Permanent Window Solutions has over 10 years experience in supplying and installing European Designed and Manufactured Windows & Doors. Our products (including the doors) are Energy Star Rated for Efficiency and our windows are rated Light Commercial to Commercial Grade by QAI Laboratories and by the CSA Fenestration Laboratory. We have offices, showrooms and warehouses in both Edmonton and Calgary with experienced installers who are supervised by our own in-house Engineers. Our products are designed and manufactured by REHAU, a multi-national manufacturer of Engineering Polymers meeting the higher standards of Europe. The key differentiators of our products are that they have compression seals, they offer tilt & turn capabilities, they have multi-point locks and meet the higher European standards for security (EN 1627), they have extremely high acoustic (sound cancelling) benefits and the quality of the hardware or components is first class. In addition, we have countless color options for the frames and we have guaranteed color sustainability.
REHAU windows can contribute to achieving LEED (Leadership in Energy and Environmental Design) certification for buildings. Their energy-efficient designs, including features like multi-chambered profiles and high-performance glazing, can help reduce energy consumption and improve a building’s overall environmental performance. This can translate into points towards LEED certification, which recognizes sustainable building practices.
Here’s a more detailed explanation:
- Energy Efficiency:
REHAU windows are designed with features like multi-chambered profiles and the ability to accommodate high-performance glazing (up to 2 inches). These features contribute to better thermal performance, reducing energy loss and improving a building’s overall energy efficiency. This can help a building meet LEED requirements for energy performance. - Material Sustainability:
REHAU uses high-quality PVC in their window profiles, and some of their products incorporate recycled materials. This can contribute to LEED credits for material selection and resource efficiency. - Contribution to LEED Points:
REHAU and their fabricators can work with building designers to integrate window systems into the overall building design and potentially earn LEED points, especially in areas like energy and atmosphere, materials and resources, and indoor environmental quality. - Beyond LEED:
Some projects using REHAU windows have achieved even more stringent standards like Passive House certification, which goes beyond LEED requirements for energy efficiency. This highlights the potential for REHAU windows to contribute to high-performance, sustainable buildings.
