How Our Thermal Barriers Work With Doors

So what is a Thermal Barrier?

A thermal barrier is simply a product that stops or slows one or more of the three types of heat transfer. Those three types of heat transfer being conduction, convection and radiation. 

How is heat transfered?

Heat travels from a warm area to a cool area by a combination of conduction, convection, and radiation. Heat flows by conduction from a hotter location within a material to a colder location. Heat transfer by convection occurs when a liquid or gas is heated by a surface, becomes less dense, and rises (natural convection), or when a moving stream of air absorbs heat from a warmer surface (forced convection). Radiant heat travels in a straight line away from any surface and heats anything solid that absorbs the incident energy. Radiant heat transfer occurs because warmer surfaces emit more radiation than cooler surfaces.

For example, when the sun heats a metal roll-up door, it's primarily the sun's radiant energy that makes the roll-up door hot. A large portion of this heat travels by conduction through the metal doors materials to the inside of a building. The hot roll-up door material then radiates its gained heat energy onto the cooler part of the building.

What are the Temperature Retention products?

The Weather Barrier and Temperature Retention family of products (Patented & Patent-Pending) are developed to retain heat and cooling in building envelopes as well as eliminate air-flow and airborne debris entry. Our products can be used for a variety of applications in all Commercial and Industrial building applications.

Our Patented Weather Barrier products are highly desired since we can effectively manage all types of heat transfer for all types of metal door applications, including roll-up and sliding metal doors. Our products are made in the USA with varieties of layering materials, each with their own unique purpose and climate situation.

Case study of Weatherized Door Curtains™ used in a Self-Storage Application

Without a Weather Barrier Door Curtain™ installed directly behind a roll-up door, every item inside a heated self-storage unit, including the walls and ceiling, are emitting radiant heat. That heat, is absorbed by the roll-up door, because it is cooler than other surfaces in the unit. The heat is then transferred outside via conduction and lost. The opposite is true for your cooled or non-cooled self-storage units on a hot day. The roll-up door is the warmest area of the unit, and so heat is radiated from the door and absorbed by the walls, ceiling, and any object inside the self-storage unit.

By installing a Weather Barrier Door Curtain™ System, you are effectively stopping the heat transfer. Radiant heat does not become conductive heat until it is absorbed by an object. The Weather Barrier Door Curtain™ System reflects the heat back before it can be absorbed by the roll-up door, thus preventing the radiant heat from becoming conductive heat, wasting energy costs and stopping air-infiltration.

Whether your Aerospace needs are to stop solar heat entry, air-conditioning loss, eliminate airborne debris entry or ensure that your sterile satellite manufacturing lab isn’t disturbed from outside influences, our Weatherized Door Curtain Systems are a definite solution. We have Door Curtain sizing capabilities up to 40’ in width & 90’ in height, with either manual or full automation.

From testing facilities, labs, military parts and aircraft manufacturing facilities, our Weatherized and Windproof Door Curtains ensure that everything from air-borne debris entry to solar heat deflection will not delay that “key” project from being completed due to outside element entry or weather interruptions. Our large scale Door Curtain manufacturing capabilities extend to 200’ in width & 120’ in height with full automation.

Fulfilling the needs of the GSA and the thousands of buildings they manage with our Weatherized Door Curtains, we can effectively eliminate air and/or debris infiltration while also eliminating heat and/or air-conditioning loss. We have Door Curtain manufacturing capabilities to 25’ in width & 30’ in height, with either manual or full automation.

From small warehouses to large manufacturing plants, our Weatherized Door Curtains facilitate the need to effectively eliminate air and/or debris infiltration while also eliminating heat and/or air-conditioning loss. We have Door Curtain manufacturing capabilities to 25’ in width & 30’ in height, with either manual or full automation.

We developed a wall-to-wall and floor-to-ceiling Weatherization System exclusively for the specific needs of the typical metal roll-up door used within the Self-Storage industry. Revolutionizing the ability to now completely weatherize self-storage buildings while having full walls of metal doors on outside facing storage units.
