  • Custom Fit: Polyurethane foam insulation can be sprayed or injected, ensuring a perfect fit for any garage door type or size.
  • Lightweight: Despite its rigidity, it adds minimal weight to the door, maintaining smooth operation.
  • Environmentally Friendly Options: Many polyurethane foam products are now made with eco-conscious materials, further enhancing their appeal to sustainability-focused homeowners.

Conclusion

Polyurethane foam insulation is a game-changer for garage doors, offering unparalleled benefits like energy efficiency, durability, noise reduction, and weather resistance. While the upfront cost may be higher than other insulation types, the long-term advantages make it a worthwhile investment for homeowners seeking a more comfortable and efficient living space.

If you’re considering polyurethane foam insulation for your garage door, consult a professional installer to ensure proper application and maximum benefits. By doing so, you’ll enjoy a garage that’s functional and a key contributor to your home’s overall energy efficiency and comfort.

Foam Weather Stripping vs Vinyl: Which Is the Better Choice?

Insulation is essential to maintain a comfortable temperature indoors. One way you can ensure adequate insulation is by sealing the gaps around doors and windows through weather stripping. 

Weather stripping prevents draughts and heat loss, helping keep indoors feel pleasant to lounge around. You can find various materials for weather stripping, but ultimately, you’ll have to come down to just one. To help you choose, here’s an in-depth comparison between the most popular weather stripping materials, foam weather stripping vs vinyl. 

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 weatherstripping 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.

Recommendation:  Vinyl weather stripping offers better weather protection.

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.

Recommendation: Vinyl weather stripping provides a long-term solution to improve insulation.

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. 

Recommendation: Choose foam weather stripping for sealing irregularly shaped windows and doors, and vinyl weather stripping for sealing exterior doors and windows. 

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. 

Recommendation: Foam weather stripping is easier to install

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. 

Recommendation: Choose vinyl weather stripping for a more integrated and sleek appearance.

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 £5 for 5 metres for vinyl strips and £11 for 2.5 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. 

Recommendation:  Materials for both weatherstripping types are generally affordable, but you must consider other costs, like labour and repair.
