Ventgrid Is a Durable and Affordable Solution for Interiors and Exteriors

Ventgrid is a high quality affordable and durable product for interior and exterior use. By installing Ventgrid rainscreen under interior floor finishes over concrete slabs, you can increase the drying effect created by enhanced ventilation and significantly reduce the possibility of dangerous mold formation. Similarly, Ventgrid is ideal for creating an effective rainscreen system behind wall cladding and beneath wood roofing.


With over 8000 lbs/ft²(380kpa) vertical load capacity and a unique open grid format, Ventgrid12™, created in Chester, Nova Scotia, Canada, is an extremely versatile product.

It is the perfect air-gap solution for many interior and exterior applications such as:

Subfloors over concrete slabs
Cedar roof shakes and shingles
Exterior wall rain screen assembly
Pavers on flat roofs
And more!

Ventgrid12™ is an important innovation for the building construction industry. It is the ideal solution for assemblies where a drainage/ventilation air space is needed. Unlike ordinary methods such as wood furring, Ventgrid12™ is made almost completely from “post-consumer” recycled plastic so it is highly resistant to deterioration and degradation. Ventgrid12™ will not decay, rot, absorb moisture or support mold growth.

Ventgrid12™ utilizes a unique manufacturing process to produce an incredibly strong and lightweight rigid flat 4’(1.22m)x8’(2.44m) panel with 1/4”(6.4mm) long stand-off dimples for an overall thickness of 1/2”(12.7 mm). The specially engineered plastic is easily snipped with standard hand shears such as sheet metal cutters or scored with a sharp edge and snapped. Because each sheet weighs only 8 lbs(3.6kg), Ventgrid12™ is very easy to handle, saving time and labour. Each sheet quickly covers 32 sq. ft.(2.97m²) of surface area, and the convenient pre-formed fastener holes make the installation fast and simple.

Ventgrid12™ is a high-value building product that is synonymous with high-quality building construction.

Ventgrid12™ for Interiors

Concrete in contact with the ground will always be cold and damp on the surface. Trapped moisture can build up and cause mold and rot. The right solution is to raise the flooring off the concrete for warmth while creating a well-ventilated air space to allow moisture to escape.

Ventgrid12™ for Interiors
Lightweight, fast and easy to install
Low height profile – only ½”
Superior load capacity - will not compress or crush
Easy to cut – just score and snap, no power tools required
Install laminate flooring directly on Ventgrid
Pre-formed fastener holes
Non-absorbent - rot and mold resistant
100% “Post-consumer/industrial” recycled plastic, reusable, recyclable

Ventgrid12™ for Exteriors

Exterior wall and roofing systems should incorporate Ventgrid12™ to provide a proper air space, ensuring water can escape instead of collecting behind the cladding. This helps prevent water damage and mold/mildew formation.

Save time, save money. Better builders use Ventgrid for:

Ventgrid12™ for Exteriors

Fast and easy installation:

Covers 32 ft² per sheet – greater wall coverage in less time
Lightweight for easy handling – less than 9 pounds each
Minimal fasteners required – save time and labour costs
Easy to cut – just score and snap, no power tools
Open grid – easier to find the stud

Performance and value:

Cannot crush – consistent cladding nail penetration
Superior ventilation – no moisture build-up
Non-organic – won’t rot or mold
Unaffected by cold – even in winter conditions
Protects building paper – reduces wind damage
Fully supports cladding – reduces mechanical damage
Recycled plastic – great for LEED projects


While creating an air gap behind cladding is important, it also presents another challenge; bugs, bats, rodents, and other pests can find the space behind the cladding to be a particularly inviting nesting place which is why Ventrim10™ was developed. Ventrim10™ is used at the top and bottom of the wall to neatly close off the void behind the cladding preventing a pest invasion while still providing ventilation. Made of tough PVC, Ventrim10™ is a perfect way to cap the gap.


Most cladding companies now either require or strongly recommend a ventilated air space between the cladding and sheathing paper. This is referred to as rainscreen exterior wall assembly. The challenge, however, is how to close off the top and bottom of the air space for pests such as flying insects, bats, rodents and other undesirable home invaders.


The answer is a simple product called Ventrim10™.


Ventrim10™ was designed to work as an integral part of a system along with Ventgrid12™. It is made of durable and long-lasting PVC with vent holes punched in the bottom of the trough for drainage and ventilation. Ventrim10™ has been designed to be easy to work with; it is lightweight, easy to cut and nail through. Produced in consistently straight 8’(2.4m) lengths, it is a great way to level the starter course of cladding too.

Get Optimal Drainage With Ventgrid12™

Made from post-consumer recycled plastic, Ventgrid12™ can provide the desired air space for drainage and other uses on both the interiors and exteriors of your building system.
