Some sort of insulated pipe with a valve, going into a reservoir or overflow tank.
During my lunchbreak at work, I went for a walk with one of my colleagues. We strolled across the Business Park Apeldoorn terrain, which used to house companies such as TNO and IT firms with on-premise datacenter/colocation.
Most of the buildings are empty and abandoned now. Large transformer arrays, huge chimneys, warning signs and leftover bits of technology are some of the silent witnesses.
It seems this well insulated wall has a life of it's own. Day to day it changes, moves and shifts...
View of vermiculite insulation in residential attic space. Subsequent laboratory testing indicated this material contained 2-5% amphibole asbestos.
This is by far the best insulation for a true cathedral ceiling. With closed cell foam, there is no need to ventilate the soffits or roof. There will never be condensation, mold, or ice dams in this attic.
We had to take pictures at night, after work, because the crew was making really good progress. Things moved quickly.
Since the house was already gutted back to the bare studs, it was the perfect opportunity to re-insulate with modern insulation.
Two-image comparison in side-by-side format showing a pipe system as uninsulated and then insulated with asbestos materials "before & after"; from a 1950's-era vintage asbestos industry publication.
Added in red are labels indicating "After & Before" in reference to a reverse scenario as it might apply to asbestos abatement today, after removing the asbestos insulation.
Area of exposed insulation on large diameter pipe associated with an industrial boiler. The insulation was tested and found not to contain asbestos. Senior maintenance personnel indicated the original asbestos insulation was abated in the past and replaced with this newer material. Pre-formed notches in the newer insulation appear to be able to allow it to bend around curved mechanical equipment.
With the temperature below zero, I'm very glad to have something to keep this drafty window covered up.
Thanks to Ed Vielmetti for the info a while back:
Closed cell insulation in the cathedral ceiling with cellulose in knee walls. The cellulose was used as a cost saving measure and chosen by our client. We always recommend foam in a walls & ceilings.

Close-up view of the asbestos insulation material packed on the inside portion of the Kewanee boiler door. The soft and crumbly insulation was tested and found to contain approx. 10% chrysotile asbestos along with a mixture of vermiculite flakes as well.
An uncommon application of an asbestos material: thick asbestos paper insulation on PVC pipe. PVC pipe tended to be installed in later era construction and typically appears uninsulated or usually may be seen with non-asbestos fiberglass or foam-rubber insulating materials installed on it.
However, in this case, reportedly an older supply of asbestos paper was found tucked away in forgotten basement storage areas and was installed on "newer" building components by building maintenance staff.

My sister, who used to collect these types of insulators, went nuts when I showed her this photograph.
Night, 3/4 moon, 100 second exposure with mini-maglite supplementing the insulators.
Closer-up image of the vintage Air-O-Cel Insulation Board material showing three layers: 2 outer asphalted paper layers with inner brown corrugated cardboard sandwiched between. Interestingly enough, this particular insulation material was analyzed and found not to contain asbestos.
Research into Air-O-Cel's patent information seems to support laboratory testing results that asbestos was not specifically indicated as a constituent in the product's construction. Although a subjective observation, if you think about it, the brown color of the corrugated middle layer does not appear as the typical grey color of vintage asbestos-containing corrugated papers.
However, a few aspects about the insulation material seem almost contradictory to its non-ACM status; primarily, such as the product's name "Air-O-Cel" being very similar to another well known corrugated paper insulation product that DID contain asbestos, known as "Air-Cell". It doesn't help either that asbestos manufacturers actually did make an asphalted asbestos Air-Cell product practically identical to this "Air-O-Cel" insulation board, as well.
Further, "Air-O-Cel" patent information indicates it was patented in 1933, well within the era of significant asbestos manufacturing and usage.
This asphalted and corrugated insulation material is older (from late 1930's house), its name resembles a once popular asbestos insulation (Air-Cell), and even looks like a certain type of asbestos insulation. Despite the fact a suspect material might not contain asbestos may help demonstrate why we must still inspect, sample, and analyze to test the plethora of suspect asbestos materials out there, to identify asbestos materials, take appropriate actions, and ultimately help keep us safer in the long run.

(I would hate to see their heating bill.)
Basic overview of a small Kewanee boiler door with the manufacturer's name and part number on one side and asbestos insulation & gasket on the other; approx. 4-ft. across diameter and weighed about 75-lbs.
Insulation in the ceiling! For whatever reason, the City & our gas provider consider this insulating the floor--but I consider it insulating the basement ceiling. You say tomato, I say tomato...just stuff the fiberglass into the beams, okay?
