Welcome to our world of high-performance, triple-glazed frameless units, expertly designed for both flat and pitched roofs. Whether you prefer a portrait or landscape orientation, our units offer unparalleled versatility to suit your architectural needs. Each unit is a marvel of engineering, consisting of three distinct layers: a robust 6-millimeter thermally toughened top glass layer, a sturdy 4-millimeter middle layer, and a highly efficient 8.8 low E laminated bottom layer. What sets our units apart is the innovative 15-millimeter warm Edge spacer nestled between each pane. This spacer is filled with Argon gas, significantly reducing heat transfer and maintaining a comfortable ambient temperature indoors, regardless of the season. Our frameless units boast an impressive U-value of 0.9, testifying to their exceptional insulating capabilities-the lower the U-value, the better the insulation. Regarding the silicones, we suggest the following products. Black weather silicone – DOWSIL 791 Weatherproofing Sealant. DO NOT USE ACRYLIC SEALANTS! Ensure you’re using the right silicones to install and weather tight your Skylight. We recommend the above products as fully compatible with our glazing unit silicones. Using the wrong silicone can lead to discoloration, adhesion loss, and potential leaks due to a chemical incompatibility. It may also lead to depressurization of the glazing unit (allowing moisture to penetrate inside the glazing unit and cause internal condensation), weak bonding to the support structure, and poor weather tightness.
