Whether you’re searching for a frame that simplifies fitting, a casement to lower EPC, or the option to offer increased security for your clients – each and every Sierra frame is built from scratch to your exact specifications.

We can design virtually any frame for any installation. We use 70mm internally glazed PVC-U windows and offer an extensive range of styles and opening features. To make your job easier, you could opt for a pre-applied gasket integrated system, which features fitter-friendly click fit beads.

And because only perfection will do, each frame passes through multiple checkpoints as it makes its way through our factory. You will also be assigned a coordinator who will keep you updated at every stage. Once your frame has met our impeccable standards, we can deliver it anywhere in the UK.

If you’re searching for an expert supplier with a complete design to door service, contact our team today.
