I am thinking to do it by my self now :)
Great way of showing external wall insulation install.🦁👍
Thank you , professional and clear explanation
Fantastic video
Excellent video and job mate.
Thanks for your comment!
Excellent clarity and communication. Alhamdullilah. Have an enjoyable safe Xmas.
Ws salam.
The best guide! Well done!
We're glad you found this helpful!
Amazing , thanks a lot , very useful @
Overall a well presented video, but how is the plinth dealt with below the bottom bead?
Good Video, Really Useful
use this ratio
Thank you for the video. Getting ready to do external wall insulation on my house . I had a couple questions, but you cleared them up for me.
I guess im asking the wrong place but does anybody know of a trick to get back into an instagram account?
I somehow lost my password. I appreciate any help you can offer me!
@Keaton Luis thanks for your reply. I got to the site through google and im trying it out now.
Takes a while so I will reply here later when my account password hopefully is recovered.
@Keaton Luis It worked and I actually got access to my account again. I am so happy!
Thanks so much you really help me out !
@Wayne Bodhi No problem xD
Hello, could you advise what kind of bead to use to make nice border line on semi detached house or just to use a corner bead?
Do I need to use a base track with clip drip beads around the roof line on one story extension and what width to leave between roof tiles where lead work and eps on the wall. Using 50mm eps. 1.5mm render. Thanks in advance
Fantastic vid as i m working in Portugal on same
Central and Eastern Europe using this technology for long decades. Glad to finally see it in the slow adopting UK. When you feel cold you put on a jacket don't you? House should too.
Cold bridging around the external window reveals and potentially between the joins of the insulation. Ideally the joins should be sealed or foamed to help prevent this happening.
Correct
What is the fire rating/properties of this EPS over brickwork and rendering?
How would you change the window in the future
Can i apply the primer onto painted concrete/clay bricks. Can i apply onto wood?
I got old house where a wooden beam sits ontop of walls throughout house. Then the roof sits ontop of that? Would i get any thermal gain by adding it onto the wooden beam? The beam seems to be thick enough to keep nice thermal delta.
Very usefull video. Great job. How dis you attached Window sill? Doesnt seen to be showing
Not very good spelling
Jamie Leach but video is great doe :)
Excellent Video. This was a demonstration for a Single House. Can this same solution be scaled and applied to 10 Storey Concrete walled buildings???
Yes, all of our systems can be scaled up.
Great vidoe thanks, can your EWI system be installed on a timber frame building ?
Hi, this is the EWI system buildup for externally insulating on a timber frame building, hope this helps.:) ewipro.com/walls/timber-frame-build-wood-fibre-insulation-system/
Is planning permission/building control required for any of these works???
After the Grenfell Tower disaster some insurance companies are requesting any external cladding system used must be made from a fire resistant material. Polystyrene insulation while different from what was installed at Grenfell, is being seen as a potential fire spread risk. Small numbers of mortgage lenders are now insisting this is removed from any building before agreeing to any sale. The insurance industry sees any suspect cladding material as too risky and will refuse cover.
Lee Thornton, I asked EWI store about this subject as I’m halfway through putting it on my place.! Once rendered the system is difficult to ignite so can’t see why insurance companies are being a pain in the Arse.! It’s one of the most used materials for external insulation.
@@nigelsmith1198 Hi Nigel yes it will be very difficult to ignite and the risk especially on low rise properties to occupants would appear minimal. In the organisation I work for we are having to survey all our low rise buildings that have cladding and in the very near future probable the houses with cladding also. As a company the insurance of the buildings is a major issue and we will be unable to cover the buildings if the insurance firms see any potential risk. You only have to look at the problems asbestos caused in buildings and insurance firms refused any cover if there was a potential risk so certain types of asbestos had to be removed. This is all an ongoing issue but you can be sure if a building with cladding went up in flames and the cladding was known to be a risk and not removed any insurance cover could in the future be void. Has we stand now nothing has been finalised but be aware even if the risk is low the cost of getting insurance could be very high sometime in the future. At the moment it is all in a state of flux.

Hi I have tiles n he fronand rear wall of the house and was wondering if his system can be stuck onto wood as once e tiles are removed I would have to put boards onto the battens left behind as ere is no brickwork behind
How do you finish on a gable end apex roof,tiles finish flush with roof
Hi James!
There are two ways - 1. You can extend the roofline or 2. Install a robust capping profile or verge trim. You need to double check if you are going via a funding scheme as they may only allow option 1.
Hi how do your products compare to K rend? (Prices, install costs etc). And are there any opportunities to supply your product to trade? We are a builders store in Dagenham, east London
Good product, you’ve missed how to install oversills tho , I’d like to see it in details ie take out existing one if there is and fit new oversills plz
This is the video that does not exist anywhere, been hunting for ages
Top video, 16.14 when the knife is stuck in the insulation made me laugh. Where can i get the window protection?
