ashthekid Posted October 11, 2022 Share Posted October 11, 2022 I am looking for a decent soundproof door for an internal doorway that won’t break the bank. I’ve seen companies like Enfield that specialise in them but we are talking thousands rather than hundreds. Any ideas or tips? I’m considering doing a double door for extra sound protection. Silly idead? Link to comment Share on other sites More sharing options...
Moonshine Posted October 11, 2022 Share Posted October 11, 2022 (edited) This is all on the assumption that you aren't looking for crazy high levels of sound insulation. What is it you are trying to reduce the noise from? A standard solid core door (e.g. 44mm) will suffice, where you want to really pay attention to detail is the perimeter of the door at the jambs and threshold. Door jambs are fairly simple, its the threshold which is more tricky, and you will be looking for a threshold plate or a drop down seal Have a look at some of the solutions here https://www.lorientuk.com/acousticsearch/results?drawId=search-product Edited October 11, 2022 by Moonshine 1 Link to comment Share on other sites More sharing options...

CalvinHobbes Posted October 11, 2022 Share Posted October 11, 2022 A lot of studios getting decommissioned, for example LWT on the Southbank. Perhaps recycle one of theirs? Link to comment Share on other sites More sharing options...
Adsibob Posted October 11, 2022 Share Posted October 11, 2022 I ordered a system that I think was lorient tech or similar from a company based in Enfield. Came to about £1100 without handles or locks. Not cheap, but worth it in my opinion as it really works well at isolating our utility room from the rest of the house.

I would be interested to know the details on that and what the claimed Rw for the system is, that seems a lot a of money. The configuration below with two types of seals on the head and jambs, and drop down seal gives a tested performance with the 44mm fire door or Rw 39 dB, which is damn good for a door. The material cost of these seals is probably in the range of £50-70. Link to comment Share on other sites More sharing options...
Adsibob Posted October 11, 2022 Share Posted October 11, 2022 Good luck getting those parts for that money. Yes, the seals on the two uprights and the top are just bits of rubber, but the drop down seal is more complex. I could only find the drop down seal as a standalone item for about £90 quid, and it was rather unsightly, as not integrated within the door. The price I mention was for an FD30 door (might have even been FD60) sold as a Doorset with frame, stops etc, and all seals fitted/rebated, ironmongery fitted (but I had to supply locks and handles, they supplied four hinges) and spray painted. I will see if I can find the rating, but it’s good enough that it eliminates noise of a washing machine, tunble dryer and 35kw system boiler.

LAS8001si - £24 inc vat (https://www.noberneseals.com/product/lorient-las8001si-acoustic-threshold-seal/) LAS1212 (for all jambs) - £13 inc vat (https://www.noberneseals.com/product/lorient-las1212-batwing-seal/) LAS1011 (for all jambs) - £13 inc vat (https://www.noberneseals.com/product/lorient-las1011-firtree-seal-4mm-blade-las1011/) about £50 with some added on for delivery. The drop down seal is fitted by making a 36mm deep groove along the centre of the bottom of the door with a router, and drops with a push button onto the door lining when the door closes, hothing really that complex https://www.lorientuk.com/files/resources/LAS8001K-si-fitting-instructions.pdf 1 Link to comment Share on other sites More sharing options...
Adsibob Posted October 11, 2022 Share Posted October 11, 2022 That’s brilliant, wish I had a time machine. I guess I paid for the labour of cutting and putting all of it together because it was delivered with everything all in its place, which made installation very easy, I think they call it “pre-hung and painted”. Looking at the paperwork now I see it is only FD30 but rated at a 40dB reduction, and they fitted the locks and handles which I supplied, after satisfying themselves that the locks were fire rated, whatever that means. Total price was £815 plus vat and delivery. Seeing what you’ve found, clearly this was very expensive. I will tell myself that the customer service was decent: there was an issue with some of the painting having bubbled up. The day after I raised the issue they came to pick up the door and two days later it was back on site and paint issue resolved. That was about 6 months ago and we’ve not had a problem with it since.

Or should I avoid it? FWIW my pretty standard (glass+wood) eclisse pocket door works surprisingly well and it has no deliberate acoustical treatment Link to comment Share on other sites More sharing options...

I cant find the las8001m easily for sale on line, but i norsound do one but is expensive (not shure how it compares to the loreint one. https://www.ironmongerydirect.co.uk/product/norsound-m-12-ws-locking-sliding-door-acoustic-drop-seal-958mm-length-637182 Link to comment Share on other sites More sharing options...
