Double Glazing Sydney Low Maintenace

We have been the premier choice for supplying new and replacement windows with an innovative range of low maintenance, high quality uPVC windows and doors to intelligent consumers who appreciate superior performance. Our Double Glazed Windows and Doors not only merely meet the minimum requirements of building standards, they exceed them with a large performance margin, and contribute to a long trouble free life.

Low maintenance feature of our uPVC Double Glazed products is due to the inherent qualities of upvc that make for ideal use as a frame material: durability, corrosion resistance, thermal insulation, tensile strength, weather resistance. In addition, advances in science have allowed us to integrate UV protection that is necessary for the harsh Australian sun, to ensure many years of attractive appearance. Upvc used for window frames is harder than wood and will not leak or rot unlike timber windows. The corrosion resistance of upvc to most chemicals, but in particular salt - make them ideal for coastal applications, as an alternative to aluminium which is known to be easily damaged, not only the frame but the hardware, making them hard to operate.

Upvc will never need to be oiled, chemically treated, sanded or polished. You may wish to clean the glass regularly with a glass cleaner, but not more often than you would otherwise have! The actual frame will not ordinarily require thorough, laborious cleaning (vandalism excepted). Commonsense approach is sufficient for trouble free operation eg watch out for obstruction to operation such as leaves, debris, pebbles etc near the doorway or inside the frame; trees or construction materials that may scratch the frame; avoid children's stickers or art and craft material on the frame.

Ordinarily, we would recommend either water or a very mild detergent, for tougher stains, contact us and we can assist with an appropriate cleaning solution or method. Although it is fairly easy to remove foodstuffs, crayons or dirt, deep scratches are not easily fixed, so you should avoid this when moving furniture etc. We have designed our basic option of the standard white coloured profile to be the same colour outside as inside, so the scratches won't be obvious.

The profile is designed for a long lifespan, which extends beyond the standard industry warranties, and since it will never rot or corrode, it has proven to be much better as a frame material, than aluminium and wood. We use premium-extruded vinyl, which prevents the peeling and pitting of window frames, sometimes evident in cheap Chinese imports. The sloped design, waterholes and weather-stripping protect from infiltration of water and air. Upvc is also self-extinguishing and non-combustible, so it is appropriate for use in bushfire risk zones. Even our basic handle & lock secures the window at multiple points for improved security. In addition, our commitment to sustainable manufacturing practices and our environmentally friendly credentials make upvc double glazed windows and doors even more attractive to the green consumer. Low maintenance, energy efficient products will be the driving force of the building & construction industry in the future, so put yourself at the fore-front of new developments in technology and save the endless list of problems that have been known to plague users of aluminium and wooden windows!

Windows made from wood are unfortunately subject to joint failure. The only effective preservative applied to frames was lead based, but knowing the dangers of exposure to lead, it is no longer used. Organic preservatives, although available are unstable, and while traditionally window joints were mortice and tenoned, where parts were soaked in lead primer then assembled, now they are glued. Wood is notoriously good at absorbing water, and together with joint failure results can be rotten and inoperable windows or doors.

Common client complaints about their former aluminium windows were that they were difficult to open, that the window leaked or was draughty, distortion to the window frame, loose screws/ rivets or brushes, rusty frames and/or hinges with powder residue and many more. Why would you go through the trouble and expense of fixing such windows when there is a better option? Upvc Double Glazed Windows and Doors require the least maintenance than aluminium or wooden framed windows and doors.

Our Upvc Windows and Doors are ecologically sustainable in many ways: they are 100% recyclable; the non-lead stabilizers make the profile safe for children (upvc products even have medical applications in neonatal care), save energy and carbon emissions by being thermally efficient; do not contribute to deforestation or alumina smelter pollution. Research shows that the most promising potential for lowering environmental impacts of windows is expected to be through the optimisation of the design and specific construction processes, which means increasing the quality of the windows with respect to their main function of saving heating energy in the use phase (e.g. lowering the specific heat loss). Raising the amount of secondary material used, or lowering the amount of material required for the same function, may be another ground for optimization of the constructions.   Get all the facts on double glazed environmentally friendly

For windows and doors that do more than just open and close, but actually work for you to reduce your household or office energy bill by utilizing an energy efficient profile system and double glazing.

Window Factory Double Glazed Windows and Doors exceed expectations in many hostile environments that are not suitable for other types of materials. Due to the unique properties of upvc, the frame maintains high tensile strength and modulus over a moderate temperature range, low thermal conductivity, and excellent chemical and corrosion resistance to a variety of aggressive substances. In general upvc has good acid and alkali resistance as well as excellent vapour barrier properties and excellent UV resistance. Upvc frames provide many construction advantages due to the material's inherent corrosion resistance, lightweight, ease of fabrication, and other labor-saving characteristics. In addition, upvc frames are high precision and can be manufactured to a tolerable value of +/-3mm, which is ideal for demanding architectural applications.   Greater detail on double glazed corrosion resistance can be found here

We only use quality extrusion that has been rigorously tested for UV radiation in harsh environments in desert or mountain conditions.

There are significant savings in electricity that will pay for your windows in 6-7 years and will reduce your CO2 emissions by about 100-150kg per year. For an indication of energy efficiency of a window or door, look for the U-value or R-value. U-value measures the overall heat transfer coefficient, or how well the window/door conducts heat and is also the inverse of the R-value. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value. Our windows boast a value of 1.8, which means they perform three times better than an aluminium framed window with a typical value of 5.4-5.6. And since windows can contribute to between 15-40% energy loss in a building, installing the most energy efficient windows available should be the intelligent homeowner's priority.   Get all the facts on double glazed draft proof

Ordinary tinted glass is popular because it reduces heat gain and carbon emmissions, although it also marginally reduces visible light transmission. High Performance or Low-e tinted glass or spectrally selective tinted glass reduces solar heat gain to below that of ordinary bronze/ gray tint but has a visible transmittance closer to clear glass. The tint has little effect on the U-factor but reduces solar gain considerably, which can reduce the need for air conditioning in the summer. Tinted glass is useful in controlling glare - especially for those windows facing east or north east. Return the sunlight not glare into your home.   For a detailed discussion on the subject of double glazed tinted glass click here

Low-e glass brings out the best that technology has to offer for improving your views and comfort! A cool, metal oxide coating is applied to clear or tinted glass, so that the appearance and performance are the same regardless of glass thickness. Low-e glass is recommended by many energy efficiency experts as a result of high performance combined with aesthetics. Low-E glass typically cost about 15% more than ordinary glass, but they reduce energy use by as much as 30-50%, by using most of the heat gain in winter but keep the harmful UV rays out during the summer, and when used in insulated glass units - can have even better benefits.
For hot climates, low-E coating should be applied to the outside pane of glass. If the windows are designed to provide heat energy in the winter and keep heat inside the house typical of cold climates, the Low-E coating will maximise benefit by being on the inside pane of glass.   More info on double glazed low e glass
