Safety & Silence
The demising walls separating individual suites at The Westerly will be built to a standard far exceeding what is required by current building codes – constructed to not only provide residents with exceptional approx. 63 STC (Sound Transmission Class)* rating for quiet and comfort, but also giving peace of mind knowing that the walls are rated to provide at least 1 hour of fire protection.
WALL AND FLOOR CROSS SECTION
a, e – 2 layers 5/8” type x drywall
b, d – 2 1/2” metal studs with 2 1/2” insulation
c – 1” Air space
f – Engineered hardwood floating flooring on silent step acoustical flooring underlayment
g – 8” Thick reinforced concrete slab
STC for walls between suites at the Westerly = approx. 63
Code requirement STC = 50
*The STC scale was developed to measure the airborne sound transmission through a demising wall. An STC of 65 is designed to reduce sound transmission to the maximum extent possible – it is the “gold standard”. Most demising walls are in the range of STC 40-45.
