NEWTHERM® P is
a rigid board but edges and corners should
be protected where impact damage may occur.
The large range of thickness available allows selection of the most
economical board to meet given periods of fire resistance.
All board sizes are based on metric equivalents of imperial
dimensions rounded to the nearest 5mm.
Non-standard sizes available to order. Standard sizes and board
tolerances are shown above.
