PROFILES
JMegrame has been producing plastic windows, doors and multiple glazedunits since 1992. Modern GEALAN (Germany) system profiles ofpolivinylchloride (PVC) are used. Both technical parameters and appearanceof the profiles meet the high quality requirements of today’s windows. Theproducts are characterised by durability and longevity, they do not rot,burn or react with chemicall active environment. Excellent heat insulationproperties of plastic profiles make them very economical in terms of energycost saving. The heat conductivity coefficient of the new type profiles is1,3 W/m2K. The profile system is impervious both to moisture and dust. PVCprofiles are resistant to mechanical impact: they neither crook nor break.The properties of polivinylchloride enable to produce windows and doors ofa wide diversity of sizes, forms and colours. Colour profiles are producedby coating them with acryl. You maycreate your own colourful environmentsince you are absolutely free in choosing from our palette of colour.[pic][pic][pic]

MULTIPLE GLAZED UNITS
Highest quality Pilkington glass from England is used for glazing plasticwindow units. Float technology is employed in producing this glass,resulting in a very even glass surface and excellent transparency. Theglazed unit is sealed by the sulphide and butyl methods thus obtaining therequisite properties of the multiple glazed unit – impermeability andmobility of lass. To improve heat insulation properties of the glazed unit,glass of various thickness as well as special K glass is used. The glass ishighly resistant to breaking and fire and provides anti-burglar protection.Toned or reflection glass protects premises, furniture and wall finishing
against negative effects of sun.At present most of multiple glazed units are made of Pilkington glass withsoft selective coating, the chambers being filled with inert gas.Therefore, the heat conductivity coefficient 1,1 W/m2K is achieved. Suchmultiple glazed unit meet the latest requirements and are widely usedthroughout Western Europe.Pilkington glass provides excellent sound insulation. Various combinationsof glass enable to design sound insulation according to specific noiseconditions. Multiple glass units are characterised by long service life. Ithas been estabkished by investigations that they may serve for as much as80 years.[pic][pic]ACCESSORIES
Megrame offers a wide range of accessories that match both functionally andestethically. Regulated fixing devices allow ventilating rooms withoutleaving the windows open. They prevent formation of vapour condensate andserve as a heat saving measure during cold seasons of the year. This is acheap solution of ventilation problems in the premises having no separateventilation system.Air vents – small ventilation windows serve as another heat-saving measure.
Internal windowsills. Windowsills of various colours offered by Deceuningmay be matched with other details of the interior. They are moistureresistant and fine in appearance, and are made of healthy materials (do notcontain formaldehydes). The windowsills are very durable due to specialreinforcing rib inside. Their maintenance is easy, with no paintingrequired.External windowsills. External windowsills of aluminium or steel plastisol-coated sheet and therefore are highly resistant to temperature changes,direct sunlight and acid rains. 4. The customer ordering these windowsills may choose from a range ofcolours. We also offer door spring-pulling units, external door handles,and mechanisms for opening transom windows

THREE-CHAMBER PROFILE
[pic][pic]
1. The dual seal system with APTK rubber seals is long lasting and requiresno maintenance whatsoever.
2. The strong profiles allow the use of glass as thick as 48 mm, meaning
that soundproof glass that meets the strictest requirements can be used.3. The Quality. Many profile ridges and the increased profile depth of 62mm stabilise the profile and improve the overall rigidity of the windowframe.
4. Stability. The large main chambers in the profile can also be reinforcedwith galvanised steel profiles. Alternatively, aluminium reinforcements andwelded corner pieces can be used in front door units. The sizes are gearedto static requirements.

