ThermoProof has been manufacturing windows and doors on Vancouver Island since 1977. We work with Certified Window Installation Partner BC, who want dependable product, clear expectations, and support that does not disappear when a homeowner calls back six months later.
We are a manufacturer first. Our installation partners are a critical part of how our products perform in real homes.
As an installation partner, you are working with a full range of ThermoProof window and door systems,
All products are manufactured locally, NAFS tested, and designed for West Coast and coastal environments.
This consistency reduces on-site improvisation and post-install issues.
We support installers by being clear about roles, standards, and follow-through.
We support installers with clear responsibilities and a defined service pathway.
Installers are not looking for promises. They are looking for fewer problems.
Our goal is to remove that friction so you can focus on doing good work.
ThermoCare is ThermoProof’s ongoing support program. It is included with every product.
ThermoCare exists so installers are not left handling manufacturer issues alone
We work with installation partners through an application and review process.
We focus on quality and consistency, not volume at any cost.
In all cases, the goal is the same. High-performing windows, installed properly, with long-term support behind them. whether it’s a new construction project, a full home renovation, or a simple window replacement—the goal remains the same: to deliver high-performing windows that are installed correctly and supported for the long term. True window performance is not just about the product itself, but about how all the elements work together to create comfort, efficiency, and reliability for years to come.
We succeed when our partners succeed.
If you’re mainly looking for a price list without project context, we may not be the right fit. If you value standards and long-term accountability, we should talk.
