Reynaers slimline 68 window system is the ideal choice for renovation projects and for use in residential new builds. It provides superb weather resistance and excellent levels of insulation.

Slimline 68 vents can be glazed from both the interior and exterior, and are available with a standard or HI insulation level.

The slimline 68 is perfectly suited to both contemporary and older, more traditional properties.

What is the best thickness for aluminium windows?

To ensure robust strength and safety, it is recommended that aluminium window profiles have a minimum thickness of 1.2mm. This specification ensures that the design can effectively bear the weight of the glass and maintain structural integrity.

Why aluminum windows are better than uPVC?

Aluminium is generally known for its superior strength compared to uPVC. As a result of this strength, aluminium windows have a sleeker appearance and can accommodate larger glass surfaces within their frames. Consequently, they have gained significant popularity in the realm of commercial and public constructions, such as schools, offices, and government buildings.
