Some underlays may also provide thermal protection, although it is important to note that because it is installed over the subfloor, rather than underneath it, it will never provide quite the same level of assistance in this department as purpose built, properly installed insulation.
An underlay provides insulation
Laminate can make the floor feel colder in the winter, especially when it's installed on a cold subfloor. A laminate underlay provides some insulation, meaning the floor's not quite as cold on your feet.
Underlayment has thermal properties that can increase the warmth of the floor. Select an underlayment with a thermal R rating to help keep your floors warm. Know that underlayment can only do so much to keep your floors warm, especially on concrete floors in your basement.
There are many benefits from using an underlay. Heat loss through the floor can be up to 15% - underlay will reduce heat loss through the floor, but some underlays are better than others. Thermal Insulation is measured in 'Tog' - think duvets - for reducing heat loss, a high Tog rating is good!
DRICORE Insul-Armor is the most premium subfloor. With an R-value of 4.1, DRICORE Insul-Armor provides one of the highest R-values in the market, meaning maximum warmth and comfort for your family.
Basement flooring options that provide the best insulation include: cork, EVA foam, PVC, and plastic. With numerous suitable options manufactured using a variety of these materials, there is an option or flooring package for every price point.
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
Some underlays may also provide thermal protection, although it is important to note that because it is installed over the subfloor, rather than underneath it, it will never provide quite the same level of assistance in this department as purpose built, properly installed insulation.
Top underlays to help you stay warm
A modern underlay can make a big difference when it comes to improving your home's insulation and therefore improving its energy efficiency.
That's why, for most projects, we typically recommend the Plushwalk 12mm Carpet Underlay. This is the best thermal carpet underlay to date. It boasts an exceptionally high TOG rating of 3.5 and benefits from a 12mm thick, memory foam construction. It will make a huge difference to the temperature of the room.
Vinyl tiles are good for warmth as they are made up of multiple levels of material, making them good insulators. Just like wood flooring, most vinyl flooring is compatible with underfloor heating too. So keeping your home warm really isn't a problem with vinyl flooring.
Professionals insulate a cold concrete floor by applying a layer of rigid foam insulation board directly onto the concrete surface, followed by a subflooring material like plywood or OSB (oriented strand board).
Underlayment provides a smooth, level surface for when installing your final flooring. It serves several other functions, including sound deadening and softening the feel of the floor underfoot. It can also act as a moisture barrier and protects against mold and mildew.
Carpet, particularly wool and shag varieties, provides the best R-values among all standard flooring choices.
The Critical Role of Vapor Barrier Underlayment
Vapor barrier underlayment, also known as moisture barrier underlayment, is designed to prevent moisture from seeping into your floors. In regions where humidity levels fluctuate, or in installations over concrete subfloors, the risk of moisture damage is significant.
Yes, underfloor insulation is a good idea. Underfloor insulation helps to reduce heat loss in winter and heat gain in summer from and to your home. Reducing the need to heat and cool your home will also reduce your energy bills and carbon emissions.
Keeping Your Floor Warm from Cold Concrete
Thermal properties of underlayment can help keep your floor warm. The thermal properties are all considered by the material the underlayment is made up of. Fiber/felt underlayment offers the best bang for your buck for thermal properties providing almost 200% more.
Although many homeowners focus primarily on the surface and aesthetics, using the ideal underlayment provides extensive benefits, from sound reduction and compression resistance to moisture protection and insulation.
Sandwiched between the subfloor and laminate, this adds a much-needed extra layer of cushioning – which enhances underfoot comfort, keeps the heat inside the room and improves the temperature of your laminate. The thicker the underlay is, and the higher its TOG rating, the more thermal insulation it'll provide.
In general, carpets without underlay have a much shorter lifespan and are more at risk of rapid wear and tear. Underlay is especially important if you're planning on laying carpet over concrete as it will help make walking across the room much more comfortable.
For underfloor insulation, moisture resistance and compressive strength are crucial. Extruded polystyrene (XPS) and expanded polystyrene (EPS) are excellent choices. They are durable, moisture-resistant, and provide high R-values. Reflective foil insulation can also be effective, especially in reducing radiant heat.
A high-quality underlay offers thermal insulation, acoustic insulation and cushioning.
It's essential to wear protective clothing and a mask when installing fibreglass insulation to prevent any health risks. Overall, fibreglass insulation is the cheapest and most effective insulation option available, making it a popular choice for homeowners and builders alike.
It is quite common to aim for a U-value of 0.18 when insulating both domestic and non-domestic floors. A common approach to achieve this low U-value is by using a generous layer of Rigid PIR Insulation.
The optimal R-value for most homes is 30, but you can go as high as 38 if you live in a tropical climate. Anything higher than 38 indicates an over-insulated space. While you might think that too much insulation can't be bad, there are some significant consequences to consider.
