Nelson Firestop offers contractors a quick and easy way to maintain the integrity of fire-rated construction. CLK silicone is installed with a caulking gun, or by manually trowelling using a mason's trowel or putty knife. It is ideal for firestop penetrations and construction joints, such as around metallic pipes or conduits, and for floor-to-wall, floor-to-floor and head of wall applications. CLK is waterproof, smoke-proof and gas-proof.

Highly adhesive and simple to apply, this non-shrinking and non-toxic sealant maintains its flexibility and allows for movement or vibration, so it retains its sealing qualities even with expansion, contraction or other fluctuations. 

In addition to protecting and preventing the spread of fire, smoke, gases and water, CLK has been acoustically tested to demonstrate excellent noise reduction properties.
