Penot: The Art of Vision. Crafted for Discerning Homes

Pricing depends on the window style, size, glass specification, quantity, and installation package chosen. Custom shapes such as arch or curved windows involve additional manufacturing complexity. Larger fixed or sliding windows carry a different price structure to smaller sliding or awning windows due to the glass area involved. Penot is transparent with pricing and your written quote will itemise every window by size, specification, and price with no hidden fees.

Yes, and they perform particularly well here. Perth’s climate creates a dual challenge of intense summer heat that regularly exceeds 35 degrees and cool winter nights. A standard single-pane aluminium window conducts heat directly, making your home hotter in summer and colder in winter while forcing your air conditioning and heating to work harder.

Penot’s thermally broken double glazed windows interrupt heat transfer at two points. The argon-filled glass cavity slows heat movement through the pane, and the thermal break in the aluminium frame prevents the frame itself from acting as a conductor. The result is a home that stays meaningfully cooler on Perth summer days without being entirely reliant on air conditioning, and that retains warmth on winter nights.

The right style depends on your room layout, ventilation goals, and architecture. As a general guide:

Tilt & Turn windows are ideal for bedrooms and living rooms. They tilt for gentle, draught-free ventilation or open fully inward for maximum airflow and easy cleaning.

Sliding windows suit contemporary homes and tight spaces where a sash cannot swing outward.

Casement windows open outward on a side hinge and are excellent for catching the Fremantle Doctor in main living areas.

Awning windows hinge at the top and stay open during light rain, making them perfect for bathrooms, laundries, or any room needing constant airflow.

Stacking windows are designed for large openings, with panels that stack to one side to blur the boundary between indoors and out.

Arch and Curved windows are custom-manufactured for feature walls, heritage facades, and bespoke builds.

For most Perth homes, double glazing with thermally broken aluminium frames and Low-E glass provides excellent thermal and acoustic performance that easily justifies the investment. Triple glazing makes sense if you are in a high-noise location near roads, airports, or industrial areas, if you want the absolute maximum thermal efficiency for a passively designed home, or if you are in an elevated location exposed to strong winds and temperature extremes. Our team can model the performance difference for your specific situation.

Based on performance data from comparable Australian climates, double glazing with thermally broken frames can reduce a home’s heating and cooling energy consumption by up to 40% compared to standard single-pane aluminium windows. The exact saving depends on your home’s insulation, orientation, and how many windows are upgraded. Homes on north and west-facing elevations, which receive the most direct sun in Perth, typically see the largest reductions.

Low-E (low-emissivity) glass has an invisible metallic coating that reflects radiant heat while allowing visible light to pass through freely. In summer it reflects the sun’s radiant heat outward, keeping your home cooler. In winter it reflects internal warmth back into the room, reducing heat loss. For Perth’s climate with its intense summer sun and cool winters, Low-E glass is strongly recommended and is included as standard in most Penot specifications.

A thermal break is an insulating barrier, typically a glass-reinforced polyamide strip, inserted between the outer and inner sections of the aluminium frame. Without it, aluminium conducts heat and cold rapidly from outside to inside, undermining the insulating performance of the glazing. With a thermal break, the inner frame stays close to room temperature regardless of outside conditions. This is why thermally broken aluminium outperforms standard aluminium significantly in both thermal and condensation performance.

Significantly, yes. Double glazing can reduce external noise transmission by 30 to 50% compared to single-pane glass. If you are in a high-noise location near major roads, under flight paths to Perth Airport, or in a busy suburb, triple glazing offers even greater acoustic attenuation. Our team regularly installs in suburbs like Belmont, Cloverdale, and Redcliffe that are affected by aircraft noise, with excellent results. The key is matching the right glass specification to your noise profile, which our team will advise on during a free consultation.
