What is A Self-Cleaning Glass


Self CleaningSelf-cleaning glass is a specific type of glass with a surface that keeps itself free of dirt and grime.

The field of self-cleaning coatings on glass is divided into two categories: hydrophobic and hydrophilic. These two types of coating both clean themselves through the action of water, the former by rolling droplets and the latter by sheeting water that carries away dirt.

Hydrophilic coatings based on Titania (Titanium dioxide), however, have an additional property: they can chemically break down absorbed dirt in sunlight. These coatings when exposed to light, a process known as photocatalysis.

Titanium dioxide has become the material of choice for self-cleaning windows, and hydrophilic self-cleaning surfaces in general, because of its favorable physical and chemical properties. Not only is titanium dioxide highly efficient at photocatalysing dirt in sunlight and reaching the superhydrophilic state, it is also non-toxic, chemically inert in the absence of light, inexpensive, relatively easy to handle and deposit into thin films and is an established household chemical that is used as a pigment in cosmetics and paint and as a food additive.

This coating acts to clean the window in two stages, using two distinct properties: photocatalysis and hydrophilicity. In sunlight, photocatalysis causes the coating to chemically break down organic dirt adsorbed onto the window. When the glass is wet by rain or other water, hydrophilicity reduces contact angles to very low values, causing the water to form a thin layer rather than droplets, and this layer washes dirt away. The mechanism of cleaning is illustrated simply in the following four steps;

Titanium-dioxide
1. Conversion of Ti4+ sites to Ti3+ and releasing electrons when UV light (the yellow arrow) shines on the titanium dioxide coating.

electrons
2. These electrons attack to the water molecules (H2O) in the air and convert them into hydroxyl radicals (OH·). These hydroxyl radicals are highly reactive and short-lifetime.

hydroxyl
3. When these high reactive hydroxyl radicals attack the organic molecules, an oxidation reaction occurs and these organic molecules convert into smaller, harmless substances such as carbon dioxide and water.

hydrophilic
4. The hydroxyl radicals also make the glass hydrophilic. When it rains, water molecules spread evenly across it and wipe it clean.

self-cleaningWhen self-cleaning glass has been stored in a warehouse for a long period prior to installation, it may take up to seven days to become fully activated. This is because the activation of the glass occurs via a chemical reaction between UV rays from natural daylight, oxygen and the coating. After then, it will continue to work as long as it’s exposed to daylight, even in dull winter weather.

The Pilkington Activ™ brand by Pilkington is claimed by the company to be the first self-cleaning glass. Pilkington Activ™ consists of a 20–30 nm layer of nanocrystalline anatase titanium dioxide deposited by an atmospheric pressure chemical vapor deposition technique onto soda-lime silicate float glass.

The SunClean™ brand by PPG Industries also uses a coating of titanium dioxide, applied by a patented process.

The Neat Glass™ by Cardinal Glass Industries has a titanium dioxide layer less than 10 nm thick applied by magnetron sputtering

The SGG Aquaclean™ (1st generation, hydrophilic only, 2002) and Bioclean™ (2nd generation, both photoactive and hydrophilic, 2003) by Saint-Gobain. The Bioclean™ coating is applied by chemical vapor deposition.

All You Should Know About Condensation

All You Should Know About Condensation


CondensationCondensation is the passing of a substance from a lighter to a denser physical state. In this instance, water passes from a gaseous (vapour) state to the denser liquid one. Because it is caused by too much humidity, condensation is also the symptom of a more serious problem – excessive moisture at work in your home’s atmosphere.
In seeking cooler, drier outside air, water vapour exerts pressure and forces its way through most building materials. Wood, brick, and drywall are too porous to stop moisture from migrating to the outside. But because window glass is denser and its surface colder than the surrounding walls, vapour is stopped by glass and condenses on it. While glass – the coldest, least porous (and most visible) material in a building – may show condensation first, it may also be noticed on exposed nail heads and other metal surfaces.
Why Does Condensation Occur?
Problems arise because air can hold only a limited amount of water vapour, varying with the temperature. Condensation is related to two conditions always present in the atmosphere inside your home. It is likely to form whenever there is an improper balance between:

Relative Humidity
A ratio between the water vapour in the air compared to the maximum amount that air can hold at a given temperature. For example, 50% means the air is carrying 1/2 of the total water vapour it is capable of holding at that temperature.

Temperature
A particular temperature where the relative humidity becomes 100%, called the “dew point” (see chart). At the dew point, the air is saturated with moisture and begins to lose it in the form of condensation.

