Claim 5

The room construction of claim 1, wherein all said panels are stepped at their coves above the room floor to enable a floor screed to finish flush with the horizontal face of the cover and are stepped forward from the vertical faces of the cove to allow a flooring system to be applied continuously up the coved surfaces to end flush with the wall surface of the panels.

Claim 6

The room construction claimed in claim 1, wherein at least one of said panels having a double wall construction have one wall formed with a plurality of apertures disposed thereover from said lower region upwards for enabling horizontal air flow into the panels to take place across the room construction.

Claim 7

The room construction according to claim 1, wherein all said panels are formed at ceiling level thereon with an integral coving extending thereacross on which ceiling tiles rest.

Claim 8

The room construction according to claim 2, wherein said corner pieces and all said panels are stepped at their coves above the base floor to enable a floor screed to finish flush with the horizontal face of the cove and are stepped forward from the vertical faces of the cove to allow a flooring system to be applied continuously up the coved surfaces to end flush with the wall surface of the panels.

Claim 9

The room construction according to claim 1 wherein all said panels are formed of glass reinforced plastics material.

Claim 10

The room construction claimed in claim 5, wherein all said panels are formed of glass reinforced plastics material.

Claim 11

The room construction according to claim 1 and which additionally includes at one or more panel positions a door.

Claim 12

A room construction for maintaining a sterile environment comprising a floor construction, a plurality of ceiling panels a plurality of wall panels having a double wall construction with an air space existing between opposite walls thereof, and means connecting the wall panels together at upstanding marginal regions thereof, the wall panels including thereamong a plurality of panels each having in a lower region thereof at least one aperture thereinto from the room interior communicating the room interior with the interior of the panels and means in an upper region thereof for communicating the interiors of the respective panels with extraction ducts, the wall panels being coved at their base edges to provide a rounded surface transition from wall to floor within the room, which room construction comprises as said wall panels, wall panels moulded as a single element from synthetic plastics material in a double skin construction with opposite walls joined at their upstanding edges, said wall panel connecting means being formed at connections between in-line panels as paired single walled moulded panels of synthetic plastics material having coving at their base edges connected to the said wall panels on either side thereof to provide a surface continuous with that of the panels which they join at substantially all positions over the height thereof at least up to ceiling level and to define therebetween service ducts for supply of services to either side of the wall comprised thereby, and said floor construction being formed above said apertures as a perforated false floor positioned over a lower floor, whereby vertical airflow from ceiling to floor is able to take place within a room defined by the room construction, additional coving being moulded on all said panels and providing a rounded transition from the false floor to said panels.

Claim 13

A room construction for maintaining a sterile environment comprising a floor construction, a plurality of ceiling panels a plurality of wall panels having a double wall construction with an air space existing between opposite walls thereof, and means connecting the wall panels together at upstanding marginal regions thereof, the wall panels including thereamong a plurality of panels each having in a lower region thereof at least one aperture thereinto from the room interior communicating the room interior with the interior of the panels and means in an upper region thereof for communicating the interiors of the respective panels with extraction ducts, the wall panels being coved at their base edges to provide a rounded surface transition from wall to floor within the room, which room construction comprises as said wall panels, wall panels moulded as a single element from synthetic plastics material in a double skin construction with opposite walls joined at their upstanding edges, said wall panel connecting means being formed at connections between in-line panels as paired single walled moulded panels of synthetic plastics material having coving at their base edges connected to the said wall panels on either side thereof to provide a surface continuous with that of the panels which they join at substantially all positions over the height thereof at least up to ceiling level and to define therebetween service ducts for supply of services to either side of the wall comprised thereby, and said floor construction being formed above said apertures as a perforated false floor positioned over a lower floor, whereby vertical airflow from ceiling to floor is able to take place within a room defined by the room construction, additional coving being moulded on all said panels and providing a rounded transition from the false floor to said panels.

Claim 14

The room construction according to claim 11, wherein all said panels are stepped at their coves above the false floor to enable a floor screed to finish flush with the horizontal face of the cover and are stepped forward from the vertical faces of the cove to allow a flooring system to be applied continuously up to the coved surface to end flush with the wall surface of the panels.

Claim 15

The room construction according to claim 11, wherein all said panels are formed of glass fibre reinforced plastics material.
