Every high‑performance building has a secret: a membrane that makes the difference, between moisture intrusion and durability, between “built to code” and built to last.
That membrane is the CSL Si‑COAT® Air Barrier System, a family of silicone and hybrid coatings crafted to protect building envelopes in the harshest climates. From the roller‑grade polysiloxane to Tri‑Functional™ fluid‑applied coating, CSL Silicones Inc. delivers air-barrier chemistry engineered to perform in all weather conditions.
Why do builders, architects, and contractors choose CSL Air Barriers?
Because they deliver weatherproofing, breathability, UV resistance, crack-bridging flexibility, cold-weather cure, low-VOC and hybrid options.
These are not just coatings. They are air-barrier solutions built to seal and engineered to last.
CSL, powering the future of building protection.
