«J'ai constaté que la trappe Maximum installée à la sortie de mon Jenn-Air n'était pas aussi étanche et efficace que décrite et qu'il y avait énormément d'air froid qui entrait l'hiver dans ma cuisine. J'ai donc appelé l'équipe Thermo-Trap et le problème a été corrigé. Thermo-Trap a aussi mis un frein aux entrées d'air de ma salle de bain et de ma sécheuse. Un travail compétent a été réalisé et je constate maintenant d'excellents résultats! Je recommande à tous l'efficacité des trappes Thermo-Trap!»
«J'ai 3 trappes d'aération dont les sorties sont au dessus du stationnement de mon voisin, celui-ci laisse rouler sont gros camion 30 minutes le matin... J'avais donc une odeur d'essence et du CO2 en quantité dangereuse pour ma santé et celle de mon petit bébé dans mon condo. J'avais donc absolument besoin d'un miracle comme Thermo-Trap de Normand Blanchard, un produit du Génie québécois-acadien. Si j'avais l'odeur, j'avais également de l'air froid provenant de ma trappe de ventilation de salle de bain et de ma hotte de cuisine. De plus, l'intérieur de ma sécheuse me donnait la température extérieure de la journée! Tous ces problèmes sont résolus grâce à Thermo-Trap!»
«Nous avons particulièrement apprécié l’installation professionnelle de THERMO-TRAP. L’isolation des tuyaux ainsi que le calfeutrage autour de la trappe de ventilation sont incomparables!»
