Old Window of House

Benefits Of Modern Double Glazing Windows

Double glazed windows are windows with sealed inert gas in between two glass layers. They have properties that enable them provide insulation twice as much as single glazed windows. They can easily be fitted in older or new homes as well as in commercial properties.
The following are some of the benefits of modern double glazing windows;

Modern Window

I. Cost of Energy

Double glazed windows are used for thermal insulation as they reduce the flow of heat movement (incoming and outgoing), what results is less energy for heating or cooling the house. The more the glass layers, the more the insulation as each layer traps a good amount of heat that passes through increasing protection against heat loss.
Reduced heat loss means less usage of the heating system thus lower energy consumption and reduced power bills. They are also draught proof and this can save a significant amount of money which could have otherwise been spent in draught proofing. Also, low maintenance costs after installation and long lifespan leads to increased savings.

II. Reduced damage to furnishing

This is because double glazed windows reduce the amount of UV light that enters the room. When the heat from the sun is extreme, it can damage in-house furniture, fittings, carpets and paintings.
Minimized UV light transmission reduces interior fading to up to 95%. Laminated and Tinted glass also offers similar benefit (of reducing the UV light penetration) but with reduced clarity to external views. With Double Glazed Windows, thermal drapes that block the exterior view from inside the house are no longer utilized.

III. Improved Security

Compared to other types of windows e.g. Single Pane, Double Glazed Windows are hard to break.When broken, the shards stay intact resisting penetration thereby discouraging intruders and making them a good option for increasing security to your home. The security feature can further be enhanced by incorporating toughened glass in double glazing units.
Consequently, since they are sealed tighter and fitted with safer, stylish hi tech locking systems, opening them from outside is not easy. Thus very effective protection from break ins.
A superior, stylish and improved security windows system with PVC fittings is maintained.

IV. Sound Insulation

This is because of the barrier created between the inside of the house and the outside environment.
Double Glazing works by diluting noise as it passes through the two layers of glass and through the inert gases. This process is very effective and an encouraged investment for those who live in cities, by a busy road/street or beneath a flight path, as it reduces up to 70% of the noise from outside ensuring a calmer, quieter home.
Noise, due to its wave properties can pass through windows by;

  • Vibration; allows easy sound travel through solid objects.
  • Poor seals, cracks or spaces; after entry, it amplifies inside.

High sound levels and noise can inhibit concentration, reduce sleep, cause headache and make one lose the sense of hearing. To prevent these, measure of control must be enforced.
Double glazing windows prevent sound penetration by the above two ways since they are heavy enough to reduce vibration and exhibit minimal air infiltration.
According to research and statistics, the noise reduction effectiveness is also enhanced by the large buffering air cavity that exists between the two glass layers.
The distance between glasses provides depth to the air cavity. The larger the depth, the more sound is insulated.

V. Reduced Condensation

When moisture lands on a warmer surface, it condenses to water droplets which in turn freeze to frost. Frost makes the room colder by lowering the temperatures inside. The inert air between the two layers of glass and the airtight seal blocks up moisture in the cold weather preventing condensation process (even in bathrooms).
With Double Glazing therefore, an improved thermal insulation is exhibited thereby greatly reducing the condensation process maintaining a warmer, drier home.
In older homes, Condensation can cause mould and mildew, damaged window frames and timber rot which can eventually cause adverse health effects. Double Glazing mitigates these effects by reducing excess moisture that collects on window panes

VI. Cold Summers

Heat into the house from sunlight travels via the following methods;

  • Convection; heat transfer by air currents where warm lighter air rises displacing denser air or ‘forced’ convention through breeze. Both processes can also take place concurrently.
  • Conduction; heat travels via a conductor e.g. aluminium or steel among others.
  • Radiation; heat travels directly from the sun

To prevent or reduce the above heat transfer processes during summer, double glazing windows exhibit a low Solar Heat Gain Coefficient (SHGC)to reduce heat effect from direct sun-rays and low u-value that prevents light heated air outside the room from moving inside and cool air inside from escaping through the window.Also trapped heat energy reduces the burning effect through windows in hot sunny days.
Compared to Single Glazing, Double Glazing can reduce solar heat through windows by up to 20%.
Argon filled units and Low-E glass, which contain higher thermal properties can reduce solar heat by up to 50%

VII. Warm Winters

Single Glazed Windows lose up to 70% of heat. As insulators, the depth of inert gas between the two layers of glass prevents cold temperatures from affecting the warm temperatures already existing in the house.
Other glasses superior for this role include; argon filled units and Low-E glass.
During winter, high Solar Heat Gain Coefficient (SHGC)properties enables the windows to allow the heat from the sun be transmitted into the house by convention, conduction or radiation and low u-value prevents the warm heat in the house from escaping.

VIII. Resale value

A home fitted with double glazing windows has an enhanced resale value. Home buyers want homes with sufficient insulation material and these windows make the house even more desirable to house purchasers. They give an old home a better modern look.

IX. Maintenance Costs

After fitting, Double Glazing Windows last for a very long time when still in good initial condition without additional maintenance.Consequently, they are impact resistant therefore don’t break easily, are not affected by strong UV lights, are not affected by termites, they do not undergo warping and no corrosion or paint is needed. All these save on time as a resource, effort and money.

X. Resistant to adverse weather conditions

This property makes them important for use by those living near large water bodies. Double Glazing Windows are not affected by heavy winds, heavy rains and salty air or water. Brocken glass tends to remain intact, still protecting from wind and strong UV light for replacement at a later, more convenient period.

XI. Improved Privacy

This is by the use of tint glass on double glazing creating a darker look, slightly difficult to see through.

XII. Environment friendly

Double glazing ensures more heat is trapped inside the house for longer periods. Thermostats and other room heat heating appliances are kept off leading to lower or no carbon emissions into the environment.
As per research, a three bedroom house with ‘A’ rated windows saves more than 700 Kgs of carbon dioxide gas in a year.
Consider all the above benefits of double glazing windows and enjoy long run reduced costs, improved authentic appeals summed up by comfort, fulfilling and a more relaxing temperature controlled environment,
