Valchrornat is the name for an MDF which is coloured throughout. It is manufactured in
a similar way excepting that after defibration of the woodfibres, a choice of one of sir,

Valchromat has been designed and developed, to a high level. Apart from being
moisture resistant, many of its physical and visual characteristics well outstrip those of
ordinary f brobourds. The physical and chemical proportios conform both to CEN and
EMB norms for MDF
At present Valchrornat is available in a choice of six Colours and seven thicknesises. The
colour control of the product is based on, and conforms to. the data base listed by
CIELAB. Light resistance tests conform to those laid down in BS1006. The board is
moisture resistant. and with a formaldehyde content of less than 9mg/100g.
a therefore Class , -
Valchrornat has a high melamine content in its makeup, which acts
as a lubricant during machining, and helps to ensure an cdgo
which requires only n minimum amount of sanding to achieve
a high standard of finish.

RE. Construction Classification at Music
Dear Dan,
I appreciate your bringing the Construction Classification of the Music area to our attention earlier
this week. After returning to my office, I discussed the question with Keith Johnson, the Project
Manager on this job. He concurred that we had intended this area to be Type VN and not Type V -1
hr. as shown. It actually is shown correctly as Type VN on a subsequent drawing labeled
"Fireproofing Plan." The actual area of 7,677 SF is lower than the 9,100 SF allowable for a Type
VN "E" occupancy, thus giving us the ability to classify this area as such.
I hope this letter clarifies this mistake to your satisfaction, please call if you have any questions or
comments.
