Pass on promises of enhanced thermal performance and security
Our trade supply of timber look windows are registered with the BFRC under their window energy rating scheme. By using the quality Deceuninck profile, we are therefore able to offer our customers efficient energy ratings of A, which also act as key selling points for your potential customers.
The experts here at Dempsey Dyer are also able to simulate any glazing specification to prove the thermal performance (the U-value of the whole frame). Our glazing allows ample sunlight through while retaining heat in the home. Our two main areas of concern were its structural integrity and weather tightness. These are two British Standards that the timber look flush sash window has passed with flying colours.
