JOHN TORENSTRA JR. specialises particularly in the glazing of wide span and lattice greenhouses.  
By using qualified personnel and advanced equipment such as glazing platforms, we are able to translate your needs into high-quality products in an efficient way.

All of our machinery has been tested by the Labour Inspectorate, complies with current safety requirements and is operated by qualified personnel.

It’s generally thought that work in greenhouse glazing is physically heavy and not without danger.   
However, this is an outdated view.

These days, we use a comprehensive programme of machines and equipment which lighten the work considerably and makes it safer.

We demand nowadays more mental strength from our employees than physical.

For example, operating the tractors and cherry pickers must be done according to policy to ensure a good result.

The various projects are completed quickly and tidily by a young, motivated team. Both experienced and inexperienced employees find a place in our glazing team once found suitable.
