It is frequently installed after decontamination to restore the thermal performance of the building. Our technicians install it on the South Shore and in Mont\u00e9r\u00e9gie.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Why choose cellulose after attic decontamination?<\/summary><div class=\"nova-faq__a\"><p>Cellulose fits well in the nooks and crannies of the attic and offers good thermal and acoustic performance at a competitive cost. It is an ecological choice, made of recycled materials, to replace insulation soiled by rodents. This is a common option for homes in Longueuil or Saint-Hubert.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Is cellulose treated against fire and pests?<\/summary><div class=\"nova-faq__a\"><p>The cellulose we use is treated with additives that make it fire-resistant and less attractive to certain insects. However, no insulation replaces closing entry points to block rodents. It is part of an approach combining exclusion and sealing.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">How is the installation of cellulose insulation carried out?<\/summary><div class=\"nova-faq__a\"><p>After decontaminating and preparing the attic, our technicians blow the cellulose with a snowblower until the desired thickness and insulating value are reached. The distribution is adjusted to evenly cover the surface. The product is applied according to the standards in force.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">Do you offer a warranty on cellulose insulation?<\/summary><div class=\"nova-faq__a\"><p>We aim for a sustainable installation evaluated according to each project, without absolutely guaranteeing all the conditions of the building. A leaky roof, poor ventilation or new animal intrusion can affect the insulation, which is the responsibility of the owner. Our technicians advise you on preliminary corrections.  <\/p><\/div><\/details><details class=\"nova-faq__item\"><summary class=\"nova-faq__q\">How much does cellulose insulation cost?<\/summary><div class=\"nova-faq__a\"><p>The price is established on the basis of evaluation, depending on the surface area, the desired thickness and the access to the attic. An inspection in Boucherville or elsewhere in Mont\u00e9r\u00e9gie allows for a fair estimate.
