\u201eFereastra este elementul arhitectural utilizat \u00een construc\u021bii, av\u00e2nd o deschiz\u0103tur\u0103 de form\u0103 regulat\u0103, care este l\u0103sat\u0103 \u00een peretele unei cl\u0103diri pentru a permite s\u0103 intre aerul \u0219i lumina.\u201d Acesta este r\u0103spunsul dat de domnul Google la \u00eentrebarea \u201eCe este o fereastr\u0103?\u201d.<\/p>\n

\n<\/p>

\u00cen secolul 21, indiferent dac\u0103 se deschid sau nu, cu geam dublu sau triplu, din lemn sau aluminiu, ferestrele sunt cu siguran\u021b\u0103 ceva f\u0103r\u0103 de care nu mai putem concepe un trai comod. Acestea ofer\u0103 caselor noastre aspect atr\u0103g\u0103tor, permit luminii naturale s\u0103 inunde interioarele dar au \u0219i capacitatea de a izola termic \u0219i fonic. Pentru c\u0103 ferestrele joac\u0103 un rol at\u00e2t de important \u00een via\u021ba noastr\u0103 de zi cu zi, ne-am g\u00e2ndit c\u0103 ar fi interesant de aflat mai multe despre istoria, originea \u0219i evolu\u021bia lor. A\u0219adar, iat\u0103 c\u00e2teva lucruri pe care (credem c\u0103) nu le \u0219tia\u021bi despre ferestre.<\/p>\n

    Fereastra = fenestra = vindauga<\/strong><\/h4>\n<\/li>\n<\/ol>\n

    Cuv\u00e2ntul latin pentru fereastr\u0103 este fenestra. Traducerea este \u201egaur\u0103 \u00een perete\u201d, \u201edeschidere pentru lumin\u0103\u201d sau \u2026. \u201eoportunitate\u201d. Aceasta din urm\u0103 chiar are sens dac\u0103 ne g\u00e2ndim c\u00e2t de adev\u0103rat\u0103 este zicala: \u201eDac\u0103 o u\u0219\u0103 se \u00eenchide \u00een fa\u021ba ta, ie\u0219i pe fereastr\u0103!\u201d  Cuv\u00e2ntul \u201ewindow\u201d provine de la cuv\u00e2ntul norvegian vechi \u201evindauga\u201d, care se traduce prin \u201eochiul v\u00e2ntului\u201d. Acest termen se refer\u0103 la deschiderile mici, din pere\u021bii caselor vikingilor. Acele deschideri erau concepute pentru a permite luminii \u0219i aerului proasp\u0103t s\u0103 p\u0103trund\u0103 \u00een interior. Dac\u0103 am amintit de limba latin\u0103, merit\u0103 s\u0103 men\u021bion\u0103m \u0219i faptul c\u0103 luna ianuarie a fost numit\u0103 dup\u0103 Janus, zeul u\u0219ilor. Acestea simbolizeaz\u0103 \u00eenceputul \u0219i deschiderea tuturor lucrurilor. Romanii \u0219i-au construit case cu u\u0219i \u0219i ferestre care se deschideau spre interior. Asta pentru a-l onora \u0219i primi pe Janus \u00eempreun\u0103 cu to\u021bi oaspe\u021bii.<\/p>\n

      Fereastra a ap\u0103rut odat\u0103 cu casa<\/strong><\/h4>\n<\/li>\n<\/ol>\n

      Fereastra a ap\u0103rut ca o necesitate practic\u0103 odat\u0103 ce oamenii au \u00eenceput s\u0103-\u0219i construiasc\u0103 locuin\u021be permanente. Primele locuin\u021be, precum colibele din piatr\u0103 sau lut, aveau deschideri rudimentare pentru ventila\u021bie \u0219i lumin\u0103. Fiecare etap\u0103, fiecare progres \u00een construc\u021bia locuin\u021belor a adus inova\u021bii \u00een designul \u0219i func\u021bionalitatea ferestrelor. Dimensiunile ferestrelor, formele acestora, mai mult sau mai pu\u021bin artistice, precum \u0219i num\u0103rul lor erau adaptate la stilul \u00eentregii cl\u0103diri. <\/p>\n

