Finally, for those of you who want to create a four season space with your existing roof line, we offer a modular insulated walls only system that the average homeowner can do. All your sunroom walls come prefabricated in sections, specifically sized for your openings. Using our patented Duralite window technology, all windows are preassembled and numbered, ready to be installed in the wall panel. Perfect for summer season bug protection and ideal for keeping winter cold at bay. This affordable 3 & 4 season sunroom 'walls only' system can be used to transform almost any existing patio or porch roof into a patio enclosure get-a-way that can be bragged about for decades to come. We provide all the modular walls, additional aluminum profiles, hardware, sealant and directions - - everything internal to the installation. You provide the tools and labour.

You get the highest quality, durable, maintenance free materials - - all at a price that will not break the bank, and it comes with all the help you need from Home Porch & Patio Kits Inc.

Understanding Our Terminology

3 Season Walls

We typically will define a 3 season room as one that will have 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 will define a 4 season room as one that will have at least double pane windows and could be cooled on a permanent basis. Both the Alpha Plus and OMEGA systems can be built with double pane glass windows. ONLY THE OMEGA sunroom system comes with the extra vinyl cladding on the extruded aluminum framing to provide that extra layer of thermal protection making it the ultimate in 4 season comfort.





These are not 'cookie cutter' modules!

Therefore you will not find fancy click and design software, that never understands what you actually want, on our WEB site.


Your desired size is what we work with

Simply tell us 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. You tell us what kind of door(s) you want and where in each wall they are to be placed. We will then come up with window and module sizes to the fit the measurements you want.
