One of the most common renovations preformed in a residence is tackling the out-dated bathroom. Weather you’ve hired a pro contractor to build your dream bathroom, or your a Do It Yourself aficionado replacing the vanity, tile, and other things by yourself… let Exeterglass help you achieve your glass needs. The bathroom mirror is one of the best places to achieve a more modern look. A great idea that makes the room feel bigger and reflects more light into the space is to oversize your mirror and mount your light fixture through the mirror. Case in point with the attached picture in this post, the client wanted to re-do the window trim to encompass the vanity mirror provided by Exeter Glass. We precision field measured, cut the light fixture holes in our glass shop, delivered and installed the mirror for the client. The look provides a more custom feel in the bathroom renovation, while also reflecting more natural and artificial light around the space to make it brighter in the morning or night.

Windows provide daylight, ventilation, and solar heating to the inside of our homes, but they are also potential sources of energy loss that can lead to excessive air conditioning and heating costs. The National Association of Home Builders Research Center estimates that 43 percent of American homes have single-pane windows that would benefit from cost-effective improvements. Fortunately, advances in window technology offer far more solutions to energy loss than ever before. As evidence of the choices in window technologies available to satisfy a range of climate demands, we need only note the 34 different generic window types — various glazing materials and designs combined with four frame types — that have been tested by the Center for Sustainable Building Research at the University of Minnesota in each of the four ENERGY STAR® climate zones.1 Researchers evaluated window performance in these tests based on annual energy costs, peak demand, winter and summer thermal comfort, and condensation resistance.

The U.S. Department of Energy (DOE) advises consumers that the best way to improve a home’s energy efficiency is with new, energy-efficient windows, but if one is on a tight budget, storm windows are a less expensive option.2 Storm windows are typically mounted on the inside or outside of single-pane windows to improve thermal efficiency. One benefit of a storm window is the creation of dead air space between it and the prime window, which reduces the heat conduction that normally leads to heat loss in winter and to solar heat gain in the summer. A second advantage is a decrease in the air infiltration, or leakage, common to older windows. For these reasons, DOE states that homeowners can reduce heat loss by 25 to 50 percent by installing interior or exterior storm windows.3

In 2002, the Lawrence Berkeley National Laboratory compared the efficiency of different prime/storm window combinations with that of a replacement window treated with a low-emissivity (low-E) coating of metal or metallic oxide to reduce heat loss or gain. This transparent coating not only reduces heat emissivity but also blocks out the ultraviolet light that fades and damages home furnishings. Under simulated conditions, net heat flow comparisons were made based on various prime/storm combinations (prime alone, prime/low-E external storm, prime/ low-E internal storm, prime/regular external storm) with the low-E replacement window. The research team found that the “addition of low-E storm windows to the prime window provided performance very similar to that of the replacement window, and expected differences in performance were only detectable through a sensitive fitting procedure (essentially, a long-term averaging)” (p.14).4

In 2006, HUD’s Partnership for Advancing Technology in Housing (PATH), the National Association of Home Builders Research Center, and DOE completed a field investigation under actual conditions.5 This study focused on the difference that low-E storm windows made in reducing residential heating requirements for six Chicago homes that were eligible for the city’s low-income weatherization program. These single-family detached homes featured the original single-pane windows typical of construction from the 1920s through the 1960s. The bungalow style homes had brick facades over concrete block exterior walls and no insulation in the walls.

Over the period of one heating season, researchers monitored each home under two conditions — without storm windows and with new storm windows fitted with screens to provide ventilation in spring and summer. Four of the homes with storm window retrofits used windows with a low-E coating, and the other two were fitted with clear glass storm windows. Occupants maintained the same thermostat settings and heating patterns throughout the test, allowing energy use comparisons before and after the storm window installation.