      Astfel, geamurile caselor din Egiptul antic, montate la \u00een\u0103l\u0163ime, aveau doar rolul de aerisire.<\/span><\/p>\n

      Palatele din Creta aveau geamuri largi, pentru a putea admira priveli\u0219tea.<\/p>\n

      \u00cen perioada elen\u0103 au \u00eenceput s\u0103 apar\u0103 mai multe geamuri pe o fa\u021bad\u0103, majoritatea fiind cu vedere spre cur\u021bile interioare. Scopul lor era socializarea \u0219i cultivarea rela\u021biilor interumane.<\/p>\n

      \u00cen stilul gotic \u0219i \u00een arhitectura maur\u0103, dimensiunile geamurilor erau ceva mai mari, iar forma geamurilor se baza pe arcul fr\u00e2nt.<\/p>\n

      \u00cen perioada baroc\u0103 reg\u0103sim deseori geamuri cu ancadramente bogat ornamentate, \u00een timp ce stilul clasicist reduce aceste ornamente la minim.<\/p>\n

      P\u00e2n\u0103 pe la sf\u00e2r\u0219itul secolului al XVII-lea, ca \u0219i propor\u021bie, ferestrele erau mai mult late dec\u00e2t \u00eenalte. Asta  datorit\u0103 faptului c\u0103 \u00eenc\u0103perile aveau tavane foarte joase. Aceast\u0103 propor\u021bie s-a schimbat odat\u0103 cu apari\u021bia tavanelor \u00eenalte.<\/p>\n

      \u00cen arhitectura secolului al XX-lea, \u00eencet-\u00eencet \u00eencep s\u0103 apar\u0103 o serie de cl\u0103diri \u201edin sticl\u0103\u201d. Acestea sunt de fapt o fereastr\u0103 unic\u0103, fiind realizate \u00een \u00eentregime din sticl\u0103 (pere\u021bi cortin\u0103).<\/p>\n

        Egiptenii romani au fost primii oameni care au folosit sticl\u0103 pentru ferestre<\/strong><\/h4>\n<\/li>\n<\/ol>\n

        Cele mai vechi ferestre cunoscute dateaz\u0103 din Egiptul antic \u00een jurul anului 1300 \u00ee.Hr. Aceste ferestre erau de fapt deschideri f\u0103r\u0103 geam, f\u0103cute \u00een acoperi\u0219, pentru a permite trecerea luminii \u00een timpul zilei. Cu timpul ferestrele au \u00eenceput s\u0103 fie \u201eacoperite\u201d. \u00cen \u00eentreaga lume \u0219i de-a lungul veacurilor, diferite civiliza\u021bii au folosit diferite materiale pentru \u201eumplerea\u201d ferestrelor. Astfel s-au folosit corn translucid de animale, cear\u0103 de albine, h\u00e2rtie, p\u00e2nz\u0103, piele de animale sau felii sub\u021biri de marmur\u0103. Se crede c\u0103 egiptenii romani au folosit pentru prima dat\u0103 sticla la acoperirea ferestrelor \u00een jurul anului 100 d.Hr. Aceast\u0103 sticl\u0103 avea o transparen\u021b\u0103 foarte slab\u0103 \u0219i performan\u021be optice reduse. A fost nevoie s\u0103 mai treac\u0103 un mileniu p\u00e2n\u0103 ce sticla a devenit suficient de transparent\u0103 \u00eenc\u00e2t s\u0103 se poat\u0103 vedea clar prin ea. Ferestrele cu sticl\u0103 au devenit comune \u00een case abia la \u00eenceputul secolului al XVII-lea.<\/p>\n

