Grand Vista 3 Season Sunrooms

Escape to your private oasis and enjoy your backyard like never before with our completely pre-fabricated sunroom wall and roof systems.


A Sunroom Wall System Designed From The Ground Up

We designed Grand Vista from scratch in the early nineties, and it has performed fantastically ever since. Grand Vista three-season sunrooms are comprised of custom-made wall sections typically not exceeding five feet in width. Options include swing doors,  patio doors, tempered glass kneewall, fixed glass transoms above the windows and more.

Each wall section of your Grand Vista sunroom comes standard with an operating window, including screens (no “filler” panels like other systems). So, on those warm sunny days, you can open each of them to enjoy the warm breeze and smell the flowers. Fixed glass wall sections are also an option.

For the roof of your sunroom, choose from Craft-Bilt’s Northlander Skyview translucent roof system or our PanelCraft™ aluminum insulated roof panels. If your new patio room doesn’t fill the whole deck, you can extend the roof to one side to create a rain-free patio cover area for barbecuing, playing, or just sitting outside and enjoying nature.

Sunroom Inside View

Exclusive Sunroom Wall Design

Grand Vista Three Season Sunrooms with side sliding glass windows feature our exclusive wall design optimized for appearance. Look closely; there are no window frames cluttering the look of your sunroom; they’re built right into the wall! None of that “storm window” look.

Side sliding windows are preferred to double-hung windows; they make your sunroom look better and provide the best view. The nylon rollers in our sunroom windows will provide a smooth opening & closing operation for years.

3 Season Sunroom

Grand Vista 3-season sunrooms are available in white, sand and earthstone. Refer to our 3-season sunroom specifications section for colour chips. They feature a maintenance-free aluminum wall approximately two inches thick.

Most of our sunrooms are installed on homes, but Grand Vista sunrooms have also been installed on cottages and park model trailers.

At Craft-Bilt, we understand the importance of creating spaces that reflect your lifestyle. Enclosing your porch with our 3-season Grand Vista walls adds value to your home and creates a cozy retreat for relaxation and entertaining.

Grand Vista 3 Season Sunroom Features

Adjustable Pitch for Roof:
Grand Vista sunrooms feature our unique swivel header design. Compared to the industry standard of a simple square channel sitting atop of your walls, our Grand Vista header means:

  • The inside of your sunroom has a clean curved look. (The industry standard of square channel results in an unsightly gap)
  • The roof panels are properly supported no matter what the pitch. (The industry standard has all the weight of the panels and snow bearing on the outside edge of a square channel
  • Our Swivel Header results in a “double hollow” effect. Two hollow chambers provide great rigidity so that even when your roof is loaded with snow, the windows will operate properly.
  • Full glass views (floor to ceiling glass walls) available in all styles.




Water Control System:
The Floor Channel of your Grand Vista sunroom is designed with a slope so that moisture runs to the outside. Attractive weep hole covers exceed the industry standard of simple site-drilled or site-punched weep holes.




Window RollersEasy to Operate:
The Grand Vista windows glide on nylon rollers. Other windows in the industry use plastic blocks.





Weather Control / Strength

  • Look closely, the weatherstripping is “cradled” in concave shaped guides, resulting in a better seal and smoother operation.
  • Note the hollow chamber. “Hollows” cost more to produce, but provide superior strength. Grand Vista Header & Sill extrusions are both “hollows”. The industry standard is a less expensive non-hollow shape.
  • The sloped Sill of the Grand Vista sunroom window means your room is dry and there is no standing water in the tracks.
  • The screw ports that hold the Grand Vista walls sections together were designed for #10 gauge fasteners. This provides greater strength compared to the industry standard of #8 gauge.



  • Attractive weep hole covers





Available Colours in Three Season:

White, Sand and EarthStone

4 Track Window Colours


Frequently Asked Questions for Sunrooms:

What is a sunroom?

A sunroom is a pre-fabricated wall and roof system added to your home to provide added enjoyment of the outdoors and extra living space. They are made of maintenance-free materials, predominantly aluminum but also vinyl and fiberglass. The wall sections are typically custom made, no greater than five feet in width. Each section contains a side sliding window, beneath the window is the “kneewall” which is built with a solid panel or tempered glass. If extra height is desired, “transom glass” is added to the tops of the windows and doors.

