door swings towards this wall. This will now match the requirements in the IBC. <br />5. New Section R310.5 clarifies that when an emergency escape window (for bedroom or <br />sleeping room) is located under a deck or porch the window shall be able to be fully <br />opened and a path not less than 36" high shall be provided to a yard or court. This is a life <br />safety issue. <br />6. Section R311.4.3 was changed to clarify requirements for landings at exterior doors. <br />The major change in this section is that door landing slopes are now regulated. They <br />will need to have a slope that does not exceed 2%. This applies to any exterior door. <br />7. Section R319.1.5 now requires that glued-laminated timbers exposed to the weather <br />and not properly protected by a roof, eave, or similar covering be pressure treated with <br />preservative, or be manufactured from naturally durable or preservative-treated wood. <br />8. Section R323 was added to give guidance on requirements for elevators and platform <br />lifts. This gives us direction to ASME A17-1(the elevator code). <br />9. Section R408.3 now gives direction for "unvented" craw) spaces. <br />10. Section R613.2 now requires that where the opening of an operable window is located <br />more than 72 inches above the finished grade or surface below, the lowest part of the <br />clear opening of the window shall be a minimum of 24 inches above the finished floor <br />of the room in which the window is located. Glazing between the floor and 24 inches <br />shall be fixed or have openings through which a 4 inch diameter sphere cannot pass. <br />This will also apply to windows that are directly above a basement window well. <br />11. Section R702.4.2 now requires the use of cement, fiber cement, or glass mat gypsum <br />backers behind wall tile in tub and shower areas and behind wall panels in shower <br />areas. Moisture resistant drywall (green board) is no longer acceptable in these areas. <br />12. Section R703.4 now requires that, in areas where the basic wind speed is 110 <br />mph or higher, attachment of exterior siding meet the component and cladding <br />loads specified in Table R301.2(2), adjusted for height and exposure in <br />accordance with Table R301.2(3). The contractor shall verify the fastening <br />requirements with the manufacturer for all wall coverings. This will not affect the City of <br />Paris, as we are not in the areas addressed in Table R301.2(2). <br />13. Table 703.4 now requires approved water resistive barriers behind all siding materials. <br />14. Chapter 11(Energy Efficiency) has been revised in its entirety. Please also see the <br />handout for the 2006 Energy Codes. One of the bigger changes is that Table N1102.1 <br />will require the exterior wall insulation to be R-19 or R-13 with an R-5 insulated <br />sheathing covering the exterior. There is an exception that allows the R-5 to be <br />reduced to R-2 if structural sheathing covers more than 25% of the exterior. This will <br />effectively not allow a 2 X 4 wall with the typical R-13 unless there is additional R-2 or <br />143 <br />
