Cavity Wall Insulation

Folk keep telling me it's free.

 

Anyone had it done and does it work?

Its the new PPI.

 

Have you had cavity wall isulation? Is your house now fucking riddled with damp?

 

Think Smiffs or BCG would be best to advise though.

I concur. I have it and being removed in spring, the gable wall should defo never had it in the first place.

No good, causes damp.Wish we hadn't had ours done.

Right then.

 

I'll just turn the heating up :D

Put another jumper on.

There's a cavity for a reason!

stick some that stuff in the loft 

I had it done FOC years ago.

 

Saved a fortune on my heating bill.

I've had it done on a free. I think I'm warner. I'm not colder.

Sick to death of people knocking on the door offering it FOC

 

Always refused thinking there's a catch

 

Apart from damp, mentioned above, what are the problems and why are people offering it to me free? How does a company benefit by doing it free?

Supposedly government grant but we are now getting door knockers claiming it is installed incorrectly and they will help us to claim

We've had it done, never noticed the house being any warmer or a reduction in our gas bills tbh.

My architect seems to recommend it

 

He’s had no problems with his

 

Still very wary though

Just Say No.

We are thinking of rendering the whole house in K rend which I believe is silicon based and water repellent (to an extent)

 

Would this then reduce the risk of cavity wall insulation getting damp?

Don't do it.

Something like a phenomenon - baby!

K rend is good but you need a good dry spell when it's applied, any rain/moisture on it will RUIN it. Also the colour pigments fade quite a bit over time.

I wouldn’t expect it to last forever, i’m assuming it’s a simple paint job every few years rather than a full re render?

Should be OK to paint over with a normal masonry paint, but because of the silicone content of the k rend I would seek advice.

Is it compulsory for renderers to coat windows and frames with bastard render every time they apply it? The fuckers get more on the window than on the wall.

 

Always wondered why new windows can't go in after the render has taken place??

cause then they will get it on the carpets 

I'm not an expert on this as it's not really structural but..

 

The cavity is the last line of defence if water gets in. It's bloody difficult to get buildings 100% watertight, the cavity will redirect water via the tray at the bottom.

 

Now if you fill the cavity with insulation, water that would otherwise leave the building has a pathway inside.

 

So good or bad idea, it depends.

No better insulator than an air gap. Don't be sucked in.
