WINDOWS

Windows are called the “eyes” of the home. They provide light and views inside the home and help to define the architectural style of a home. Poor quality windows can increase heating bills considerably. Poorly insulated windows allow harmful UV-rays to enter the home and can ruin carpeting and furniture. With all the improvements made in construction technology, many windows now insulate our homes, reducing the amount of heat lost in the winter and making our homes more energy efficient. Energy Star rated windows can save up to 40% on energy usage. They also increase your home’s security, absorb more outside noise to keep your home quieter and more peaceful, and many windows now have lifetime warranties. Replacing old and inefficient windows can be a costly project, but we will work with you to reduce the stress of the process. Here is a short guide describing the different styles of windows that are available

Double-hung Sash Windows – This sash window is the most typical style of window in the US. It consists of 2 window parts, or sashes, that overlap slightly and slide up and down on a track inside the frame. Both parts are usually, but not always, the same size. Most double hung windows use spring balances to support the sashes, but in older homes, you may find weights held in boxes on either side of the window, held up by braided ropes or chains with pulleys.

Single-hung Sash Window – only one sash is moveable – usually the bottom one, and the other is fixed.

Horizontal Sliding Sash Windows – Also called Gliders or Sliders, these windows have one or more sashes that overlap, but these slide horizontally within the frame.

Casement Window – A window with a hinged sash that swings in or out like a door. It can be either side-hung, top-hung or bottom-hung.

Awning Window – An awning window is a casement window that is hung horizontally, hinged on top and it swings either inward or outward . Designed to provide light and ventilation without letting in rain, etc. Found quite often in basements of older homes.

Hopper Window – A bottom-hung casement window that typically opens outward like a drawbridge.

Tilt and Slide Window – a window where the sash tilts inward at the top and slides behind the fixed pane.

Tilt and Turn Window – A window that can either turn inward at the top, or can open inward by a hinge at the side.

Transom Window – A window above a door. If it’s an exterior door, the transom is usually fixed. Interior doors usually have transoms that open by top of bottom hinges, or by hinges at the middle of the sides. They were used to provide ventilation in the days before air conditioning and forced air heating.

Jalousie Window – Also known as a louvered window, this window is comprised of glass slats set in metal clips that flip open and closed like a shutter. Common in tropical areas.

Clerestory Window – a vertical window set high in a wall or roof. Usually grouped in multiples, they let in light without providing a view.

Skylight – A flat or sloped window set high into a roof, that is not easily accessed from the ground.

Roof Window – A sloped window built into the roof, but is easily reachable.

Roof Lantern/Cupola – A multi-paned glass structure that looks like a small building, set on a roof to let in light.

Bay Window – a window with three panels, set at different angles, that protrudes from the exterior wall.

Oriel Window – A many paneled window, most typically seen on Tudor-style homes. They project from the wall, but do not extend to the ground and are held up by brackets and corbels.

Thermal Window – Large semi-circular windows which are usually divided into 3 sections, or “lights” by 2 vertical strips called mullions.

Fixed Window – A window that cannot be opened.

Picture Window – A large fixed window, designed to provide unobstructed views.

Divided-light or Multi-lit Windows – A window with small panes of glass divided by small bars of wood or lead, called muntins. This type of window was most often used until the early 20th century in single and double-hung sash windows, as large panes of glass were not available, and is still a very popular choice today. Nowadays, glazing bars tend to be more decorative, separating windows into smaller panes dictated by the architectural style desired. They are typically made of wood, but occasionally lead will be used for more intricate patterns.

Emergency Exit, or Egress Windows – A window big enough and low enough so that people can escape through the opening in case of an emergency, such as a fire. Many municipalities have specific building codes regarding these windows.

Stained Glass Windows – A window made of colored pieces of glass, held together by lead glazing bars, and usually depicting a scene. Very popular in Victiorian homes and in churches.

Palladian Windows – Large, shaped windows that provide a focal point in a room.

Super Window – A highly insulating window with an extremely low heat loss.

Replacement Window - The term “replacement window” means a window with a nailing fin designed to slip inside an existing window opening from the inside, after the old sashes are removed.

New Construction Window – A window with a nailing fin designed to be inserted through a rough opening from the outside before installing siding and inside mouldings.

Why replace your windows?

Original builder grade windows are cheap and ill-fitting, made from poor-quality materials. They can be hard to open, due to inferior tracks and balance rails. The locks may be misaligned, which can make a home a target for burglars. All of our windows are installed with safety and security in mind.

Studies have found that at on average, at least 20% of heating energy is lost and 40% of cooling demand is gained through windows. Single-paned windows offer no solar heat gain protection. Aluminum clad-windows have no thermal break. When the outside frame gets hot, so does the inside frame.

Frame and Sash Construction - Frames and sashes can be made of the following materials:

*Vinyl and Fiberglass frames have not been around long enough to fully assess their long term durability. Because vinyl is not as strong as other frames, some are reinforced with metal, which reduces the thermal efficiency of a vinyl window frame.

**Modern metal window frames typically consist of two surfaces separated by a thermal break made of an insulating spacer material. While this can double thermal resistance, it is still less than half of that of other frames.

Composites may be used to obtain the looks of one material with the functional benefits of another.

 

Glazing and filling

Windows can be a significant source of heat transfer, therefore, insulated glazing units consist of two or more panes to reduce the heat transfer.

Low-emissivity coated panes reduce heat transfer by radiation, which, depending on which surface is coated, helps prevent heat loss in cold climates or heat gains in warm climates.

High thermal resistance can be obtained by filling the insulated glazing units with a gas like argon or krypton, which reduces conductive heat transfer due to their low thermal conductivity. Window performance depends on good window seals and fastidious frame production to prevent air entry and consequently, loss of efficiency.
