LK78X – exceptional energy efficiency
The easiest way to improve the energy efficiency of a building is to ensure its proper thermal insulation. Our extremely tight Purso LK78X window and door system combines an exceptionally low U value and superb usability in any weather conditions with highly stylish design.
LK78X is a safe choice when you need inward or outward opening doors, sliding doors or fixed, or inward or outward opening windows. Throughout its life cycle, the system requires minimal care and maintenance, and it is fully recyclable after it has reached the end of its service life.
Surface treatment options
Anodizing
Anodizing provides aluminium with a surface that is resistant to corrosion, UV radiation, and wear. Different colours create a deeper, more refined style for the building – in addition to natural anodized silver, you can choose electrolytic colour-anodized shades such as bronze, black, and gold.
Powder coating
Powder coating creates an exceptionally durable painted surface. You can freely choose the colour shade and gloss level according to your preferences. At Purso’s in-house powder coating facility, various textured and pearlescent effects can also be achieved.
100% recycled Greenline aluminium
We will transition to using only Greenline aluminium in all our building system products during 2025. Aluminium is an excellent material for recycling, as it retains its qualities, and using it significantly reduces carbon dioxide emissions. Greenline aluminium is produced at Purso’s own remelt plant. The energy required to remelt aluminium is only about 5% compared to the production of primary aluminium. All aluminium alloys used in our production are fully recyclable at the end of their lifecycle.