Thanks for your comment! The window protection film is available on our website here: ewistore.co.uk/shop/window-protection-film/
How do you do window Bays?
En México se aplican varios tipos de sistema EIFS pero para mi que he sido instalador sólo hay uno efectivo,enlos videos que he mirado aplican dos sistemas enuno
Great video, but it misses out all the hard bits, like guttering, soffits boiler vents and electric/gas boxes
We're hoping to get some of these videos out soon!
What about window sill? It’s easy to show on a demo wall ..
Here's one for you (and any builders). I want to add 100mm EWI my house with a render finish on the ground floor and vertical hanging wall tiles on the first floor. How on earth can I hang literally tons of vertical tiles upstairs securely? Any advice appreciated
Hi David, feel free to drop our team a call on 020 3397 4067. They'll be able to have a chat with you!
Wow! Very impressive! Do you know how one can install these insulation pads (90mm) on a curved wall?
Hiya! We would always recommend using a verified installer for complicated works like this!
Usually, blocks are cut and filed to size to keep the curved appearance!
Hey EWI, I also got a client who's got a down pipe. The normal plastic plugs that screw into the insulation won't hold properly. I'm thinking of using 150mm wall screws to hold the down pipe bracket. So that the screw can go through the 90mm insulation and Into the wall. What do you recommend?
@@mihir9578 Hey! Please drop us a call and our team can discuss in more detail! 020 3397 4067
I'm getting the ewi under the government scheme but my workers are drilling on the foam instead of using adhesive for sticking
Hiya, if you are getting EPS then this requires certain fixings as well as the adhesive. We've got lots of handy information on our blog - ewistore.co.uk/?s=EPS
@@ewistore what's eps? mine is ews they have applied an undercoat on top of the foam and will just apply render on top
Would this be any good on an integral garage wall that's solid brick ?
The rest of the house has cavity insulation but this wall is part of the main bedroom
Yes, this would work perfectly!
How do you screw something to the wall, like an external light, if the fixing is going into polystyrene?
Long screws
If it’s not load bearing ie hanging baskets etc , use drywall raw plug and screws,.
For gates etc you need to fit timber batten same thickness of the insulation to prevent damage!
Can this be used on a Victorian stone house
Is this breathable for use in older solid walls then need to breathe? How do you deal with none 90 degree corners like bay windows etc?
Hi! Please give us a call and our team will be able to answer your question in a bit more detail!
Question what happens in years t come if you need to change out the window?
Change them from the inside
Can we use xps? And are there higher density xps boards? I want to use it as a core material for a composite sandwich
XPS is normally used as an insulation below the DPC or as an insulation on balconies due to its water repellent properties. XPS density is circa 200 or 300 grade for these applications.
Would you be able to recommend some good external wall insulation installers?
Hi for information on an installer you can email our prospects manager- alice@ewistore.co.uk
i recommend this ratio
What is the lifespan of this product?
Not ok over T-111 wood siding?
What's the reason of making holes and insert fixings?
Because they don't have much faith in the adhesive for sticking the insulation
How do I get a quote for my house?
How can hang 🛰 on Insulation wall
How do you work around gutters and drain pipes ? Also is there a training course for this?
You'd get new gutters and drain pipes
Nice job. Would sack your brick layer tho. Block works a mess lol.
sack this ratio
whats the r value?
What's the average price for this insulation?
Good detailed video... However, that's some crazy Jazz music in the background. 😵
Do all installers listen to BBC 6 Music! haha
Polystyreen is extremely high flameble, see Granfall tower
Why hasn't the base coat been scratched for a better key before applying the top coat. I know u applied a primer but there no better key to apply the render than a scratch coat. Personally I'd scratch the base coat and still apply the primer aswel.
Sills, soffits, phone lines, electrical points, gas lines This is where the major problems are
Your website has pop ups on every page, forget it!
So no vapor barrier
lol that music
Looks like a good system but has a major flaw , what happens if you need to replace the window? This system does not allow for that as the base coat and thin coat both encroach on the window frame . Not good 👎
But that's the case with all rendering. Windows are generally cut out and the replacement measured to fit between the render, ideally slightly wide and shuffled in before being screwed to the sill. If the frame is narrow on the inside, trims are used, but they're normally used anyway.
Good video.
I doo quite a lot of ewi regarding your base coat and mesh. I mesh coat.
Then I put a tight coat over the mesh don't u guys doo this.
Just the way I got taught.
i believe this technique is from the 90s as the materials but cheap.
The worst fire rating you can get was given to this insulation material..avoid
God it becomes annoying once you hear people pronounce insulation as in-shul-ation. And you can't change the windows anymore, they are stuck in there.
Sho you reckon no houshe with render hash ever had replacement windowsh?
All the polystyrene waste from cutting and drilling for fixings is likely to blow over a large area. Looks like a bit of an environmental disaster to me.
i wonder what is the freaking need to put annoying music while demonstrating the technique!!!
