By reducing condensation risk internally, double glazing aids in reducing dampness or humidity inside the home, especially when the inside of your dwelling enjoys a regular heating cycle and has balanced adjustable background ventilation
This is partly because a double-glazed unit's internal glass panel has a temperature that is closer to that of the room. This lessens the effect of internal air reaching its dew point and depositing water on the object that is the coldest, which is typically the window, which happens frequently with single-glazed units.
Tip 1. Before buying your double glazing make sure that the inner pane of an energy-efficient double-glazed unit includes glass such as Pilkington energiKare™. The coating reflects heat back into the room whilst also letting in free heat from the sun, known as passive solar gain -a real game changer!
Tip 2. Make sure your windows have either discrete or adjustable trickle vents fitted that allows you to provide some low-level adjustable background ventilation into your rooms without opening up your window units – and possibly reducing your security.
Tip 3. You need to buy the best thermally performing window and door units, which are also secure at the lowest price.
Tip 4. Makes sure windows at first-floor level open fully and are suitable for means of escape purposes - check that with your competent person supplier
Noise reduction -abatement
Double glazing can work well as a noise barrier, although it is not designed to sound insulate your dwelling. This sound insulation improvement which is certainly better than single-glazed windows is especially appealing and can significantly raise the quality of life for residences near built-up areas or busy roads.
Improving your window and door’s thermal insulation performance is the reason many homeowners see as an immediate benefit.
Double glazing increases the security of your home because it is harder to break. Additionally, it can serve as a deterrent to any potential intruders searching for a simple target.
Increases the resale value
In the event that you decide to sell your house in the future, a buyer will likely be drawn to a home that is energy efficient. In some circumstances, it might even raise your house's resale value.
Is Double Glazing an investment?
The installation of double glazing in your home should be considered a long-term investment because you might eventually experience significant energy cost savings. A warmer, quieter environment will result from the installation, improving your quality of life and the resale and aesthetic value of your home.
It's crucial to obtain and evaluate several double-glazing quotes. The cost and the calibre of the windows that each installer offers will vary. The best way to ensure you get the best quality at the best price is to compare quotes from both national and independent suppliers.
How does the competent persons scheme benefit you? What is it?
A company installing new windows in your home is required by law to make sure that the installation complies with established government standards.
It is always recommended to use a trader who is registered with the Competent Persons Scheme when choosing a company to install or replace double glazing.
The competent persons scheme was instituted by the UK government as an alternative to the demand for submitting a building notice / Initial Notice with a building control body. It enables businesses to "self-certify" that their construction work complies with building regulations established by the government.
Using a person or company under this scheme has a distinct advantage: You won't have to pay for the inspections required under building regulations, and you won't have to submit the work for inspection to your building control body.
You will receive a certificate once the work is finished to prove that your new windows or doors meet the necessary standards (thermal performance). If you sell your house in the future, you will need to show or give your purchasers the window certificate as part of their home pack information, especially if the windows benefit from a long warranty.
