And, he told Dan and Heather, an important installation requirement is that the frame not berotted or out of square. Scratch that option for Charlestown.That left variations on a theme of complete window replacement—sash, balances and frame (andsometimes exterior trim). With standard window openings (meaning sizes that the manufacturermakes plenty of), it's possible to simply remove your old windows and slip in a new wood unit. If theexisting openings are close to standard size, they can be modified (i.e. made smaller) toaccommodate the new units.The trade-off here, says Harman, is that the "daylight opening"—the glass area — is reduced. Thesame thing happens with most vinyl replacement units, since the vinyl, less stiff than wood, has to bemade thicker. A standard 20"x 28" wood replacement window is in the $150 to $250 range, saysHarman, with vinyl units around $175. Then there's the task of installing them, which, whenretrimming the exterior is included, can cost up to $400.The problem for the Beliveaus was one of the very features that attracted them to the house: itshuge windows. The ones in the living room measure 7'6" x 3'2"—most definitely not a standardsize—and most of the others were similarly atypical. Clearly, this would be a custom order. JayHarman brought us a sample window by a manufacturer that could make just about anything weneeded. Large size? Not a problem. Two-over-two light pattern. Insulated glass with interior spacerbar (goodbye triple-tracks). Cladding, extruded period-profile casing and exterior muntin bar all inaluminum for ultra-low maintenance. Wood interior. High-quality weatherstripping and locks. Tilt-incleaning. Add in a baked-on exterior paint in a period-perfect black-green, and we couldn't resist. Ofcourse, all these features came with a price tag. The living room windows retailed for about $700; a20"x 28" window with similar features would have been $320.After carefully measuring our openings, brick-to-brick, we ordered. Six weeks later, our windowsarrived. When it came time to install them, we got lucky: the weight pockets from the building'soriginal windows were still there, hiding behind the aluminum balances of the replacements. Theconsiderable extra space they provided between the brick opening and the sash allowed Tom and hiscrew to build a rough 2x4 frame to accept the new windows, which they slipped in from outside,leaving the buildings beautiful (and hard-to-replace) interior casing untouched.[1.6]1.7 – FICHES TECHNIQUES, FENÊTRES & EXEMPLES DE RÉALISATIONS (SUISSE)Lors d’intervention sur des façades de bâtiments ayant une valeur patrimoniale, les fenêtresanciennes, leur entretien et leur adaptation aux exigences phoniques et thermiques exigent uneattention particulière. En effet, elles participent autant au décor intérieur qu’au dessin architecturalde la façade. En premier lieu, la conservation de la fenêtre existante doit être envisagée. Cetteconservation nécessite d’examiner l’intervention la plus adaptée au type et à l’état des fenêtresanciennes. Les interventions sont de quatre ordres : entretien et réparation, restauration avecremplacement du verre, restauration avec ajout d’un écran, qui prendra la forme d’un panneaupartiel, d’un survitrage ou d’une double fenêtre, et transformation-restauration. Un remplacementdes fenêtres ne sera considéré qu’en dernier lieu, si leur état est à ce point dégradé qu’unerestauration n’est plus possible. On commencera alors par poser l’hypothèse de ne remplacer que laou les fenêtres endommagées, et ceci dans le respect des dimensions, des partitions et desmatériaux existants. Les aspects phonique et thermique doivent dans chaque cas être traités, mêmeJuin 2012Les Bâtisseurs d’Emmaüs36
