Did you try it yet?

Make sure that if it's a stone built cottage that you allow the building to breath. The type of insulation used here eps is not suitable as it seals the building.

@@bigowenzy3397 ah thanks buddy! we actually decided to go with the Sheetrock backed insulation boards inside!

@Luke Jarvis If you going to fit this type insulation you mention I advice for Ireland type of wet weather to sand & paint the wall with damp seal paint if you find it expensive then buy cheap white paint & add mould killer into it very important to do that (always wear goggle and mask) then when it dry stick to the wall plastic sheet the thicker is better then fix the insulated plasterboard trust me will make a big difference. Best luck with that

@Luke Wayne sick bastard

Crikey, that's scary!! I wonder if a way to avoid this fire risk

That's because they might have used Kingspan , fenolic insulation. The kind that killed the people in Grenfell Tower in London . EPS or PIR is fine, not flammable .

hi Paul.i have been applying this render for decades, where the boundary line of an adjacent property i e semi detached ,with this system there is a stop trim that runs from top to bottom that is mechanically fixed and silicone applied. Some firms will return the scrim on a bead, like its a window reveal for example. If there is already a "decorative" finish a lot of care is needed and the trim/bead is applied as near as possible to it.

I have no idea how these guys do it. When my house was done, everything outside the house was taken off, satellite dishes, drain pipes, security lights, alarms, outside taps etc. blocks of wood was fitted to the wall, the same depth of the insulation used and then everything screwed back in to place, but into the wood, not the wall. Then someone else comes along, fits insulation, render/pebble dash, job done.

@Dans Channel Did it insulate well in winter ? How warm the house after than before insulation? Did the rain had any bad effect on it ?

@@trysam we only spent 1 winter here before the external wall insulation was fitted. If I’m honest, I don’t know how much difference it has made. My house is not a warm house, it doesn’t hold heat well either, but that could be down to a number of reasons. The only effect the rain has, is the same effect it has on the normal wall.

Yes true, we also use this method in our country over 20 years now.Most of European countries do it like this.

Silicone Sealant

Very strange situation only your house or others in the area ?

@@trysam I’ve no idea. We only spent 1 winter with out the exterior wall insulation. If I’m honest I couldn’t tell you if it made a difference or not. It is cold of a winter, a lot Calder then my parents house which is a conventional construction. Doesn’t hold heat well either but, that could be down to a number of reasons.

I did my own ewi and the house is warm and dry in winter. Cool and dry in summer. For as long as I'm in good health, no trade comes in my house. I can do better than them.

It’s piss easy

You can ether fuck em ir render and you can t fucking render

@@tomwelford your comment is completely unintelligible. I have no idea what your point is.

Al guess you'll never know then aye

@@tomwelford well done on another great comment. You've made a fool of yourself twice in one day. Congratulations.

They did a full prefab ex coal board estate near me. It's crap mate, the depth of the reveals round the windows you could park your car on! And the cut outs for the drain pipes etc look aweful. Plus it's really soft there's only like a hard skin on it....slightest knock and it outs a big hole in it. I was digging out a garden of one of the house with my mini digger, piling the spoil up and a bit of concrete rolled towards house put a great dent in wall...😳 It's not good ...but I guess it's the only way to insulate a prefab house....wattle and dorb would be better...😂😂

Agree....after a year the effect of lacking ventilation shows its destructive effect on the internal living space. A pity this is not addressed in this type videos. Unfortunately this problem is hard to solve in old buildings. Again, this type of insulation does reduce the energy bill effectively of course, but the internal build up of humidity that can no longer escape through the walls, causes internal wall paint and wall paper to turn black, grow mushrooms after some time.....

@@paulbrands6239it’s we’ll known that when you insulate a house in this way that humidity is the next problem. So a dehumidifier is needed.

@@hearthjunkie8173 if there is a ventilation shaft in the house then simply getting a grill that's more open and leaving the windows on micro-ventilation can do enough to balance out the humidity. The main issue is that some people do not care, if you insulate your house you NEED to buy a thermometer with hygrometer and monitor the humidity in the house, if it's constantly high and improving ventilation doesn't help then you need to get a dehumidifier. Usually dehumidifier isn't required, because in winter the air outside is dryer (because it's cold) and you heat up your house, there is a drying effect and in the summer you usually have AC on (or at least I hope you do if you're renovating the house already).

What is point of insulaing a house to then have to bring in cold air through vents in winter to deal with moisture build up? Any cold drafts are going to make it very inefficient to heat the space?

If its uneven and you can see it at angles you're not doing it right. It's a craft and takes lots of effort and time to learn properly.

The property originally had a F38 rating and improved to D56 after the work done

I've been told my single skin 1900 built house will go from D58 to C52-70 with 50mm mineral wool external wall insulation. This can be in the form of insulated plasterboard with at least 25 mm PIR. I got a MEES report done by the company who provided the EPC report as I want to guarantee I'll get a C if I do the work! They also said I need loft insulation on south side and a new boiler (specific as I've already done it! They ask you what you've already done before running the report) and low energy lighting. If you're interested I used Easy EPC but I expect most EPC firms offer the MEES report. It cost about £65, EPC was about £60. You can ask them questions too, so I'm really pleased I got it! Now getting quotes for external insulation. This is a great video! Have emailed you guys for help finding contractor

You will always see a little unevenness when the sun shines in that direction, but if the unevenness is always visible then it is not good

If you got four guys on the job you will be able to finish external wall insulation on your propertyin and about 5 to 7 working days depending on the weather conditions

The basecoat can, but the topcoat really doesn't blend in well. You need to go in mob handed.

