By adding the rich appearance of hardwood flooring, the installation of composite hardwood flooring can significantly affect the beauty of the home. But to obtain a long-lasting professional effect, the laminate must be properly installed on top of a high-quality liner, which is the key to providing adequate support for the floor while protecting it from damaging moisture.

Most liners consist of two layers: a felt layer that provides cushioning and a moisture barrier that protects the floor from moisture and mold. The liner also has tape to help connect each laminate, ensuring that there are no gaps.

If you are considering installing laminate flooring and are looking for the best underlayment, read on to understand the features to consider when buying this material and understand why the following products are considered the best products you can use in laminate flooring project.

Choosing the right type of underlayment is critical to the successful installation of laminate flooring. There are three different types of cushions, each of which is suitable for certain types of subfloors. Keep in mind that some subfloors have additional padding, in which case you do not need to purchase or install pads.

As the name suggests, this type of cushion consists of a thin layer of foam that acts as a cushion between the laminate floor and the subfloor. This creates a cushion between the floors, minimizing noise, while providing more flexibility for those who walk on it. Foam padding does not provide a vapor barrier, so it should not be used in wet areas. Therefore, this type of liner is suitable for plywood and oriented strand board (OSB) subfloors.

The combination liner combines the foam layer with the vapor barrier to protect the laminate floor from moisture. The vapor barrier allows this type of liner to be used with concrete subfloors as well as OSB and plywood.

Cork is a high-quality liner used to reduce noise. It also has natural antibacterial properties to prevent mold growth between the laminate floor and the subfloor. Cork also provides sufficient cushioning, is a good insulator, and can absorb sound well. Cork is also much more expensive than foam or combination liners, almost twice the cost.

Choosing the right liner depends on many factors, including the type of subfloor it will cover. The thermal rating, thickness and sound absorption quality of the liner should also be considered.

The type of subfloor largely determines which type of underlayment you should use. The underlayment used for concrete floors requires a vapor barrier to prevent moisture from accumulating between the subfloor and the floor, which can lead to mold growth. In addition, please consider where the floor will be installed. The floor installed on the upper floor of a house or apartment should be lined to provide sufficient sound cushioning to prevent noise from reaching the floor below.

Pay attention to the R value of the gasket, which measures its insulating ability. The higher the R value, the better the insulation performance.

A cushion with a high R value can keep the floor warm in cold weather while preventing heat loss through the floor. Likewise, it helps to maintain air-conditioned air in the home in warm weather while preventing hot air from entering. Typical glass fiber insulation materials found in the exterior walls of houses have an R value of 3 to 5. Most pads have an R value of 2 or 3.

Many DIY enthusiasts may think that thicker padding creates a more cushioned feel. Although this may be the case for carpets, it is a fault for laminate flooring to use too thick cushioning material. Thick-bottomed cushions can over-bend the floor, causing the seams between the boards to separate. On the other hand, a laminate underlay that is too thin can make the floor noisy and hard. The thickness of the felt laminate liner should be between 2 mm and 3 mm to provide adequate cushioning while still maintaining adequate support for the floor. Cork liner is stronger than felt, so its thickness should be about twice that to provide adequate cushioning.

Laminate flooring can be quite noisy because it will bend on the subfloor. A good liner can provide a noise-reducing cushion between the two surfaces to prevent annoying squeaks. If you live in an apartment or condominium, sound absorption is a must to avoid conflicts with neighbors below. In fact, many apartments and apartment communities require cushions with the lowest sound level.

Some gaskets have sound transmission class (STC) and impact insulation class (IIC) ratings. The STC rating refers to the ability of a material to block air noise. The range of use is from 15 to 80. The larger the number, the better. The STC rating of standard wood flooring is approximately 40.

The IIC rating measures how much material blocks affect noise (such as moving footsteps or furniture). Hardwood floors without sound insulation have an ILC rating of approximately 45.

Floor cushions designed to reduce noise will raise the STC and IIC levels of the floor to the 1960s.

The gasket product selected here takes the above factors into consideration. They provide multiple layers to provide adequate support for the floating floor, while at the same time silencing, isolating and acting as an effective vapor barrier to prevent mildew.

Roberts’s product has multiple layers to increase protection, comfort and sound cushioning. It is one of the best all-round underlayments for laminate flooring. The core of this liner is its styrofoam bead layer, which acts as a cushioning system between the subfloor and the liner, while also leaving room for air flow to help prevent mold growth. The thickness of the product is sufficient to correct small imperfections in the subfloor and inconsistencies in the seams.

