U glass is a glazing system that is fully waterproofed using external grade glazing silicone in the joints between the U glass planks, between/in the perimeter aluminum U channel framing and up to the aperture. The correct grade of silicone will be supplied as part of the U glass system, but for the purpose of specification, a high quality, low modulus silicon is recommended from Dow Corning or similar.
The uniquely designed and manufactured U Glass Technology (thermally broken) perimeter U channel is produced with drainage slots. In the event of vandalism or failure, leading to water being able to penetrate the outer blade or silicone joint; the water would drain from the bottom of the panel to reduce leaking internally.
The channel finish can be anodised or powder coated to any RAL colour.
