Thermal insulation makings of skylights SUNIZER™

Excellent thermal insulation properties of the skylight reduce heat loss from the building and provide a guarantee of a pleasant environment. Thanks to these features the skylight reduces heat loss and heat gain.

Into the skylight cannot get any water vapor. When coming into the skylight and the subsequent contact with the cold dome could cause condensation. The greatest emphasis to install skylightis put on tightness of the ceiling diffuser. When installing each part of the skylight then must be correctly taped all the joints by vapor tape which is included. After taping of all connections is recommended to insulate the skylight tube by thermal insulation.

To ensure normal thermal insulation parameters of the house is suitable for SUNIZER™ skylight installation with thermal-insulating double glass inserted into the ceiling diffuser.

Thermal-insulating element THERMIZER™ is primarily designed to be installed with skylight SUNIZER™ into passive houses or to houses with increased demands on thermal transmittance.
