常见问题

Q What is a sponge dock shelter?

A:Foam dock shelters, or sponge dock shelters, utilize side pads which are foam-filled along with a head curtain or pad to seal off the opening of a loading dock to the back of a truck. This prevents the dock area from being exposed to elements, along with pest and temperature changes, while loading and unloading.

Q:How does a sponge dock shelter differ from a dock seal?

A:While both utilize foam, sponge dock shelters enable the truck to park within the perimeter of the shelter, allowing for full, unobstructed access to the trailer opening. A dock seal, on the other hand, requires the truck to “nose” up to the pads which slightly restrict access to the trailer’s interior.

Q:What's the difference between a sponge shelter and an inflatable shelter?

A:Dock sponge shelters use high density foam for passive and durable sealing protection, and deflated cubical shelters use a blower which requires power and has more moving parts.

A:Yes. They are designed to service a wide range of truck widths and heights. The flexible side and head components are capable of compressing and adapting to various trailer dimensions which makes them highly versatile.

A:Standard shelters are usually designed for dock openings of 8 ft x 10 ft or 9 ft x 10 ft in size. Due to their customizable nature, standard shelters can be modified to match customizable rough opening widths, with extensions usually varying between 18 and 30 inches.

A:The pads are made with closed cell, high-density, polyurethane foam and are wrapped in a weather resistant PVC, polyester or vinyl protective coating. The sponge dock shelter frame is usually made from treated wood or galvanized steel.

Q: How well do sponge shelters resist wind and rain?

Q: What is the expected lifespan of a sponge dock shelter?

A:If used and serviced regularly, a sponge dock shelter is designed to last for 5 to 10 years plus. The lifespan of the sponge dock shelter however is determined by the number of trucks passing through as well as the weather.
