About Amdry Insulated Subflooring

Amdry is a Do It Yourself (DIY) all-in-one insulated subflooring system with a moisture barrier designed to be installed over existing concrete slabs. The combination of the moisture resistant protective High Impact Polystyrene (HIPS) film with raised drainage channels protects the floor assemblies above by allowing trapped moisture to dry over time thereby creating a healthy, comfortable and warm basement floor.

The Amdry subfloor is compatible with virtually any screw down, nail down or floating finish floor. Amdry is easy to install, using a unique connector system, reducing slab moisture and temperature fluctuations that may lead to mold and mildew problems.

Amdry Insulated Subfloor Panel

Amdry is available in two configurations, an interlocking OSB with a connector system, and a tile version designed for areas susceptible to high moisture or the need for tile floor finish. Both versions provide a continuous thermal break across the entire concrete floor surface while allowing moisture and air to move freely over the concrete thereby creating a warmer floor surface, a drier and more comfortable space to live in.

Amdry Applications

Why Use Amdry?

Creating a Comfortable Space

The insulation layer acts as a thermal separator reducing heat loss through the floor thus creating a warm surface and increasing the thermal comfort of the home owners.

Improved Energy Efficiency

The panels are available in R5, R7, R9 and R11, increasing the overall R-value of your home, reducing heat loss and lowering utility bills.

Quick and Easy Installation

Subfloor panels are installed quickly and easily using a unique and flexible connector system. The 100% recycled polypropylene connectors lock panels effortlessly together, without the need for nails or glue, significantly speeding up the installations process.

The large panels, 2’x4’ (0.61m x 1.22m) provide a full 8 ft2 (0.74m2) surface coverage unlike other products on the market which come in a tile size format.

The larger panels can accommodate minor irregularities and slopes often found in concrete slabs reducing or eliminating the need for shims and/or spacers.
50% less joints speed up installation and improves surface integrity.

Larger boards reduce cutting time of both the boards and connectors and translate into 40% savings on installation time.

Durable Floor System

The Amdry connectors are inserted into the edge grooves of each panel and use a flexible barb fastener to allow for easy insertion and yet provide unparalleled long term holding power. The system is engineered to provide a secure and tight connection for years to come.

These unique connectors eliminate all the issues commonly associated with wooden tongue-and-groove joints; squeaking floors, broken, damaged or chipped tongues and grooves, often damaged from before, during or after installation.

The hollow core of the connectors allows for expansion of the entire floor assembly that naturally occurs when dry wood is introduced to high humidity areas. This built-in compression joint virtually eliminates any chance of buckling or heaving of the floor surface due to excessive expansion.

Superior Moisture Control

By decoupling the finished floor from the concrete, moisture sensitive finished flooring such as engineered hardwood, laminate or carpet remain in a dry environment virtually eliminating the potential for mold and mildew growth.

The bonded surface film on the underside of the foam protects the EPS insulation and the OSB from absorbing moisture that could originate from the concrete slab.

The combination of the surface channels with the moisture resistant protective film allows Amdry to provide continuous air flow over the existing concrete slab, allowing for any trapped moisture to evaporate over time.

A Message from Mike Holmes

I’ve been a contractor for over 30 years, and I’ve seen the damage when the wrong products and materials are used. That’s why I partnered with Amvic — so homeowners know what products help protect their home.
