    Importing lights from China

    I first used AliExpress about 6 years ago when I purchased a memory card when they were still expensive for a digital camera. Saved a load. It was $5 so wasn't a big deal if it didn't turn up. Worked great and have made loads of purchases since. Screwdriver drill bits, cables, pencils, digital thermometers and even a phone and phone covers. The phone is xiaomi which is a well known brand not available here. Still have it as my main phone two and a half years later. Only about $100 which is great when you consider the price of top end Samsung and iPhones here. This year I've bought loads of lights. I bought one spot light first to check it's quality, brightness, light colour and get the other half to approve it aesthetically. I then went and bought another 50 or so but in batches of 10-20. If you buy then in batches you'll sail right through customs as larger boxes and orders have more chance of getting stopped by customs. Delivery is long (2-3 weeks) so you can't be in a rush. If you get DHL or another courier it will get stopped by customs no matter what the package. I've since got kitchen island pendants, dining table pendant, wall lights and really happy with all I've purchased. I've to get more lights for the bedrooms and a large one for above the stairs. I've a few pages on aliexpress bookmarked and will be getting them over the next few weeks. Another thing I'm considering purchasing soon is replica designer furniture. Original certified replicas of classics can cost thousands while Chinese replicas can be got for a fraction of the price. I've a Eames DSW chair from Vitra that was several hundred and 4 replicas that cost $30 each. The real is better quality but not enough to justify the huge price difference. I'm looking at a designer coffee table, bedside lockers and a few other bits. Would happily recommend buying Chinese imports for a lot of stuff.

    Willis Heater in an unvented system

    Have this in my house. Have it on a standard immersion timer currently as it's not long in and still slowly raising the temperature of the slab. Haven't needed it much yet as the heating season is only starting. Plan to connect it to a thermostat on the wall in the soon somehow. How would I go about connecting this to a wall thermostat? I've a three core and earth and a cat-6 cable going to where I want the wall stat in the main living area. Want something simple and not overly complicated to go with the simple heating element.

    Pitched roof thickness and insulation

    You still need an airtight layer which the vapour control barrier performs. Having that tight between the plasterboard and underside of the PIR will mean it will have thousands of holes in it from fixing the plasterboard making it useless. I wouldn't use 12x38mm timber counter battens. Timber is cheap in the grand scheme of things and the labor involved won't change. 12mm is very thin and will split from the fixings that go through it. Remember it has fixings that will be circa 150mm long if not more so probably 5 or 6mm diameter that go through the insulation into the rafters. Then additional fixings to secure the tiling battens. If the tiling battens are only fixed to the counter battens, which is usually the case, and not fixed back through the insulation into the rafters then you'll have the tiles supported on thin 12mm timber. First storm and the roof will come off.

    Pitched roof thickness and insulation

    You need plasterboard then battens to form service cavity. It will need to be large battens (75-100mm) if you've MVHR or just about 35mm if only electrics and recessed ceiling lights. Then vapour control layer and the 180mm pir insulation inc rafters, counter-battens, tile battens, tiles, etc. The 38mm counter-batten is required to prevent water pooling behind the tile batten and allow ventilation so yes it's required. Very long screws to fix through the insulation.

    Paint for concrete floor?

    Is the cafe used for preparing food? It complying with environment and health regulations is far more important than colour. Don't know the UK regs but in Ireland you pretty much have to put down some none slip vinyl in the food prep area unless you get a very smooth finish on the concrete which still has a slip resistance. I can't imagine an 'old barn' wall would pass either and at the least would need a smooth plaster finish if not whiterock, tiling or other cleanable smooth surface. If you don't know the regs I'd contact the local food safety officer and see what they want for the kitchen / food prep area.
  6. I dealt with Joan Pisanek who was helpful. Obviously don't want to post contact details publicly but if you ring SunAmp and ask for the direct contact number or email that will work.
  7. For me they arranged international shipping. I presume the same would apply to France. Its a house refurbishment so don't have to comply with new energy regulations. Also as an architect I can sign off anything I want on my own house.
  8. Happy retirement. I join the SunAmp club when mine arrives tomorrow. Think it's the first in the Republic of Ireland.
  9. Worked on a theater and in the backstage area we wanted very durable dressing room worktops. No matter what manufactures tell you about easy to clean surfaces they're mostly designed for food based stuff like wine, coffee, sauces, etc. I gave samples of different products to the girls in our office and all products failed when attached with makeup. Ended up going with an industrial vinyl floor covering on the worktops.

