Ensure Maximum Energy Savings with Our Insulation Services in St. John’s

Need Insulation for Your Attic? 

Our technicians can install cellulose insulation to reduce airflow to and from your attic. 

When it comes to heating, you need a solution that gets the job done while minimizing the environmental impact that conventional heating and cooling systems pose through their energy consumption. 

Shield Insulations offers a fitting alternative that can provide adequate levels of comfort while reducing energy costs. We offer a variety of insulation services for residential and commercial properties in St. John’s that help in maintaining your desired indoor temperature. Additionally, installing an insulation membrane like the cellulose ones we work with keeps heat in and prevents humidity from entering indoors. This can subsequently protect piping and air vents from the ill effects of condensation or freezing. 


If you are a homeowner in the Avalon Peninsula region, you can benefit from installing thermal insulation in several ways. Thermal insulation can improve the energy efficiency of your home or office, protect utility pipes and prevent air exchangers from freezing, while also offering fire protection and sound absorption qualities. Commercial insulation services are available on request. You can contact us for more information about the commercial solutions we provide.
