11 Client Report A Construction Acoustics Laboratory Analysis The objective of this testing series was to obtain a set of floors with good airborne sound insulation rating (STC +) and good impact sound insulation rating (IIC +). A test matrix of CLT and glulam floors with various precast and dry toppings was established. This brief analysis section compares the 1/3-octave airborne transmission loss (TL) and normalized impact sound pressure levels (NISPL), as well as the single number ratings (STC and IIC) to identify toppings and coverings that perform the best on CLT and glulam floor assemblies. Bare CLT vs. bare glulam Graph 1: Airborne TL 100 Graph 2: Light Impact NISPL Airborne Sound Transmission Loss, TL, in db Normalized Impact Sound Pressure Levels, NISPL, in db Frequency, f, in Hz Frequency, f, in Hz Legend Specimen Number STC IIC 1 CLT131 A F GLAM89 A F The TL and the NISPL of the bare 131 mm CLT and the bare 89 mm glulam floor assemblies are compared in Graph 1 and 2. The blue curves in the above graphs show that the CLT outperforms the glulam bare floor assembly. Looking at the legend below the graphs, the CLT floor is 4 STC points and 2 IIC points better than the glulam floor. The higher STC and IIC rating of the CLT floor correspond to the increase in the bare floor thickness and consequently a greater area density and stiffness. Page 9 of 101

In the above graphs, there are three pairs of curves which correspond to the pair of CLT and glulam floors with no topping, with the precast concrete topping and with the OSB raft. There are slight differences in the individual TL and NISPL curves of the CLT and the glulam with the same topping. The TL curves of the CLT base floor (aqua, green and blue) are above those with a glulam base floor (orange, purple and red respectively). The STC and IIC ratings of the CLT and glulam floors with the same topping (heavy and/or decoupled) achieve similar values (±1 STC or IIC) as seen in the legend below the graphs. Although the TL and NISPL curves of both type of floors with the same toppings follow the same trend, they are not superimposed. The single number ratings (STC and IIC) of both floor types with the same topping indicate that the rated overall performance is similar (±1 STC or IIC). Page 10 of 101

TL curves of the CLT floors with a concrete precast topping on a resilient membrane (blue, green and red) are higher that the curves of the CLT floors with dry panelized toppings (purple and aqua). The difference in TL between the different precast concrete thicknesses (blue vs red) or the type of interlayer (red vs green) is not significant. For the NISPL curves, the floors with the precast concrete topping (blue, green and red) are better than those with the dry panelized toppings (purple and aqua). In terms of IIC rating, as shown in the legend below the graph, the best floor assembly is the one with the 38 mm precast concrete on the SonusWave 25 mm rubber mat with IIC 49. The mass of precast concrete toppings of 38 mm (98.6 kg/m 2 ) and 70 mm (165.8 kg/m 2 ) outweigh the mass of the SonoDeck (13.5 kg/m 2 ) and that of the Fermacell (26.0 kg/m 2 ). For poured or precast concrete slabs (06F vs. 07F), the increase from the 38 mm to the 70 mm precast is not noticeable for STC rating (STC 56 each) and has a unexpected, possibly unrepeatable, negative effect for the IIC rating (IIC 49 to 46).

Comparing all the TL and NISPL results of the floors tested, the best floor assembly is the one with the OSB raft topping which includes a 38 mm precast concrete topping on top of 17 mm SonusWave (A F the light blue curve) and achieves STC 66 and IIC as shown in the legend below the graph. Removing the sand fill from the best assembly (26F) and substituting it with glass fiber batts (A F) or removing the SonusWave from the best assembly (26F) (A F) achieves lower TL and NISPL results. The installation of the OSB raft is beneficial since it highly decouples the rigid CLT floor. The mass of the sand also increases the area density. Page 12 of 101

The best CLT floor assembly (in purple) with the lowest NISPL curve is composed of a patch of laminate flooring on a 38 mm precast concrete topping on 17 mm SonusWave rubber membrane on top of the OSB raft. The addition of laminate flooring to the bare concrete surfaces improves the NISPL curves; moving from the blue to the red curve, or from the green to the purple curve. The IIC improves by 6 or 4 points respectively for those two set of curves as shown in the legend under the graph. In general, the improvement of IIC ratings due to the addition of coverings will be more noticeable for floors where the IIC ratings are limited at mid to high frequencies and for reference floors that have lower IIC ratings.

