Underfloor Insulation Glasgow

Suspended Flooring Insulation & Floor Insulation Installers Glasgow

Underfloor Insulation in Glasgow

Underfloor insulation is far more effective that it may sound, when you ask most people about home insulation their first thoughts are internal wall, loft and roof insulation. Underfloor insulation compliments these other types of insulation well, with a large majority of the jobs we install are having their floor and loft insulated at the same time.

At the very minimum a further 10% of heat is lost through the ground via uninsulated floors. You can insulate wooden suspended flooring (also known as timber suspended flooring) and concrete floors as long as there is a hatch to access crawl space underneath your floor, that provides enough access for one of our insulation installers to move around.

Should we not be able to locate a hatch or if there is any other reason the underneath of your floor is not accessible, we will need to lift the carpet or hard flooring and the underlay and install that way. This can be a rather messy process and understandably some people decide to not have underfloor insulation installed if there is no access via a hatch.

Why should I insulate under my floor?

As previously stated, normally when people are considering having their floor insulated they either have had their loft and walls done already or are getting them all done at the same time. Although floor insulation provides its own benefits, having your loft and / or walls insulated and not having your flooring done, undermines your current insulation to some extent. If you want your full home properly insulated, underfloor insulation is essential to achieve this!

    What is Underfloor Insulation?

    Underfloor insulation is literally when you insulate underneath the floors of your home and can be carried out on wooden / timber suspended flooring and concrete floors. To install underneath concrete floors, you need to have a small hatch, normally found in your kitchen (what used to be the pantry) which will provide reasonable access for one our underfloor insulation installers to crawl around and be able to install some insulation. Generally speaking around 2 metres is an ideal size of space to carryout an installation.

    Much like loft insulation, we can use a variety of materials including Knauf Earthwool and Rockwool products, sheep’s wool insulation, foil insulation, PIR rigid insulation boards or spray foam insulation.

    How Does Floor Insulation Work?

    People sometimes expect to be able to feel extra heat from their floors, this is not really the case and more related to underfloor heating. This is somewhat true if your floors are not insulated and close to the cold ground, especially with concrete flooring, rather than your floors being noticeably warmer when insulated, they can be noticeably freezing cold when uninsulated! 

    Underfloor insulation helps to reduce heat loss and further compliments other types of home insulation to improve heat retention.

    Unlike loft and internal wall insulation, floor insulation doesn’t trap heat in a certain space as such, certainly not when its installed on its own. It works to reduce heat loss using a controlled air flow barrier, stopping colder air from being able to get in from outside and also preventing warm stuffy air entering during the warmer months.

    In terms of heat retention it does still trap warmer air thats been heated by your homes central heating to a degree, but not as effectively as loft, roof or wall insulation.

    Think of a thermal flask, that acts as a vacuum, keeping warm coffee hot and cold water cold, the same applies to the rooms of your home that have effective insulation installed on all areas.


    Underfloor Insulation Benefits

    There are a wide range of benefits to having insulation installed underneath your floors, the leading benefits are listed below:

    Less warm air will escape from under your flooring, keeping your home warmer indoors, especially at night when your central heating is turned on.

    Investing in insulation under wooden floors can lead to significant long term energy and heating bill savings. By reducing heat loss through the floor, your heating system doesn’t have to work as hard to maintain a comfortable temperature. This results in lower energy consumption and reduced heating bills. Over time, the savings can accumulate, making the initial investment in insulation under wooden floors well worth it.

    Underfloor insulation is an effective way to improve your homes EPC (energy performance certificate) rating. It is recommended that homes in Scotland have an EPC rating of D or higher.


    One of the primary advantages of insulating under wooden floors is the improved energy efficiency it provides. By adding insulation in this area, you can minimise heat loss through the floor, preventing cold air from infiltrating your living space during the winter months.

    Insulation acts as a barrier, reducing the transfer of heat between the floor and the space below. As a result, your heating system can operate more efficiently, and you can maintain a consistent and comfortable indoor temperature.

    Insulating under wooden floors can have a direct impact on the thermal comfort of your home. Without insulation, cold air from the crawl space or basement can seep through the floorboards, creating drafts and making the living space feel chilly and uncomfortable. By installing insulation, you can create a thermal barrier that helps to keep the floor warmer and minimises the cold air infiltration, providing a more pleasant living environment.

    In addition to energy efficiency and moisture protection, insulating under wooden floors can also offer soundproofing benefits. The insulation material helps to absorb and dampen sound vibrations, reducing airborne noise transmission between floors.


    This can be particularly beneficial in multi-story homes or buildings with shared living spaces, where sound privacy and noise reduction are desired.


    In conclusion, insulating under wooden floors is a worthwhile investment that brings numerous benefits. Improved energy efficiency, enhanced thermal comfort, energy cost savings, moisture protection, and soundproofing advantages make it a valuable addition to your home.

    Insulating under wooden floors can also provide protection against moisture related issues. By creating a barrier between the floor and the crawl space or basement, insulation helps to prevent moisture from rising into the floorboards. Excess moisture can lead to rot, mold growth, and damage to the wooden structure. Insulation acts as a moisture barrier, minimising the risk of these issues and contributing to the longevity and durability of your wooden floors.

    Effective underfloor insulation will reduce dampness both in the air and on areas of your floor that are insulated.

    It is a well known fact that hot air rises, underfloor insulation helps create a barrier on your floor from the ground underneath, keeping the air a nice temperature during hot summer months as well keeping the cold winter air out!


