OUR weeks ago we showed one of the welded muntin joints of Pond Continuous Sash. Every joint of that sash is solidly welded into permanent rigidity.
Here we show a corner joint of Lupton Counterbalanced Sash, before and after grinding. It, too, is welded into a continuous mass of metal. Not the minutest crevice remains to harbor corrosion.
Lupton Counterbalanced Sash is in a class by itself among sliding sash. Massive in design and handsome in appearance, with large lights unbroken by horizontal muntins, it gives a striking dignity to buildings containing it. Air leakage is minimized by closely-fitting jambs and mullions; and this close fit is preserved by the permanent rigidity of the welded assembly. High ventilating efficiency is secured by the counterbalanced principle, since top and bottom openings are always equal.
Lupton Counterbalanced Sash is used both for factories and for offices. Shall we send Catalogue 10-LCB?