16 Construction Acoustics Laboratory Client Report A Other Considerations Varying the thickness of the CLT or glulam floor One CLT floor thickness (131 mm) and one glulam floor thickness (89 mm) were evaluated as part of this floor test series. As seen in Graph 3 and 4, the test results show that CLT or glulam floors with the same topping achieve similar TL and NISPL values as well as STC and IIC ratings (±2). It is expected that an increase in the thickness of the base floor assembly will not degrade the TL or NISPL values. Precast vs. poured concrete toppings As part of this test series, no comparisons were performed for precast vs. poured concrete toppings. In referring to report A and the floor tests reported there, it is expected that STC ratings will remains the same or improve for poured toppings (vs. precast), whereas it is expected that IIC ratings will decrease. The improvement or deterioration of the STC and IIC is strongly dependent on the mass of the topping and the resiliency of the underlayment. Specifications for sand fill For this project, silica sand #71 was used as fill under the OSB raft but any other sand or fill with a density varying between 1400 kg and 1700 kg could be used as a substitute without significant change to IIC and STC ratings. It is important that the sand or fill be dry, remains loose and that only sand types approved to be installed in buildings are used. In-situ vs. laboratory results The laboratory sound insulation results measured according to ASTM E90 and ASTM E492 represent an upper limit of the direct sound insulation that can be measured in-situ. A number of factors influence the in-situ performance, for example: flanking sound transmission, specimen size, specimen coupling and construction workmanship. Page 14 of 101

The results in this report apply only to the specific sample submitted for measurement. No responsibility is assumed for performance of any other specimen. Measurements of normalized impact sound pressure level (NISPL) were conducted following ASTM E492-09, Standard Laboratory Measurement of Impact Sound Transmission through Floor-Ceiling Assemblies Using the Tapping Machine but had a small patch of covering material instead of full surface coverage. In the graph: The solid line is the measured normalized impact sound pressure level (NISPL) for this specimen. The dashed line is the IIC contour fitted to the measured values according to ASTM E The dotted line is the background sound level measured in the receiving room during this test (may be below the displayed range). For any frequency where the measured NISPL is less than 10 db above the dotted line, the reported values were adjusted as noted below. Bars at the bottom of the graph show positive differences; where the measured data are greater than the reference contour as defined in ASTM E Shaded cells in the table and areas in the graph are outside the IIC contour range. In the table: Values marked c indicate that the measured background level was between 5 db and 10 db below the combined receiving room level and background level. Values marked * indicate that the measured background level was less than 5 db below the combined receiving room level and background level and the reported values of NISPL provide an estimate of the upper limit of normalized impact sound pressure level, according to the procedure outlined in ASTM E The reported values of NISPL have been corrected according to the procedure outlined in ASTM E Page 97 of 101

100 Construction Acoustics Laboratory Client Report A Client Nordic Engineered Wood 1100 Ave des Canadiens-de-Montreal Montreal QC H3B 2S2 Specimen Specimen ID Small patch of laminate floor on Roberts Soft Stride on 38 mm precast concrete slab on 17 mm SonusWave placed on a OSB wood raft on top of glulam decking (89 mm) A SF Construction Date April 14, 2016 Specimen Description Covering (small patch): 8 mm click laminate flooring was installed on Roberts Soft Stride closed cell foam. The patch covered an approximate area of 4 m 2 in the middle of the floor. Topping: A 38 mm (1-1/2 ) precast concrete slab was placed on 17 mm Regupol SonusWave on top of 18 mm (23/32 ) OSB sheeting. The OSB sheets screwed down with the long side perpendicular to the 38 mm x 64 mm (2x3) wood battens, with the narrow side down, using mm (2 ) long #10 wood screws spaced 1 mm (6 ) o.c. along the edges and 200 mm (8 ) o.c in the field. Wood battens spaced at 610 mm (24 ) o.c. and glued to 10 mm rubber membrane were installed at the bottom. Fill: A 6 mil polyethylene sheet was put down on the CLT and the wood batten and resilient layer were installed directly on top (floating). mm (2 ) of dry silica sand (#71) filled the cavity of the batten leaving a 12 mm (1/2 ) air gap between the OSB and the sand. Glulam Decking: The specimen was composed of 13 glued-laminated timber (glulam) decking panels nominally 384 mm wide x 89 mm thick x 3890 mm long (15 x 3-1/2 x 153 ). The combined panels filled the entire floor opening of the test frame. The glulam decking panels were joined using 90 mm (3-1/2 ) long common nails spaced 0 mm (12 ) on centre along the joints. The glulam decking floor was resting on the lip of the test frame and was not fastened to the test frame. The air gaps between the edges of the glulam decking floor and the test frame were filled with glass fiber insulation and covered with cloth tape. Duct putty was installed around the lower perimeter of the test frame and the glulam.