If you spray it you probably could get away with it,using trowels and floats no chance it would be an eye sore

@@beatonthedonis Now I have a front porch similar to this size, I want to insulate it like this but I want to cover it in stone cladding to Finnish it. Should I put a coat of render on the insulation board then put the stone cladding i on after that?

1. Fire safety - no ventilating behind when bonding as you bond on all the perimeter of the boards trapping any air. Also you then have plaster adhesive at both front and back of the boards. 2. Loading - both mechanical and bonding produce far superior pull off tolerances to wind etc. 3. You actually don't use any less basecoat dry fixing because you normally compensate using extra basecoat to get it level. 4. Bonding first allows you to fix straight, which again gives better structural performance. 5. Bonding secures the boards to unlevel surfaces much easier. 6. Bonding gives the system much better change of not cracking in the long run, saving on maintenance costs. 7. Both bonding and mechanical how the Europeans do it especially in Germany where systems have had longevity 30-40yrs plus. The dry fix method is a British 'cost cutting exercise'

@@BeConstructiveLTD Cheers for the reply. I did think of some of the points you made as I watched the guys fit it to some neighbors' houses. We're in NE Scotland around 50 yards from the sea and regularly get winds gusting over 80mph or more through the winter and I did wonder about it being cracking or being ripped off. But of a shame though because it is more or less being done for free to eligible houses by the Scottish Government, but you can see our contractor is doing it as cheaply as possible. Wish we had a choice of contractor.

Dropdown Verge Trim is designed to go under sills, soffit boards and applications that require fixing from below. This Verge Trim is available in various different widths to house different thicknesses of insulation. The Dropdown Verge Trim effectively ensures that water falls away from the system but minimises the requirement of expanding foam tape and/or a silicone sealant to ensure it is completely watertight.

We have a pft and a kaleta Works well as a render only on the 225 because you deal with larger surfaces. Haven't tried it with the insulation as the jobs have been too small.

I’m no expert in this kind of insulation. However what I would say is I can only see this external insulation being any good if your house has solid walls. If you have a cavity wall then frankly I can’t see this insulation being of any help. However I’m happy to be corrected if someone can be explained the benefits.

What , of no help ? ridiculous . if the interior walls have open cavities and the new insulation creates air tightness in the walls then the cavity becomes a dead air space . not as effective as insulation but still very good . The biggest source of heat loss in any house is air infiltration . this system accomplishes both , eliminating air movement through the walls and insulation simultaneously .

I'm wondering the exact same thing? Have you installed the socket already and if so how did it work out?

@@jay-lm4we i bought plas plugs from screwfix. They're not the best to use but they are quite sturdy once you get the hang of not breaking the plug attachment it comes with

@@MrJustbrowsing12345 I'll check them out, cheers 👍

Its main job is to super insulate, or "exulate". Its giving the house an external barrier before any of the heat on hot temps com in, and it does the same to keep the warm air in during the winters. But I see the advantage mainly in the summer and generally hot climate zones

​@@philindeblancthe advantage is mainly in winter. Keeps the house warm. Indeed, keeps it cool in summer.

On the markets that are few different types of external wall insulation window sill extension The one we use most of the time it's aluminium window sill.

Where do you get them from?

Usually will get them from ewi store

Re-rendering pebbledash without removing pebbledash can be difficult if the right materials aren’t accessible. Removing pebbledash is a painful process, because removing the render requires hard work with a hammer and chisel, with the added risk of damaging the original brickwork. One of the best ways of re-rendering pebbledash without removing pebbledash render is by smoothing over it with our One Coat Dash Cover (OCDC). This is the ideal material to use, because it can be applied at a thickness of 20mm thick without compromising structural integrity.

Is it warmer now??

From what I've heard from other people, it's a bit of a nightmare and the windows had to be installed from the interior of the house. Of course, every house is very different and a lot will vary from installation to installation

Yes you can use brick slips instead of render there are few different types of brick slips best people to talk to and get the bricks slips from is EWI store www.ewistore.co.uk

which product is the render ?@@BeConstructiveLTD

You can use the same technique replacing the glue and the screws for wood walls... Simple 😀

Look up EIFS

Yeah do all that work before

yes you can install it directly in to the brick

Yes...

@@zarron221 A few month too later, I finished the job, but had I known I would have looked further into it and used it for the one wall that gets the super hot sundown exposure.

Nothing is fireproof for wildfires (mineral insulation melts most of the times) but this insulation also melts, so no not fireproof

Don't use plastic insulation in a fire risk area. Use rigid rock wool insulation instead. More expensive, but won't create dangerous poisonous fumes when in a fire.

@@mikevlek Fireproof means it wont sustain a fire. Melting or burning, but going out is fireproof.
