PRODUCT DESCRIPTION:

• TC-4I7 GP is a glass fibre based spray-applied thermal and acoustic insulation;
• Its major uses are within the multi-unit residential, institutional, commercial and industrial markets for installation in both new construction and retrofit applications.

• TC-417 GP is comprised of pure white, inorganic, non-combustible glass fibres (25% recycled glass) and a non-hazardous, water-based synthetic emulsion adhesive;
• These components are combined during application on the job site.

• When installed, TC-417 GP produces a monolithic, non-combustible insulation blanket that resists heat flow, air circulation and moisture migration to the substrate;
• TC-417 GP is equally effective in retarding heat flow into or out of the structure as required.
• TC-417 GP can be applied to most sound, grease and oil-free substrates such as concrete, steel, gypsum board, wood and rigid insulation;
• It also adheres to spray-applied fire resistive materials;
• The single-step, spray-applied process allows the most complex surface configurations to be covered easily and efficiently with no seams or voids;
• TC-417 GP can be left exposed as a heavily textured surface or it can be covered, depending on the design and type of application.

• Non-combustibility:

 

CAN/ULC S114	Non-combustible
ASTM E-136	Non-combustible

• Surface burning characteristics:

 

CAN/ULC S102	Flame spread = 5	Smoke developed = 10
ASTM E-84	Flame spread = 5	Smoke developed = 10

Non-Combustibility versus Flame Spread:

There seems to be some confusion in the industry concerning the accepted definition of non-combustibility as compared to low flame spread. The distinction is quite simple:

• An organic substance such as paper can be treated with flame retardant material that ensures that it will burn slowly, and can then be considered to have a low flame spread;
• An organic material, even when treated with fire retardant and rated as 'low flame spread,' can never be rated as non-combustible because its flaming time, temperature rise and mass loss are more than allowed when subjected to industry-accepted test procedures;
• Only inorganic materials, or mixtures containing a very small organic component, can be rated non-combustible according to industry standards — e.g. — ASTM E-136, CAN/ULC S114.

Note: Unlike spray applied organic insulation materials, that can only qualify for low flame spread ratings, the low flame spread and non-combustible ratings of TC-417 GP are permanent. Therefore, it does not require either initial addition of a fire retardant at time of application or periodic top up of with fire retardant to maintain its ratings.

CONDENSATION CONTROL

The following information on condensation control refers primarily to thermal installations where there is a deliberate effort to eliminate condensation in the building. However, there are some circumstances in which a thermal or acoustic installation may inadvertently cause condensation to form in the installed product.

This situation can occur in cold or cool temperate climates when the following circumstances are encountered:

• Freezing temperatures occur at some time during the year;
• The roof is steel or other impervious material that functions as a vapour barrier;
• The roof is pitched, rounded, or otherwise configured so that a dead air space can exist at the highest point(s);
• There is inadequate, or no, insulation on the outer surface of the roof;
• The attic space is poorly ventilated and allows dead air to collect at the high point(s) of the roof;
• The building is heated.

As long as no more than 33% of the total insulation value of the roof assembly is on the warm side of the vapour barrier, no condensation will form in the insulation.

Example:

• There is rigid board insulation with an R value of 12 (RSI 2.1) on the outside (cold side) of a steel roof;
• Insulation to an R value of 6 (RSI 1.05) can be safely added to the underside (warm side) of the roof assembly.
• The resultant total of R18 (RSI 3.15) represents a 50% increase in the thermal resistance of the roof insulation and represents a worthwhile addition to the assembly.

TC-417 GP helps control condensation under many different circumstances in both conditioned and unconditioned buildings:

• In unconditioned buildings subject to condensation forming on the inside of the walls and roof, installation of the product will eliminate the problem;
• In conditioned buildings TC-417 GP helps to control condensation because it forms a monolithic blanket and eliminates voids at the substrate. Unavoidable gaps between batts and/or rigid panel insulation sheets and voids at the substrate allow convection currents to develop and condensation to form.
