Valve covers are a great way to insulate screwed valves. They fit perfectly around screwed valves and preventing heat loss and also protecting the valves from any damage, dirt and impurities. In our expert option, valve jackets are the best way to insulate screwed valves and here's why:

  • Thermal insulation: Valve jackets that we make here at Buy Insulation online are made with superior quality silicone coated glass fibre cloth. We make use of the same material for both internal and external valves, so you get the perfect finish every time you use valve covers from Buy Insulation Online. The silicone-coated glass cloth contains 25 or 50mm mineral wool or sager, both of which are known for their supreme insulation. 

In addition, valve covers have pull cords and velcro straps, which not only makes them easy to install but also ensures a snug fit around the valves, so there is no space for a heat loss. These valve jackets are hand-made to ensure quality and efficiency. 

  • Safer Workplace: Valve covers help protect your workforce from contact with the hot surface of the screwed valve, hence improving workplace safety. They also protect screwed valves from condensation or seating. As a result, water does not drip which prevents the formation of tiny water pools in the workplace, leading to accidental slips or mishaps. 
  • Easy Maintenance: Valve covers come with velcro straps and pull cords that ensure the s snug fit around screwed valves. Hence there are no gaps left in the insulation, resulting in a more energy-efficient building. This also reduces installation time by half. Plus valve covers are not lost or harmed in any way when each time you remove them from the valves, for maintenance, unlike hard, traditional insulation.
