uPVC Windows Guide

This site is all about uPVC double glazed windows and their advantages.  However there are also disadvantages to a uPVC window in the same way that there are disadvantages to a timber or an aluminum window.  To understand what windows are all about and where a uPVC window fits into the window family, we need to look at the different types of house windows, their description and their different uses, apart from the obvious.  uPVC windows can and have been constructed in all of the forms below.  The following is not an exhaustive list of different windows, and is open to correction from anybody, but we have given it our best attempt.

Fixed windows: Pretty much as they describe themselves – they do not open at any time.  A fixed house window ideal where ventilation is not an issue, but where security is.

Jalousie Windows: These windows are constructed of metal clips and glass slats. These slats can be opened and closed. They are excellent for ventilation and light and due to their shape can be used in places that regular windows would not work as well. Jalousie windows however are not airtight and cannot be made airtight so they are impossible to seal.

Casement Windows: Window sashes opening on hinges that are generally (but not necessarily) attached to the upright side of its frame.  These windows open outwards as against sash windows, which slide up and down.  Casement windows are better in situations that are harder to reach as sashes can be difficult to open unless you are positioned properly.

Gliding Windows: Gliding windows for houses are windows that slide laterally rather than open outwards.  As they do not open outwards, they do not create an obstruction in an area of limited space.  However they can be more difficult to seal with regard to insulation than other windows.

Sliding Windows: Similar to gliding windows and with the same advantages.

Awning Windows: These are window frames that have one or more sashes hinged at the top and swinging outward.  These windows are specially designed for the purpose of providing light and usually can be opened by swinging out the sash.  They allow in a lot of light and air when they are positioned properly.  They are also to be considered when privacy is to be desired.

Palladian Windows: These are windows in the form of a round-headed archway, containing a single double-hung window, joined on either side by a double hung narrow window.

French Casement Window.

Picture Windows: These are large windows, which dominate the room, and which often are designed to present an attractive view.  They are an excellent light source but could be expensive to repair if broken.  Picture windows do not open, so can not be depended upon where ventilation is a requirement.

Windowscapes: ‘Windowscape’ is used to describe an entire wall made of windows.  The views are fantastic and so obviously, is the price.

Single Hung Windows: Single hung windows open by sliding up and down like a sash window, but with the top half being fixed.

Double Hung Window: A double hung window is a window that the top portion can be opened while the bottom remains closed – They are chosen for their style and excellent ventilation ability. Also they are popular for safety reasons, for example in children’s bedrooms, because they allow in adequate ventilation, while helping to prevent any accidents.  They are also popular in kitchens for ventilation reasons.

Hopper Windows: These are casement windows for houses with a sash hinged at the bottom.  Hopper windows open inward and are excellent for ventilation.  These windows are usually used in basements.  Can be difficult to work in with curtains and blinds due to the fact that they open inwards.

Rotating Windows: These are house windows that have a centre pivot that enables them to open from either side and top or bottom. One of the main advantages of rotating windows is ease of cleaning.

Bay Windows: Bay windows are contained in an alcove of a room and these windows have glazing to 3 sides so they can catch the light from some angle, during a most of the daylight hours.  They have a style that adds to any residence and as well as being able to receive sunlight from many directions, they also have excellent views. They are most useful in the living areas of a home where views can be most appreciated.

Bow windows: They are similar to bay windows but with less radical angles.

Oriel Windows: Oriel windows are also similar to bay windows, but they are supported by brackets underneath and as a rule they are much smaller than bays.

As I have said, this is not a complete list of all types of house windows, but it will assist you in considering the best option open to you when you are designing a residence, or thinking about replacement house windows for your home, attempting to compare house window prices, or trying to decide between aluminum timber or uPVC windows.