        Odat\u0103 cu st\u0103p\u00e2nirea me\u0219te\u0219ugului sticlei, folosirea acesteia pentru ferestre a devenit rapid un fapt obi\u0219nuit \u00een \u00eentreaga lume. Procesul a evoluat continuu p\u00e2n\u0103 la ferestrele pe care le \u0219tim ast\u0103zi.<\/p>\n

          Ferestrele cu sticl\u0103 \u2013 un lux<\/strong><\/h4>\n<\/li>\n<\/ol>\n

          Ferestrele au avut \u0219i un rol simbolic \u00een casele umane. \u00cen diferite culturi \u0219i perioade istorice, ferestrele au fost proiectate nu doar pentru func\u021bionalitate, ci \u0219i pentru a reflecta statutul social al locatarilor.<\/p>\n

          La sf\u00e2r\u0219itul anilor 1600, ferestrele cu sticl\u0103 erau considerate un lux. Cei mai boga\u021bi aveau ferestre cu sticl\u0103 doar \u00een camerele cele mai importante. Ferestrele erau at\u00e2t de apreciate \u00eenc\u00e2t aristocra\u021bii care erau pleca\u021bi luni de zile \u00een vizit\u0103 la alte propriet\u0103\u021bi demontau aceste ferestre \u0219i le depozitau \u00een beciuri pe durata absen\u021bei lor. Pe atunci, \u00een Anglia, \u00een Sco\u021bia, \u00een zona Amsterdam \u0219i mai t\u00e2rziu \u00een Fran\u021ba, proprietarii de case trebuiau s\u0103 pl\u0103tesc\u0103 o tax\u0103 deosebit\u0103: taxa pe ferestre. Proprietarii caselor erau taxa\u021bi \u00een func\u021bie de num\u0103rul \u0219i mai ales dimensiunea ferestrelor de pe fa\u021bada imobilului. Cu c\u00e2t ferestrele erau mai mari, cu at\u00e2t taxele erau mai mari. Acest fapt i-a determinat pe unii proprietari s\u0103-\u0219i zideasc\u0103 o parte din ferestrele caselor, pentru a evita plata taxelor excesive. Acesta este motivul pentru care multe locuin\u021be din acea parte a lumii au foarte pu\u021bine ferestre. \u00cen schimb, unele familii bogate au folosit-o pentru a face \u0219i mai evident\u0103 discrepan\u021ba dintre boga\u021bi \u0219i s\u0103raci. A\u0219a au ap\u0103rut locuin\u021be cu mai multe ferestre sau cu ferestre \u201ede form\u0103\u201d, fixate pe exteriorul pere\u021bilor.<\/p>\n

            Sticla cilindru \u0219i sticla float<\/strong><\/h4>\n<\/li>\n<\/ol>\n

            La \u00eenceput, foile de geam pentru ferestre era produse prin \u0219lefuirea \u0219i lustruirea unor cilindri mari de sticl\u0103. Din aceast\u0103 cauz\u0103, produsul ob\u021binut era cunoscut sub numele de \u201esticl\u0103 de cilindru\u201d. Sigur a\u021bi observat c\u0103 sticla din ferestrele cl\u0103dirilor vechi pare ondulat\u0103 iar imaginile sunt distorsionate. Asta se \u00eent\u00e2mpl\u0103 datorit\u0103 modului de ob\u021binere a sticlei. Exist\u0103 arhitec\u021bi care solicit\u0103 \u00een mod expres acest tip de sticl\u0103 pentru proiectele de renovare a cl\u0103dirilor vechi. \u0218i este foarte greu de g\u0103sit \u00een zilele noastre acest\u0103 sticl\u0103.<\/p>\n

            \u00cen 1952, Sir Alastair Pilkington a fost primul care a ob\u021binut sticla float \u2013 sticla care se folose\u0219te ast\u0103zi pentru realizarea ferestrelor. Materiile prime sunt topite \u0219i apoi turnate pentru a forma o foaie uniform\u0103 de sticla. Sticla float a revolu\u021bionat industria, permi\u021b\u00e2nd produc\u021bia \u00een mas\u0103 de foi de sticl\u0103 plate, plane, uniforme \u0219i de \u00eenalt\u0103 calitate.<\/p>\n

