Solar Passive Thermal Blanket Greenhouse

solar passive greenhouse is a Thermal Blanket greenhouse
solar passive greenhouse is Mainly used for For some region if winter temperature is below 0ºC but above -10ºC, quilt can be applied and covered on top of the film to help heat preservation. And if winter temperature is below 0ºC but above -5ºC, double layer film and greenhouse blanket can be used for heat preservation.

Energy Savings
Reduces reliance on fossil fuel or electric heaters by up to 50–70% in cold climates, lowering operational costs.
this Thermal Blanket greenhouse is covered by a greenhouse blanket, Ideal for regions with high heating costs or strict sustainability goals.

Cost-Effective Insulation

Lower upfront cost compared to permanent insulation upgrades (e.g., double-layer polycarbonate panels) while offering similar thermal performance.

Solar passive greenhouse with Brick wall

The Chinese solar passive greenhouse has three walls of brick or clay. Only the southern side of the solar passive greenhouseis covered by plastic film or Polycarbonate sheet. During the day the passive greenhouse captures heat from the sun in the thermal mass of the walls, which is released at night.
At sunset, an insulating sheet -- waterproof warm quilt -- is rolled out over the plastic, increasing the isolating capacity of the passive greenhouse structure. The walls of passive greenhouse also block the cold, northern winds, which would otherwise speed up the heat loss of the passive greenhouse.

Solar passive greenhouse without Brick wall

The greenhouse is made of steel pipes all around (no walls are required), the surface is covered with a film, and the side ventilation system is equipped with a insect-proof net. In order to achieve the thermal insulation effect, the four sides can be covered with waterproof thermal insulation quilt, or do a layer of thermal insulation board inside.Design principle: It is convenient for customers to build greenhouses without walls.

Double layer Solar passive greenhouse

The greenhosue has double arch structure, the outer layer is covered with film, and the inner layer is covered with film and thermal insulation greenhouse blanket. It is Thermal Blanket greenhouse. When the quilt is rolled up, the indoor light increases, the side ventilation promotes the internal air circulation of the greenhouse, and the insect protection net prevents the entry of pests. When it is cold, put down the quilt to create a double-layer insulation effect. Design principle: To prevent excessive rain and snow, resulting in quilt can not roll up the situation. The outer layer can be fitted with a snow shaker to shake off accumulated snow.

Project of Solar Passive greenhouse

Insulation: High - quality insulation greenhouse blanket is essential for minimizing heat loss. The walls, roof, and greenhouse blanket are often insulated with materials such as fiberglass, foam board, or reflective insulation. Good insulation greenhouse blanket helps to retain the heat stored by the thermal mass, keeping the interior warm at night and reducing the need for additional heating sources.
