A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

A profile assembly includes two profile elements, a profile connecter element, and at least one fastening element connecting the two profile elements to each other using the profile connecter element. The first profile element includes guide channels for receiving two leg parts of the profile connecter element. The first profile element includes at least one fastening channel for receiving the fastening. The second profile element includes a U-shaped recess for receiving the profile connecter element. In the base, the profile connecter element and second profile element in the bottom of the U-shaped recess thereof respectively include at least one mounting opening corresponding to the fastening channel for passing the fastening element there-through. At least the second profile element is formed in several parts and includes two shell parts in the direction of interior and exterior rooms. The profile shell parts are connected to each other, yet thermally insulated.

An element, having an insulating glass unit mounted in a metal frame assembly, may include an outer frame assembly comprising a unitary outer frame member, a plurality of mounting studs projecting from said outer frame member in perpendicular relationship in a first pattern aligned with a first complementary pattern of mounting bores defined in an insulation body assembly when the outer frame member is disposed in common alignment with the insulation body assembly, an inner frame assembly including a multi-part inner frame member having a set of discrete inner frame side members, a plurality of mounting studs projecting from the inner frame member in a second pattern aligned with a second complementary pattern of mounting bores in a rear surface of the insulation body assembly, each mounting bore having a respective mounting bore sidewall spaced from an aligned mounting stud received therein, and a curing connection medium in the plurality of mounting bores to define a plurality of mounting connections from the inner and outer frame assemblies to the insulating body assembly.

A fenestration formed of flattened steel with special thermal break structures therein.

A fire shelter including: a foundation including a slab; an internal frame mounted on the slab; external cladding formed from heat resistant masonry panels supported by the internal frame, the external cladding including wall cladding including wall panels and defining a door opening and roof cladding including roof panels; and a door mounted in the door opening, the door including a door frame hingedly connected to the internal frame adjacent to the door opening and door cladding including door panels formed from heat resistant masonry panels supported by the door frame, wherein when the door is in a closed position, the door cladding closes the door opening.
