Abstract

A method of fitting a window to replace a sash and case window, without removing the existing case comprises removing the sashes of a sash and case window and installing a replacement window in the existing case. The replacement window comprises a first lower hinged sash, and a second upper slidable sash.

Description

SPECIFICATION Window This invention relates to the replacement of sash and case windows.

Replacement of sash and case windows is an expensive procedure due to the amount of labour involved in stripping out the old sashes and casing.

In many cases the existing windows are not satisfactory in respect of draught and sound exclusion and it is difficult to double glaze such windows without radically altering the case.

New fire regulations regarding escape routes also may not adequately be met by such windows. Indeed many replacement windows available on the market at present do not meet the standards required by some departments in this respect.

An object of the present invention is to improve methods of fitting windows and provide an improved window.

According to the present invention there is provided a method of fitting a replacement window which comprises removing the sashes of a sash and case window and installing a replacement window in the existing case.

Further according to the present invention there is provided a window which comprises a rectangular frame having two end members and two side members, a first sash hinged to one side member of the frame so that it can be swung to and from a closed position in which the first sash is bounded by an end member and adjoining side portions of the side members, and a second sash slidable within the frame past the first sash to and from a closed position in which the second sash is bounded by the other end member and remaining portions of the side members.

The invention will now be described in more detail with reference to the accompanying drawings in which two views of an embodiment of the invention are shown.

The embodiment shown is similar in appearance to a sash and case window and thus when used as a replacement window does not detract from the character of a building. It has a top sash 1 hung on "unique" type sash balances 2 fixed to a frame 3 and a bottom sash 4 hinged on the frame 3, which opens to the interior of a room to satisfy fire escape regulations and for cleaning purposes.

A draught excluder 5 such as that available under the trade mark ''Igloo'' is provided.

Installation is a remarkably simple procedure compared with the known methods of replacing sash and case windows. The sashes are removed from the existing window, the sill is cut back and the facings are repaired if necessary. The new window is then simply fitted into the existing case.

Although the above description refers to a replacement window the window can also be used as an original rapid installation window for new buildings.

Thus this invention provides a relatively cheap and easy method of installing windows due to the reduction in time and effort required to prepare the casing for installation.

1. A method of fitting a replacement window which comprises removing the sashes of a sash and case window and installing a replacement window in the existing case.

2. A method according to claim 1 wherein the replacement window comprises a rectangular frame having two end members and two side members, a first sash hinged to one side member of the frame so that it can be swung to and from a closed position in which the first sash is bounded by an end member and adjoining side portions of the side members, and a second sash slidable within the frame past the first sash to and from a closed position in which the second sash is bounded by the other end member and remaining portions of the side members.
