Skylight types

Skylights are available in glass, acrylic and polycarbonate. A glass skylight is weaker and more expensive than a polycarbonate or acrylic skylight. Polycarbonate is a very strong material, but is more expensive than acrylic. A cheaper option is acrylic, also known as plexiglas. It is stronger than glass but not as strong as polycarbonate. You can also choose:


  • The shape: round, square, rectangular, flat, shallow pitched or even pyramid shaped
  • The opening mechanism: electric or manual
  • The insulation: skylights and roof hatches are available with various insulation values
