Thank u very informative

Weird video switching to a human

You are full of it!!!!!!!

Explain with video then all body will understand

The Building Surveyor will inform you that it has to be removed. Happened to me, £4.000+ installation then this year another £3.200 to have it removed just so i could sell my house.

Spray foam insulation is awful. I could show you pictures of roof jobs where the foam has ruined the timber. Rockwool is far better.

Very insightful ❤

Helpful video but you did not answer how much one should expect to pay. What is the point?

Thank you for the information on the difference. Due to flammable and other factors it is not a choice for my home. Perhaps a shed or garage.

Stange video not looking at cam and reading?! Had to switch

Nice video, but it is a little bit complicated. I assume that you an iprove the video when you structure it and include short summaries or bullet points. Keep up your good work while educating others.

First of all, there are many ways to utilize spray foam in construction....your example is not the standard nor is it required. As with any construction material, spray foam can and should be designed into an assembly by qualified/certified experts....why you are focusing in on a very widely used product like spray foam is questionable.....and spray foam can meet fire code requirements in almost every case.....if your goal is quality construction, discuss the pitfalls of fiberglass insulation that commonly causes building failures......

What is the boundary?

Why's he not looking at the camera. It's kinda distracting

My buyers want to do survey level 2 with my 5 years old house just before exchange the contract which is a bit suspicious , they were here 3 times to view property, so I believe they expect that survey report will give them chance to negotiate price

Good info, thanks

I am a leaseholder. Bought my flat 5 years ago, when I was 23. Quiet young and didnt realise I was making a mistake by refurbishing ;( ! What should I do now? I changed the carpet to hardwood flooring. I chabged the bathroom from Tub to Shower. And I removed the wall that separates the Kitchen and the living room, making a open space. The flat looks beautiful now, and definetly has more value. But certainly that was a mistake, without getting the freeholder permission. I am so scared and upset. Can you give me some advice on what to do please?

So, the practical solution is to use spray foam on walls, and rigid foam or fiberglass beneath the roof?

It dosnt seem to be a problem in ireland? They say here dont spray to the felt and put in a 2 inch card. And there would always be a breeze coming between felt and foam that wouod dry and condenstation

Hi I am a truss designer, in my service I provide truss layout and design. also provide quantity takeoff for construction jobs i/c; MEP. Thank you

I would think if you want to avoid lender issues ( mortgage) don't spray foam your attic. Also, you won't know if you have water issues until a lot of damage has been done. Just my opinion. I think the mortgage issue seems to be in the UK

Imagine him speaking like that about women. "Crazy women are a problem and can create many serious problems." Well, that certainly is true, and all the sane women out there agree with that. But when only crazy women are being spoken of, the problems they cause get hung on ALL women. Other countries have long histories with spray foam that are positive. Because it is easy to find responsible information on this subject today, it's alarming that any institutions in the U.K. would dare to push bad policies that are based on false claims.

No sound for half the video

Given the manipulative cold-callers I get, using scare tactics and telling lies, I doubt very much that the sprayers are 'well intended'.

I've never had a problem selling homes with spray foam insulation, nor have I heard of lenders rejecting a spray foam insulated home in my area (zone 6a). I've had fiberglass insulated homes that had mold issues due to the fact that most batt insulators don't take the time to get the batts into very tight spaces at corners or around windows or in stud spaces that are way less than the width of the batts. By smashing batt insulation into small spaces, the insulation value drops due to compression and you can get condensation. Interior plastic sheet vapor barriers get punctured with drywall screws, poor insulating detail around receptacles and homeowners punching nails through to hang stuff on walls. Without insulation covering 100% of the sheathing and a proper continuous vapor barrier, condensation will form in colder climates. With spray foam, the foam expands into tight areas, so you are less likely to have any condensation issues and no vapor barrier is used because spray foam is the vapor barrier. Closed cell spray foam also adds rigidity to walls. We gutted a 50 year old home and re-insulated with closed cell and there was no more wall creaking when it was windy. Spray foam is superior to other insulations for filling small gaps and R-value per inch. Most new homes in my area have been using closed cell spray foam for many years with zero issues. The best practice, IMO, is to use Zip-R exterior insulated sheathing with the correct R-value for your zone. When the sheathing seams are properly sealed with Zip tape or liquid flash, the building envelope is airtight and watertight with no need for window bucks, furring strips or a WRB, as you'd need with XPS or EPS over sheathing. Not all homes should use spray foam. Very old homes need their wall cavities to breathe due to air leaking cladding. Vapor permeable batts are a safer choice. If your roof leaks, it's most likely due to having an old roof which needs replacing and that neglect is on the homeowner. When re-roofing, I'd rather need to replace some roof sheathing and maybe some roof truss repair than replacing rotting wall studs, hardwood floors or personal property if the roof leaks with batt insulation.

Its well or better then well. I have used rockwool invented in USA i USA in 1953 or something. Here You have the rain and will will repair Your roof or walls before its too late. Nice KZbin

Good advice is offered here in that tracking down the actual cause of damp requires a whole house approach, that the causes may be multiple rather than singular, and that sales based damp-proofers are rarely the best people to seek advice from. I do think it important to add however that not all Chartered Surveyors have expertise in the diagnosis of damp, as many purchasers who have obtained Home Buyer and Building Survey reports will testify. Always worth asking to view previous reports of similar properties so you know what to expect.

Good information. Thanks

Can the building owner get access to the schedule of condition including photos undertaken on the adjoining property?

I like the cask behind

Interesting video, but losing the voice several times
