and is the only Warranty expressed or implied. The R. Lang
Company (R. Lang), subject to the conditions and limitations
set forth below, warrants its composite vinyl window to be
free from manufacturing defects during the time periods set
forth from the date of purchase.
R. Lang will repair or provide replacement product, at its
election, free of charge, for any window proven to have a
manufacturing defect during the applicable warranty period

of the window required to replace the defective product. R.
Lang shall in no event be liable for labor charges or other
expenses whatsoever in connection with removal or
installation of either the original or replacement product.
However, in lieu of replacement or repair, R. Lang, at its
sole discretion, reserves the right to refund up to the
amount paid by the original purchaser of the window but not
including installation cost. This warranty is intended to
cover individual homeowners and does not apply to products
installed in commercial construction. In the event of repair
or replacement pursuant to terms of this warranty, the

construction and craftsmanship, and with the exception of
components individually outlined within this warranty, for a
period extending 5 years from the date of purchase. This
warranty covers only those manufacturing and material
defects as specified herein and does not include defects or
damages attributable to assembly (when sold as a kit),
installation, normal weathering, or defects caused by
accident, fire, flood, acts of God, vandalism, riot or civil

Glass & Glazing Systems
R. Lang sells its Tru-Frame® Vinyl Greenhouse Window in a
number of configurations, many of which allow its customers
to glaze the window (add glass) using their own materials,
or those they’ve obtained from someone other than R. Lang.
Therefore, the glass warranty below applies only to windows
purchased ASSEMBLED WITH GLASS from R. Lang. Check with the
company the window was purchased from as to who’s glass
warranty your window is covered under. R. Lang
Supplied...The R. Lang installed, sealed insulating glass is
warranted against defects resulting in material obstruction
of vision from film formation, caused by dust or moisture in
the dead air space of the sealed unit for a period of 3
years. If such defects occur, R. Lang will provide a
replacement unit under the outlined terms and conditions
above. Condensation on windows which may occur as the
natural result of humidity within the house or building and
interior/exterior temperature differentials does not
indicate a defect in the window and is not included in the
warranty. Additional information concerning condensation is
available upon request. Not Supplied With Window...R. Lang
assumes no responsibility, implied or otherwise, with sealed
insulating glass units, or any other glass unit, used with
any window unless that sealed insulating glass unit is
supplied by R. Lang. Any warranty communicated to the end
user, with regard to glass not supplied by R. Lang, is the
responsibility of the fabricator of the sealed insulating
glass unit.

not chip, peel, blister, rot or corrode when used in the
manufacturing of windows for a period of 5 years from the
date of purchase. Should any defective material be found
during the warranty period, R. Lang will repaint the
defective material on site free of charge. This warranty
does not cover liability for incidental or consequential
damages for any cause whatsoever. R. Lang does not warrant
against any uniform fading or color change due to normal
weather conditions as normal weathering will cause any
surface to gradually fade or darken.

Expressed Limitations
- Defects or failure caused by improper assembly,
handling, storage, or by installation not in strict
adherence with R. Lang’s written instructions.
- Any damage to the product caused by impact of
foreign objects, acts of God, or by fire, explosion or
other casualty.
- Windows that have been painted, varnished or
similarly coated over the original vinyl surface by
anyone other than R. Lang.
- On some installations caulking is used to seal the
frames or trim package against water or air penetration.
Caulking is not considered a part of the window, and,
therefore, is not covered under this warranty. Caulking
is normally considered a maintenance responsibility of
the homeowner.
- R. Lang reserves the right to discontinue or modify
any of its products, including the color thereof,
without notice, and shall not be liable as a result of
such discontinuance or modification, nor shall R. Lang
be liable in the event replacement material may vary in
color or gloss in comparison to the original product as
a result of normal weathering. If R. Lang replaces any
product under this warranty, it may substitute products
designated by R. Lang to be of comparable quality or
price range in the event the product initially installed
has been discontinued or modified.
This warranty is expressly in lieu of all other oral or
written warranties, liabilities or obligations of R. Lang.
Pertinent state law shall control for what period of time
subsequent to sale a customer may seek a remedy pursuant to
the implied warranty of merchantability or of fitness for a
particular purpose. In no event shall R. Lang be liable for
consequential or incidental damages of any kind, including
any damage to the building, its contents or any person
therein, resulting from the breach of any warranty set forth
herein. No field representative or distributor or dealer of
R. Lang is authorized to make any change or modification to
this warranty. Some states do not allow limitations on or
the exclusion of incidental or consequential damages, so the
above exclusions may not apply to you. This limited warranty
gives you specific legal rights, and you may also have other
rights which vary from state to state.
How To Make A Claim
The property owner must promptly notify in writing the
contractor/builder/dealer who installed the window in order
to provide an opportunity to investigate the claim and
examine the product claimed to be defective. R. Lang and/or
its local fabricator who manufactured the window will be
notified of the claim by copy of the
contractor/builder/dealers report. R. Lang or its local
fabricator will then investigate the claim. If a defect
covered by this warranty is confirmed, R. Lang shall, within
a reasonable amount of time after inspection, either repair
or replace the defective window as outlined in the terms and
conditions above.
Window Maintenance
The factory recommends the use of warm soapy water to clean
all surfaces, including vinyl components. DO NOT USE
Petroleum, Aromatic, Aliphatic, Acetone, or Ammonia based
cleaners or solvents on any surface of the Tru-Frame® Vinyl
Greenhouse Window. The use of these cleaners or solvents on
any surface will void the warranty on the window and
components. As with any window in a residential
installation, all joints and surfaces should be checked at
least once a year for gaps/points where caulking should be
added for the best seal or performance. As mentioned above,
caulking will shrink and move, is not considered a part of
the window, and is not covered in the warranty.
Frequently Asked Questions
1. What is my price for…?
Consult California Energy
Contractors, as the type of installation you chose will
affect your price.
2. Can I get a custom size window?
Special size vinyl
greenhouse windows are available in any size between 2’0 x
2’0 and 6’0 x 5’0. Please contact a dealer in your area for
special limitations and pricing.
3. What are the benefits of Vinyl vs. Aluminum?
Vinyl has, on average,
about 75% less conductivity than Aluminum. This translates
into a better thermal performance, and much greater
condensation resistance. Also, in white or almond, the
finish is never going to rub off. The material is the same
color throughout its structure.
4.
I’m a homeowner, can I purchase direct?
Unfortunately, we are not
structured to sell directly to homeowners. If there are no
dealers in your zip code, pleases e-mail us and we will
happily help locate a dealer near you.
5.
Can we get sculptured grids?
Sculptured grids are not
available. We do offer a flat 5/8” grid (marginal pattern
and most special grid patterns can be accommodated).
6. What colors are available?
White interior is standard with White
exterior windows.
Almond interior (with a black bottom board) is standard with
Almond exterior.
Special exterior color windows are manufactured with White
interior (limited color selection, ask your dealer for chart
of colors available).
7. What is the window projection?
The inside projection is
16” and the outside projection is 17 3/16”.
8. Can we tile into the window?
Our 4’0 X 3’9 unit is
designed for most kitchen counter applications. The bottom
board will easily hold 25 lb per square foot. The thickness
from the bottom board to the operating vent is 1 ¾” but we
recommend a maximum accommodation of 1”- 1 ¼”. Exterior
support brackets are recommended when tiling into the
window.
