2.13.14 A roof system using concrete on steel form deck shall be used for reinforced concrete buildings andconsidered where a load bearing masonry wall is provided.

2.13.15 Interior partitions shall be gypsum board on metal studs applying fire resistant drywall or moistureresistant drywall where required. Concrete block may be used as interior partitions where greater protection,occupancy separation, noise control or durability is required. Wood framing shall not be used for interior

partitions.

2.13.16 Insulation shall be provided for the entire building envelope. Exterior concrete block walls shall beinsulated with loose dry insulation poured into cores of block. If additional insulation is required, blanket or rigidinsulation shall be provided in furred space between exterior wall surface and interior drywall finish surface.

2.13.17 Rigid board type insulation shall be used in roof systems, along perimeter of foundation wall and inwalls not suitable for soft blanket type or loose fill.






2.13.18 The following minimum thermal resistance values are required where practical and in accordance with ASTM C518.

a. Ceilings (roof), R-30

b. Walls, R-17

c. Floors, R-11

2.13.19 When choosing doors and windows, the insulating value shall be considered.

2.14 Finishes

2.14.1 Buildings shall have non-slip or slip resistant finish on floor tiles.

2.14.2 All finishes shall be best suited to the industrial environment of a petrochemical process plant. Use offinish material that may be easily damaged is to be avoided.

2.14.3 Finish material with a choice of patterns or colors shall be reviewed by the Owner or his representativeprior to installation.

3. MATERIAL

3.1 Material selection shall be in accordance with A40-1M.