    Sticking PIR to OSB3 on a flat roof

    I encounter this question regularly (just out of a meeting this morning on this for a client who's mechanically fixing a Bauder membrane on the laps through the PIR into the WBP deck). One question asks loads of questions. What's the build up on top of the PIR? That's more important. If you've a roof membrane that's mechanically fixed then it will have to be fixed through the PIR to the structure below. What thickness is the OSB? If the structure it's fixing to is the OSB then will the pull out strength be enough? You'll get a stronger fixing from ply and you'll spend ages looking for the structure behing trying to fix back to that. What's the uplift and wind load? If the roof is sedium it's weight will hold it down. If the roof membrane is stuck to the PIR then the PIR needs to have a certain bonding strength. This is easy to achieve and certify by thermally broken fixings at xxx centers but how do you get that from foam? Who's going to certify how much foam you need and sign off on it?
  11. Some local authorities already have this in Ireland for a while already. Dun Laoghaire (an affluent area of south Dublin) brought in a passive house standard for all new builds. This was later modified to Passive house or Equivalent as not all buildings could meet the certified passive house standard due to site or other usage conditions. https://www.irishtimes.com/news/environment/new-buildings-in-dun-laoghaire-must-adopt-low-energy-standards-1.2103215
  12. Have a 5.5 meter long Internorm lift and slide. Did a lot of research at the time comparing quotes and very happy with it. I've installed it flush with a polished concrete floor. Yes it wasn't cheap but my issue was not many companies could do one 5.5 meters long without dividing it into smaller parts. At 3.8 meters you might have more luck. You can go for Internorm PVC with aluclad instead of the timber with aluclad and save a bit if that helps.

    Grass / living roof

    It depends on the type of grass roof you want. You’ve three broad types. Lightweight which is about 1 or 2 inches of soil that contains sedum plants and mosses. This requires very little maintenance and isn’t suitable for regular access as the soil is so thin. The next is extensive green roofs which are deeper (about 3 to 7 inches) which allows you to plant grass and flowers and you can walk out onto. This needs a little more maintenance but not much. Then you’ve intensive which is anything bigger. This allows you to have a real garden with paving areas, grassed areas, shrubs, etc. The maintenance is like a regular garden cutting the grass and trimming shrubs if needed. The heavier the roof the more structure you need and the more expensive it gets. You’ll also need handrails and parapets for when people are using the roof. The lightweight sedum roofs are relatively cheap and can be on a timber frame structure. They come with their own build up of layers and are relatively easy. The key point is it’s all installed correctly as like any roof finding a leak later is difficult. Presuming you don’t need access and the lightweight is OK for you then it should be about the same price or not far off. They don’t need handrails as they don’t have regular access. The heavier grass roofs get very expensive. I’m not sure I’d trust the regular roofer down the road with a zinc roof. Slates sure but not zinc. The same is for a green roof but the layers and build up of a green roof are now relatively easy to lay and install. Environmentally and aesthetically the green roof I think is better and what I’d go with. If you’ve high bedroom windows that look out over a flat roof it’s nicer to look out over a grass roof than slates or zinc.

    Master Ensuite Layout

    Looks a lot better. Bedroom 2 & 3 are closer to rectandular (with small entrances) rather than the difficult L shaped previously and the Master Suite is still a considerable size. What's the small little room creating the third middle door between the bedrooms off the landing? Is it needed as you didn't previously have it? It's created a lot of doors in a row squashed together.

    Master Ensuite Layout

    It's not that they're cramped. It's just they're 'small' when compared to the master suite. Having one bedroom, dressing area and ensuite larger than the two next bedrooms is out of proportion for the house. You kinda have a problem as you've too much space in the master suite. Not sure what stage you're at. If it's still early design I'd swap the master suite to the left. If it's first fix just continue and try and resolve the ensuite.