                    \u00cen 2015, cercetatorii japonezii au creat sticla cu transparen\u021b\u0103 apropiat\u0103 de 100%, comparabil\u0103 ca rezisten\u021b\u0103 cu o\u021belul de \u00eenalt\u0103 calitate.<\/p>\n

                    Un grup de cercet\u0103tori americani au creat un nou tip de sticl\u0103 folosind un micro-aliaj metalic de paladiu cu fosfor, siliciu, germaniu \u0219i argint, care \u201eplastifiaz\u0103\u201d sticla, f\u0103c\u00e2nd-o mai pu\u021bin fragil\u0103.

Av\u00e2nd doar o singur\u0103 foaie de sticl\u0103 \u00een ferestre, temperaturile sc\u0103zute afectau serios traiul sco\u021bienilor. Din fericire, un sco\u021bian hot\u0103r\u00e2t a inventat un sistem de \u201esticl\u0103 dubl\u0103\u201d care s-a dovedit un mare succes. Primele geamuri termopan cu  2 foi de sticl\u0103, a\u0219a cum le cunoa\u0219tem ast\u0103zi, (cunoscute \u0219i sub numele de sticle termoizolante) au fost dezvoltate de un inginer american de refrigerare la \u00eenceputul anilor 1930.

                        Considerat\u0103 cea mai \u00eenalt\u0103 cl\u0103dire din lume, Burj Khalifa din Dubai, are nu mai pu\u021bin de 24.348 de ferestre. Burj Khalifa, cea mai \u00eenalt\u0103 cl\u0103dire din lume, se m\u00e2ndre\u0219te cu un record impresionant c\u00e2nd vine vorba de ferestre. Cele mai \u00eenalte ferestre din cl\u0103dire sunt situate la etajul 154, la aproximativ 1.823 de metri deasupra solului. F\u0103r\u0103 instala\u021biile speciale cu care este echipat\u0103 cl\u0103direa, ar fi nevoie de 3 \u2013 4 luni pentru ca o echip\u0103 de 36 de persoane s\u0103 cure\u021be \u00eentreaga fa\u021bad\u0103 vitrat\u0103 exterioar\u0103.<\/p>\n

                          Ferestrele reprezint\u0103 \u00een medie 15% din suprafa\u021ba pere\u021bilor exteriori ai unei case<\/strong><\/h4>\n<\/li>\n<\/ol>\n

                          De\u0219i nu este prea mare, acest procent ofer\u0103 totu\u0219i o suprafa\u021b\u0103 semnificativ\u0103 prin care se poate pierde c\u0103ldura din interiorul cl\u0103dirii. Acest fapt duce la facturi mai mari de energie, mai ales dac\u0103 ferestrele nu au geam triplu sau m\u0103car dublu.<\/p>\n

                          Potrivit Departamentului pentru Energie al SUA, 25% din factura medie de energie a unei gospod\u0103rii se datoreaz\u0103 pierderilor de c\u0103ldur\u0103 prin ferestre, luminatoare \u0219i u\u0219i cu performan\u021be energetice slabe.<\/p>\n

                          Dac\u0103 am amintit de Palatul Buckingham, s\u0103 subliniem c\u0103 costurile anuale cu \u00eenc\u0103lzirea palatului se ridic\u0103 la peste 1 milion de lire sterline. Datorit\u0103 statutului cl\u0103dirii, ferestrele nu pot fi schimbate sau m\u0103car echipate cu geam dublu, astfel \u00eenc\u00e2t pierderile de c\u0103ldur\u0103 prin suprafa\u021ba ferestrelor sunt foarte mari. <\/em>Facturile de energie ar putea fi reduse cu aproximativ 15% instal\u00e2nd geamuri cu dou\u0103 sau trei foi de sticl\u0103, realizate din profile cu eficien\u021b\u0103 energetic\u0103 ridicat\u0103.<\/p>\n
