the cu, or I suppose some other earth that's not part of the radial in question.

    Ideal loft cable routing

    That's cool, your not obliged to. But in answer to your question, No not for free, it costs £255, its on top of the building control fee. Its specifically for people who are not registered as competent persons. I.e. As I can't issue any certification to say what I've done is either safe or to...

    Ideal loft cable routing

    No mostly they reside about 400 each, but it's feasible for them to pull a 1000 each continuous, the trend though is for less wattage in general, however multi gpu optimisation is finally looking up with the onrush of 4K gaming so in the not so distant future tri and quad 1080 ti/vegas are a...

    In reality, likely max load would be, Two pc's so max 2000w, Monitors, amps, router, circa 200w Home server max 300w PS4 and monitor max200w Lamps 100w Phone, tablet etc chargers, negligible ...... Hairdryer 2000w Vacuum 800w

    Ideal loft cable routing

    The first/last is near the supply, but that might not be reason enough it seems, likely loading doesn't especially warrant it even if I am a fan of a good ole three bar fire but I do love to feel all intercontinental.

    Ideal loft cable routing

    Do you mean as opposed to a radial circuit? I couldn't give a reason, well not one that would satisfy a sparky... From what I've gathered, a ring is arguably yet slightly better than a radial because of the two returns, a bit of redundancy is created should a part of the circuit be damaged.. er...

    Ideal loft cable routing

    Yes, definitely rectangular. Out of curiosity what would you guys charge for this? Loft is roughly 7x4m with 8 double sockets straight from cu A three way switched light for stairs A two way switched for 4 down lights No access problems, no insulation in yet just framing and floor. Only...

    Ideal loft cable routing

    It's a house, the reason for a separate ring is, it's a nice straight run down a void to the cu and that has enough spare capacity. It's only a couple of meters further than the point where you'd break into the ring so not too much extra cable wise. As for literal ring, well I suppose that's...
