High Performance Double Glazing


Not only do our windows and doors meet the highest Energy Saving standards but our REHAU double glazing has also been tested in accordance with the highest requirements of BS7412 for the standard of a manufactured window. This includes BS6375 for weather performance, making our double glazing superior in every form.


Our UPVC double glazing has excellent acoustic properties and is well known for its ability to reduce external noise. Our REHAU profile will bring down the noise levels in your Cardiff home by as much as half, which means you’ll be able to enjoy a heightened degree of comfort throughout your home. These windows simply offer you more across the board.

Our UPVC replacement windows are manufactured from a unique compound that guarantees a smooth, high gloss finish. This ensures your windows retain their pristine appearance for many years to come. Your UPVC windows will never require re-painting, and will never rot or warp, ensuring your Cardiff or Newport home looks great for decades.
