FAQs
What does the term 'double glazing' mean?
The term 'Double glazing' describes a system where air is trapped in between two sheets of glass inside a window frame which forms a barrier of insulation against draughts and noise. In line with Building Regulations, the optimum gap is 16 mm as anything larger is less effective against sound.
What are the main advantages of having uPVC windows, doors and conservatories?
The main reason that uPVC is commonly used is that it is extremely strong and hardwearing, so it performs well in all weather conditions. uPVC is also low maintenance and easy to clean, all it requires is a wipe clean with a damp cloth. It is also less expensive and lasts alot longer then wooden frame windows. Other advantages of uPVC are that it can reduce your heating bills, by reducing draughts it makes your property warmer. It will also reduce outside noise, making your home a more comfortable environment to live in.
Another advantage is that it can potentially add value to your home, as good quality uPVC make your home look more appealing which makes it easier to sell. These days it is an essential feature that buyers look for when choosing a property and the value added to the property can be as much as double what it cost for the uPVC installation.
What does the term 'Low E Glass' mean?
Low E Glass stands for 'low emissivity glass' and is a unique invisible reflective coating that will make the glass more energy efficient. It is energy efficient by reflecting the heat from radiators back into the building, keeping the heat in and reducing your fuel usage. It also lets in light and energy from the sun which is then reflected back into your home. At Hampton Conservatories we use Pilkington K glass as standard, which is categorised as Low E glass.
What does FENSA stand for?
FENSA stands for the Fenestration Self-Assessment Scheme. It exists to ensure that homeowners receive a certificate of compliance from windows, doors and conservatories installers on the thermal performance standards of replacement windows and doors. It was created by the Glass and Glazing Federation (GGF) at the request of the Office of the Deputy Prime Minister in response to the current Building Regulations for the UK. All Hampton Conservatories products have FENSA approval.
What does 'Document L' mean?
Document L is the Building Regulations compliance requirement for England and Wales that sets the standards of energy efficiency in buildings and applies to both new build and replacement windows and glazed doors. It specifies the use of a Low E glass as standard in double glazed units so they may have a low U value and be energy efficient.
Are there different types of double glazing?
Yes, there are many different types. There are many differences between types like, the type of beading used, the structure of the profiles, the types of locking mechanism, the thickness of the glass, the type of seal used, the gap between the panes and whether the glass has any special properties. All these things depend on which manufacturer you trust to supply your windows and doors.
What are the differences between double glazing companies? Are they all the same?
The double glazing industry has a bad reputation for cheap sales gimmicks, poor customer after care and pushy sales staff, so it is important to find a company who dont put pressure on you and one you can trust.
A main difference between companies is the installation and fitting of the product. Most companies will supply similar prodcuts but its the installation service which will set the best companies apart from all the rest. At Hampton Conservatories all our installers are highly skilled professionals and all undertake training to meet the latest standards. Make sure that the company you choose is FENSA registered and that there products have Kitemarks and accreditations with bodies like the British Standards Institute and British Board of Agreement.
