North West Roofing Supplies stock and supply quality manufactured Velux roof windows and skylights.

Quality requirements
Quality is a major priority at VELUX and they devote extensive resources to testing, quality control and market testing to ensure that their products meet all quality requirements.

In their test department, products are continuously exposed to a variety of tests as an integral part of our efforts to develop and improve their products.

They expose their products to extremes of climates and expect them to function perfectly in constant daily use, year-in, year-out.

ISO 9001
The VELUX factories have been certified according to ISO 9001, and a roof window is designed and manufactured in accordance with relevant international standards.

In specific areas, such as watertightness, VELUX has introduced its own standards that are stricter than international standards.

In the countries where VELUX was first established, it is still possible to find working windows that were installed more than 40 years ago – the best possible proof of durability.
