VENTILATION METHODS

(To the Editor.) Sir,— Your correspondent, "M.W.Av" discussing the Health Department's article on ventilation, refers to the difficulty of opening windows in ttormy weather, permitting the entrance of driving rain. In the case of'gash windows, this is easily prevented by the use of a Hinckes-Bird board, which is made in the following way: A lin board, 6 or Bin wide, ia cut 10 that its length is about half an inch less than the width of the sash. The bottom sash is then raised, the board placed along the (till, and the sash dosed down on to it. If a more workmanlike job ie desired the board is cut so that its length exactly equals the width of the sash. The edges are bevelled to fit closely to the sill and to the under edge of the sash. It is then sawn through the.middle and hinged with a strip of leather. Finally, .it can be painted to match the surrounding woodwork. With the board in position and a wind blowing ample fresh air is admitted between the upper and lower sashes, and being directed upwards, mixes well with the air in the room without 'causing draughts. If the wind drops, of course, the board should be removed, and the window opened iv the ordinary way. I have made and used one of these boards, and can vouch for its efficacy.—l am, etc., •.. ■■' '■ . F.S.M. Particulars of anotlipr cheap 'method .are supplied by "C.8.X.." as follows:—Take ii plieet of flali galvanised iron about four inches wider than the top board (outside) &l ibq Ki&doiK fj3sJ§ ?^i I2SS enough, £O|

allow about Bali: an inch to be bent at right angles over each end of the top board. Place the sheet over the top board of the window frame, inserting it under the flashing which comes over the top edge of the top board. Fasten with galvanised tacks. When this is in place the top sash can. be pulled down about three inches in any weather without the rain coming in, and the spaces between the iron Rnd the top sash and_ between the two' Bashes give ample ventilation when it would otherwise be too stormy to open the sashes.
