2mm IXPE Foam Underlay With Holes With Silver Aluminum Film For The Heating System
Underlayment is a layer used when installing laminate floor and engineered hardwood floors. Underlayment comes in several types and qualities. It is real important to understand the difference in underlayment quality and their function
WHAT IS UNDERLAYMENT:
Underlayment is required for installation of Engineered or Laminate Flooring. Underlayment is layers of foam, paper, rubber, felt & cork which is install between subfloor and new floor. Will help for sound protection and provide a good insulation.
WHEN TO USE UNDERLAYMENT:
Underlayment must be used for floating installation of Laminate and Hardwood flooring. When installing Laminate or Engineered Hardwood flooring it is not only required to use underlayment, but also required to install a vapor barrier if over concrete sub-floor.
WHY & WHEN TO USE UNDERLAYMENT:
Using underlayment for installation of Laminate and Hardwood Floors reduces sound and feels comfortable under your feet. In any installation of floating floors a proper underlayment should be used. Some underlayments have been designed to protect against mildew, mold and moisture.
WHERE TO USE UNDERLAYMENT:
Underlayment is installed over slab or plywood sub-floors. If installing underlayment over concrete slab it is required to use a vapor barrier first. Sub-floor surface must be clean and dry before installation. Underlayment can be used for any installation. Condo owners are required to check the sub-flooring, if the sub-floor is concrete it will require an underlayment with moisture barrier. Before you install any Hardwood or Laminate you need to check with your Home Owners Association because most condo & apartment groups require special Acoustical underlayments with special sound prevention properties.
HOW TO SELECT UNDERLAYMENT:
Choosing underlayments is critical, first you need to follow floor manufacturing recommendations for approved underlayment. In general flooring underlayment comes in 4 major categories.
FOAM UNDERLAYMENTS:
Foam underlayment is a thin layer of foam which is called standard underlayment. This type of underlayment offers a minimum comfort and sound reduction. It can not be used when installing Laminate and Hardwood floors over a concrete sub-floor. When you are using the foam underlayment in buildings with concrete sub-flooring, it is required to use plastic (polyethylene film) with 6 mm thickness.
2 IN 1 UNDERLAYMENT OR FOAM / FILM COMBO UNDERLAYMENT:
Combination of standard foam underlayment with plastic is called Foam/Film Combo or 2 in1 underlayment. The plastic layer functions as a moisture barrier layer. When installing laminate floors or Engineered Hardwood flooring the plastic side should go down over the concrete floor. The 2 in1combo underlayment prevents the moisture from the concrete to get into the flooring products. This type of underlayment comes in different thickness and sized rolls. It has a good moisture barrier, but is not a great sound reduction product.
MODIFIED UNDERLAYMENT - ACOUSTICAL
UNDRLAYMENT:
Modified underlayment is an upgrade underlayment which is a thicker underlayment, designed for superior sound absorption, and to provide maximum walking comfort. Some of the higher grade modified underlayment prevents moisture, mold and mildew. Modified underlayment can be used in any building, condo, apartment, high raise buildings, residential homes and commercial spaces. Notice to condo and apartment owners: When installing Hardwood Floors or Laminate Flooring in second or higher floor, you need to check with your Home Owners Association rules for their requirement & recommended type of underlayment.
