Insulating Material

[Bryn23]

Don,t laugh Bryn mine hasn,t been cleaned since i got it about 5 years ago ! I use it at least once a week and never have any problems as they are pretty air tight as the breather hole gets blocked any way . On occasions I take the front nozzle off to clear but thats it .

Wow, I'm really surprised it's still working, we have spray quality control issues if they aren't cleaned, need a fine even spray.

One other problem we had was the gun contacting itself to the pot, if left overnight, still the guns can be brought quite cheap now and they are almost a universal design, and its not like you are spraying 2 pack with them and aiming for a paint finish

I will jump in here with 50 years of experience behind me with car interiors , as you would have seen in both my links I have used the same product for that same 50 years almost . Now it is Underlay 900 GSM it Won't absorb moisture Won't rot or smell 'damp' Easy to cut and work with Good acoustic and comfort performance . I think from memory its at least half the price of what Stage 2 is for a start for the same amount of meterage . Its not so much how good the product is its the attention to detail in application , the better its fitted corectly the better it works .
In all the vans I have done they are as quiet as most cars inside with very little road noise or other noise intrusions after installation . If you look at both jobs there are different photos taken at different times in one you can see lots of alloy tape covering up all the holes along the sides also same photos at the bottom of the body cavities there are rolled up 25 mm foam pieces which are blocking noise coming up from the road along the rockers and wheel arches . Inside the pillars where no acess was possible expander foam was used . You can buy the 900 GSM Underlay from your Nolans UDA outlet in Melbourne .

Sunny43.5, is this similar to the Underlay 900GSM you mention from Nolans; Underlay 900 GSM | The Nolan Group

Below is a picture of a 2015 Ford Mondeo Titanium Wagon that I once owned (the underlay was OEM on the Wagon, not the hatch however).
I am trying to find the "underlay" that Ford uses to do a similar thing to my ŠKODA Superb.

Any thoughts / suggestions?

Sunny43.5, the Sound Deadener you used in the following VW T5; Insulating T5 "Another wet weekend and someone is getting a makeover"

What is the material that you used for the Door Trims vs the Load Bay and Wheel Arches (this product looks close to the Ford Underlay I asked about above).

[Sunny43.5]

I used the same material for doors floor walls almost every where , the only other material used were foam "skins "which are the top and bottom of a block of foam . They vary in thickness but are real good to stuff into pillars and along the inside of the sill areas. You could also use an old 4 inch foam mattress and cut strips of that as well or blocks for the pillars .

Great info. I’ll be looking at insulating my 2006 multivan comfortline as we will be turning it into a camper. Was there any reason why you chose the 900gsm underlay over the van liner? How much am I looking at to stuff as much in the multivan as possible? Roof, doors, anywhere else? Cheers

Ok a couple of things price is a big factor the Van Liner is according to their website $130 per 5 metre roll so the roll is only 1 metre wide which works out at $26 per square metre . The 900 GSM is 1.8 metres wide on a continuous roll so you can buy whatever length you need , it was last time around $20 per linear metre which works out at around $16 per square metre so it is around $10 a square metre cheaper . To do a complete interior which is roof side walls wheel arches front doors tailgate and side door will use approx 30 square metres of either product , just remember the 900 is 1.8 metres wide so you would only need about 15 metres on the roll .
I suppose I am biased as the 900GSM is pretty well the same specs as most car makers use and I have used it for nearly 40 plus years since it first came out . Ok you would need a glue gun and compressor to do the job but if you are lining the van side walls and floor etc with some sort of hull liner flex and then commercial carpet on the floor you will need a compressor anyway , the only advantage of the Van Liner is that its self-adhesive which can be difficult to get into tight spaces as it tends to stick before getting it where you want it ! Check out the link I posted earlier to see some more photos of where I glued the material too .

Thanks heaps for the info! We will be keeping the multivan as functional as possible so we will be keeping the interior panels, carpet, track system, two captains chairs etc. So I’m basically looking for the best way to insulate the van so that’s it’s comfortable to camp in. I figure it’s a little bit different to say fitting a transporter out as you have a large base template to work with. That was the original plan but then we stumbled across a great deal on the multivan so we jumped on it. So do you think by insulating the roof, side doors, front doors and tailgate in the 900gsm underlay be enough to make the van comfortable in the hot QLD sun? ����

In our van we often camp at a Moto Cross Park west of Brisbane and it can get very hot there during the summer period , on occasions I will have a snooze in the back and its quite comfortable even in the sun . I am sure it does work quite well as you dont feel the radiated heat from inside the roof .
