Why choose an authorised specialist for your VELFAC or Rationel windows?
VELFAC and Rationel windows are premium products with specific hardware, seals, and mechanisms. A general glazier or window company may not carry the right parts, may not understand the system, and may inadvertently cause further issues by attempting a repair incorrectly. As an authorised VELFAC and Rationel distributor, we carry genuine replacement parts, understand the full product range, and can service your windows correctly — protecting your investment.
