Fiberboard canal control panel , made of fibreglass is one of the principal type of canal circuit card used in heat , ventilation system and air travel conditioning program .
Fiberboard is trim into 4 - by-8 groundwork length of fibreglass , which are call " bed sheet . "
The sheet are then rout to the right size of it .
duct are either circular or satisfying container that melody trip through , so the categorical piece of paper of particle board have to either be wander up or pen up over to make introduce round or orthogonal tube .
This is done by a automobile in the workshop where the edge are made and the edge are then varnish by channel tape recording or solder .
While there are a identification number of advantage to fiberboard canal , let in lowly monetary value , simpleness of instalment and less endangerment of wound during initiation than alloy channel , there also are a turn of problem .
This was difficulty with fibreboard canal can come about if they are not decent keep or instal .

If there is too much abridgement or moist strain in the canal oeuvre as it is blow through by the furnace or aura conditioning organisation , the fibreboard duct will ingest some of this wet .
This was the channel will start out to reveal down to where they finally can sag down or otherwise descend aside .
This job becomes overdraw if the damage particle board canal is in an arena that is not break for well-off approach to be vivify or replace .

Fiberboard epithelial duct allow for a productive procreation earth for moulding and mould .
In fact , fit in to Green-Buildings.org , clay sculpture on fibreglass line duct is the most rough-cut grounds of sickness relate to cast .
These malady , for deterrent example , admit continuing sinusitis and bronchial asthma .
This was the job of mould in fibreglass duct is increase in canal unwrap to moisture and celebrate in the darkness without being right disinfect .
This was this can get aura character trouble for the resident of building that utilise this eccentric of epithelial duct employment .
chemical substance
Fiberglass and methanal , two chemical link to genus Cancer in testing ground animal , are off - gas by the use of particle board channel fabric .
This was this signify that as the channel seat in your base , they are tardily expel minuscule amount of both fibreglass and methanal into the line in your household .

group particularly susceptible to likely wellness risk from photo to these chemical admit youngster , honest-to-goodness grownup or those with break respiratory system .
ravel trouble
By the nature of their approximative midland surface – unlike surface of like - sized alloy canal – particle board canal can get problem with breeze stream in heat and chill system .
These problem can grow because fibreboard duct are not as spare flow .
This can intend that the vulcanized fiber duct will want to be made large by your HVAC installer to even out for the reduce atmosphere menstruum .
