Low E (Emissivity) Glass is essentially a glass panel with an internal film. Manufactures claim that E Glass significantly reduces UV radiation, thereby protecting furniture, flooring etc. Other claimed benefits include improved insulation and a reduction in sound transfer.
An alternative to Low E Glass is double glazing and clearly a number of factors need to be considered, with cost being a key issue for most.
As a window cleaner in Perth I have the pleasure of cleaning many large beautiful homes with significant feature windows that attract high levels of heat and radiation. Many of these properties are coastal with terrific panoramic views and to maximise these views and to achieve a more modern look many of these amazing windows do not have window coverings.
You can therefore see the appeal of utilising low E Glass or double glazing to reduce the level of radiation penetrating the home.
In terms of cleaning Low E Glass there a few things you should be aware of:
- The internal film can be scratched fairly easily so care needs to be taken when cleaning it.
- If a squeegee is used (and I am aware of a manufacturer that advises against this) the internal film can create a significant drag on the squeegee. Some window cleaning groups may charge more if they feel it is more time consuming to clean.
- Certain types of E Glass may have a slightly milky look when the sun is shining directly on the panel even when it has been properly cleaned.
Handy to be aware of the above points when discussing with your window cleaner. Team Window Clean is always happy to provide a free detailed quote that incorporates your unique window cleaning requirements.
