Mount Sat dish to externally insulated wall

whosedaddy?

Hi,
I got 150mm EWI added on my house.
I'm looking for fixings to mount satellite dish through the EWI.
I came across Fischer Thermax , does anyone have any experience with them. or has other suggestion.
I was thinking about using 4x Thermax 10 , but Fischer seems to say only Thermax 12 and 16 are for satellite dishes - they are chemical /mortar fixings. The thermax 12 might be too short for me and 16 might just be overkill. Also they are not cheap for a tryout.

Any experience anyone?

Move the dish to the chimney stack

I agree. It can be strapped to the chimney instead of drilling if preferred

i can't really get the cables extended / rerouted from side of house to opposite side where chimney is.... (obviously I can, but it would be mega messy ripping up a lot of just finished work.)
The EWI guys where meant to fix the dish, but they now say they can't... they pointed me to the thermax

I would avoid the chimney stack if at all possible. Depending on the age of the house it could be problematic and your insurer may have issues also.
My last two home insurance companies asked if any antennas/sat were mounted on the roof.
Lashing kits can be effective on newer homes but I would look at all other options first.
Sat dishes can be effective even at low levels, close to the ground.
It maybe possible to mount it on a garden wall without being intrusive.

Download dish pointer or other sat search apps and try different positions.
If you have to go for the chimney, check it out and buy a good lashing kit.
Under no circumstances try to bolt it directly to stack.

The ewi guys should have brought out a timber block from the wall of the house to close the gap in the insulation. Mounting a dish even with specialist fixings risks undermining the final render coat.

I moved mine to the lowest part of the chimney stack it's just above the roof level. It's been there two years no problems. I've a bungalow which isn't impacted by prevailing winds.



Never had an insurance company ask about satellite dishes though ever.

Ordinarily I wouldn't recommend fixing to stack if there are alternatives. If there isn't it's the obvious place. They've been fixed there for decades until sky stopped due to height restrictions working directives

The EWI guys fcuked you over here to get the work

So all the cables are buried under the EWI: more fcuked over.

Think outside the dish box.

Re run new cables from the new location up under the facia/soffit board and down into the house as required

Google satellite soffit mount. There are different types. You may see something suitable or it may give you some ideas.

Often when EWI is installed it reduces the depth of the soffit considerably though which might be a problem.

Yes. There is next to no soffit left.
I might look at mount at the top of the gable wall. One of the pics when googling soffit mount showed a dish mounted at that triangle.

That's what they did for me.

I wasn't very happy with the guy I used at the end. Nothing was a problem at the start and everything was an issue at the end

I was stung with the final paperwork being your hold on them, it's too much to hold for a snag, and you can't really stop it going through anyway.

If I was doing it again I'd have a 1000 euro payment sitting in there for snags as a reasonable hold on the contractor.


I would under no circumstances attempt this myself. If you mess it up the contractor will not standover it.

I'd get them back, possibly see if the seai can help to persuade them.

I'd imagine it would need to be cut out , grounds fixed to the wall and refinished

I have used easy drive fixings with conduit cut at 150mm long and the fixings were 200mm just mark it up hit the conduit in and than drill the holes and fix it up I've also used this method for lights

whosedaddy?

I guess sat dish is much more susceptible to dynamic wind forces than lights. I am tempted to try those fixings. But I take the points of contractor not standing over it. Mind you they claim to use such fixings, but just don't have those lengths.

In high winds it has the potential to cause significant damage to the chimney stack.

Hi all

recently had the house externally insulated and unfortunately I made the mistake of not having the timber plate fitted for the sat dish.

I’ve read through the above thread and wanted to check if the below product is my best bet? - I don’t have a chimney and installing on a fence / other area isn’t an option - has to be on the EWI

https://www.swifix.co.uk/product/satellite-fitting-plate/?attribute_pa_colour=white

does this product however actually prevent damage to the insulation if dust moves in high winds ? - don’t see the difference between this and just using long bolts to go back into concrete behind the insulation- appreciate the responses!

As previously mentioned - the dish does not have to be mounted high, I have set up several on the ground, mounted to a solid building block, or paving slab, as a base. If walls, and heights are an issue, and you can find a suitable ground space, I would use it.

Agree, our sat dish is mounted on the side of an old shed at just above head height. Low down it makes it much easier to align it but I would still keep it above head height as you don't want people walking into it. Firstly they might damage themselves and secondly you don't want to have to keep realigning the dish.

I’ve ran 8 shotgun cables to the proposed location back to a central location so I really don’t want to put in another location- also with small kids it’s not a good idea to have down low

I abandoned the original plan to fix through the external insulation. As we have sloped roof on side extension on same side of house where dish was , I got a rafter mounted dish holder. Worked out perfectly.. (but not option for everyone)
