A comprehensive guide on how to overcome challenges posed by Building Regs and Specification. Building regulations are legal standards that ensure buildings are safe, energy efficient, and suitable for occupation. For windows & doors, they cover areas such as energy efficiency, ventilation, safety glazing, fire escape, accessibility and overheating. Having a good working knowledge of these specifications and keeping up-to-date with changes is a fundamental tool in any Contractors Armory