Relative HumidityDew Point (Celsius)
20%-4°
30%
40%
50%10°

Condensation* Note: A new home has significant quantities of moisture because of the water used in various areas of construction (700 gallons of water are used in plastering alone for a six room house). This will be eliminated after a period of time.
Where Does Condensation Occur?
In practice, condensation will occur first over the lower part of the window because glass surface
temperatures are not uniform, being lower at the bottom than at the top. Windows with a metal sash usually have more severe problems at the base and sides. Occasionally, it may occur on cold spots, such as nail heads and in corners of outside walls and closets where insulation value is reduced.
Sources of Moisture
The humidity level in a house during the winter will depend on both the moisture added to the air through family living habits (see chart) and the rate at which this moisture is removed by ventilation or condensation.
Quantity of Moisture Added to the Air Through Normal Household Activities

Activity (for a family of four)Moisture in Litres each week
Cooking (3 meals per day for 1 week)6.3
Dishwashing (3 times per day for 1 week)3.2
Bathing (.2 litres per shower)(.05 litres per bath)2.4
Clothes washing1.8
Clothes drying indoors, or using an unvented dryer10
Floor mopping (per 9.3m)1.3
Occupants38
Total Moisture Production per Week63

In addition to the above sources of humidity, such things as gas appliances, dryers vented inside, plants (which put out almost as much water as they receive), pets, humidifiers, damp basements, etc., all increase the humidity level in a home.

Solutions and Facts About Humidity

Solutions

  • Turn off all humidifiers, particularly in homes with forced-air heating.
  • Move plants away from windows (where water vapour will be released directly onto glass).
  • Vent the clothes dryer and gas appliances outside.
  • Do not dry firewood indoors.
  • Ensure kitchens and bathrooms are well ventilated by windows or exhaust fans
  • Ensure that basement walls are kept as dry as possible since they will act as humidifiers when wet.
  • A de-humidifier may have to be installed (Note: a de-humidifier alone cannot eliminate the problem).
  • Do not cover windows with heavy curtains since this will restrict air flow over glass.
  • Produce less moisture inside the house.

Facts

  • Unless indoor humidities are kept below 10%, it is impossible to avoid some condensation.
  • Lower outside temperatures require lower inside humidity levels (see chart).
  • Electrically heated homes are difficult to rectify because there is very little movement of air.
  • Ventilation is generally the most effective means available to reduce humidity and can be done by opening windows, operating exhaust fans and/or installing a ventilator from outside into the cold  air return plenum of a forced air heating system

High Energy Bills

  • High Energy Bills
    As the temperature rises in summer and drops in winter, your heating and cooling bills also do the same. The older windows are vulnerable to leaks and cracks while the newer windows designed to avoid the air transferring in and out of your premises. Almost 25 % of your bill is lost through windows.
  • A Lot of Outside Noise and Dust
    If you can hear a lot of noise from outside which disturbs you, it means the doors are not sealed correctly. It is a good sign to install insulated windows. Tight windows keep out dust, bugs, pollen and sound so the indoor environment is healthier.
  • Difficult Operations
    A window that is poorly installed and got any damage often develops balance issues and make it challenging to lock and unlock the window. Due to safety concerns, you should think over its replacement.
  • Condensation
    If you notice the condensation in between the two panes of glass, it is a sign of defective window seals which require replacement. Energy-efficient windows stay warmer on the interior surface, so condensation would be less, which can eventually damage walls. Less condensation also helps reduce growth of mold.

Chipped Window Frames

  • Soft Or Chipped Window Frames
    When your window frames are chipped or soft to touch, they are likely beyond repair. Smooth window frames even indicate rot and water infiltration. They may start sagging and require replacement.

Simple Tips About Vinyl Windows Maintenance

Simple Tips About Vinyl Windows Maintenance


Windows MaintenanceWe carry the top brands in windows and doors and we're dedicated to protecting your purchase. Below are some tips and instructions for keeping your purchase looking and working like new.

How do I remove stickers from the glass?
The manufacturer stickers should remove easily without leaving any residue. If it does not, wet the glass with soapy water using a sponge or spray. Using a sharp scraper, or razor blade scrape under and remove the sticker. After the sticker is removed use a degreaser to remove any glue left over. Finish by cleaning the glass with the cleaning procedure noted below.

How should I clean the glass on my new windows?
You may clean the glass surface with any commercial glass cleaner or a mild detergent. A soft cloth or paper towel will do the job. If you use a squeegee, please make sure there aren't any metal edges as this will permanently damage the dirt repelling coating and scratch the glass.

How do I clean the vinyl?
Vinyl is easy to clean and never need painting. We recommend wiping with a damp cloth and dishwashing soap in water. Do not use a high pressure sprayer or abrasive cleaning agents to clean your windows and doors. For stubborn dirt use non-abrasive sink and counter cleaning creams or specialized vinyl cleaning agents. Do not use solvents or stripping compounds.

How do I clean the Screens?
Window screens deal with the elements and over time they can deteriorate. Dirt and grime can also build up on your window screens. Simply remove the screens lay it on a flat surface and hose them off with water. Do not use a high-pressure sprayer or any cleaning solvents. Let your screens air dry completely before reinstalling.

How do I clean the Tracks?
This step is important in your annual window maintenance regardless of the type of window you have. The tracks in your windows are prone to moisture, dirt and debris. Using an appropriate cleaner will remove any build up on your windows and keep them functioning properly.

