TC-417-GP Thermal and Acoustic Solutions Technical Support Specifications Guide Model 3-Part Specification 1. Related Works and Sections 1.1.1 Section 07210 - Building Insulation Section 09820 - Acoustic insulation 1.2 Work Included 1.2.1 Provide all materials, labour, equipment and services necessary for, and incidental to, the complete and correct installation of all spray applied insulation and related work as shown on the drawings or where specified herein, and in accordance with all applicable requirements of the Contract documents. 1.2.2 The spray applied insulation and installation shall conform to the applicable building and/or other code requirements of all authorities having jurisdiction. 1.3 Quality Assurance 1.3.1 If requested, provide samples of minimum size 300 x 300mm (12" x 12") of spray applied insulation on a rigid backing appropriate to the installation. 1.3.2 Work shall be performed by a firm with expertise in the sprayed insulation and/or fireproofing business. The firm shall be licensed or otherwise approved by the insulation material manufacturer. 1.3.3 Before proceeding with the application of the spray applied insulation, approval of the proposed material thickness shall be obtained from the architect and other applicable authorities. 1.4 Manufacturer's Literature 1.4.1 Copies of the manufacturer's literature, clearly indicating conditions of acceptance and method of application, shall be available on site before and during period of performance of related work and product installation. 1.5 Material Delivery and Storage 1.5.1 All material to be delivered to the site in original, undamaged and unopened packages clearly labelled by the manufacturer. 1.5.2 All materials to be stored on site in a warm, dry location on either a concrete floor or raised platform. Material must not get damp or wet. 1.5.3 Adhesive concentrate must not freeze. 1.6 Project Conditions 1.6.1 Spray applied insulation shall only be installed under the conditions as stated in the manufacturer's published application instructions. 1.6.2 When the prevailing outdoor temperature at the site is less than 4 0C (400 F), a minimum substrate and ambient temperature of 4 0C (400 F) shall be maintained for 24h before, during and until the applied product is completely cured (dry) through to the substrate. If necessary for job progress, the General Contractor shall provide enclosures with dry heat to maintain temperature. 1.6.3 General Contractor shall provide ventilation to allow proper drying of the installed spray applied insulation during and after its application. 1.6.4 At all times during installation and drying of spray applied insulation ventilation in enclosed areas shall not be less that 3 complete air changes per hour. 1.6.5 All patching and repairing of installed spray applied insulation required because of damage or cutting by other trades shall be performed under this Section and paid for by the trade(s) responsible. 1.6.6 The General Contractor shall allow the Manufacturer's representative full access to the site during normal working hours. 1.6.7 The Contractor shall co-operate in the co-ordination and scheduling of the insulation work to avoid delays in job progress. 2. Products 2.1.1 Materials: Spray applied insulation shall be TC-417 GP white glass fibre together with its specified synthetic emulsion adhesive and shall conform to test protocols and results as detailed in 2.1.2 below. 2.1.2 Spray applied insulation shall not contain free crystalline silica, asbestos or combustible fibre, and shall be applied to conform to the drawings, specifications and following test criteria: ASTM C-518: R = 4.17/in; RSI = 29.32/m K = 0.24; ( = 0.0346 ASTM E-136 / CAN/ULC S114: Non-combustible ASTM E-84 / CAN/ULC S102: Flame spread 25; Smoke development 50 ASTM C-423 99a: NRC = 1.00 (50mm/2 in.) ISO 354: NRC = 0.95 (50mm/2 in.) 2.1.3 Spray applied insulation shall be WH certified. 2.1.4 Adhesive shall be mixed with fresh, clean, potable water in the exact proportion as recommended by the manufacturer. 2.1.5 Adhesive must be kept from freezing at all times. 3.1 Preparation 3.1.1 All surfaces to receive spray Insulation shall be free of all petroleum-based greases and oils, loose mill scale, rust, poorly adhered paint and other foreign materials that could impair bonding to the surface. Any required cleaning of the substrate to receive the material shall be the responsibility of the General Contractor. 3.1.2 Remove dust, dirt or foreign material on surfaces to which the product is to be applied, that could otherwise create a false bond or surface staining of the product. 3.1.3 Verify compatibility and bond requirements of all surfaces to receive spray applied insulation. 3.1.4 Ensure that all equipment, piping, ducts or other units that would interfere with the application of spray applied insulation are not positioned until application is complete. 3.1.5 Ensure that proper temperature and ventilation are maintained as specified in 1.6.2 through 1.6.4. 3.1.6 Provide and install masking, drop cloths or other suitable coverings to prevent overspray from coming into contact with unintended fixtures and surfaces. 3.2 Application 3.2.1 Mix and apply spray applied insulation in strict accordance with manufacturer's published recommendations. 3.2.2 Apply product in sufficient thickness to achieve the required thermal and/or acoustic value. 3.2.3 Use a 'one-pass' application procedure. Do not layer application. 3.3 Clean-up 3.3.1 Remove overspray from equipment and surfaces not intended to be covered. Perform all removal work while installed product is still wet. 3.3.2 Ensure clean up is up to industry standards. 3.4 Options 3.4.1 The surface of the spray applied insulation can be left untamped for basic finish, or can be board tamped and oversprayed for a flatter, more uniform finish. 3.4.2 For a more durable and attractive finish in exposed areas, it is recommended that the surface be board tamped and oversprayed with adhesive. NOTE: Any installation tamped by any means must retain adequate thickness to meet the specified thermal and/or acoustic value. 3.4.3 If a finish colour other than white is desired we suggest: a) For dark grey or light grey use manufacturer's colour additives for adhesive (if available); b) Topcoat with a spray applied insulation surface protection coating (if available from the manufacturer). This coating can be coloured as desired and has the added benefit of improving surface cohesion of the installed material; c) Paint the installed spray applied insulation with any good quality paint of the desired colour.
