|  How to Line a masonry fireplace 

If you are installing a new stove, 

stove surround or updating an 

existing one you must ensure that 

the wall lining in the fireplace is 

safe and doesn’t pose a fire risk.

You must ensure that the board 

has the legal certification that it 

can both:

•   Withstand temperatures of up 

to 1000°C; and

•   Is classified A1 non-combustible 

and will not catch fire or 

contribute to a fire

Promat PROMAFOUR® meets 

these criteria. It has been 

fully tested and classified to 

international fire standard, 

BS EN 13501-1 and carries 

a CE Mark which is the 

manufacturers declaration 

that PROMAFOUR® meets 

EU safety requirements.

Whilst there are other boards on 

the market which are classified 

A1 non-combustible, they are 

not designed to withstand the 

intense heat of a fireplace or the 

continuous ongoing strain that is 

unique in this environment.

Gypsum plasterboards – including 

the fire-rated pink boards – are 

combustible and should not be 

used for fireplaces.

In contrast, Promat PROMAFOUR® 

has been specifically designed 

to be used for the installation 

of a false chimney breast for an 

inset type fireplace and for walls 

surrounding free standing stoves. 

It will provide a clean, pre-

decorative finish for your fireplace 

and as it requires no plaster it will 

not crack under pressure from the 

most intense heat.
