How should you choose a subfloor soundproofing product?

There are many subfloor products on the market. To make an informed choice combining performance and durability, it is essential to know what to consider.

The subfloor membrane must act as a vapour barrier, since the wood reacts to moisture. To maintain its acoustic performance, the subfloor membrane must be resilient, which means it must remain stable without sagging over time.
In addition to these two essential elements, several other criteria must be considered and compared to choose the right product:

  • The installation method
  • Its compatibility with complementary products (e.g. adhesive and mortar)
  • Product knowledge of installers
  • Membrane thickness
  • Compliance with various programs (e.g. LEED and Novoclimat)
  • Results of various acoustic tests (e.g. FIIC, FSTC and Robinson)
  • The anti-fracture characteristics (for a membrane applied to ceramic)
  • Etc.

How to interpret the results of FIIC and FSTC indexes?

FIIC normalized impact noise insulation index: This index consists in testing the transmission coefficient of impact noises (e.g. footsteps, falling objects, and knocks).

FSTC sound transmission index: This index measures the transmission of airborne noises (e.g. voice, television, and music).

In both cases, the higher the number, the better the noise reduction. Both indexes are not necessarily related; that is to say a good FIIC does not necessarily mean a good FSTC, and vice versa. However, since impact noise becomes airborne noise a fraction of a second after the impact, it is clear that a good FIIC index promotes a better FSTC index.


How long does an asphalt protector last?

An asphalt protector can last between 1 and 7 years depending on the product used. It provides protection against cracks and deterioration caused by wear, frost, oil spills, gas, salt, sun and rain.

What are performance indexes?

Acoustic performance of a system is defined by two indexes: the IIC (Impact Insulation Class) for impact noise and STC (Sound Transmission Class) for airborne noise. To get even closer to the real conditions, we can test acoustic performance indexes on construction sites. In this case, the indexes presented are preceded by the letter F to denote the concept of construction site (Field). It is important to note that the FSTC and FIIC results are generally lower than the STC and IIC results since control is lower on a real construction site than during laboratory tests. However, they are closer to reality.

Which products should be used to repair asphalt cracks?

It depends on the crack size.

What is the difference between sound absorption and sound insulation?

Sound absorption of a wall consists of preventing the sound from switching from one side of the wall to the other side without creating reverberation. The objective is to minimize the sound perceived from the opposite side of the source without amplifying noise perceived inside the emitting room by reverberation phenomenon.

Acoustic insulation of a wall consists of preventing the sound from passing from one side of the wall to the other side. Therefore, the objective is to minimize the sound perceived on the opposite side from the source of noise.

What is the difference between sound and noise?

First of all, sound is an acoustic vibration that propagates in the air and causes an auditory sensation. A sound is mainly defined by two parameters – the frequency (or pitch) and the volume (or intensity).

The intensity refers to the force of the sound. Sound intensity is measured in decibels (dB). It can range from 0 dB to 194 dB. A sound that reaches the maximum intensity of 194 dB can certainly affect your sense of hearing.

Verbal discussion: between 45 and 55 dB
Background noise in a room: about 28 dB
Phone ringtone: about 80 dB
Vacuum cleaner: between 60 and 85 dB
Television: about 70 dB
The frequency refers to the tone of the sound. Frequency is measured in hertz (Hz). Human beings can perceive frequencies between 20 Hz and 18,000 Hz, and animals perceive frequencies beyond what humans can hear.
Noise, for its part, is a set of sounds produced by irregular, unharmonious vibrations. It is often perceived as a nuisance.

What is the difference between airborne noise and impact noise?

In the field of building acoustics, two types of sound transmission exist.
Airborne noise: Airborne noises are transmitted by air and atmosphere. The radio, or people carrying on a conversation, are good examples of airborne noises.
Impact noise: Impact noises propagate through solids and result from a shock on them. The footsteps of a person and the sound of an object falling on the floor are examples of impact noises.

