HIGH PERFORMANCE Energy Star® DOORS & WINDOWS

Lorendo High Performance doors and windows are Energy Star® certified, a symbol of excellence in energy efficiency. To display the Energy Star® logo, products had to undergo a series of tests in accordance with prescribed federal government procedures certifying that Lorendo windows comply or exceed Canadian energy efficiency standards. 

Energy Star® doors and windows save energy. They help maintain your comfort throughout the year. In winter, they help keep you warm, in summer, cool. They help reduce external noise. And, depending on the humidity level in your home, they may show much less condensation on the thermal glass in cold weather.

HOW TO CHOOSE DOORS AND WINDOWS BASED ON CLIMATIC ZONES

For the purposes of ENERGY STAR certification, Canada is divided into three climatic zones  (1, 2 and 3). Zone 1 is the hottest and Zone 3 is the coldest. Make sure to buy products that fit the climatic zone of your home or, at best, choose products that correspond to cooler areas to save more energy. Our sales representative can guide you in this process.

ADVANCED & EXCLUSIVE TECHNOLOGY

Our exclusive Heavy-Duty PVC profiles are tested at -30°C, -40°C, -50°C and surpass industry standards in terms of performance, strength and rigidity.

OPTIMAL AIR & WATER TIGHTNESS

Our exclusive Heavy-Duty PVC profiles are resistant to water, rain, thunderstorms, humidity, ice, wind and more…

ANTI-INFILTRATION
DESIGN

ANTI-INFILTRATION
DESIGN

Our exclusive Heavy-Duty PVC windows are made of 3 high-tech extruded and welded PVC profiles. Thanks to an integrated anti-infiltration design, our system of 4 ENERMAX weatherstrips (2 of which are coextruded on the PVC profile and then welded together with the PVC frame) ensures optimal long-term air & watertightness as well as thermal performance.

PERFORMANCE TESTS

PERFORMANCE

- Tested at -30°C, -40°C, -50°C and -60°C and under different temperatures and climatic conditions to demonstrate their resistance to harsh conditions.

- Tested at 500, 1000, 1500, 2000 and up to 4500 opening and closing cycles.

- Tested in accordance with the current Québec Building Code NAFS-08 standards & the 2010 Canadian Building Code AAMA / WDMA / CSA / 101 / I.S.2 / A440 and complied with ASTM D4726 standards.

Certification

Certification

Certified PVC-AAMA-303, meaning they have passed the weatherability, impact resistance, crack resistance, tensile strength, resistance to temperature changes and linear expansion coefficient tests.

SUPERIOR INSULATION

UN DESIGN EXCLUSIF
multi-chambres

Absorbs pressure variations and remains stable. .
Our Heavy-Duty PVC profiles and multi-air chamber configuration are robust and designed to absorb pressure variations caused by temperature differences between the outer and inner regions of the window. Lorendo High Performance windows remain stable, do not warp and do not crack in large temperature changes such as heat and cold.

ARGON GAS INSULATION +
STAINLESS STEEL AIR FRAME

Minimizes condensation, ice formation and resists corrosion.
Lorendo high performance windows are equipped with sealed glass units combining Argon gas and the stainless steel air spacing frame system INTERCEPT™, an open U profile renowned for its incomparable strength, durability and corrosion resistance. This spacer does not have notched corners, making it the most resistant in the industry and ensuring the most reliable thermal performance in terms of argon retention with a less than 0.1% rate of loss annually. Because of greater flexibility during major temperature variations found in Quebec, it remains airtight, minimize condensation, absorb humidity and resist corrosion.

LOW-EMISSION
INSULATING GLASS

Keep warm in winter and cool in summer.
Lorendo high performance windows are equipped with SUNGATE ™ 400 Low-E insulating glass with low emissivity. This high quality glass combines the energy performance and comfort characteristics needed for the cold regions of Quebec and North America. This high performance glass effectively stores heat, which reduces your heating costs. It keeps you warm on cold winter nights and cool on hot summer days.

STRUCTURAL PERFORMANCE

THE RIGIDITY AND ROBUSTNESS OF OUR FRAMES

The frames of our Lorendo doors and windows are strong, sturdy and efficient. Our anti-twist PVC jam extensions and frame systems are designed to stay rigid during maneuvers. They therefore facilitate the installation process and minimize adjustments making you save time and money in your project! Our frames are available in several types and depths 4-1/2 ”, 5-5/8 ” and 6-9/16 ”. Our jam extensions are offered in several options: pine, jointed pine, wood covered with PVC.
