Factory-side guides to choosing XPS tile backer boards: thickness selection, material comparisons, and specification checks before you order.
A tub to shower conversion can sometimes keep the existing drain. The answer depends on the drain center, the alcove, the tray geometry and the connection below the floor—not on the words “offset drain” alone. That is good news if the new shower stays in the old tub footprint. It is not permission to order…
A buyer can see “71 models” on an IAPMO PS 106 report and reasonably assume that all 71 were individually put through every test. Our report does not support that wording, so we will not use it. Report J251017003-1 lists 71 models and identifies the specific samples tested. It also states that the report applies…
A 6mm XPS backer board belongs in an assembly that already has continuous support. It is a thin, coated tile substrate for a solid-backed wall or a suitable sheet substrate. It is not the thickness we would choose to span open framing and ask the board to supply the missing stiffness. That distinction decides whether…
If your order is mainly 48 × 96 inch boards, we already have a thickness-by-thickness loading table for a 40HQ. If it combines 36 × 60 and 48 × 96 boards, do not stretch that table by area ratio and call the result a loading plan. A workable 40HQ loading plan starts with four things:…
Last week, a buyer from the UK emailed us seven questions before placing a trial order for XPS tile backer boards. Good questions. The kind that separate a factory from a middleman, and a serious buyer from a browser. Instead of answering in private and letting the thread die, here they are — answered in…
Every October and April, the same thing happens in the building materials halls of the Canton Fair: a wall of nearly identical XPS tile backer boards, and a sales rep at every booth swearing theirs is the strongest on the row. Some of them are right. The problem is that a large share of those…
The backer board behind your tile is the layer that decides whether a shower stays dry or fails where nobody can see it. This guide compares traditional cement and fiber-cement board with XPS waterproof backer board on the things that matter—waterproofing, weight, dust, mold, strength, installed cost and code—so homeowners, tile setters and builders can…
XPS backer board thickness guide: 12 mm covers most showers on 300 mm studs. 6 mm only over solid backing. 20 mm for wider studs and uneven walls.
XPS tile backer board beats cement board in wet rooms: lighter, fully waterproof, no membrane needed. Factory-side comparison of weight, install speed and cost.
