Doors and superior-quality windows
A sound Choice!


D & P Marchand is at the service of its customers to meet their needs. We have chosen to distribute FENPLAST products: casement windows, sliding sash made of PVC with a glossy high quality finish.

These windows will meet the most demanding needs, both for renovation as well as new construction projects.

Hybrid casement or awning window ECOPLUS

Fenplast has ventured into the area of hybrid windows with a typical casement model called EcoPlus. This very window can also be used with the awning opening system. 

The EcoPlus window is a structural casement window with three levels of weather-stripping. The frame and sash are made of very strong multi-chamber PVC, and all corners are soldered at 45 degree, providing incomparable efficiency and rigidity. Aluminium extrusions are inserted into the PVC part in the exterior, providing remarkable structural strength.


PVC casement or awning window ISOPLUS

This window, which is an innovation in the market of PVC windows, is noted for its structural-type frame, which gives it a contemporary aspect while reducing the thickness of the center “post”. This window system was designed to offer you “Plus”: an elegantly profiled sash, which is gracefully rounded, as well as a window frame with integrated moldings to meet your needs. Three weather strips (two on the sash and one on the frame) ensure waterproof of the window, thereby guaranteeing optimum performance. It can also accommodate a triple glazed sealed unit for better energy performance.


One of the most overlooked alternatives for small openings is the awning window. This type of window has the same safety and performance features as the casement window. The “scissors” type mechanism in the lower part of the window allows for indirect ventilation.

This type of window may also be installed over each other to give it the warm aspect of a hung window, while maintaining the advantages of a “compression” closure.

Horizontal sliding ISOVISION

This type of well-known window stands out for its simple operation. Because of its design, the sashes are narrower, which increases luminosity and they do not stick outwards when opened. It offers excellent ventilation and its maintenance is greatly simplified by tilting the sash(es) towards the inside. This window is an ideal solution on a strict budget or as a basement window.


Both sashes are movable to supply ventilation on the right or the left sides. Both sashes tilt inward, which allows handling them easily for cleaning purposes without having to withdraw them from the frame. This system ensures a maximum unobstructed opening for carrying material in and out. This window may be ordered with a full mosquito screen, thereby determining which side is to be opened, or with a half mosquito screen for greater luminosity.



With only one movable sash, this economical window is a wonder of simplicity and clean design. The sealed unit is held in place not within a sash but by the frame of the window itself, as well as by the mullion. You can specify the operating side as required. The mullion is a refined design which gives the whole window the appearance of a casement window. The ease of operation and ruggedness of this window make it a most sought after choice.


Vertical sliding window ISOVENT

This traditional English-style window features easy maintenance and a large glass surface. Available with all types of glass, panes, and fake mullions typical of Fenplast windows, this window, which is adapted to modern technology, is sure to please the most discerning buyer. 


This window, with two movable sashes, ensures excellent ventilation. The exceptional results obtained in the various waterproofing tests is a distinct advantage of this window. You may choose from a full size mosquito screen (as shown) or a half size mosquito screen.


Still the same type of window but built so that only the bottom part of the sash is movable. This window, which is more economical with no compromise in performance, surprises by its integrated aspect. The horizontal mullion, which is simple and straightforward, is mechanically assembled to ensure structural rigidity.

Panoramic frame ISOPANO

The IsoPano© window is a panoramic type frame with a width of 4 1/2'' and is used in applications requiring a fixed window.

Irregular Shapes ISOGÉO

Over time, Fenplast has acquired the experience necessary to offer you windows with various geometrical shapes, thereby meeting your architectural needs and allowing you to personalize your home as you wish. The shapes shown on this page are only a few examples of the numerous possibilities offered.

Bay and bow windows

What's better than a bay window (3 sections) or a bow window (4 or more sections) to make your house stand out? This window features various possibilities of inside finishing, either in oak, pine or laminated material, thereby dramatically enhancing the esthetics of this type of opening.

These windows may also be manufactured with angles made to meet your requirements, thereby ensuring a perfect finish, especially for your renovation needs. These bow windows will ensure outstanding luminosity and will be an ideal location for growing your plants and flowers.


True divided lite

One of the “esthetic” options that is very popular is the True Divided Lite, a 2'' mullion that divides the sash (vertically or horizontally) into two or three sections. This mechanical division, with each sections built with an independent sealed unit, allows for the easy replacement of the sealed units, if ever needed. (Available only in the IsoPlus© and IsoPano© series).

Fake mullion

Another way of giving a distinctive look to a door or a window is to add fake mullions (SDL) on the glass surface. These fake mullions measuring 13/16'' (34), 1 1/8'' (118) or 1 5/8'' (158) in width are glued directly on the sealed unit with a tape that is especially developed for this application. These fake mullions may be applied only on the outside glass surface or on both sides of the unit. The addition of an integrated muntin bar that is aligned with the mullion greatly improves the esthetic aspect of the windows and doors set.


An economical but nevertheless very esthetic way of personalizing a home is to add grilles to the windows and doors. The muntin bars are inserted between two sheets of glass, thereby avoiding tedious maintenance without voiding the warranty of the sealed units.

Jamb extensions

Three finishes are available: PVC-cladded pine, select pine or oak-plated. These wooden jamb extensions may be inserted in the slot [insertion option] or directly screwed on the window frame [screw option] for greater structural strength.

Casing & rosettes

It is possible to add in our doors and windows, a full PVC casing. Rosettes held in place with a screw hidden in its center complete the installation. This esthetic addition completes any installation in a jiffy and eliminates painting. Even more, the system is designed to be removable if you decide to paint the wall in a few years.


The PVC extrusions used in the manufacturing of Fenplast windows are made out of white resin and the standard steel door panels used are all white pre-painted.

However, because this does not necessarily meet all tastes or styles, Fenplast offers the possibility of having the outside sections of the windows and the outside or/and inside of the steel doors painted in its workshops with a choice of more than 20 standard colors or with the specific color you would like to have.

The paint used for this application is especially formulated to prevent the heat absorbed by it from being transferred to the material behind. In doing so, the materials maintain their dilation/contraction properties almost intact, thereby allowing them to be painted from pale to darker colors. Therefore, you may let your imagination soar and choose your favorite colors to harmonize the colors of your doors and windows to that of your home.
