Window Configuration and Shape – From Bay window to Picture Window

Sustainable Construction Services supplies double and triple glazed windows in every possible shape and configuration. Some configurations are extremely beneficial to provide thermal and acoustic insulation, security, safety, structural strength and other properties. Other windows serve a certain design approach. Not every window type is available in every material; however SCS will source the window type for you if it is manufactured in Germany, central Europe or Australia. The window types also differ from each other regarding the accessories and options they are available in as well as handle types that can be fitted.

Shapes

Our suppliers are capable of manufacturing windows to every architectural requirement. All thinkable shapes and designs are possible, for example round windows, arched windows, corner windows, triangular and trapezoid shaped windows, pentagonal windows, hexagonal windows, octagonal windows and many more. SCS looks forward to any request of a special shape.

Window shapes, double and triple glazed

Types

Please see below the window types that can be supplied by SCS with an explanation of their benefits and disadvantages. Benefits and disadvantages are based on quality double or triple glazed products and proper installation methods and materials to be used (which is unfortunately not often the case)!

Fixed

Fixed Window - double and triple glazedGenerally, a fixed window cannot be opened. The function is limited to allowing light to enter as well allowing vision to the outside or between areas within a building perimeter. Panorama (or picture) windows are normally fixed, allowing an unobstructed view to the outside at wide angles. This type of window is used in situations where light or vision alone is needed as no ventilation is possible through fixed windows without the use of ventilators. Transom windows and bay windows are also fixed in many applications.

Advantages: Great thermal and acoustic properties (Seals well against air exchange between outside and inside of the building); very secure and safe;

Disadvantages: Ventilation not possible (unless glazing, frame ventilators or other ventilators are used), Cleaning is often complicated and expensive, especially on upper floors

 

Single-hung sash (vertical sliding)

Single hung window - double and triple glazedThis type of vertical sliding window consists of one sash is movable (usually the bottom one) and the other fixed. This is the earlier form of sliding sash window, as it is traditionally cheaper than double hung windows.

Advantages: The window serves certain architectural design approach. They only occupy the plane in, which they move, when opening.

Disadvantages: Thermal properties are OK, but often not great, as the pressure on the seals is low and decreases over time (allows air flow sometimes water penetration, when closed). Acoustic properties are often worse than for other window types. Cleaning of upper glazing unit from outside is complicated and expensive. Security of most systems is inferior (slightly better than double-hung).

Double-hung sash (vertical sliding)

double hung window - double and triple glazedThis sash window is the traditional style of window in the United Kingdom, and many other places that were formerly colonized by the UK. With two parts (sashes) that overlap slightly and slide up and down inside the frame. The two parts are not necessarily the same size. Currently most new double-hung sash windows use spring balances to support the sashes, but traditionally, counterweights held in boxes on either side of the window were used. These were and are attached to the sashes using pulleys of either braided cord or, later, purpose-made chain.

Advantages: The window serves certain architectural design approach. They only occupy the plane in, which they move, when opening.

Disadvantages: Thermal properties mostly not great, as the pressure on the seals is low and decreases over time (allows air flow sometimes water penetration, when closed). Acoustic properties are often worse than for other window types. Thermal properties further decline, when seals wear out. Cleaning from outside is complicate. Security of most systems is inferior.

Sliding  window (horizontal sliding)

Sliding window - double and triple glazedThe sliding window has two or more sashes (sometimes one only) that overlap slightly, sliding horizontally within the frame.

Advantages: The window serves certain architectural design approach. They only occupy the plane in, which they move, when opening.

Disadvantages: Thermal properties mostly not great, as the pressure on the seals is low and decreases over time (allows air flow sometimes water penetration, when closed). Acoustic properties are often worse than for other window types. Thermal properties further decline, when seals wear out. Security of most systems is inferior.

Casement window

Casement window - double and triple glazedA window with a hinged sash that swings in or out like a door comprising either a side-hung, top-hung (also called “awning window”), or occasionally bottom-hung sash or a combination of hese types, sometimes with fixed panels on one or more sides of the sash. Handing applies to casement windows to determine the direction of swing; a casement window may be left-handed, right-handed, or double. The casement window is the often found in the UK, Australia and parts of Europe.

Advantages: The window can have good thermal and acoustic properties can be achieved, especially when pressure on the seals is created and seals are applied all around. Depending on frame, locking system and glazing, good security can be achieved. Cleaning from the inside is easy and saves cost.

