DE2448507A1 - House insulating folding shutters - with heat or sound insulating materials inside filling hollow between pane and shutters - Google Patents

Abstract

The purpose is to improve the insulation of houses, including old houses, where the windows are the weakest point in any heat-insulating system, and where the shutters normally serve primarily to exclude the sun or to prevent intrusion. The folding shutters have heat and/or sound insulating materials fitted on the inside in such a way that they largely fill the hollow space between the window panes and shutters when the latter are in the closed position. This saves fuel, is cheaply and easily fitted, makes the area near the window more comfortable to sit in and reduces air currents in this area, so that the heating can be switched off earlier, and improves sound insulation.

Description

Description and claims 1.) Title: Isolier-Elappladen 2.) Field of application: The invention relates to folding shutters, as z. @.

are often used in residential buildings, especially old buildings.

3.) Purpose: For the thermal insulation of buildings is the window mostly the weakest point. In normal residential buildings, this is on the order of magnitude Half of the heat is lost through the window. The result described below allows the amount of heat passing through the window to be averaged over 24 hours, cut in half. That would make a quarter of the heating costs in the order of magnitude save.

4.) State of the art: Folding shutters are primarily used for the time being the darkening of the room and the protection against break-ins.

5.) Criticism: The one between the inside of the closed shutters and the outside of the window is usually 10 to 15 cm deep not used for isolation purposes.

6.) Task: The invention aims at the space between the outside of the window and the inside of the closed shutters for purposes of warmth (and also Use sound) insulation 7.) Solution: The process is based on the inside of folding shutters to apply thermal insulation materials in such a way that they can be used when the shutters are closed Fill in the cavity between the window pane and the folding window (Fig. 1).

8.) Further configuration: a) The folding shutter can, if necessary, sealed against the outer wall by a non-running seal (item 6 in @ild la) will.

b) To protect against moisture, the insulation material is e.g. put in a plastic bag (e.g. polyethylene).

(Pos. 4 in Fig. La).

c) To beautify the outer picture @is before drc isolation aterial a facing made of wood or synthetic material is attached (item 5 in Fig. la).

9.) Achievable advantages: (1) Considerable savings in heating costs.

(2) Low cost, practically no harm to residents on Mondays.

(3) Comfort of the window area in the evening, as the temperature of the Window pane reads high.

(4) The surface temperatures of the window and wall are also approximately the same when the heating is switched off, therefore no excessive air movement, and earlier switch-off heating possible in the evening.

(5) Publicity of the sound catastrophe.

10.) Description of an exemplary embodiment: See Figure 1 and section 8th.