There are two basic sunroom shapes: studio sunroom (also referred to as lean-to sunroom or shed roof sunroom) and A-frame sunroom (also referred to as cathedral sunroom, peaked roof sunroom or gable sunroom)

Sunrooms come in two types: three season (single glazed windows) and all-season (insulated wall and windows). All-season sunrooms are also referred to as four-season sunrooms or insulated sunrooms. Typically the roof is made with insulated aluminum panels that come in varying thickness. Thicker panels have more insulation and can span farther.

Sunrooms have typically differed from solariums because they don’t use glass in the roof. This line has blurred in recent years with the introduction of polycarbonate roof systems for sunrooms. Solarium walls typically have a great deal of fixed glass with the occasional casement window while sunroom walls will typically consist of corner-to-corner side sliding windows.

What is the best way to utilize a sunroom?

Sunrooms are used for many great reasons: entertainment, place to relax, room for my pets, TV room, enjoy the outdoors and seasons… the list goes on and on. Finishing touches like beautiful flooring and wicker furniture help create that perfect retreat.

What are the advantages of Craft-Bilt’s sunrooms vs. competitors?

There are many technical advantages to Craft-Bilt products like thicker wall extrusions with intelligent designs. All of our sunrooms utilize swivel header designs that support the roofs weight evenly and eliminate unsightly gaps inside the room that competitors don’t address or cover with an ugly angle. Weatherstripping is important to keep out the wind and bugs, that is why Grand Vista three season window frames use ingenious concave tracks to cradle the weatherstripping providing an excellent seal. There are many other unique features to our rooms that you can find on the Specifications tab or let us refer you to a local contractor who can describe them to you.

How much does a three-season patio room addition cost?

There are a lot of variables: Is a new deck required? New footers? Is there an obstruction, an exhaust fan or a water spigot that needs to be moved? An installed 12 x 12 three-season sunroom will start around $25,000, not including the deck, building permit application/drawings and other factors.

What is the return on my sunroom investment?

There have been many studies and opinions published in renovation magazines about the value of major renovations like kitchens, bathrooms, and sunrooms. Check out resources like Remodeller magazine and search for their Cost vs. Value report. Sunrooms are often in the top ten for return on investment, recouping at least 50% of your investment. There are factors that can affect your return on investment, like where you live.

But the real return on investment is the improvement in your lifestyle. Your sunroom will quickly become the favourite room in the house, your very own private retreat. You can’t put a price on peace and tranquility.

How long does it take to install a custom sunroom?

The actual installation can take as little as two days for a three season patio room. Additional time will be required if you are building an A-frame style sunroom, a new deck is required, a service (i.e. gas meter, water spigot, bathroom fan, etc.) needs to be moved, or there is some other complexity to the project.

Often there can be delays obtaining the building permit or zoning approval. Your contractor will not order material until the permit is issued after which you have to contend with the backlog at the factory. Although your contractor will schedule the work when the sunroom is ordered, his backlog may be even longer than the factory!

Altogether, from the signing of the contract to the finished sunroom, eight weeks may have easily passed. So if you are planning to build a sunroom and hope to enjoy it for the summer, get started early!

Can I use my existing deck for my sunroom?

If your deck was built to building code specifications, there is a good chance it will suffice. Open decks are built with a slope away from the building, so even if it is code compliant it will need to be leveled. Deck blocks will not do. Your deck needs footings, typically concrete piers deep enough into the ground to not be lifted when the ground freezes. In southern Ontario, that is usually four feet, in colder climates, it will be deeper. Imagine the damage to the sunroom or even your house when an un-footed deck heaves upwards in freezing temperatures.

In recent years helical piers have been used by many sunroom contractors instead of concrete footing. These are essentially steel augers that are drilled into the ground and left in place to support your deck. Talk with your contractor about the benefits of this footing option.

Do I need a building permit for my sunroom?

Yes. Often your contractor will include the drawings and filing for the permit as part of their price to you. Contractors do not get enough credit for the time and effort it can take in getting a permit.

Can I install it myself or do I need a contractor?