Disadvantages: For outward opening casement windows, installation of shutter systems, blinds might be complicated. For inward opening windows they will take some space up in the room and use of window coverings (curtains/ blinds)can be restricted.

Awning

awning window - double and triple glazedAn awning window is a casement window that is hung horizontally, hinged on top, so that it swings outward like an awning.

Advantages: Windows can be kept slightly opened for good ventilation and air quality.

Disadvantages: Awning windows are normally does not open completely, which reduces ventilation and complicates cleaning. Thermal insulation is often low (especially for larger windows) as the single locking point puts insufficient pressure on the seal (this can be reduced if additional points are added). Security is compromised on most windows.

Hopper

A hopper window is a bottom-pivoting (top-hinged) casement window that opens by tilting vertically, typically to the inside (Mostly used for schools and other public buildings).

Tilt and slide

Tilt and slide window - double and triple glazedA tilt and slide window has an operable sash tilts inwards at the top (function used mainly for ventilation). The tilting sash can also slide horizontally past the fixed pane.

 Advantages: Tilt & Slide windows usually have great acoustic and thermal properties, as the locking system applies high pressures on the seals and allows for structural integrity and stability. Highest security and safety standards are often achieve, due to locking system, functionality and structural capabilities. They only use the plane in which they are opening and do not use space in the room excessively. In tilt function, constant ventilation and therefore air quality is created.

  Disadvantages: Initial adjustment needs to be done by a competent individual.

 

 

 

Tilt and turn

Tilt and Turn window - double and triple glazedA window which can either tilt inwards at the top, or can open inwards hinged at the side (single sash is capable of both functions). This is by far the most common type of window in Germany (its country of origin), also common in central Europe, Scandinavia and other countries.

Advantages: Tilt & Turn windows achieve highest results fort acoustic and thermal insulation, as the operating and locking system applies high pressures on the seals and allows for structural integrity and stability. Highest security and safety standards are often achieved, due to locking system, functionality and structural capabilities. In tilt function, constant ventilation and therefore air quality is created.

Disadvantages: Initial adjustment needs to be done by a competent individual.

Transom

Transom window - double and triple glazedA window above a door; in an exterior door the transom window is often fixed, in an interior door it can open either by hinges at top or bottom, or rotate on hinges. It provided ventilation for forced air heating and cooling. A fan-shaped transom is known as a fanlight.

Advantages: Good for permanent ventilation, daylight penetration and vision to the outside.

 

Louvre Window (Jalousie Window)

Jalousie/ Louvre window- double and triple glazedAlso known as a louvered window, the jalousie window consists of parallel slats of glass or acrylic that open and close like a Venetian blind, usually using a crank or a lever. They are used extensively in tropical architecture. A jalousie door is a door with a jalousie window.

Advantages: Serves certain architectural approaches, good for well ventilated areas

Disadvantages: Thermal, acoustic properties, security of great disadvantage with nearly all systems. Cleaning is often difficult

Skylight (also Roof lantern/ Clerestory)

skylight- double and triple glazedA flat or slope window used for daylight (or moonlight) penetration, built into a roof structure that is usually out of reach. Larger skylights are often multi-panelled, in order to allow for sufficient structural strength to carry their own weight, wind pressure or snow and rain.

Please find all detail in our skylight section (click to follow link)

Advantages: Daylight penetration and vision to the outside (e.g. night sky, landscape).

Roof window

Roof Window- double and triple glazedA sloped window used for daylight penetration, ventilation and view to the outside (or sky). Roof windows are built into the roof structure windows and can be fixed or operable.

Please find all detail in our roof window section (click to follow link)

Advantages: Can enhance ventilation, increase daylight penetration and vision to the outside (e.g. night sky, landscape)

Disadvantages: Depending on type and quality.

Bay/ Bay louvre window

Bay Window - double and triple glazedA multi-panel window, with at least three panels set at different angles to create a protrusion from the wall line.

Advantages FIXED WINDOWS: Great thermal and acoustic properties (Seals well against air exchange between outside and inside of the building); very secure and safe;

Disadvantages FIXED WINDOWS: Ventilation not possible (unless glazing, frame ventilators or other ventilators are used), Cleaning is often complicated and expensive, especially on upper floors

French window (door)

French window - double and triple glazedA French window (French door) is a large door-sized lattice light, typically set in pairs or multiples thereof. Traditionally, they were often used overlook a terrace or garden area.

Advantages: see casement window

Disadvantages: see casement window