FIVE-CHAMBER PROFILE
[pic] S 7000 IQ – THE NEW WINDOW SYSTEMQ
Modern windows are characterised by increasingly better heat insulationproperties. Excellent heat insulation characteristics of multiple glazedwindow units have been achieved – k= 0.75 W/m3K. In Germany, the standardheat conductivity coefficient for multiple glazed units in new dwellingconstruction is k=1.1W/m2 K.
The necessity of energy saving programmes is mainly determined by: energycosts and requirements to minimise emissions to the atmosphere (to mitigatethe negative consequences of global warming). Heat generating plants areone of the largest polluters of the atmosphere. Both the USA and the EUMember States are going to implement strict plans for the reduction of heatgeneration.The production of particularly warm windows is developing along two lines:– multichamber wider frames have appeared on the market (with thetraditional 50-60 mm profiles very high heat conductivity parameters cannotbe achieved);– some producers return to a double glazed window unit, however, inaddition to the float-type glass, two glasses treated with soft selectivecoating are used.The novelties of this window system include:1. Much improved profile thermal parameters A certificate issued by the Rosenheim Window Institute for this profile system states the heat conductivity value k = 1.1 W/m2 K. This has been achieved upon increasing the profile width up to 74 mm (the width of GEALAN’s 3000 system profile is 62 mm). Instead of 3 chambers the new profile has been divided into 5
chambers. 5-chamber profiles have already been included in the range of GEALAN’s profiles but the new system allowed to increase the width of the chambers themselves, which resulted in much better thermal parameters of the system. Better parameters are also due to changes in steel reinforcement: the steel structures used to reinforce the profile due not contact the plastic chamber walls throughout the structures’ area, which minimises the effect of steel as a temperature bridge.6.
2. Self-ventilation system. GEALAN has a patented self-ventilation systemGECCO which, depending on the wind strengh, opens or closes a special flapin the window leaf.
3. Improved protection against burglary. This is also possible owing toincreased width of profile in this system. Durability is lent to theprofile by the peculiarities of frame and leaf design, stronger hollows forthe installation of fittings, increased mechanical resistance of steelreinforcement and the technology of installation of window posts.
4. Modern design. The system is characterised by particullarly soft formswith rounded edges. The height is very small in relation to the wideprofile: the visible part of the leaf is just 39 mm, which makes the windowespecially elegant.

5. New profile width ensures excellent soundproofing. The design of thesewindows allows using multiple glazed units up to 40 mm thick. This enablesto produce windows for a broad range of applications.MEGRAME has already introduced all the above-mentioned novelties. It wasthe first in Lithuania to start the production of multiple glazed unitswith soft selective glass. The first windows of this type have already beeninstalled in the Vilnius Santariskes University Hospital.The new quality, however, increases prices for new products. MEGRAME, whichboasts high production volumes and devotes much attention to pricing, hasachieved that the employment of the new system would not increase productprices excessively.
The new window system will co-exist with GEALAN 3000. They complement oneanother, extending the window manufacturers’ possibilities to offerquality, reliability, and excellent design to their customers.7.
WOODEN WINDOWS
We produce wooden windows, store windows and balcony doors using only thehighest quality wood material from the Nordic states and employing advancedGerman technologies.Production takes place in modern shops of UAB Megrame Medis company. Theproduction equipment of new generation has been designed according to theprojects of Michael Weining AG and Hess Technology, leaders of woodprocessing technologies in Germany. The company’s staff, including machineoperators, were trained by foreign specialists.State-of-the-art technologies allow producing windows and doors of variousforms. Tools supplied by the German firm Leitz ensure accurate and highquality processing of the wood surface. A new generation window profile IV-69 with larger than normal roundings and inclines was selected. This lendsspecial elegant appearance to the products. The possibility to install oneor two seals and the use of Pilkington single- or double-glazed glazedunits guarantees the desired level of heat insulation and soundproofness.We may also design and produce anti-break-in windows and doors.Rhenocoll and Sikkens impregnation, priming and painting systems are usedfor the window finishing. Due to deep penetration they provide qualityprotection against the atmospheric effects.
The palette of paints and varnishes allows to obtain the desired coloreffect, at the same time preserving the natural beauty and warmth of wood.
Ironwork supplied by the German manufacturer G-U is used for our windowsand doors, therefore the windows may be opened, half-opened, sloped, slidand folded. Various small ventilating windows may used.
The external horizontal surfaces of frames and leaves are covered withprotective aluminum flashings.

INSTALLATION
A good window is the window that has been properly installed.
Around 70% of customer claims (both in Lithuania and in developed Europeancountries) are connected with installation errors, not with poor quality ofthe windows themselves.
MEGRAME was the first in Lithuania to prepare a window installation manual
based on its own experience of many years and on the materials of studiesconducted by the Rosenheim Window Engineering Institute and the Germanconcern Gealan Werk. The manual is intended for everyda The manualidentifies the problems of installation of plastic, aluminium and woodenwindows and their structures and provides recommendations for the solutionof these problems. The situation on site often appears to be different fromwhat was planned and then the installer must look for optimal solutions.Making of connections is related to various problems of constructionphysics, design and engineering. The causes of connection problems are,roughly speaking, 70% planning errors and 30% installation errors.The publication has been agreed upon with the Lithuanian Union of CivilEngineers and registered with the Ministry of Environment.In case this manual does not provide answers to the questions you areconcerned with, we will gladly consult you individually work, with itsformat making it convenient for carrying.
