Benefits of proper Installation and High-Performance Windows and Doors


Windows and  Doors

Windows and Doors  are  for natural lighting and ventilation ,as emergency exits, and as an integral component of the architectural style of the home. When it come time for major renovations  around the home, attention  to energy  efficiency and  economic  as they  are to  architecture and  aesthetics.
Typical windows will last  up to  twenty years  or more. Therefore , the decisions  costumer  make in the selection  of  windows and doors- either  for renovation or a new home - can help define energy efficiency  and comfort levels in the home for years to come .

High- performance windows and doors  offer significant improvements in solar control, thermal comfort
and  energy efficiency. They do this by incorporating low-E coatings, inert gas fills, and better edge spacers and frames. Noble Windows & Doors explains how these  advances in windows and doors technology work, and will help you make informed decisions about purchasing windows from Noble Windows & Doors .Whether you are replacing units in an existing home or designing a new home.

With windows improvements, you have determine what is wrong with existing units what your expectations are in upgrading, and how much you want to spend. In some cases , new windows will be required.  Many frames are so inefficient, you may wish to replace them.

The sun’s energy is free .Solar energy  can improve the lighting and comfort of your home and it can cut your fuel bills. Decisions you make at the planning stage about the number of windows ,their size and location, will be as important a consideration in determining your window requirements as their isolative properties or how they look. Over past several years the rules for windows placement have changed with advances in window technology .The  arrival of high-performance windows has given costumer more choice in window selection.
Door also play an important part in the energy performance of the home especially if you have a lot of patio doors.Depending on the condition of existing door energy-efficient replacement units may contribute to increased comfort and reduced energy bills. An added bonus of energy-efficient doors is that they tend to be heavier and more robust than conventional doors , thus enhancing the security of  the home.


What to look for in Windows and Doors

The wide variety  of windows and  doors  available on the market can make the task of selecting appropriate units confusing. Price may not always  be the determining factor. The cheapest units you can find may not perform at the level you want. The cost of energy-efficient, high-performance windows can be 10 to 15 percent  more than the standard double-glazed unit. However, many window manufacturers are switching over their entire production line to produce only high performance units so , in effect ,there is no price differential as far as they  are concerned. Today ,the high-performance windows  is  becoming the industry  standard.  But it can still be confusing. For example , some windows manufacturers include  low-E coatings  in their  standard windows , with gas  fills as an upgrade ,at higher cost, while  others offer gas fills and special  coatings as an upgrade. The key is to select windows or doors that are as energy-efficient as possible , given your  needs and budget. Remember that some super high-performance windows may cost considerably  more then normal high-performance windows. The energy rating [ER] ,will give you an indication of the energy benefits. More efficient unit  will probably offer other  advantages , such as better

Comfort and resistance to condensation in  very cold climates.

Window and  Door Types

There are two types of windows; those that open and those that don’t - called operable and fixed.
Fixed windows are more efficient because  of their better air tightness characteristics. They also offer the most safety and security. Of the operable units, there are many forms; awning casement, hopper, horizontal slider, vertical slider [either single -or double-hung] and turn-and tilt

There are two ways of sealing operable windows to minimize air leakage; with a compression or a sliding seal . Windows with compression seal are generally the more airtight of operable types and should be the window of choice whenever possible. Casement , awning, hopper and turn-and tilt windows, for example should have a  closure/locking  mechanism that pulls the unit tight  against the seal.

Doors are a little less complicated. They are either ; solid ,solid with an insulated core, solid with window, or solid with an insulated core  and windows. Patio doors operate like a large horizontal sliding window.
Some materials reduce heat flow better than others .Solid wood door, for example. are not as good as metal-clad, Insulated core door, depending on the style of door and insulation  material used to fill it.

Glazing  Types

When we  speak of windows ,we tend to use the terms single-,double- or triple-glazed. These  terms simply refer to the number of panes of glass incorporated into the window unit; single-glazed- one pane ;double - glazed-to panes; triple -glazed -three panes. All windows in Canada should be at least  double - glazed.
Most windows manufacturers offer several types of glazing , which affect the insulation value  of the windows and the  likelihood of condensation forming on the glass .Sometimes , transparent plastic films are placed inside the glazing unit between the panes of glass to increase energy efficiency.
A variety of coatings on the glazing surfaces- plastic films or inert gases between  glazing , for example-can increase the insulating value of a double -glazed window to more than equal that of a standard triple-glazed window. Coating are often used  with gas fill.

Spacers

If you  look between the  window panes in a conventional double- glazed window where the glass meets the frame , you will probably see a strip of material , known as a spacer. The purpose of spacers is to maintain a uniform separation between the panes of glass . Metal spacers  conduct energy easily and are a significant source of loss and poor windows performance .The best insulating  spacer are often made from non -metallic materials.

Frames  and  Sashes

A window consists of a glazed unit a frame and a sash. The glazed unit fits into the sash, and the frame holds the sash. The frame and sash may occupy as much as one third of the total window area. Highly conductive  materials used in the construction of the frame and sash must have thermal breaks incorporated
in order to reduce heat loss. Frames and sashes are manufactured from a variety of materials -  aluminum ,fibreglass ,vinyl , wood , and combinations of these materials .Each material has benefits and drawbacks in terms of insulating value , strength ,durability, cost , aesthetics and   maintenance requirements. Good quality windows can be made using any of these materials. Use the Energy Rating to compare energy performance