Which product helps to restore and protect metal roofing from corrosion?

The RESISTO ANTICORROSION SEALANT is a thick, homogeneous waterproofing coating made of elastomeric bitumen, volatile solvents and reflective aluminum pigments. It restores and protects metal surfaces, such as metal roofs, sidings, storage tanks, and water ducts from corrosion. The aluminum pigments protect the sealant and the coated surface from UV radiation and offer an attractive appearance.

Which product helps to ensure air/vapor barrier waterproofing of exterior surfaces (doors and windows)?

RED ZONE AIR BARRIER AND WATERPROOFING MEMBRANE is mostly used as an air/vapor barrier for door and window frames. It provides continuous air and vapor protection, eliminates drafts and water leaks, is self-sealing around nails and screws to ensure waterproofing, is UV resistant (must be covered within 90 days), and is clean and easy to install and requires no special tools.

What are building acoustics?

Nowadays, noise is a major source of pollution. Since noise in a building can easily travel through air, materials, openings and structures, soundproofing is an essential element to be considered early, at the design phase of the building.

What are the differences between a reflective insulation system and a radiant barrier?

Reflective insulation is thermal insulation composed of enclosed air spaces sandwiched between one or more low-emittance materials. A radiant barrier system consists of a reflective material facing an open air space. The main difference between the two is that a reflective insulation system has a measurable R-value (source: RIMA).

By definition, this means that our AYR-FOIL bubble products are reflective insulation systems because they already have an enclosed air space sandwiched between the outer layers. Radiant barriers are typically products, such as aluminum-aluminum or aluminum-kraft paper. These products can also be reflective insulation systems if their foil side is facing an enclosed air space.


In most applications, it is recommended to seal seams with an appropriate tape. AYR-FOIL TAPE (vinyl, metalized, aluminum) meets fire ratings and vapor barrier requirements. The glue is designed to adhere permanently to foil and white polyethylene.

Why is it recommended to install a protective membrane on exterior floor joists (patios and balconies)?

The installation of a protective membrane as RESISTO JOIST GUARD prevents the rotting of structural timber under exterior floors and substantially extends the service life of the patio at low cost.

Where should you use AYR-FOIL insulation?

Your imagination is almost the only limitation to the many uses of AYR-FOIL. It can be installed wherever you would use any other insulation. It can also be used for other applications, such as a camping mattress, stadium seat, cooler insulation or windshield screen.

Is concrete a good sound insulator?

Concrete is an excellent acoustic insulator from airborne noises. However, since concrete is a very hard material, it reduces the acoustic performance in terms of impact noises, which it conducts.

When designing a building, the selection of a structure with or without concrete should be considered. In the case of a building with five or more floors, there is no choice because the National Building Code requires a structural concrete slab. It is recommended that you use soundproofing products specifically designed to increase acoustic performance by reducing impact noises.

Is there a product you can use to flash and protect the joints between the sill and the jamb, which are often the most critical areas?

YES, RED ZONE CORNER GUARD saves time and helps reduce costly cutting, folding, and caulking mistakes when waterproofing complex details.

Is AYR-FOIL a vapor barrier?

YES. All our bubble products are ASTM E96-compliant type 1 vapor barriers. Like any other vapor barrier, AYR-FOIL has to be installed in the right place in your assembly. Perforated aluminum-aluminum and aluminum-kraft paper radiant barriers are available when a vapor barrier is not desired.

Does AYR-FOIL work in warm and cold climates?

YES. Whether you live in a warm or cold climate, the three methods of heat transfer (conduction, convention and radiation) apply. AYR-FOIL will radiate out warm air in the summer and keep it in during the winter.

Does an acoustic membrane have a specific acoustic index?

NO. The index is determined by measuring a complete assembly in which the membrane is used. No regulation requires manufacturers to explain how they achieved their acoustic performance results. However, always ask for the full details of the floor/ceiling assembly associated with acoustic indexes presented, in order to be able to compare them to your actual project.
