     When studying opportunities to make your home more energy efficient you should never overlook your windows. Gaps and cracking in around window frames accounts for the greatest loss of heat in the winter and air conditioning in the summer. Thankfully, replacement windows are one of the more affordable options to obtaining energy savings for your home. Older, less efficient aluminum or wood framed windows will never provide proper insulation in our extreme climate variations. At Grayslake Window Replacement, we will guide you through the process of not only recouping energy costs but also making your home more appealing.

Should you decide to replace your own windows, please keep the following in mind:

1) The initial measuring of the window space is critical. Making a mistake in this step will affect the entire project. You will want to locate and secure specialized tools and take great care to accurately measure. Our craftsmen are experts in the use of these tools and have the experienced skills to ensure proper measurements.

2) Before replacement windows can be installed, the older windows and frames must be properly and carefully removed. The sliding panels and stationary panels will be removed in this step. There are specific tools that make this job safe and efficient and our highly qualified service representatives are experts in their use.

3) The last step before installation of the replacement windows will require caulking to insure proper insulation. Great care must be taken to apply the correct amount and type of caulking to the sensitive areas. Though this seems like a minor point, it is critical to the integrity of the seal of the windows that the caulking be done properly. Our technicians have the experience and expertise to properly carry this out.

4) Actual installation of the window starts from the inside of the house. The replacement window is put into place and the frame is examined to guarantee a proper fit. Should adjustments be required to provide correct leveling, it is imperative the proper tools are used to do so.

5) Once the window is properly “squared” in the frame, it is fastened into place using metal screws. This is a critical juncture in the installation process because if the screws are misplaced or over-tightened, the frame or glass itself can be damaged. Care is given to properly cover the screw heads with caulking to ensure the window is fully insulated. Again, the expertise required for this point of the installation is not to be taken lightly.

6) Moving to the outside of the home, caulking again is applied to the frame to ensure a proper seal. Additionally, insulation material is applied to the frames themselves.

     Exposure to moisture from the outside elements will be detrimental to not only the replacement window but to the integrity of your outer walls. Great care must be taken to finish the job well.

     At this point, you might be wondering why anyone would consider installing their own replacement windows. We agree.

What exactly are Replacement Windows?

     There is a distinction between the installation of a “New Window” and a “Replacement Window” in order to replace outdated or non-functioning older windows. The greatest differences are:

Replacement Windows are made of what materials?

     Vinyl is the primary material used for replacement windows, along with sealed glass. This formulation is the most effective option available although highly expensive wooden and metal replacement windows do exist.  Vinyl replacement windows are highly effective energy saving treatments and never require painting.

     Generally speaking, there are two styles of replacement windows:

1) The “Z-bar” also known as the “flush fin” covers the space between the interior of the existing frame and the outside of the replacement window. No deconstruction to the outer or inner walls is needed for its use.

2) The “Block Frame” is most often used where wood windows are to be replaced and the outside of the structure is brick, stone or siding. Generally, the wooden frame remains in place but it must be in good condition to do so.

The savings provided as it relates to energy costs will far outpace the cost for installation and since replacement windows are maintenance free, ongoing costs are virtually non-existent.

     The science behind these energy saving windows is extraordinary. The glass panels are specifically designed in such a way as to prevent ultra-violet rays from penetrating their surface while allowing sunlight to flow through unrestricted. They also restrict the amount of heat from sunlight from overwhelming the controlled temperature of the interior of the home. Additionally, in cold weather they prevent heat from escaping to the outside. The result allows both air conditioning and heating systems to retain their temperature controls and reduce the amount of time they require a full electrical load. For the consumer, this translates into dramatically reduced energy bills and lessens the cost of maintenance and replacement of heating and cooling systems.
