Hi. Having just bought and used "silver screens" from the company silver screens forr the first time, this was the best purchase i have made on a single item for my van. Cannot fault them. aprox 60 seconds to install and less to take down, no one can pinch them as long as your cab doors are locked, no condensation at all, and the heat retention..... Well from dorset in sept to scotland at xmas in -12 absolutely fantastic. The service and delivery is also 1st class. I rang on day one to enquire, brochure arrived day two, i ordered on day two and they arrived day four. 12 month garunteed and an option to part exchange if i change my van.
