Hello joed-ga,
You have nothing to fear from the ?greylite insulite sheathing? in
your ceiling. Various forms of ?insulate? have been around for almost
100 years and I?ve identified several current manufacturers. The term
?insulite? seems to have evolved into a generic term (like Kleenex or
Xerox) although there are several references to it being trademarked
or registered. There is some discussion of litigation between the
Insulite Company and Masonite Corporation in a 1942 Supreme Court case
United States vs. Masonite Corporation. Insulite products through the
years have had various compositions all of which had highly heatproof
qualities. None of them are hazardous. I?ve included links to several
of these.
I?ve included a section on historical references to insulite as well
as to a variety of entirely different products that also use this
name.
I have not been able to find any reference to ?greylite? as a company
name. This term is currently used to describe a specific type of
industrial glass.
I hope you can put your mind at rest about the safety of the insulite
you?ve found. Please don?t hesitate to ask for clarification on any of
this.
Wishing you well.

Question: Are all fire resistant files alike?
One of the biggest differences in a Schwab file compared to others is
Insulite?, the most effective insulation in the industry. Insulite
provides maximum protection with thinner walls and less weight than
competitors' insulation. Because Insulite does not contain free water
it will not dry out and lose its ability to provide fire protection
over a period of time as compared to competitor?s files utilizing
gypsum as an insulating material. Gypsum being the same material as
that used in drywall, makes it vulnerable to water and decomposition.

INSULITE ? HISTORICAL REFERENCES

U.S. Supreme Court
UNITED STATES v. MASONITE CORPORATION, 316 U.S. 265 (1942)
316 U.S. 265
UNITED STATES v. MASONITE CORPORATION et al.
No. 723.
Argued April 9, 1942.
Decided May 11, 1942.
Insulite, a manufacturer of insulation board, began producing
hardboard in 1930. Its production rose from about 4,500,000 square
feet in 1932 to about 9,000,000 square feet in 1933 and amounted to
over 7,000,000 square feet annually in 1934 and 1935.

Probably no mill in Ontario utilizes a higher percentage of poplar
than does the mill at Fort Frances. This is made possible by the
integration of paper manufacturing at Fort Frances with the production
of "Insulite" building products fabricated basically from wood fibre
at the sister mill in International Falls, Minnesota, just across the
international Rainy River.

Acoustics by JW Mooney
Between 1920 and 1930, considerable work was done to develop other
sound absorbing materials. This included 1) compressed wood fiber
slabs sold under tradenames such as Acousti-Celotex and Insulite
Acoustile, 2) compressed straw such as Thatchboard, 3) porous plaster
which included Sabinite and Calacoustic, 4) felts and wools of
asbestos, hair, wood fiber and mineral fiber, 5) Eel grass quilts and
building blankets, 6) Slag-wool in wire netting called "Slag-bestos",
7) Balsam wood fiber in wire netting, and 8) Rock Wool with a
perforated metal facing.

The gym was thought of as state-of-the-art.
"The ceiling is covered with Insulite and Masonite in attractive
panels, and the building is lighted by 54 recessed ceiling lights,
each with a potential of 500 watts, making it the best lighted
gymnasium and playing court in the state of Kansas," the program
reads.

The Insulite Housing Group was a co-operative that used a combination
traditional work culture and innovative materials and techniques to
build 15 slag houses in Sydney, Nova Scotia, between 1950 and 1954.
This group built houses using an innovative building technology
utilizing slag from the Sydney steel plant.

Insulite Micro
Insulite Micro is made of micro-thin fibres, that are finer than a
filament of silk. Through a pattern of micro fine fibres, which create
many microscopic air pockets, this insulation has a very high weight
to warmth ration, protecting you from the cold. With its excellent
draping qualities it complements the modern fibrics used in the outer
shell and inner lining of the sleeping bag, to give an un rivalled
snugness. The microfilament yarns are treated to make them
non-allergenic, durable, and easily cleaned.
Insulite
A specially developed filling by Vango, it traps more air to provide
up to 20% more warmth than solid fibre insulation. Through their
hollow, siliconised and spiralled fibres it retains insulative quality
even when wet, is easy care, durable, machine washable and
non-allergenic. It maintains shape and insulative qualities even after
repeated cleaning.
