Roof Lanterns in Ascot
Korniche roof lanterns are one of the most frequently specified products on Ascot’s Arts & Crafts and period homes, where architect-designed kitchen extensions demand overhead glazing that floods the space with natural light across the SL5 postcode. The patented snap-fit system and slim 40mm rafter create the cleanest roof lantern on the market, with no tie bars needed up to 3m x 1.5m and bespoke sizes available up to 6m x 4m. Many Ascot projects combine a Korniche roof lantern with Cortizo or Schuco bifold or sliding doors below for maximum light and garden connection. Self-cleaning glass, solar-control coatings and integrated LED downlighters are popular upgrades. We have completed Ascot projects on streets close to Ascot Racecourse and Windsor Great Park. Properties inside the Ascot, Sunninghill and Sunningdale Conservation Area need Royal Borough of Windsor and Maidenhead approval for replacement glazing. We handle that liaison as part of every quote.