After researchers installed the storm windows, air infiltration measures declined by an average of 15 cubic feet/minute per window. Glass surface temperatures varied significantly between the clear and low-E storm fitted windows. The U-factors, or measures of thermal transmittance, for the single-panel/clear storm window combinations were 0.49 and 0.42, whereas the single-pane/low-E storm combinations had U-factors ranging from 0.36 to 0.30. To put this in context, a lower U-factor means greater efficiency; the prescribed standard for the Northern ENERGY STAR climate zone, in which Chicago is located, is a U-factor of less than or equal to 0.35.6 In terms of tangible outcomes, reductions were realized in air infiltration, energy usage, and expenditure, as shown below for four of the homes.7

Overall, energy use declined by 13 percent in the homes with clear glass storm windows and by 21 percent in those retrofitted with low-E storm windows. The cost per window was estimated at $45. Installed costs for the clear storm windows in Houses 3 and 4 ranged from $1,344 to $2,661; for the two houses installed with low-E storm windows, the cost was $1,738. The average time for Houses 3 and 4 to recoup the costs was projected at 10 years, whereas the projected payback period for Houses 2 and 5 was less than 5 years.

House Storm Window Leakage Reduction Energy Savings Annual Savings
2 low-e 6.3% 19% $490
3 clear 8.2% 8% $111
4 clear 6.8% 18% $317
5 low-e 6.4% 23% $341
Although the referenced studies were small, they demonstrate that storm windows can offer a cost-saving alternative to new windows.

With the beautiful weather we have been receiving in New England this year, your probably thinking about spring a little earlier than usual…. and not to far from that are thoughts of Spring cleaning. Here at Exeter Glass, we asked some of our glass experts to share some of their favorite glass cleaning tips, and compiled them in the list below.


  • Wash one side of a window with horizontal strokes and the other side with vertical strokes. Then you can pinpoint which side of the window has the streaks.
  • Use a squeegee on a long handle or sponge/squeegee combination to prevent streaks on large windows.
  • Eliminate tiny scratches on glass by polishing the affected areas with toothpaste.
  • Washing windows should be done on a cloudy day, because direct sunlight dries cleaning solutions before you can polish the glass properly.
  • Use a soft toothbrush or cotton swab to clean corners.
  • To give an extra shine to window glass, polish it with well-washed cotton T-shirts or old cloth diapers.
  • Polish windows to a sparkling shine with a crumpled newspaper. The paper also leaves a film that’s resistant to dirt.
  • Wash windows from the top down to prevent drips.

Happy Spring!

Modern shower designs have evolved through time and the traditional frame less shower doors and tacky shower curtains have been replaced by the up to date, elegant and chic shower doors of today.

Since most contemporary style bathrooms are usually visual and feature intricate bathroom fixtures and decorative tiles, frame less shower glass doors have been gaining fame among many homeowners.

Exeter Glass frame less shower doors are a type of shower door made with solid portions of glass with no trims supported by heavy-duty hinges for pivot type, and tracks for bypass/sliding type.

Selecting frame less or framed shower doors will depend on personal choice and budget. To help you decide, below are the pros and cons of purchasing and owning the modern frame less shower bath doors.

Made entirely of glass, they can easily make your bathroom look fresh and elegant. Its invisible appearance creates flowing space and a sweeping look that matches stylish bathroom designs, making the space seem much bigger and grander than it may be otherwise. Decorative tile designs and ornate lightings in the interior of the shower area are put on display as well.

Durability is reliable because thicker glass is used for it to support the panels that do not have the structural edge of aluminum framing. This kind of shower doors is easier to clean and can be restored to looking like new, due to the trackless design. Plus, the seal-in technology of frame less glass doors keeps the water from spilling out to the greater bathroom area.

Homeowners are usually concerned about the safety of frame less shower bath doors due to absence of a protective trim that runs alongside the glass. However, our trained professionals have been assisting costumers pick our and design the right frame less application for their unique situation. Our glass is thick (weighing over 70lbs in some cases) and designed to support its own weight in lieu of a frame to support it. However, because of the size and other factors in a frame-less door application, it can be up to forty percent more than the regular framed door… so caution must be taken particularly during the installation process to not chip or damage the glass during the install.

Despite these minor cons and mus-conceptions though, frame less shower doors are wonderful to have if you can afford to increase your project budget to splurge on some luxury for your bathroom. The end result will not only exemplify your design, but also add resale value to your home.

Below is a video we found on youtube that we thought was interesting enough to share. It shows the process of how glass was made in the 1930’s. This video is pretty unique and rare find for its time showing the entire industrial process. It is quite an interesting video if your are interested… click play below.
