Hi Guys - I suppose I have to ask now but what are these fire stop top and bottom?
How can this be checked?
I know an architect was involved back when this was built but that probably count for very little....

Here is the text from a supplier

Fix metal frame system/timber battens to the wall in accordance with the manufacturer’s instructions. Sections should be placed around all wall edges and around openings and services.

and
Fire Stops
An important factor when drylining a wall is to provide fire stops along the top and bottom of each board and around all openings (doors, windows, etc). These are provided by the battens and prevent fire penetrating behind the insulation layer. This also helps to prevent thermal looping, leading to an overall improved U-Value for the wall element.

Perfect. But he does not have metal struts or battens.

he has the good old tried and trusted (:eek: never to be seen again) dot'n'dab.

What should have been an asset to building construction methods at the time, was high strength adhesives, and silicone mastic, and expanding foam.

This introduction to the building trade threw proper construction methods clean out the window into the next county.

And along came the " have silicon gun" will travel brigade. Thats stuck, filled, and smooth finished every item in a house, quicker than you can say handy Andy.

And not much has changed at all.

I passed a local building site today, that has stack towered multiple pallets to wall plate height, in order to stand on them to roof an extension.

And numerous council vehicles passing these al day long, and no visit from anybody.

Dont get me started

Did you ever get this resolved? I had EWL fitted new windows triple glazed and made sure they put in extra insulation into any gaps before fitting. I have hollow block too with a very thin layer of insulated plasterboard but house is still freezing . Thanks.

Your likely issue is air tightness (or lack thereof) rather than insulation related.

Did anyone mention air tightness at all or was the house tested for this? (You might have been told that the ewi and new windows would deal with air tightness … they don't)

MicktheMan

And, if true, you are not the first to find this out the hard way and certainly not the last.

No air tightness was never mentioned. They didn't remove the sofit so I'm hoping that maybe the issue is that the EWI doesn't meet with the attic insulation. They are coming back to look fingers crossed . Disgrace to pay all that money and be no better off . Thanks.

MicktheMan

Not going past the soffit with ewi is NOT the reason for the freezing house … it does, however, result in increased risk of damp and mould inside high up on the wall.

Disgraceful is a mild way of putting it. In my book it's criminal what's going on and allowed to go on by the seAi who are primarily responsible for this mess. Authority my ass.
