Greenhouse ,or conservatory create an important role in daily life.It brings green in the cold winter ,,and some big greenhouse ensure that we can have higher output.
The greenhouse thermal insulation is an very important factor that affect the interior temperature.while glass is the deciding thermal conductive.Greenhouse glass types are below:
Traditional Greenhouse glass are 3mm or 4mm tempered glass ,the advantage is cheap and higher light transmittance,high strength to offer impact resistance.But the shortage is high glass U value,which means the solar energy that pass through the glass.Usually 3mm or 4mm tempered glass U value is 5.8W/M2.In summer ,the greenhouse temperature will increase very high if there’s insufficient ventilate facility or measure,while in the winter,the inside temperature will be very low,owners have to use air conditioner to keep the indoor warm.
New insulated glass are used in more and more greenhouse projects.Compared with traditional single glazing glass,it’s price maybe 3-4 times higher,but it has low U value and the indoor temperature can be controlled very well.
Insulated glass is widely used in buildings,especially in high rise buildings to increase he building energy efficient,clear insulated glass U value is only half of single piece glass,about 2.8W/M2.When high performance low e coated is applied,the U value can decrease again to 1.6 or even 1.1W/m2.In Summer,it reflect most solar energy and keep indoor cool and in winter,it prevent the heat going outside.
Despite above 2 mentioned glass,there’s also hard coated low e glass.It’s low e coating on single piece glass,it’s energy efficient is between single piece tempered glass and insulated glass,U value 3.8w/M2 but can have 80% high light transmittance.It’s will a perfect option for most greenhouse owners.
