Our Patented Valve Covers

Can Save You Substantial Labor Costs

Our patented design makes not only the insulation of valves easier, it saves untold labor and expense. If properly installed and removed, the Corick Valve Cover may never have to be replaced.

  • No more expensive call outs to contractors to replace insulation after valves are serviced.
  • No more labor wasted insulating valves in the traditional manner, only to have them damaged, requiring replacement before the end of the job.
  • No more material waste or clean-up. Corick Valve Covers come virtually ready to install.

Tech Specs


Corick Removable / Reusable Insulation Valve Covers are specially designed for use on Chill Water, Heating Hot Water, and Domestic Water valves and equipment. When properly installed Corick Removable / Reusable Insulation Valve Covers effectively retard heat gain, and prevent condensation or frost formation on cold equipment. They also effectively retard heat loss when used on hot equipment.

Flame and Smoke Ratings
  • Elastomeric thermal insulations in 1/2″ and 1″ thickness
  • Flame Spread - 25 or less
  • Smoke Density - 50 or less
Moisture Resistance

Closed cell structure is in it's self a vapor barrier, but under continuous conditions of high humidity (tropical conditions) additional vapor barrier protection is recommended.
