DIY Walls-Only Sunroom Kits

Modular Insulated Walls, Windows & Doors

Enclose Your Existing Porch or Patio Roof

 

Modular Insulated Wall ONLY Kits

This do-it-yourself Modular Walls kit is classified as a “materials supplied” kit.

For homeowners who already have a suitable existing roofline and only need to enclose the space below it, we offer modular insulated sunroom walls that the average homeowner can install. This is a walls-only system, not a complete sunroom roof-and-wall package.

The proudly American-made wall sections are prefabricated and specifically sized for your openings. Using our patented Duralite window technology, the windows arrive preassembled and numbered, ready for installation into the wall panels. The system can turn an existing covered porch or patio into an enclosed 3- or 4-season space, depending on the wall and window configuration selected.

3-4 Season

The original line of insulated walls under systems

Perfect for Moderate to Hot climates

The Alpha Plus™ wall system is constructed with our 3 1/2” thick insulated EPS core material, finished both inside and out with our patented TuffCore vinyl. Generally speaking, it is ideal for 3- to 4-season applications. The wall panels, windows, & doors are all tested and scrutinized by third-party evaluation labs, such as IAPMO, ICC, UL, AAMA, and NFRC, as well as government and state agencies. Our wall system is ideal for adding that additional living space, and using your existing roof line.

4 Season

The ultimate line of insulated walls under systems

Perfect for Moderate to Cold climates

The insulated Omega™ 4″ vinyl ‘thermal clad’ wall system provides the most energy-efficient modular wall system available on the market today. The wall panels, windows, & doors are all tested and scrutinized by third-party evaluation labs, such as IAPMO, ICC, UL, AAMA, and NFRC, as well as government and state agencies. Refined and beautiful, the Omega thermal cladding system conceals all visible screws and caulking. All windows and doors feature high-quality vinyl framing and are NFRC-rated and AAMA-approved.

Step 1

3 Season vs. 4 Season Sunroom Walls

3 Season Walls

We typically will define a 3-season room as one that has single-pane windows and is not going to be heated or cooled on a permanent basis. Both the Alpha Plus and OMEGA systems can be built with single-pane glass windows.

4 Season Walls

We typically define a 4-season room as one that has at least double-pane windows and can be heated or cooled year-round. Both the Alpha Plus and OMEGA systems can be built with double-pane glass windows. Only the OMEGA sunroom system includes the extra vinyl cladding on the extruded aluminum framing to provide an additional layer of thermal protection, making it the ultimate in 4-season comfort.

Your Custom Sunroom Walls Are Designed to Fit Your Space

Please specify the size of your existing spaces that you want to fill, from wall to posts and between existing posts. Any height up to 12 feet is possible. Please let us know what type of door(s) you would like and where you would like them to be placed in each wall. We will then determine the window and module sizes to fit your desired measurements.
