1. Walls Above and Below Grade The first step is to cut or pierce a point of entry for the hose approximately 305 mm 12 to 406 mm 16 inches from the top of the cavity The hose can then be lowered into the cavity such that the end of the hose sits 152 mm 6 to 305 mm 127 inches off the bottom of the cavity The machine can then be started and insulation injected into the cavity 9 0 As the cavity fills insulation material will pack around the nozzle until excessive back pressure causes the hose to back up Once this occurs the hose should be immediately withdrawn up the cavity approximately 305 mm 12 such that the hose unblocks and the next section of the cavity begins to fill with insulation The process of raising the hose and allowing it to back up in successive stages is repeated until the portion of the cavity below the hose entrance is completely filled with insulation The por tion of the cavity above the hose entrance is filled by quickly inverting the nozzle and filling the remainder of the cavity with insulation until the hose backs up Sloped or Cathedral Ceilings The installation procedure for ceilings is the same as wall procedure except that cavities longer than 3 metres 10 feet must be blown in stages This is due to the fact that it is difficult to lower the hose more than 3 metres down the cavity without having the hose bunch and it is more dif ficult to control hose direction When filling cavities2. im Nu 3 dee el i N installation Manual EnviroShield Wall System Insulation Enviroshield is ia dense pack cellulose insulation system that is ntended for application in walls Cellulose insulation ceilings and floors behind mesh or poly utilizing provides seamless Weathershield or ProCell Green insulation coverage Cellulose insulation is not only a natural choice for the environmentally conscious consumer but one that outperforms both thermally and acoustically With a superior R value of 3 8 per inch EnviroShield provides excellent cover age perfect fit and greater density and is a sound alternative to other fibrous insulations Our insulation delivers long term fire retardant protection and unlike other insulation products will not melt or propagate fire Safe and easy to install it does not itch or contain any formaldehyde or harmful emissions It is specially Superior thermal treated to repel insects and rodents and will not promote the growth of harmful and acoustical mold and fungi properties comfort With over 87 recycled content and many performance benefits cellulose is a natural choice for all your insulation needs Start saving today save on product cost and get immediate rewards in energy savings Contact us today for more iinformation EnviroShield is available coast to coast Walls EnviroShie

Using channels or furring fasten the poly to the face of each framing member Placement and fastening of furring may be done on either 400 mm 16 spacing for 19 mm x 64 mm 1 x3 furring or 600 mm 24 spacing for 19 mm x 89 mm 1 x4 furring Furring must be fastened to the framing with not less than 51 mm 2 nails Placement and fastening of resilient channels should be done on 400 mm 16 spacing and fastened to the framing with not less than 51 mm 2 nails For more details please consult your local building office Once the furring has been applied the vapour barrier can be further secured to the face of each stud using 13 mm 2 staples spaced every 76 mm 3 to 102 mm 4 apart If required an additional RSI 0 5 R 2 8 can be obtained on stud walls to achieve a total rating of RSI 4 0 R 22 8 if the vapour barrier is loosely applied to the assembly and not fastened to the face of each stud This will allow the insulation to bulge up between the channels or furring and onto the stud faces thereby increasing the effective insulation depth to 19 mm 3 4 In this ap plications the film should be initially hung to the top of the wall section through the use of 13 mm 2 staples spaced every 150 mm 67 to 300 mm 12 apart Once secured the barrier should then be loosely draped and stapled to the bottom plate of the wall such that there are no folds or wrinkles in the film Strapping can then be applied by working from the
6. The installer shall also ensure that the cavities are prepared in accordance with this manual and that the machine is in good working order and set to the predetermined calibration settings Density Verification The installer should verify material density at the beginning during and at the end of each job A density check can be performed using one of two following methods The first method suitable for both wall and ceiling applications requires the installer to keep track of the number of bags of insulation blown for a specific area By dividing the total area blown by the bags of insulation used the coverage bag can be determined By comparing this value to the appropriate value given in Table 1 of Appendix A the installer can determine how close he or she is to the target density of 48 kg m or 40 5 kg m 3 0 Ib ft 2 5 Ib ft The second method designed specifically for wall applications requires the installer to keep track of the number of bags used and the number of cavities blown By dividing the number of cavities blown by the appropriate cavity bag value given in Table 2 of Appendix A the installer can determine the number of bags required By comparing this value to the actual number of bags used the installer can determine whether the cavities are being under or over blown If the actual value is less than the design theoretical value then the equipment should be ad justed By increasing the amount of air and or reducing

8. behind vapour barrier remember to blow sufficient material around the hose entrance approx 300 to 600 mm 1 2 ft prior to blowing the next stage This will prevent insu lation from spilling out of the pierced membrane when the next stage 15 blown In open web truss systems it should be noted that the hose must be inserted and lowered along the side of the cavity closest to the previously insulated cavity This will prevent excessive mate rial from spilling into the adjacent uninsulated cavity and thus reduce the potential problem of trying to lower the hose down an obstructed cavity If insulation does spill into the adjacent cav ity prior to blowing the hose should be forced as deeply as possible into the material This will help ensure the insulation in this area is adequately packed In cases where it is not possible to adequately force the hose into the material or the material does not get adequately packed upon filling another hole should be made in the middle of the soft area and additional insulation blown in Post Installation Procedures Upon completion of the job the installer should perform a visual inspection to ensure all cavities have been filled and are firm to the touch The installer should then determine if the correct num ber of bags where installed If the actual number of bags 15 less than the calculated the installer should then establish which cavities are softer than the others and top up those cavities This can be
9. done by piercing a hole in the soft area physically compressing the material by hand inserting the hose and filling the created void A quick hammer test can also be performed on any suspect cavities This is done by hitting the studs rafters or trusses of randomly selected cavities with a heavy hammer a number of times The material the cavity should not slip move any way if the correct amount of insulation has been installed If the material within the cavity moves then additional insulation should be packed into the cavity Once the installer is satisfied with the outcome of the job the wall cavities exhibiting excessive bulge i e greater than 13 mm 2 can be rolled Do not push the roller below the face of the framing members Over compression of the material in the cavity may result in separation and 10 0 10 1 10 2 10 3 10 4 or settlement problems slight bulge is always desirable in order to ensure continuous contact of the insulation with the drywall For vapour barrier systems once the cavities have passed inspection the pierced poly should be repaired and sealed with sheathing tape or using caulking and a strip of 6 mil polyethylene vapour barrier Quality Control Pre Inspection The installer is responsible for ensuring all fire codes are adhered to as it re lates to insulating around recessed light fixtures not approved for insulation contact chimneys flue or other heat emitting devices
