Interior window inserts install inside the building's window opening, leaving existing windows intact, and sealing off a space of 1"-
4" between the old and new windows. This sealed-off air gap provides insulation from heat & cold, as well as sound, lowering your energy bills and reducing outside noises.
There are two parts to the windows—the fixed frame mounted to the window opening, and the removable
window insert pane.
The fixed frame is installed on the inside edge of existing window openings, creating a small 3/4" lip extending toward the center of the window opening.
The removable window insert pane is constructed of high-end, window-grade acrylic glazing with a magnetic frame around it. The
window insert frame adheres to the lip of the fixed frame, sealing the window opening to create the air gap.
The removable window insert panes have small handles so they can be easily removed to open, clean or service the existing window. Once removed, they can be conveniently placed on top of an adjacent
window insert for temporary storage.
We estimate you will save 60% of the energy lost through
your existing windows. The resulting savings on your energy bill can be
significant, particularly if your windows are the most energy
inefficient aspect of your home.
The Department of Energy (DOE) estimates that as much as 30% of
your energy bills are caused by inefficient windows. Typical single paned aluminum windows are very inefficient. Ordinary glass conducts
energy more than four times faster than
acrylic,* and aluminum is actually a conductor of energy!
Interior window inserts are usually much less costly than replacement windows.
The combination of interior window inserts with your existing
windows compares extremely well to double paned, vinyl replacement windows,
according to the Lawrence Berkeley National Laboratories study. In
addition, Sun & Sound window inserts block much more sound than
replacement windows and don't
require removal of your old windows.
Replacement windows typically employ glass for the glazing.
We use acrylic. Window-grade acrylic has four times the thermal
resistance of glass, and has up to 44x greater impact resistance.
First of all, double pane windows are designed for energy
efficiency, not for sound abatement. They are made with two thin panes of
glass, held slightly apart to make a small gap between them.
The small gap is often filled with an inert gas to provide
resistance to energy transfer.
The problem with this design from a soundproof perspective is that
the two panes are too thin, and the gap is too small.
In contrast, soundproof (sound reduction)
windows are designed with as large a gap between panes as is
practical, and at least one pane as
thick as is practical - almost opposite of typical double pane
window design. If your double pane windows let quite a bit of
sound into your home or office, it is really not the window's fault.
Standard double pane windows are NOT designed to be soundproof windows.
Let's compare the STC rating of a single pane window to a double pane window. The single
pane is STC 22-25;
the double pane window is STC 27-32. That's not much of a
difference. Now, compare a single pane window with our soundproof
insert - an STC rating of 40-42.
That's a huge difference. Add our soundproof window to a
double-paned window and get an STC of 45-50!
There are three components that make up the window inserts: The steel
frame, the magnetic channel and optical-grade acrylic.
The steel frame is installed in the window opening. It is painted
with a coating that will not discolor, and is warranted for as long as
you own your home.
The magnetic channel (which holds the window in place) is constructed of a special ABS/PVC alloy
with a UV inhibitor. This alloy has several qualities that make it superior to rigid PVC and other materials: a higher gloss, higher thermal deformation temperature, much greater
durability, and resistance to discoloration. A continuous strip of flexible permanent bar magnet is inserted
into the channel. It is assembled using a patented channel, rather than glues or adhesives
that could fail. This ensures a lifetime of trouble-free operation.
The magnetic channel securely holds a crystal-clear sheet of optical-grade acrylic in place to complete the insulation process, creating the most efficient system available anywhere. We do NOT use Plexiglas™.
It usually takes one day or less for most residential properties.
Commercial buildings vary significantly in size. Small retail strip center suites can be done in one-to-two days.
Office installations vary from one day to a week and hotels can take up to 3 weeks.
In most instances, they are barely noticeable from the inside and can’t be seen from the outside
at all. Our interior window inserts have a very small frame
measuring slightly less than one inch. They come in standard white or
dark bronze, or can be painted to match most window frames or wall colors.
Our windows are warranted for as long as you own your home, and is
transferrable when you sell your home. The materials we use have been
in real life conditions for more than 28 years with excellent results.
Our windows are custom-made on site to fit most shapes and sizes.
Yes. We have two solutions for sliding-glass patio doors, our
standard magnetic windows, or our new laminated glass solution. Our
standard magnetic windows can be removed each time the sliding-glass
patio doors are used, which, if used frequently, can be inconvenient.
However, our new sliding-glass solution with
laminated glass matches the function of your existing
sliding-glass patio doors by allowing you to open them conveniently.
