Duraflex windows – improving your home with style.

At the heart of all Duraflex PVCu windows is a high-quality profile with multiple inner chambers for durability, strength and thermal performance.  Combined with our high-specification glass, your new Duraflex windows come with excellent energy efficiency and sealing, whether you choose standard double-glazed windows or enhanced triple-glazed models.

Even the seals provided with all Duraflex windows comprise the higher quality Q-Lon type, superior to rubber used on other windows and widely regarded as the best possible gasket because of its consistent performance across all temperatures and its thermal and acoustic properties. 

Your new Duraflex windows come in a fantastic choice of foil finishes giving a more luxurious look and feel. Available in smooth or textured finishes, you can choose modern grey, black or several shades of white and a great selection of wood effect finishes, including Golden Oak, Rosewood and Irish Oak.  All are complemented with a stylish choice of window handles in a choice of pleasing colours and finishes, all with a key locking facility.
