8mm Waterproof Polyethylene Foam Sheet Xpe Xlpe Insulation For Roof
Sound Proof
8mm waterproof polyethylene foam sheet, available in XPE
(Cross-linked Polyethylene) and XLPE (Cross-linked Low-density
Polyethylene) variants, is an ideal solution for roof insulation
and soundproofing. Crafted via advanced cross-linking technology,
it features a closed-cell structure that effectively blocks water
penetration while reducing heat transfer and noise transmission.
Key Features:
Waterproof & Moisture-resistant: Provides reliable protection
against leaks and humidity.
Thermal Insulation: Low thermal conductivity ensures excellent heat
retention or dissipation, optimizing energy efficiency.
Sound Absorption: Reduces airborne and impact noise, creating a
quieter indoor environment.
Lightweight & Flexible: Easy to cut, install, and conform to
irregular roof surfaces.
Durable & Eco-friendly: Resistant to aging, chemicals, and UV rays,
with no harmful substances released.
Suitable for residential, commercial, and industrial roofs, this
foam sheet enhances comfort while extending roof lifespan. Its
versatility makes it a cost-effective choice for both new
constructions and retrofits.

FAQ:
Q1:Is XLPE foam recyclable?
Due to it is crosslinked and close cell, it is hard to recyclable.
But the wasted pe foam could be reused again, like to be remade
to be mattress, underlay, furniture filling etc
Q2:Does your foam work with adhesives?
Our foam does work well with adhesives. PE foam tape is one of the
foam application
Q3:Can you do custom design?
Of course,Color,Logo,Size,Pattern and Materials all could be
customized, we have the professional technical staffs.
Q4:What is the difference between polyethylene and polyurethane
foam?
Polyethylene is a firm, closed-cell foam.It is also sometimes used
as a top layer over softer foam in order to provide better footing
while the lower, softer foam adds some shock absorption. What is
polyurethane foam? Polyurethane is a softer, open-cell type of foam
that is made in varying degrees of firmness.
