  1. I'm sure the market will change eventually. One small change I've noticed recently is that Travis Perkins online prices are now much more reasonable then they ever where before. They now actually reflect a real world price rather than the massively inflated prices of yesterday. Even Jewson has started giving some prices on the website. I wonder whether Amazon will provide the impetus on some of this stuff. I found the Spax stainless steel screws I needed, sold and delivered by Amazon on next day through prime (Screwfix couldn't give me an availability date for their stock). I've also just ordered some Aluminium Butyl tape, again on prime. Amazingly, for one particular need, I bought bags of 5 and 10 small stainless bolts for pennies each from the marketplace. The other thing with Amazon is that I've found some small independents using the marketplace by buying items and they send a business card with the order for future supplies. I like to avoid Amazon whenever I can but when needs must and all that.. I've dealt with a few suppliers like this now, from nail gun nails to guttering to render. Works really well. If you're lucky enough to find a builder who'll tell you what discount they get. You'll probably also find that you get an add-on for materials supply by them - sometimes 10-15% rather than the discount passed on. To me that's not entirely unreasonable as one thing I've learned is just how time consuming ordering and arranging material logistics is, particularly when dealing with archaic BMs!
  2. I've avoided my local builders merchants like the plague for my build, but might have to use them for some things soon. For me it beggars belief that I have to go in there not knowing what price I'm actually going to pay for a particular product without waiting to see if the person on the till is in a good mood or not, or having to go through the painful process of getting a quote. It's like something out of the industrial age and they haven't moved on since. I've recently found it amazing what I can get delivered on the various pallet networks, for not a lot of money. I got a quote for 19mm x 100mm interior cladding (cover of 86mm) a few weeks ago and it was £1.16/m plus the VAT at the timber merchants I use. Lucky you! I'm currently mid way and unlike @ProDave's rant, my daily tantrums can't be published. It now just takes something like nobody having some basic stainless steel screws in stock so I can finish a job to push me over the edge! I've also been sitting there looking at three different options for fitting out the first floor due to both price and availability problems - the original design looks like it's now out of the window unless I want to sit tight and wait to see if things settle down.
  3. Personally I'd be taking a serious look at the tape. Once you've used tapes instead of foams/sealants, you'll not likely want to go back. Also, when you have very small gaps between insulation and rafters, it's very difficult to get the foam gun in there to fill and you can end up with several mm gap that only gets taped. Whether it's still the case, PIR has been known to shrink with age so any small gaps left over may expand.
  4. I can't see a photo but as for square bays it's usual to have corner posts. With the steel posts, you'll simply fix the windows to the steels and cover the steel posts with trims and insulation to reduce cold bridging. In a way this'll save you money on having to buy corner posts from the window company. My square bays, for example, have 109mm x 109mm corner posts plus the profile of the window frame @ 36mm each side. I worried how it would look but once installed it's surprising how the posts disappear from view from the inside and just look like a natural part of the window from the outside. HTH
  5. You could also look at Xpanda tape sold by Qualitape and Lynvale expanding foam tape. Both with BBA certificates. Neither quite the deal the ProClima tape you mention above, but when I bought from Qualitape online, they got in touch to say call them next time and they could give me discounts. They also sell all manner of other useful building tapes including Siga tapes. Perhaps worth a look. I've tried several brands of expanding tapes now and I honestly can't tell any difference between them - I'd hazard a bet they all come from the same factory somewhere...
  6. Spot on, here's one
  7. If you take the BBA certificates seriously, both Norbord (SterlingBoard) and Kronospan say the OSB: "When used in high risk areas, such as kitchens and bathrooms, the panel must be protected from wetting, eg by providing a continuous waterproof covering, turned up and sealed at junctions with walls and where services pass through the floor." Here's a link to Sterlingboard BBA - And for Kronospan -[0]=express-services&args[1]=downloads&args[2]=United-Kingdom&args[3]=certificates-and-datasheets&args[4]=kronospan-osb-flooring-bba.pdf&show=1 I've tanked the osb directly in my bathrooms over the whole floor using liquid membrane over which I'll install the final floor covering as overall it's cost me about £60 thanks to a deal. For me it's worthwhile insurance. With the kitchen I'm just applying the membrane below and around the wet areas. As for longevity when not protected, I had osb subfloor where there had been a pin hole leak in the central heating system spraying water up against the osb under the suspended ground floor. It lasted 2 years like that and what alerted us to it was a large black wet area appearing in the floor. Despite this the floor area didn't lose its structural integrity - you could still walk on it an a sofa leg was resting in the middle of the patch.
