Greenhouse Insulation – All About Greenhouse Insulation

Greenhouse Insulation | What is That?

Greenhouse Insulation. Adding a layer of insulation to your greenhouse will help you save on energy and money. Insulation will benefit greenhouses that are located in colder regions where more heat is generated to keep the greenhouse at a certain temperature. Again, the insulation you install will depend on your location, your plants and your greenhouse. When researching the type of insulation you will need to install, consider these options:Double Glazing Insulation

GREENHOUSE INSULATION – Double Glazing Insulation

The concept of arranging several glass panes into an individual unit is known as double glazing.  Double Glazing are double glass panes divided by a space of air to help reduce heat exchange across a section of the greenhouse envelope.  Glass is used to allow light to enter the greenhouse from the outside as well as provide view from the inside.  The primary advantages of creating multiple glass panes into a single unit are the significant levels of thermal and acoustic insulation attained due to the existence of either a gas, like air, or total vacuum in the area the in between the glass panes.  The insulation and security characteristics of the glass are improved, without reducing the portion of light that is permitted inside the buildings.  This is why this insulation method has become very popular recent times.

Using glass panels in greenhouses allows access to light.

Bubble Plastic Insulation

Flexible plastic or Bubble plastic is made of multiple skins of clear plastic with air pockets between each skin. Bubble plastic should survive for three or four seasons; making it a very efficient method of insulating your greenhouse. An individual layer of plastic sheeting will allow for more light penetration but will not insulate as well as bubble plastic.  Plastic sheets can be used during the colder months as a type of double glazing by connecting them with clips that attach with the greenhouse frame.

In the coldest climates the plastic sheet is used for a double glazing.

Thermal Screens Insulation

Thermal screening strategies (shade, heat retention, or blackout curtains) lower heat loss by decreasing the amount of air required to be heated.  A type of attic is created in the greenhouse that establishes an insulated air buffer, and reduces the stratification of heat to the roof.  Throughout the summer screens can be integrated over your plants, bringing temperatures right back to an ideal growing range.  These cable influenced systems are managed by electric drive units with reversing handling and built-in limit switches. They can be run manually or by computer.

Shade Net
In warm climates, the shade mesh is used for retaining heat on the roof.

Base Cladding Insulation

Base Cladding on the bottom of glass ground greenhouses helps decrease the amount of heat loss tremendously. During winter add polystyrene panels along the foot of the glass panes to offer added insulation. Detach them before the summer boundary crops are planted.
