Optimal Environmental Control: Dockstar Industrial’s PermaTech Seals and Shelters
The loading dock is a gateway to your facility, but without proper sealing, it can also be a major source of energy loss, compromised security, and environmental infiltration. At Dockstar Industrial, we partner with Perma Tech, Inc., a trusted name in the industry since 1984, to provide top-of-the-line dock seals and shelters that create a secure, energy-efficient, and protected environment at your loading bays.
What Does PermaTech Do?
Perma Tech specializes in designing and manufacturing custom-engineered loading dock seals and shelters that create a tight, consistent seal between your facility and the back of a truck or trailer. Their approach is rooted in understanding that “one size does not fit all” when it comes to loading dock environments. They focus on delivering durable, high-performance solutions that reduce energy costs, protect products, enhance safety, and improve overall operational efficiency by effectively sealing off the dock opening from external elements.

Our Perma Tech Product Offerings: Tailored Solutions for Every Dock
Dockstar Industrial offers a comprehensive range of Perma Tech dock seals and shelters, custom-designed to meet your specific needs and facility requirements:
- Dock Seals: These are foam-filled compression units covered with durable fabric, designed to create a tight, energy-efficient seal when a truck backs squarely against them.
- Original Dock Seals: Traditional foam pad seals, ideal for uniform truck sizes and standard dock parameters.
- Weather Shield Series Dock Seals: Enhanced designs for superior weather protection and durability.
- FIREguard Dock Seals: Specialty seals designed for fire safety and compliance.
- Protector Dock Seals: Offer extra security and robust protection from wear and tear.
- Reducer Dock Seals & Adjustable Seals: Solutions for accommodating varying truck heights and unique dock configurations.
- P-90 “L-Shaped” Dock Seals: Designed for wider door openings, providing a more expansive side seal.
- Inflatable Dock Seals: Inflate with a blower after the truck is docked, providing the tightest seal for maximum environmental control, often ideal for cold storage or sensitive applications.
- Dock Shelters: These systems create a flexible enclosure around the trailer, allowing it to pull under and into the opening. They are highly adaptable to a wider range of truck sizes and offer excellent durability.
- Soft-Sided Shelters (e.g., Ultra Dark, Diverter, Sentinel, Commander, Warrior Series): These shelters feature durable fabric curtains that form a seal around the trailer, often with features like rain dams to prevent water infiltration.
- Rigid Dock Shelters: Feature a rigid frame with durable fabric curtains, providing robust protection and often incorporating translucent panels for natural light.
- Collapsible X-Frame Shelters: Designed to retract when not in use, offering protection without obstructing the doorway.
- Rail Car Shelters (Mechanical & Inflatable): Specialized shelters for sealing off rail cars during loading/unloading, ensuring environmental control for rail-served docks.
- Perma Rain Dam: An innovative accessory designed to prevent water infiltration at the top of the dock opening, working in conjunction with seals or shelters.
- Specialty Products: PermaTech also offers solutions like metal hoods, traffic doors, and other accessories designed for optimal loading dock performance.





The Benefits of Choosing Panel Built Through Dockstar Industrial:
- Superior Environmental Control: Effectively block out dust, debris, insects, and harsh weather conditions (rain, snow, extreme temperatures), maintaining a consistent internal climate. This is crucial for cold storage, food processing, and any facility requiring strict environmental control.
- Significant Energy Savings: By minimizing air infiltration and exfiltration, dock seals and shelters can dramatically reduce heating and cooling costs, leading to substantial energy savings and a quick return on investment.
- Enhanced Safety: Prevent dangerous slip-and-fall hazards by keeping rain and snow out of the loading dock area. They also contribute to overall safety by protecting workers from drafts and uncomfortable temperatures.
- Product Protection: Safeguard your inventory from exposure to the elements, moisture, and contamination during the loading and unloading process.
- Increased Productivity: A comfortable, dry, and clean loading dock environment leads to increased worker morale and efficiency, as personnel can focus on tasks without battling adverse conditions.
- Extended Door Life: By shielding your overhead dock doors from constant exposure to weather, seals and shelters reduce wear and tear, prolonging the lifespan of your doors and lowering maintenance costs.
- Custom-Engineered Solutions: Perma Tech’s focus on customization ensures that the dock seal or shelter perfectly fits your specific dock dimensions, truck fleet variations, and operational demands.
