What are Floor Insulation Boards?
10% of household heat is lost through the floor. Insulation is the go-to option for people who want to improve the thermal envelope inside their homes by reducing the U Value of their floor, wall or roof, in line with current building regulations. Floor insulation boards are focused on keeping your home warm. If you are looking for insulation to provide fire resistance, then Rockwool Insulation is a better choice.
Floor insulation boards are ideal for homeowners who have suspended floors, as the insulation can be placed in the space underneath the floor. Suspended timber floors have a gap between the floorboards and the foundations of the home. They can also be used to block gaps in skirting boards. Suspended floors increase heat loss, which means that homeowners pay more to heat their homes. Lots of people invest in floor insulation in a suspended wooden floor because the boards reduce heat loss and therefore reduce your overall energy bill.
Boards are rigid yet versatile. You can cut floor insulation panels into different shapes with ease. No matter what your floor insulation requirements are, you can manipulate our products to suit your needs. They are lightweight and rigid, which makes them easy to handle and install.
Floor Insulation Board Types
We sell a range of the most popular floor insulation boards. A lot of people prefer boards because they are easy to manipulate and cut to size. Insulating screed and polyurethane spray are two of the other most popular floor insulation options, but they are not as efficient as insulation boards.
Our customers can choose from a range of materials. Follow this guide to find out which material best suits your insulation needs.
● EPS - Expanded polystyrene (EPS) is an insulation material manufactured from a mould that is filled with small foam beads. It can improve the u-values and thermal properties of your home, but is the lowest thermal performance of all insulation boards, with a thermal conductivity of 0.038 W/mK.
● XPS - Extruded polystyrene insulation (XPS) is made by melting together plastic resin and other materials. The resulting liquid is extruded and expands during the cooling process. XPS boards are leak-resistant, environmentally friendly, have high compressive strength, and stop the need for a vapour control layer.
● PIR - Polyisocyanurate (PIR) insulation is the most popular floor insulation board on the market. These rigid foam insulation boards are commonly used in the floor because of their thermal properties. With a thermal conductivity of just 0.022 W/mK, they are highly thermally efficient and will retain heat well.
● Phenolic - Phenolic floor insulation boards are the holy grail of thermal insulation boards. They have over 90% closed-cell formation. This dense material is water-resistant and has fire retarded properties. Phenolic panels do not age when exposed to direct sunlight. Manufactured by Kingspan, the Kooltherm K103 Floorboard is a premium floor insulation board with a thermal conductivity of just 0.018 W/mK. These boards should be used when the ultimate thermal protection is required.
Floor Insulation Board Thicknesses
Different floor insulation thicknesses are best suited to different insulation needs. We stock boards that range from 20mm to 150mm. If you purchase a thicker insulation board, you can increase the thermal value of the build-up of products. Sometimes, due to space restrictions, you may have to opt for a thinner board. All our boards have excellent thermal conductivity properties. With our wide range of floor insulation thicknesses, you can always find an effective board that fits your space.
Frequently Asked Floor Insulation Board Questions
How do Floor Insulation Boards Work?
Floor insulation boards provide a barrier between the structure of your home and the floorboards. The newer homes are normally have a concrete ground floor, boards can be placed on them too. There are lots of options available to homeowners who have specific needs for their unheated spaces. You can purchase insulation boards for loft floors, floor insulation for under laminate or wooden floors, and floor insulation for under solid floors and solid concrete floors.
Floor insulation panels fill the gaps in suspended timber floors and can be installed between the floor joists. By filling the gaps of such floors with high-performance thermal materials, homeowners can reduce their overall energy bills and stay warmer for longer.
Are Floor Insulation Boards Worth It?
Floor insulation costs can seem daunting, whether they're for new build or refurbishment projects. You can recover the initial investment in anywhere from three to five years depending on the overall thermal conductivity of the materials you use.
We recommend underfloor insulation boards for people who can afford to invest in their properties long term. Despite there being an initial recovery period, you will see the benefits of your new insulation almost immediately. You can save around 10% on your heating bills all year round when you install underfloor rigid insulation boards.
How to Lay Floor Insulation Boards?
Floor insulation installation does not have to be difficult. Follow these floor insulation installation tips for your project.
● Prepare the floorboards - Clear any debris and dust away. You might have to use a layer of plywood to ensure the floor level is flat.
● Prime solid floor - You need to prime a concrete floor before you lay insulation boards. Thermal primers can help to further reduce the loss of heat from your home. If you are laying insulation under timber floors, you do not have to worry about primer. You can also lay a damp proof membrane below or above the floor.
● Cut the boards - You can cut floor insulation with a standard utility knife. We recommend marking your measurements on the board before cutting to avoid mistakes.
● Place the boards - You should stagger insulation boards to reduce drafts. If you are laying solid floor insulation, use an adhesive to secure them in place. For a suspended timber floor, we recommend screwing the boards into place at 300mm intervals across the floor space. It's important not to block air bricks.
● Seal the joints - You need to make sure that the seams between the joints are sealed. Lots of people use waterproof tape to seal the joints. Some people go the extra mile and use acrylic sealant before the tape.
You should always consult a professional for non-standard insulation projects.
