Tier on Tier Shutters are probably the most flexible style of all shutters. Similar to full height shutters, tier on tier shutters cover the full window, but each panel is split into two separate operating panels. So but having top and bottom ie two separate tiers, it gives you the option to fold back each panel on each tier independently. This allows the top half to be folded right out of the way, so that you can maximise the daylight ingress, whilst still retaining privacy from the lower panels. The tiers can be separated by a horizontal T-bar attached to the shutter frame, which improves strength and provides support to the top tier. The bar also reduces unwanted light sipping through the break between the tiers.
