Insulationg Concrete Floor Greenhouse

That is why pea gravel is a good option.

Insulationg concrete floor greenhouse.

If you poured a concrete slab for your greenhouse foundation you have a perfect floor as a bonus. Build a frame against the back wall of the structure to stack those 55 gallon drums three high and keep the front row low so the most surface area is hit by the sun. At ceres we go one step further and actively heat the soil using a ground to air heat transfer gaht system. It absorbs heat from the sun and releases it into the surrounding environment during the day and night.

The sill acts as a insulated buffer between the concrete and the greenhouse frame reducing heat loss. Concrete will also reflect light and retain heat throughout the day. Install a drain in the center of the floor that leads to a gravel pile underneath the greenhouse or to a pipe to carry. Most of the footprint will be used as a planting area which may or may not need a level finished surface.

Leave a 1 inch trench 12 inches deep around the external edge of the foundation. Apart from providing good drainage the best greenhouse floor should insulate the structure when it is cold outside. The best material for a solar greenhouse heat sink floor is some kind of stone or concrete. This uses an airflow system to actively draw hot air from the greenhouse underground so the greenhouse can store more heat in the soil.

The thicker the better of course. A concrete floor is easy to clean and walk on and if poured correctly should drain away any excess water. What to use for greenhouse floors. A concrete slab may be the easiest type of greenhouse footing to keep clean.

Insert the greenhouse insulation and the exterior sheets. Insulation quilts over the greenhouse at night keeps more heat from being lost. You want heat exchange to occur between the greenhouse environment and the thermal mass of the soil. Install the perimeter and area piers and the solid plastic foundation beams.

The thermal mass of the stone will absorb and then release the solar energy stored during the day. You will add spray foam insulation either polystyrene or polyurethane under the greenhouse floor in the next step. If poured properly it has sufficient slope to drain away the excess water. There are several options for greenhouse flooring materials.

This insulates the floor and helps keep it warmer in the winter. The most ideal is a poured concrete floor especially if it s insulated. One recommended option whether you use a slab or wall is to fasten a 2 x 4 sill on the top of the foundation. Even an insulated year round greenhouse doesn t need a finished floor as a house does.
