25 Things You Should Know About Energy Efficient Windows
Facts about the role these simple glass open-and-shut cases play in looks and efficiency in your home.
Benefits Of Energy Efficient Windows:
- If you have leaky and inefficient windows by installing double glazing in an entirely single glazed house you could save the following each year:
|A rated||£130 – £175||£90 – £120||£80 – £105||£60 – £80||£50 – £65|
|B rated||£120 – £160||£80 – £110||£70 – £95||£50 – £70||£40 – £60|
|C rated||£120 – £150||£80 – £105||£70 – £90||£50 – £65||£45 – £55|
These savings are for typical gas heated homes.
- Reduce noise and helps keep the heat in making your home warmer and quieter. The wider the air spaces and the thicker glass reduces the noise level further.
- Is good for the environment as reduces the carbon footprint.
- Reduces drafts and cold spots making the home more comfortable.
- Energy-efficient glazing reduces condensation build-up on the inside of windows.
- Solid Wood: Great insulator against heat and cold, but it’s costly, requires maintenance, and is subject to swelling and warping. Often used in conservation areas where the original windows were timber framed.
- Aluminum/Steel: Strong, affordable, low-maintenance, slim and long lasting.
- uPVC: Long lasting, affordable, low maintenance and can be recycled.
- Composite: have an inner timber frame covered with aluminium or plastic. This reduces the need for maintenance and keeps the frame weatherproof.
10. Low-emissivity (low-E) glass has a thin metallic coating that reflects heat back to its source, keeping heat inside the house in the winter and out of it in the summer. Low-E coatings also reduce energy costs and block UV rays while allowing 95 percent of natural light to pass through.
11. Privacy can be achieved by using special glass treatments such as frosted and pattern glass blocks which allows the natural light in whilst limiting visibility.
12. Glass and frame is rated using an energy rating scheme ranging from A to G – like the one used for home appliances such as fridges/freezers.
13. Very efficient windows use gases such as argon, xenon or krypton in the gap between the sheets of glass.
14. Casement: probably the most popular window choice suitable for new and old properties. Available in a choice of colours, materials, finishes and sizes.
15. Flying Mullion: The flying mullion window is similar to a casement window; but has no obstruction when the window is opened.
16. Picture: These are a shaped window such as small port holes, arches or large circles with a choice of glazing options such as plain, patterned, stained and bevelled glass.
17. Tilt & Turn: Can either opens inwards or outwards from either the side or the top, having dual opening options makes it totally unique to any other window type.
18. Sash: A traditional style window which can have various openings from fixed, double hung and single hung or a combination of these openings.
19. Slider: Suitable for commercial and contemporary properties and useful when a window can’t be opened outwards. The pane of glass horizontally slide pass one another to open.
Secondary windows can be used in a conservation area where double glazing can’t be installed. The secondary pane of glass and frame can be fitted inside the existing window.
20. Window coatings cut glare and energy costs and block UV rays that cause flooring, fabrics, and windows to fade. Window films also provide privacy but do not block the natural light entering the room.
21. Windows make up approximately 10 percent of an average home’s wall space.
22. Manufactures recommend that old windows are replaced every 20 years. Signs of a failing window include broken seals, drafts, rotten or warped frames and condensation.
23. Skylights will provide 30 percent more light than a vertical window of the same size.
24. Glass is easily broken and therefore is a weak spot in your home security. 36% of break-in is through window glass.
25. Glass has been used since the days of the Romans to allow natural light into buildings.
