How Does Heat Insulation Work?

Most people know that heat insulators are used a lot when it comes to construction, but how does heat insulation work? Well, heat insulators are generally placed between two dividers or planks in order to increase their insulation properties. This is one of their main uses, however heat insulation is also used in fridges, air conditioners, industrial machinery and in many, many more areas.

what is a heat insulator

Pretty much any material places between two plants will work as an insulator, although some materials are much more efficient than others.

Insulating materials:

  • Aluminum
  • Cotton
  • Clay
  • Hemp
  • Wood fiber
  • Rockwool
  • Polyurethane foam

How does heat insulation work? | Types of Heat Insulators

There are plenty of different types of thermal insulators on the market that can easily insulate heat. There are various kinds of heat transfer, such as conduction, convection and radiation, and each of these types requires a specific type of insulator.

Heat insulation | Conduction

The most used type of heat insulation is that which stops heat transfer via conduction, which is essentially when heat is transferred via direct contact. This is the same type of insulation that you can find in houses and used in various different electrical systems in order to stop heat transferring via contact.

Heat Insulation | Convection

Heat transfer via convection is something that those that use vaporizers know well. It’s essentially the transferring of heat via air flow, gas flow or even liquids. Heat insulators used for convection transfer are designed to stop that warm air/gas/liquid from coming into contact with a specific surface. The materials used are usually sprays, foams and different types of plastic.

Heat Insulation | Radiation

This is the type of heat transfer that indoor cannabis growers are most interested in, as devices in grow rooms such as ballasts, bulbs and other electrical objects radiate heat in the form of infrared rays. Heat insulators used for radiation usually reflect or repel the heat to a certain area, away from wherever you don’t want to heat up. The types of materials used are generally metallic, and it’s also used when building houses, in between walls.
 
Note:
For heat insulators to work successfully or at least be functional, you will need to cover your entire growing area, making sure that there are no holes through which radiated heat can escape. There are a lot of electrical devices involved in growing cannabis and the room/tent can produce a lot of heat – cover absolute everything including the walls, windows, doors and ceiling.

How does heat insulation work? | Cannabis Detection

One of the main ways that the authorities have of finding indoor growing operations is by following the heat signature produced by all of the devices. Both the police and people looking to steal plants use heat detection systems such as thermal cameras, also known as infrared cameras.

These types of cameras read the length of the waves being let off by objects in the vicinity, structures and living beings. Essentially, they detect waves that the human eye can’t see, showing deeper red colors in the warmest areas and blue colors in the cooler areas. People can’t see these waves with the naked eye.

How to Camouflage your Grow Room

If you want to pull out all of the stops and camouflage your grow room from infrared detectors, you’ll need to make sure that the radiation produced by your bulbs and other electric devices such as ballasts and extractors doesn’t reach the walls and floors of your growing room. This is usually done by using various types of metal alloys such as lead and aluminum, among other materials.

The general idea is to cover the inside of your entire growing area – walls, windows, doors, the ceiling – with a specific type of film designed for this purpose. This type of film is called insulation film and it’s usually made out of the materials we mentioned before. They also usually have an external or internal layer of air bubbles, which can help to keep the inside of the room protected against heat changes outside up to 15°C.

Neptune Hydroponics Heat Insulation Film

Neptune Hydroponics designed their very own insulation film for your grow rooms – it’s a great alternative for growing looking to insulate their grow room efficiently and affordably.

This film is also highly reflective and contains plenty of air bubbles, helping to keep the perfect temperature difference indoors – up to 10-12°C difference from the outside temperature.

Dis Swat Heat Insulator

This particular type of heat insulator took the cannabis world by surprise when it first came out – it became a way for thousands of growers to protect themselves from the dreaded infrared cams.

These insulators are essentially composed of two external reflective sheets and an interior air bubble chamber that’s one centimeter thick. This helps to maintain a temperature difference between inside the room and outside of up to 15°C. They also have particular models that have just one reflective side, which is perfect for insulating your home.

Dis Swat AUTOFIX Heat Insulation

The Dis Swat AUTOFIX reflective and insulating film comes with adhesive film on one side so that you can stick it to the wall or any other surface easily, simply and without needing to use duct tape or a stapler.
 
Note:
For the best possible results regardless of the film you’ve chosen, we recommend using Dis Swat AUTOFIX Unions – these items seal al of the joints and connections in the film which can happen when parts overlap or in corners and where the wall meets the ceiling.