    Suspended Floor Insulation Glasgow

    Suspended flooring is very common in homes in Argyll and Bute and throughout Scotland. Lots of suspended flooring was installed in Argyll and Bute during the 18th and 19th century as an effective way to separate peoples homes from the cold ground. In some ways you could say the invention of suspended flooring was one of the first types of insulation to exist.

    Suspended Timber Floor Insulation

    Suspended timber floor insulation is most often installed via a hatch underneath your floor which can allow for your floors joists to be partially insulated from underneath. 

    The other options is to lift your floor boards, which is only suitable if they are in good condition so they can be safely reinstated with some thermal insulation installed underneath. 

    Best Underfloor Insulation Material

    When it comes to floor insulation, selecting the right option is crucial for maximising energy savings and improving thermal efficiency. In this section, we will explore the most effective and efficient options available, taking into account factors such as material performance, insulation thickness, and installation methods. By understanding these considerations, you can make an informed decision that aligns with your energy-saving goals and ensures long-term comfort in your home.

    Best Material For Performance

    Different insulation materials offer varying levels of performance in terms of thermal conductivity, moisture resistance, and durability. Explore options such as fiberglass, mineral wool, foam boards, and sprayed foam insulation. Assess their R-values (thermal resistance) to determine their effectiveness in reducing heat transfer and enhancing energy efficiency.

    Fiberglass Floor Insulation

    Fiberglass insulation is a popular and affordable option. It is widely available, easy to install, and offers good thermal performance.

    Mineral Wool Floor Insulation

    Mineral wool, also known as rock wool or stone wool, is another cost effective choice. It provides excellent thermal insulation, soundproofing, and fire resistance.

    Cellulose Floor Insulation

    Cellulose insulation, made from recycled paper, is an environmentally friendly and affordable option. It can be blown into cavities or installed as loose-fill, offering good thermal insulation.

    Best Floor Insulation Thickness

    Insulation thickness plays a significant role in achieving optimal energy savings. While thicker insulation generally provides better thermal resistance, it’s essential to strike a balance to avoid unnecessary costs or difficulties in installation. Consider factors such as available space, building codes, and desired insulation performance when determining the appropriate thickness for your floor insulation.

    Underfloor Insulation Installation Process

    Insulating an existing floor is a practical and effective way to enhance energy efficiency and maximise energy savings in your home. Whether you have a wooden floor or a concrete floor, proper insulation can minimise heat loss, improve thermal comfort, and reduce energy consumption. In this section, we will provide you with step-by-step guidance on how to insulate an existing floor effectively.

    Step 1: Assess the Current Condition

    Before you begin the insulation process, it’s essential to assess the current condition of your existing floor. Look for signs of damage, such as rot, dampness, or pest infestations. If any issues are present, address them before proceeding with insulation. Repairing the floor’s structural integrity is crucial for long term success.

    Step 2: Choose Suitable Insulation Materials

    Selecting the right insulation materials is key to achieving effective floor insulation. The choice of materials may vary depending on the type of floor you have:

    • Wooden Floors: For wooden floors, consider using insulation batts or rolls made of materials like mineral wool or fiberglass. These materials provide good thermal performance and are easy to handle and install.

    • Concrete Floors: If you have a concrete floor, rigid foam boards or spray foam insulation are often recommended. These materials offer excellent thermal insulation properties and can be applied directly to the concrete surface.

    Consult with our insulation professionals to determine the most suitable insulation materials for your specific floor type.

    Step 3: Prepare the Floor Surface

    Proper preparation of the floor surface is essential for optimal insulation installation. Clean the floor thoroughly, removing any debris, dust, or obstructions. Ensure that the surface is dry and free from moisture, as this can affect the performance and longevity of the insulation.

    Step 4: Install the Insulation

    The installation process will depend on the type of insulation material you’ve chosen. Follow these general guidelines:

    • For insulation batts or rolls: Measure the floor joist spacing and cut the insulation to fit snugly between the joists. Install the insulation, making sure there are no gaps or voids. Use insulation supports or netting to hold the insulation in place if necessary.

    • For rigid foam boards or spray foam insulation: Cut the insulation boards to fit the floor dimensions and adhere them securely to the floor surface. Pay attention to proper air sealing and insulation continuity to minimise heat loss and maximise energy efficiency.

    Step 5: Seal Air Leaks and Gaps

    To ensure the effectiveness of your floor insulation, it’s crucial to seal any air leaks or gaps. Use caulk or foam sealant to seal around openings, such as pipes, electrical outlets, or gaps between the insulation and the floor surface. This will help prevent air infiltration and maintain airtightness.

    Step 6: Assess and Enhance Vapour Barrier

    If your floor is above a ventilated crawl space or basement, consider installing or improving the vapour barrier. A vapour barrier helps prevent moisture from migrating into the insulated floor assembly, reducing the risk of condensation and potential moisture related issues.

    Step 7: Monitor and Maintain Insulation

    Once your floor is insulated, regularly monitor its condition and address any maintenance needs promptly. Insulation can settle or deteriorate over time, impacting its effectiveness. Regularly check for signs of damage or deterioration and make necessary repairs or replacements as needed.

    By following these step-by-step guidelines, you can effectively insulate your existing floor and maximise energy savings. Proper insulation installation ensures improved thermal comfort, reduced energy consumption, and a more sustainable and comfortable living environment. Consult with our insulation installers for personalised guidance and to ensure compliance with local building codes and regulations.
