Treforest Glass Information

Sealed unit manufacturer, with 35 years experience in the industry. We specialist in high specification units down to as low as 0.3Wm2K. Double glazing @ 0.9 W/m2K. We have a 'can do' attitude and have customers the length and breadth of the country who come to us for things that other glass companies cannot do or for specialist heritage glass that customers cannot find elsewhere. We specialise in units for joineries and have developed units with joineries in mind, allowing them thinner profiles which customers crave and offering them savings on their timber. We are an EN1279 company, our quality standards are extremely high as we understand that joinery customers have high expectations with regard to the quality of their sealed units matching that of the timber windows. We are a 'think outside the box' company.
