Our supply chain currently covers all the major European markets, with our home markets in Denmark and the United Kingdom. Our roof light systems are constantly reviewed by the in-house design team to ensure that any 'new and improved technologies' are taken advantage of and where necessary developed, ensuring our products are always performing to expectations & beyond. The systems are all tested and certified to ensure that the glazing is designed to cope with the harshest of environments and to provide your client with all year round comfort and protection. VITRAL strive to reduce the environmental impact over its extended years of use, compared to low quality, cheap and cheerful inferior bars and glass constructions.
