The structural lintel system is supplied complete with thermatic islulation giving a respectable “U” value qualification. The Cavity closer legs are supplied with thermal break as standard and integrate with the base closer to give a sturdy frame for building intergartion. Tharmal values can be firther enhanced by choosing the specially designed S42 Insulated steel shutter curtain option, combining supreme security with added insulation.