In most cases there is plenty of room to have both the
window inserts and your blinds on the inside of the window frame. If the blinds need to be moved out a little, or repositioned, we usually do that at no cost to you.
Yes. Tinted acrylic is actually a dye placed in the acrylic when it
is being made. Because it is part of the acrylic sheet, it won't peel
or bubble over time. Tinted films should not be
applied directly to acrylic windows due to the unknown nature of the
adhesives and workmanship. Applying tinted films to acrylic windows will void our
We will supply you with enough cleaner to clean about 150 windows. We
can supply you additional cleaner for $5.00 per bottle. You can also use a very mild
dish soap diluted in lukewarm water (3%). Always use a soft cloth like an old T-shirt to wash and dry the windows. NOTE: Do NOT use any cleaners that contain ammonia!
Yes. Sun & Sound Windows come with a warranty for as long as you own
your home, and is transferrable when you sell your home.
There is no limit to the size of multi-paned windows
we can handle. For one-piece 'picture windows' we can go up to
9'X12' in a single piece. If you have a very
large window that you would like to access frequently, we recommend
dividing the acrylic window insert to make it easier to handle.
No. Optical-grade acrylic like we use contains no styrene or other monomers that will deteriorate, causing yellowing and cracking. Through both laboratory and actual outdoor testing, over the last 28 years, 100%
Optical-grade acrylic has been proven not to yellow or crack.
There are several reasons:
1. It’s FOUR times more energy-efficient than glass.
2. It’s lightweight—acrylic is less than half the weight of glass.
3. It’s stronger than glass—acrylic has up to 17x greater impact resistance than ordinary glass of the same thickness.
4. It’s safer than glass— when subjected to a blow beyond its resistance, the hazard of injury is greatly reduced because acrylic breaks into large, relatively dull-edged pieces, which scatter at a low speed.
Our windows provide a maintenance-free, airtight seal year after year. You can count on a lifetime of dependable service from the high quality components used in manufacturing our windows. Cleaning is the only care that is required.
Our soundproof insert (1/4" thick) reduces
sound by 60%-70%. It has an STC rating of 40-42 when installed over a
single pane window. If you have a double pane window, you will achieve an STC of 45-50
with our insert.
Our standard energy efficient insert (1/8" thick) reduces sound by
30%-35% when installed with a single-pane or double-pane window.
Let's compare the STC rating of a single pane window
without a soundproof insert, to a double pane window
without a soundproof insert. A single pane window is STC 22-25;
a double pane window is only STC 27-32. That's not much of a difference.
Sun & Sound Windows are removable. The windowpanes have small handles so they can be easily pulled off of the fixed frame to open/clean/service the existing window.
Our window inserts match the configuration of your existing windows,
single-hung, double-hung, casement, etc., meaning you can remove just
the section that covers the movable part of your existing windows.
Our window inserts are often referred to as interior storm windows because they fit over existing windows like traditional outside storm windows
Traditional exterior storm windows typically have a loose seal and weep holes to keep moisture from
getting trapped between the existing windows and the storm window. This broken seal means very poor insulation. Our windows form a tight seal, creating an insulating barrier between our windows and the existing windows and keep moisture from ever reaching the existing window, reducing or eliminating condensation.
Our system, tested without a prime window, in a simulated 25mph wind,
exceeded the U.S. Department of Energy standards for storm windows by
Traditional exterior storm windows are typically meant to be taken down during the temperate months so that existing windows can be easily opened.
Ours can stay on all year, providing year-round energy savings and
Traditional outside storm windows are typically made to cover the complete window, making them large, heavy and cumbersome.
Our window inserts match the configuration of your existing windows,
single-hung, for example, meaning you can remove just the section that
covers the movable part of your existing windows.
Traditional outside storm windows cannot be removed from inside the house
like interior window inserts. Once removed, traditional outside
storm windows need to be stored somewhere. Our window inserts can be magnetically affixed to the upper/lower pane over the part of your existing window that doesn’t open.
Traditional exterior storm windows are often quite noticeable from
the outside. Our windows are effectively invisible from the outside and almost unnoticeable on the inside.
Built of an ABS/PVC/Ferrous alloy framing with clear, polymer-based acrylic glazing, the windows are 14-44 times as strong as glass, as clear as glass and will not discolor or crack over time. We use optical-grade acrylic, not Plexiglas. And our windows carry a warranty against material failure for as long as you
you your home, which is transferrable when you sell your home.
