How Can You Enclose A Porch With Plexiglass?

One of the primary functions of porches is to protect you from the elements when entering your home. In fact, the word ‘porch’ is derived from ‘portico’ and refers to a building appendage supported by columns. The roof of a porch allows it to protect you – but in the winter, that may not be enough!

To increase the effectiveness of your porch, you can enclose it. The national average for basic porch enclosures is around $1200, while the national average for high-end enclosures is around $13,000. Naturally, it can cost even more than this to enclose your porch – but it can also be a lot more affordable!  

Plexiglass is a fantastic alternative to enclose your porch, especially during the colder months. Using plexiglass is an inexpensive and simple way to enclose your porch. Not only will this help during the winter by sheltering you from the elements, but it can keep bugs away and increase your porch’s privacy. During the hotter months, plexiglass sheets are easy to take down.

Plexiglass can fit into the existing spaces of your porch by attaching them directly to your porch structure using nails. While you’ll need to measure the dimensions of your porch, this process is compatible with most roofed porches. If you want to attach plexiglass sheets between your porch’s existing vertical beams, you can follow the steps outlined in the following section.

Enclose A Porch With Plexiglass In 6 Steps

To enclose your porch using plexiglass sheets, you can follow these six simple steps!

Step One: Gather Your Supplies

To enclose your porch with plexiglass, you’ll need the following DIY supplies:

  • Measuring tape
  • Drill and drill bit
  • Hammer and nail
  • Plexiglass sheets
    • Clear and frosted plexiglass sheets are available in many sizes to accommodate your porch’s screen section dimensions.
  • Tool to cut plexiglass sheets (if necessary)

Step Two: Measure Your Porch’s Screen Sections

Before you enclose your porch, you’ll need to measure the width and height of each screen section. As you measure these sections, make sure to write the measurements down. To ensure your plexiglass sheets are large enough to cover each section, you should add 4-inches to the height and width of each measurement.

Step Three: Prepare Your Plexiglass Sheets

Since plexiglass sheets are available to purchase in many different sizes and thicknesses, you should be able to find the right size plexiglass sheets to cover your porch’s screen sections. If your plexiglass sheets are too large, there are many tools that can be used to cut them to the appropriate sizes.

Step Four: Drill Clearance Holes In The Plexiglass Sheets

To ensure your nails don’t crack your plexiglass sheets, you should drill clearance holes in the sheets. The drill bit you use should be the same diameter as the nail you plan on using to attach the plexiglass to your porch structure. You should drill clearance holes in all the corners of your plexiglass sheets.

Step Five: Nail The Top Of The Plexiglass To Your Porch

You may need someone to help hold the plexiglass sheets in place while you hammer the nails into the top clearance holes. Once you’ve hammered a nail by the top right clearance hole, you can nail the top left side.

Step Six: Nail The Bottom Section Of The Plexiglass

Once you’ve nailed the top section of a plexiglass sheet to your porch’s structure, you’ll need to hammer the bottom section of the sheets. Once the four corners have been nailed, the plexiglass sheet will be fixed to that section of your porch. You’ll need to repeat Step Five and Step Six for each screen section until your porch is fully enclosed.
