Foam weather stripping vs vinyl: Which is the better choice?

Weather stripping helps prevent drafts from entering through the gaps around doors and windows, keeping indoors at a comfortable temperature. 

There are many types of materials to use for weather stripping, including classic foam tapes and vinyl strips. Know which material is best for your sealing needs in this foam weather stripping vs vinyl guide. 

What is foam weather stripping? 

Foam weather stripping involves using foam tape to seal gaps around doors and windows. It conforms to irregular gaps and spaces because the foam material can return to its original shape and size after being compressed.  

You can find many types of foam weather-stripping materials, including:

• Open-cell foam tape - has a porous texture with good sound-proofing capabilities. It’s made of various materials such as felt and Polyurethane (PU). 

• Closed-cell foam tape - it’s denser and tougher, providing better protection against water and moisture. Some materials include neoprene, Ethylene Propylene Diene Monomer (EPDM) rubber, and Polyvinyl Chloride (PVC).

What is vinyl weather stripping? 

Vinyl weather stripping involves using rolled vinyl, V-strips, and reinforced strips to provide a permanent rigid sealing solution. It’s known for its strength and durability, so it’s suitable for sealing areas that must withstand heavy use or exposure, such as exterior door seals. 

Vinyl vs foam weather stripping: What is the better material for weather stripping?

It’s best to seek professional weather stripping services for proper application installation. However, it pays to know more about it. After all, the decision is still yours on which weather stripping you should use for your home.

In terms of weather protection

Vinyl weatherstripping provides excellent weather protection since vinyl has good moisture resistance, helping prevent condensation puddles in windows. Some vinyl weather strips for windows and doors even have UV-resistance properties. 

On the other hand, foam degrades faster over time, so it doesn’t offer much protection against harsh weather conditions. But, if you only need a quick fix to improve insulation, foam weather stripping is a good choice as it can seal irregular gaps, helping absorb shocks and vibrations. You’ll find foam window seals especially useful in blocking the sound of thunder during heavy rainfalls.

In terms of insulation 

You can use Polyurethane (PU) foam tape and window condensation strips to block draught and improve insulation. PU foam has a porous structure that can trap air and reduce heat transfer, helping prevent your air conditioning system from working too hard.

However, remember that foam tapes are less durable than rolled vinyl, so they only offer a short-term solution to draughts. For more reliable long-term insulation, choose vinyl weather stripping for doors and windows. Not only do they have high moisture resistance, but they also provide excellent performance in both hot and cold weather.

In terms of purpose and application

In terms of purpose and application, foam weather stripping is best for sealing irregularly shaped windows and doors, especially in older homes. This is because foam compresses and expands well, offering flexibility. 

Plus, foam window seal tapes are available in different thicknesses and widths. So, whether you have to seal the area around your casement window stoppers or double-hung window rails, rest assured you can find one that will suit your weather-stripping needs. 

Meanwhile, vinyl weather stripping is best for sealing exterior doors and windows since it’s durable and can withstand harsh weather conditions. Specific applications include vinyl 'V' strips to seal door jambs and window sashes. 

In terms of installation

Installing weather stripping can take time and effort, especially for vinyl. To ensure that all the gaps in your doors and windows are properly sealed, hiring weather stripping services is the way to go.  

But, for DIY installation, foam weather stripping is easier because foam tapes have an adhesive backing. You have to peel off the backing and press the foam into place. Plus, you only need a pair of scissors or a sharp knife to cut the foam. When using a foam door seal, just make sure that the surface is completely dry,  clean, and grease-free for the adhesive to stick well.

Conversely, vinyl weather stripping has a more meticulous installation process. Your vinyl window weather strips should be correctly aligned to avoid gaps. Moreover, it requires more tools because aside from using a knife to cut your vinyl, you may also need a heat gun to ensure a proper seal. 

In terms of aesthetics

Although foam tape is available in different thicknesses and widths, it can still be more noticeable than vinyl because foam appears bulky when applied. You might also have difficulty blending foam tape into your existing decor because this weatherstripping material is only available in grey and white. 

Meanwhile, vinyl weather stripping offers a sleek appearance. You can fit your vinyl strips to flush against the surface when weatherstripping doors for a more integrated look. Additionally, vinyl strips can be painted to match and blend with your decor. 

In terms of cost

The total weather stripping cost for foam and vinyl depends on many factors, including the size of the gap you need to fill and the materials you need for the project. 

For the materials, both foam tapes and vinyl strips are generally affordable, with $14 for 17 feet for vinyl 'V' strips and $10 for 3 metres for foam strips. 

Moreover, you’ll also have to consider seal repair costs for your windows and doors, as your weather-stripping materials will likely degrade over time.
