These membranes are not characterized by ANSI or ISO standards but must achieve 50 psi or greater shear bond strength in seven days per the test method in ANSI A118.12 Section 5.1.3. But there are many different types of roofing underlays on the market – so how do you know which product is the right choice for your project? Schluter DITRA Matting protects the substrate against damage due to moisture penetration and aggressive substances. To achieve a fully certified bonded waterproofing assembly with the tile covering, use the waterproofing membrane sealing band Schluter KERDI KEBA (minimum width: 125mm) on the abutting joints, solidly embedding it in Schluter KERDI COLL L Sealing Adhesive. The sealing band should overlap at least 5 cm.

I want to lay tile over a plywood subfloor in my kitchen/living room. The floor is structurally sound with trusses on 12" centers beneath. Want to be able to have a piano, entertainment center, kitchen table, couch, and china cabinet sit on and be moved around on this floor with appropriate protection/sliders. What is my best option for underlayment? I want to make sure it is best for the load of the furniture. I presume it should also have some waterproofing qualities because of the kitchen.

What Is It?

Meanwhile, BS 5250 says that, in the case of LR vapour-permeable underlays, designers must ensure that the manufacturer’s stated water vapour resistance values are suitable for the application. These types of underlay should also comply with BS EN 13859-1 or have third-party accreditation, such as a BBA certificate. The benefits of Marley roof underlays If the floor surface, be it wood or concrete, is not flattened or leveled to meet industry requirements and standards prior to starting the installation, chances are high that problems will be encountered. Likewise, wall surfaces need to be properly prepared to eliminate potential issues. Three Types of Underlayment for Tile

But guess what? Ditra gets the last laugh as every other company now has an imitation alternative to Ditra for tile floors in their lineup. Interior installation specifications are housed in ANSI A108.11, while the material specifications are found in ANSI A118.9 or ASTM C1325.


The type of bonding adhesive used to apply Schluter DITRA Matting depends on the type of substrate. The adhesive must bond to the substrate and mechanically anchor the fleece on the underside of the matting. Verify the compatibility of all materials prior to installation. So, with these basics out of the way let’s move on to tile underlayment. Beginner’s Guide to Tile Underlayments The only time an underlay is required is if there is a need to alter acoustics underfoot. In this rare case, the system needs to be dual bonded and typically needs to be a shredded rubber underlay of a very high density. This is the same rubber underlay that is used for timber and tile flooring also, and this rubber is composed mainly of shredded car tires compacted very densely. High-density underlay is needed for vinyl becuase the transfer of weight under foot goes straight through to the underlay.

This kind of underlay is also underfloor heating compatible, so you can enjoy toasty toes all year round! Things are different here because of the differences in timber installation methods. In some cases, Timber Floors require underlay and in other cases, they don’t. If you’re looking for an affordable underlay to fit under a wood or laminate floor, foam underlay is the way to go. It’s comfortable to walk on, provides cushioning underfoot, absorbs sound and does a great job of keeping your room warm. To obtain a floor or wall surface that is flat enough to receive tile, surface irregularities need to be corrected pertheANSI Specification A108.02-, Subfloor Surfaces detailed above.
