A student union has called for urgent safety checks on university accommodation as firefighters investigate the effect of cladding on a blaze which destroyed a block of flats in Bolton.
Students were forced to flee as flames tore through The Cube on Friday.
The National Unions of Students (NUS) has urged the government to audit all cladding that could pose a safety risk.
The government said building owners "must ensure residents are safe".
University of Bolton students were evacuated from the accommodation when the fire broke out at about 20:30 GMT.
About 220 students are set to be re-housed and more than £10,000 has been raised through a crowdfunding appeal to help those who have been affected.
Greater Manchester Fire and Rescue Service (GMFRS) is investigating what role the cladding played in the fire.
It inspected the building in 2017 following the fire at Grenfell Tower in which 72 people died.
It has since been confirmed the high-pressure laminate (HPL) cladding used at The Cube is not the same as the now-banned aluminium composite material (ACM) at Grenfell, Salford mayor Paul Dennett said.
But the Fire Brigades Union warned HPL cladding was "more widespread" than the material found on Grenfell Tower.
NUS vice-president (welfare) Eva Crossan Jory told BBC Radio 4: "We are aware that there are quite a few student accommodation buildings that have similar cladding.
"We definitely think more need to be done to address the fact that this sort of cladding was allowed to be put on those buildings in the first place. We are very worried.
"Are corners being cut and is students' welfare being put in jeopardy because of costs?"
She added: "We want to see immediate action from government to audit all cladding that could be causing fire-safety issues and remove it immediately if it is likely to exacerbate a fire.
"This should perhaps also take into account buildings that fall below the 18m 'high-rise' definition."
Matt Wrack, general secretary of the FBU said: "There are different forms of cladding that are also flammable and this particular one appears to be HPL.
"Industry reports are that this is more widespread than ACM so we have a much wider problem."
He said there needs to be a "clear plan to remove dangerous cladding".
Labour's Shadow Housing Minister has also written to Housing Secretary Robert Jenrick outlining 12 urgent questions on building safety.
Sarah Jones said: "Two and a half years after Grenfell it simply beggars belief that the government has left eight in ten buildings covered in the same deadly cladding.
"And it is equally astounding that you neither know how many other types of deadly cladding exist, nor how many buildings are wrapped in it."
A government spokesman said it had "repeatedly made it clear building owners must by law ensure their residents are safe in their homes".
The government said: "We have also provided councils with funding so they can find out the type of cladding on all high-rise buildings in the country, and have tested a number of non-ACM materials, including high pressure laminates, to assess whether any further action is necessary,"
