Insulation

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 airspace. 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 high performance reflective insulation products are reflective insulation systems because they already have an enclosed airspace sandwiched between the outer layers. With regard to radiant barriers, there is a product called REFLECTIVE VAPOR BARRIER composed of a black polyethylene film and a metallized surface. This product can also be used in reflective insulation systems if the foil side is facing an enclosed airspace.
Yes. All our bubble products are ASTM E96-compliant Type 1 vapour barriers. Like any other vapour barrier, it has to be installed in the right place in your assembly.
Your imagination is almost the only limitation to the many uses of use RESISTO high performance reflective insulation. 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.
In most applications, it is recommended to seal seams with an appropriate tape. RESISTO ADHESIVE TAPES (vinyl, metallized, or aluminum) meets fire ratings and vapour barrier requirements. The glue is designed to adhere permanently to foil and white polyethylene.
Yes. Whether you live in a warm or cold climate, the three methods of heat transfer (conduction, convection and radiation) apply. It will radiate out warm air in the summer and keep it in during the winter.

Protection of asphalt surfaces

An asphalt protector can last between two and six years depending on the product used. It provides protection against cracks and deterioration caused by wear, frost, oil spills, gas, road salt, sun, and rain. Two years: ASPHALT DRIVEWAY SEALER Four years: ASPHALT DRIVEWAY SEALER Six years: ACRYLIC ASPHALT RESTORER

Soundproofing

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 will 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, inharmonious vibrations. It is often perceived as a nuisance.
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.
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.
Sound absorption of a wall consists of preventing the sound from switching from one side of the wall to the other 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. Therefore, the objective is to minimize the sound perceived on the opposite side from the source of noise.
The acoustic performance of a system is defined by two indexes: the IIC (Impact Insulation Class) for impact noise and the 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.
The FIIC normalized impact noise insulation index consists of testing the transmission coefficient of impact noises (e.g., footsteps, falling objects, and knocks). The FSTC sound transmission 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.
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:
  • Installation method
  • 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)
  • Anti-fracture characteristics (for a membrane applied to ceramic)
  • Etc.

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 or ceiling assembly associated with acoustic indexes presented, in order to be able to compare them to your actual project.
Concrete is an excellent insulation from airborne noises. Since concrete is a very hard material, it reduces acoustic performance in terms of impact noises, since concrete conducts noises. 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.
