A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

A door frame 1 has a frame post 3 which is secured with a rear side 5 against a reveal 7 of a wall opening 9 by means of a number of wall clamps 13. Each wall clamp 13 has two clamping parts 15, 17, each consisting of a fastening part 19, 21 and a clamping jaw 23, 25. At the rear 5, the frame post 3 is provided with a groove 27 which extends over the entire length of the frame post 3 and is present at an angle 29 of 10-50 degrees to the rear side. The fastening part 21 of the clamping part 17 partly protrudes into the groove 27 and is displaceable in and out of the groove 27 by turning screws 31 more or less in the door frame 3, which screws protrude through holes 35 present in the clamping jaw 25.

An illumination system is provided for an access door may include an elongated illumination housing configured to be coupled to at least one of an upstanding jamb and a corresponding jamb casing extending along the one side of the access door, an elongated light transmissive cover coupled to the illumination housing, an elongated light pipe received within the illumination housing, an illumination source housing operatively coupled to one end of the light pipe, an illumination source disposed within the illumination source housing and configured to produce and transmit visible light into the light pipe so as to be visible through the light transmissive cover, a source of electrical power, and a control unit configured to selectively apply electrical power from the source of electrical power to the illumination source to produce the visible light.

An attic door support and trimming system includes a plurality of frame sections each having a base wall with an inner edge, an outer edge, a top side and a bottom side, a first end and a second end. A vertical wall extends upwardly from the base wall and is spaced from the inner and outer edges. The first and second ends of different frame sections are positionable against each other to form a rectangular shaped frame. The frame sections each are telescopic to allow a size of the rectangular shaped frame to be adjusted. The top side of the first flange is abuttable against the ceiling adjacent to the opening and the top of the second flange supports a cover when the cover is placed in a closed position closing the opening.