  8. It's hard to say for sure right now. Bank of England sees this as a short term blip as a result of Covid that won't cause long term price inflation but that averages inflationary pressure across the economy as a whole and as we know a lot of the economy is still holed up for the time being. I also don't think construction is fully back to normal yet either. The more worrying side to it is that with timber, for example, demand has been growing slightly faster than supply over the last decade or so, which has shown a slow uptick in timber prices year on year. Now we've got the bottle neck caused by Covid, it's going to take some time to flush it all through. There are other issues in that the US government has decided to increase duties on Canadian lumber imports, which at the moment will drive more importers to look to Europe for supply (because North American and Canadian lumber is a traded commodity with sky high values right now, up over 200% since August last year). Supplies are difficult right now which means some planning ahead, or as has been the problem I've faced throughout Covid is having to build, not according to sensible sequence, but doing a bit here and and bit there as materials, fixings and other bits come through the door (it's very frustrating and slows things down a lot). As it is, I know of smaller building firms and trades that have had to stop work because customers won't go ahead with price uncertainty and they can't get the supplies they need (there's a new house being build just down the road from me that's pretty much halted for a good month or so now with partially completed walls). People will also eventually see some sense and stop paying stupid prices for materials. This will eventually have enough of an impact on the market to ease supply problems and bring prices down (even if only marginally as they never seem to go back down to previous levels do they?). Where you are at the moment, it's probably more sensible to consider the timeline for your project and consider the risks in that light. If you're only just buying plots right now, I anticipate that by the time you've got planning and everything else lined up there may be a longer term more stable outlook. But who knows, we're in very strange times right now.
  9. haha, I did the same the other day as the site said they had stock, tried two locations but got phone calls cancelling about 20 min after putting the click & collect orders through.
  10. Do you need it in a complete roll? If not, I'd call a local metal stockholder and ask them to cut some sheet into strips for you. Otherwise, some roof merchants hold 0.6mm coil used for copper flashing. You might have to spend an afternoon on the phone. Both these sources will be better than craft suppliers on price.
  11. Yup, I had to drive to 3 different places last week for just 2 bags of the stuff. I think I was fairly lucky as where I got mine they only had about 12 bags left. One of the places said they're hoping for 670 to be delivered on the 29th May "so get here early"!
  12. It's an unfortunate condition of the market right now. Given some of the timber price hikes I've recently had, less than 10% is very good going. Some timber products are up more than 100% in recent months. My timber merchant said they'd received a 44% increase in one day with one supplier. Some of the issues are simply down to supply and demand issues due to Covid, but there is also a massive increase in timber futures, along with Brexit and the fact that timber demand has been growing for the past 10 years with not a great increase in production. I know it doesn't help you directly, but may help alleviate some of the pain knowing that it isn't down to the timber frame company. Have you asked the timber frame company about how your contract stands for future payments and price increases, or does your next payment lock the price in?
  13. Apart from that they really don't seem to know what on earth to do, I suspect a lot of this is hot air, merely using the time honoured political communication strategy of informally leaking extreme end of possibility - really bad, unpleasant and unpopular ideas - to then gauge push back and outrage, finally resulting in a policy that rows back on a lot of it, but seems to everyone much more reasonable. Unless of course the government is riding so high on its own self-belief, it thinks it can get away with what would almost amount to a new poll tax. For all the other talk of national economy and the importance of investing in infrastructure, there seems to be a glaring hole, screaming for investment into renewable energy infrastructure, development and implementation, including various storage technologies. Hopefully that is built into the new policy somewhere in a way that doesn't just rely on private companies but looks to develop a national public resource for the long-term.
  14. It's been a good few years since I did any tiled roofing but one thing that's bugging me is I don't see any kind of soaker at the roof and wall abutment in this photo. I'm almost sure from my vague memories that you need soakers when using plain tiles and that flashing only above the tiles is unsufficient in this case. Perhaps someone with clearer, more recent memory can confirm, or maybe a google could provide the answer ..