The moisture-proof layer can prevent moisture. A fairly large strip of adhesive makes installation easy. The strip allows enough 4 inches of overlap to prevent any gaps that might allow moisture to pass through. This cushion can also be used as an effective sound barrier, making it suitable for use on higher floors. Each roll provides 630 square feet of coverage.

For homes with wooden subfloors, a moisture barrier may not be needed, so this foam pad from Roberts is a suitable choice. The product uses 100 square feet of rolls, using 2.4 mm polyethylene foam, which can increase the cushioning effect, while eliminating small defects on the subfloor, making the installation of the composite floor more even. It can be used for radiant heating floors, and can be used for concrete floors when combined with steam barriers.

The price of this liner is also very reasonable; but remember, it does not include useful built-in tape that makes other products easy to install. Each roll is 25 feet long and 4 feet wide.

The liner has three layers to provide protection, comfort and sound absorption, making it one of the best combination liners you can lay on the floor. It includes a 3 mm thick layer, which increases the comfort of the laminate floor and also helps level uneven parts and seams in the subfloor. This thicker layer provides a good insulation barrier, making barefoot feel more comfortable in winter, and has excellent sound cushioning, making it an ideal choice for high-rises, apartments and apartments. The built-in moisture barrier makes this liner suitable for areas prone to moisture.

The combination of peeling and pasting adhesives and printed grids serves as a guide for arranging the paper, making installation easy. The large lip allows a large amount of overlap to prevent gaps between parts. This liner has a roll of 200 square feet.

With its sufficient thickness, this cork underlay can act as an excellent noise barrier while eliminating the defects of the subfloor. Remember that the cork liner must be thicker than felt to provide adequate cushioning, but since it is not as soft as felt, its extra thickness will still provide the support needed for floating floors. The cushion is 6 mm thick and has an STC grade of 61, which is suitable for the upper and lower layers.

It can also be effectively used as an insulator, helping to keep the floor warm in winter while preventing heat loss through the floor. Installation is easy: lay flat or glue on. Its excellent thickness also enables the product to prevent defects and cracks from being transferred from the subfloor to the laminate floor. This high-quality cork liner comes in 25-foot rolls.

With its excellent sound insulation quality and an impressive 66 STC rating, this thick felt mat from Roberts excels in preventing sound from being transmitted from the upper layer to the lower layer. Because it can absorb noise, this liner can also minimize the noise in the room and suppress the sound that spreads to other rooms.

The 3 mm thick liner also creates a sense of cushioning for the laminate floor, and plays an effective thermal insulation role to keep the floor warm in winter. The film overlay adds a moisture barrier to protect the floor from mold growth. Due to the 3-inch built-in overlap between the components, this gasket is easy to install without gaps.

Roberts First Step was selected for its ability to cover ample square feet, moisture wicking ability, built-in tape, and 4-inch overlap, and is our overall first choice for the best laminate liner. If your floor type requires stronger moisture and sound insulation, then Roberts Serenity foam padding is a more suitable choice.

Floor underlays can help enhance the sound insulation of your home, reduce the possibility of mold, and can help level the dents and/or bumps on your current floor. Each of the above products can help treat some or all of these floor-related diseases, some of which have the advantage of some additional special features.

For example, some of the above options use up to 630 square feet of material to cover the largest surface area of ​​your home, while other options are made of moisture-absorbing and mildew-resistant road barriers, suitable for high-density houses or rooms. humidity. In addition, you can also check out some of these preferred materials for extra thick materials up to 6 mm to provide extra padding on uneven floors.

Finally, due to the built-in tape and overlap for full coverage and reliability, some of these liners are also easy to install in the trailer. However, be sure to check pads that do not have these features, as they may require the accompanying glue or other adhesives during installation.

If you still have questions about the thickness of the liner, how to install the liner, or why it is so important, please read on for the answer.

The thickness of the laminated liner is usually between 2 mm and 3 mm, of which 3 mm can provide sufficient cushioning and insulation without affecting the seams between the boards.

Unfold the liner, making sure that the white adhesive side is facing up. This allows overlapping parts to be connected. If the white tape is facing down, the bottom layer is upside down.

Underlayment is a requirement for laminate flooring. The liner allows the floor to float, prevents it from creaking, provides stability, and ensures that the locks between the boards are well supported. Skipping the liner will actually damage the floor.
