Both in summer and winter, greenhouses will need insulation to keep a steady temperature. Greenhouses are passive sun gatherers and will heat naturally over summer. During winter on the other hand, your greenhouse will need extra insulation and heating (depending on the climate you live in). Without insulation your greenhouse runs the risk of becoming too hot during summer and too cold during winter. Greenhouse insulation is important to lower your heating costs and will give you a quick return on investment. The most commonly used insulation is bubble wrap, that can be used on the inside or outside of your greenhouse (or both).
In times with lots of sunshine the temperature of your greenhouse might become too hot for certain plants. If so, it is advisable to install a shade cloth at the inside of your greenhouse. This will make sure your greenhouse temperature is under control and your plants aren’t burning or drying out. There’s lots of different kinds of greenhouse shade cloths, so make sure you choose the right one for your plants or vegetables.
Combine the use of shade covers with the ventilation of your greenhouse through automatic window openers or ventilators to get your plants safely through summer.

Depending on the temperatures in your region, it’s important to insulate your greenhouse to protect your plants from frost. Glass greenhouses are a bit more sensitive to frost than polycarbonate greenhouses. If your area has long periods of frost, it is advisable to insulate every greenhouse. The easiest and cheapest way to do so, is using simple bubble wrap. We would advise you to get a role (or more, depending on the size of your greenhouse) right before winter, so you’re ready to take action when the weather man (or your smartphone) predicts frost coming up.
Insulate your greenhouse on the outside, inside or both. When you do it on the inside, your bubble wrap is protected from weather conditions and will last you longer. The downside is that it’s a bit more difficult to get in all the corners and get the bubble wrap attached where it needs to be. Make sure you also make a bubble wrap curtain in front of your door. This will prevent the cold from coming in when you open it.
