The Fenplast products we sell

Seven products, all of them in the showroom in Saint-Alphonse-de-Granby. Open them, compare the handles, look at the frame cross sections before you choose.

Premia: what is new

Premia is Fenplast's new-generation casement and awning window.

Two versions: PVC, or a PVC and aluminum hybrid with aluminum cladding on the outside. PVC suits contemporary and traditional homes alike. The hybrid, with its straight lines and angled glazing beads, leans contemporary.

  • Patented corner sealing on the hybrid: an injection channel block guides the silicone to the joint.
  • Sash weatherstrip concealed from the inside: no visible joint to clean.
  • Redesigned screen frame, minimalist aluminum extrusion profile, black fibre mesh.

PVC or hybrid: the only real choice

Both Premia versions share the same hardware and the same glazing. What changes is the outside and the frame.

« Le choix du modèle et du vitrage a été très facile avec les conseils de Michael Gauvin. Jonathan a fait une installation professionnelle, en prenant soin de préserver les moulures de bois qui entouraient l'ancienne porte du côté intérieur. »

Frequently asked questions

Who installs my windows?

Our own team. Five installers are in house, on a team of sixteen. The person who measures at your place and the one who installs work for the same company, not for a passing subcontractor.

What does the Fenplast warranty cover, and does it follow the house?

The Fenplast limited lifetime warranty covers the PVC frames and profiles, the seal of the sealed units and the built-in hardware. It is fully transferable to the next owner, provided that owner can produce the original contract or invoice. Every claim must first be addressed to the dealer that sold the products, which means to us.

Are the products ENERGY STAR certified?

We offer ENERGY STAR certified products, including models that meet the window requirements of the Novoclimat program. Certification varies from one model and glazing configuration to another: we confirm which one applies to your project when we quote it.

How long between the quote and the installation?

The lead time depends on the product, the season and the manufacturer's order book. We confirm it when we quote, with a date, not a vague range. Every quote request gets an answer within 48 business hours; the quote follows the measuring visit.

  • Aujourd’hui a eu lieu le remplacement de notre porte d’accès principale. On devait ouvrir 2 portes en bois, non étanches et pas efficaces du point de vue énergétique. On a maintenant une porte en acier performante. Le choix du modèle et du vitrage a été très facile avec les conseils de Michael Gauvin. Jonathan a fait une installation professionnelle, en prenant soin de préserver les moulures de bois qui entouraient l’ancienne porte du côté intérieur. La nouvelle finition du pourtour extérieur de la porte est parfaite et reproduit le détail des pourtours des fenêtres et autres portes de la maison. On a payé pour un produit de qualité et il a été bien installé.
