Under Floor Insulation

Spray foam insulation is the optimum solution for under floor insulation because it provides a high R-value, a vapour barrier and seals cracks and crevices.

Spray foam is excellent for use as an underfloor insulator and has several key advantages over conventional insulation solutions. Our applicators are trained and qualified to work in confined spaces, so we can install insulation in some of the more difficult-to-access spaces.

    Spray Foam Under Floor Insulation

    When it comes to keeping your home warm in the winter and cool in the summer, insulation is key. Without it, your energy bills could skyrocket – and your comfort levels could plummet. Underfloor insulation is essential since heat can easily escape through the floor. One of the best solutions for underfloor insulation is spray foam insulation.

    What is Spray Foam Insulation?

    Spray foam insulation is a type of insulation made from two components: polyurethane and isocyanate. When these two components are combined, they create a chemical reaction that causes the mixture to expand and harden. The result is a foam material that gets sprayed onto the surface to be insulated, filling all the gaps and creating a seamless, airtight barrier.

    At NZAS, we know the ins and outs of insulation, and we are fully trained and equipped with the right products to ensure we carry out the installation of quality underfloor insulation effectively. Get in touch with us today.

    Advantages of Spray Foam Underfloor Insulation Products

    There are many advantages to using spray foam insulation for underfloor insulation. Here are just a few:

    No Sagging, Unlike Batt Underfloor Insulation Options

    Spray foam insulation is the more reliable choice for underfloor insulation, compared to batts insulation. That’s because it doesn’t sag or settle over time, maintaining its R-value and providing consistent thermal resistance. Traditional batt insulation, on the other hand, can shift and compress over time, leaving gaps and reducing its effectiveness.

    With spray foam insulation, you can have peace of mind knowing that your underfloor insulation will remain intact and provide optimal thermal insulation underneath your flooring for years to come.

    High R-Value Per Millimetre

    Spray foam insulation has a high R-value per millimetre, which makes it an efficient option for underfloor insulation. That means that it can provide the same level of insulation with less material below your flooring, compared to other types of insulation. As a result, you can achieve the same level of insulation with a thinner layer of spray foam insulation, which translates to cost savings.

    Additionally, the high R-value per millimetre allows for a more versatile application of insulation – particularly in areas with limited space for installation. With spray foam insulation’s superior insulation properties, you can achieve optimal energy efficiency and comfort levels in your home without sacrificing cost or storage space.

    Seals Cracks and Gaps

    One of the most significant advantages of spray foam insulation for underfloor insulation is its ability to fill all the cracks and gaps in the surface being insulated. That ensures there are no air leaks in your flooring that can lead to heat loss, which can result in higher energy bills and discomfort.

    The expanding nature of the foam creates a seamless barrier that prevents any air from escaping, keeping your home warm in the winter and cool in the summer. This also means that spray foam insulation can help to reduce noise levels and improve indoor air quality by keeping out outdoor pollutants and allergens.

    At NZAS, we have a thorough understanding of insulation and are fully trained and equipped with the necessary products to ensure the successful installation of high-quality underfloor insulation. Don’t hesitate to contact us.

    Underfloor Insulation Sections off Hot and Cold Areas

    In addition to preventing heat loss and air leaks, under floor spray foam insulation prevents draughts from entering your home. Draughts can cause cold spots, making your home feel uncomfortable and forcing your heating system to work harder to maintain a comfortable temperature.

    With underfloor spray foam insulation, however, all gaps and cracks are sealed, preventing unwanted air from entering your home through the flooring. That not only helps to keep your home more comfortable but also more energy-efficient, as your heating system doesn’t have to work as hard to maintain a consistent temperature. As a result, you can enjoy a more comfortable living environment while reducing your energy bills.

    Acts as a Vapour/Moisture Barrier

    Another advantage of spray foam insulation for underfloor insulation is that it acts as a natural vapour barrier. That means it can prevent moisture from penetrating the insulation and causing damage, such as mould growth, which can be hazardous to your health.

    The closed-cell structure of the foam provides a continuous barrier that helps to keep moisture out – protecting the structural integrity of your home and ensuring that your insulation remains effective for years to come. Additionally, the natural vapour barrier properties of underfloor spray foam insulation help to maintain optimal indoor air quality, which is especially important for individuals with respiratory conditions or allergies.

    Requirements for Underfloor Insulation

    Current building standards require underfloor insulation in residential properties to have a minimum R-value of 1.3. That means the insulation must provide a certain level of thermal resistance to meet energy efficiency requirements. With spray foam insulation, this level can be achieved with only 28mm of foam. You can achieve the same level of insulation with less material, making spray foam insulation a more cost-effective solution.

    Keep Your Home Warm With Underfloor Insulation

    To insulate under floors is an effective way of improving the energy efficiency and comfort of your home. Heat loss through the floor can account for up to 15% of a home’s energy consumption, making underfloor insulation a valuable investment. Here are some of the reasons why underfloor insulation is so effective:

    1. Prevents Heat Loss: Insulating under floors helps to prevent heat loss through the floorboards, keeping your home warmer and reducing the need for heating, leading to significant cost savings on your energy bills over time.

    2. Increases Energy Efficiency: By reducing the amount of heat lost through the floor, underfloor insulation can help to increase the energy efficiency of your home. This can have a positive impact on the environment by reducing your carbon footprint.

    3. Improves Comfort: Insulation under floors can also improve the comfort levels in your home. It can help to reduce draughts and cold spots, making your home more comfortable to live in.

    4. Reduces Noise Levels: Underfloor insulation can also help to reduce noise levels in your home by acting as a sound barrier. This can be particularly beneficial if you live in a noisy area – or have noisy neighbours.

    5. Protects Against Moisture: Insulation under floors can also protect against moisture and dampness. It can help to prevent moisture from penetrating the floorboards, which can lead to damage and mould growth.

    Overall, insulating under floors is an effective way to improve the energy efficiency and comfort of your home. It can help to reduce your energy bills, increase your home’s value, and create a more comfortable living environment. With the many benefits of underfloor insulation, it’s no wonder why it’s become a popular choice among homeowners.