How do I clean the Hardware?
When cleaning your window hardware you should take into account the finish of your hardware. There will be different cleaning procedures depending on if they’re powder coated or plated.

Powder coated hardware should be cleaned with a wet sponge or with soap and a wash cloth to avoid scratching the surface. Always rinse with water afterwards to remove any soapy residue.

Plated hardware should be cleaned with a dry duster or a damp cloth. Make sure to avoid any abrasive cleaners that could potentially damage the surface.

Regular cleaning to remove build-up will ensure that the window fasteners retain smooth operation. WD-40 can be used to lubricate your window locks if they become stuck. Keeping your window hardware clean and maintained will help keep your windows functioning properly.

I have condensation on my windows. Is this normal?
Condensation forms when the inside window surface temperature falls below the dew-point temperature of the room. Condensation on your window surfaces is not an indication that the glass or insulating unit is defective; they simply are doing what they're meant to do. By keeping the warm air in your home the windows also stop the humidity from escaping and that humidity becomes visible on the glass. Poor air circulation in the home, high humidity levels, and temperature are some of the factors that could lead to condensation on your windows.

windowsThe tighter a home is, the more likely it is that humidity generated inside will remain inside and cause problems—unless the home is properly ventilated. But even if moisture levels stay constant, condensation can occur if surfaces get very cold, as they often do in the depths of January nights. Finally, adding moisture to the air will raise indoor humidity levels and make condensation more likely.

Air movement also influences moisture problems. In the winter, the warm air inside the house has a natural tendency to rise. Warm, moist air leaves the house through the attic or the upper story and is replaced by dry, cold air pulled in through the lower level. This is called the stack effect. The stack effect causes moisture problems to be most pronounced in the upper stories of a house. For example, the windows on the lower level may be clear while the second story windows are frosted over.

How to reduce condensation on windows:

  • Lower or turn off your furnace humidifier.
  • Raise the temperature on your furnace.
  • Vent clothes dryers, gas burners, etc. to the outdoors.
  • Don't hang clothes to dry indoors.
  • Use kitchen and bathroom exhaust fans.
  • Open blinds shutters or curtains to allow warm air to circulate around your windows.
  • Don't dry firewood in the house.
  • Repair plumbing leaks and leaky roofs.
  • Ensure that gutters are properly drained away from the house.
  • Seal ductwork in damp basements or crawl spaces especially the ducts that return cold air.

How To Get Maximum Energy Savings From Your Windows

Maximum Energy SavingsWe all want to save money and with energy costs soaring, especially in the winter months, people are always looking at ways to cut those energy bills. Did you know that one of the best ways to do this is to get new energy efficient windows?

Older windows may let in way too much air in the form of a draft. These drafts are cold and cause us to up the thermostat in order to remain comfortable. There are things that you can do short of replacing the window, but they are more of a quick fix than a cure. Weather stripping and new caulking may help temporarily.

Caulking:
When you are re-caulking a window you first need to remove the old and then apply the new. This works best when the temperatures are over 45F and the humidity is low, so before winter sets in is key. For weather stripping you must work with dry surfaces and in temperatures over 20F which gives you a bit more leeway. Both of these applications can block the drafts and help to lower your energy bills.

Storm doors or windows:
Installing storm and/or screen windows can also add insulation to your home and block pesky drafts, however, interior rather than exterior varieties do work better to keep your home warm and cozy.

Blinds:
Another strong option would be to outfit your windows with blinds.  While they don’t have the benefit of holding heat in during the winter they do have the capacity to massively reduce the amount of heat entering your home via the windows during the summer months. In some cases, if you move to purchase high quality Blinds , you can reduce the amount of heat entering your home by 45 percent.

Shutters:
One option that may seem rather old-fashioned (yet highly effective) is to install shutters around your windows.  These come available in either interior or exterior varieties (though one major benefit of the exterior is that it doesn’t detract away from the usable space present within your home).

Essentially these Shutters offer a system by which you can temporarily close-off your window and prevent sunlight from entering and therefore allowing it to heat up and disturb your treated air.

To really improve your energy efficiency and get maximum energy savings though, you will have to replace those old windows. New windows with Low E gas coatings help reduce the heat transfer and the pesky UV rays that can damage carpets and furniture by fading them out. It reflects the heat back to the source which helps keep the home warmer in the winter and cooler in the summer.

New double or triple pane windows also help to minimize those energy bills because there are two or three barriers for the air rather than one which we see with older single pane varieties. New windows fit better, allow in no drafts and are made with better materials than that of their older counterparts. Coatings and configurations are newer and updated and they all lend themselves to being much more energy efficient while significantly lowering those energy bills.

In the summer months we can also save on energy costs by replacing fixed windows with ones that open to allow the cool breezes in which means you may not have to rely so heavily on your air conditioner to keep your space comfortable. Better ventilation and air flow benefits both that bill and our family at the same time, and what can be better than that?
