Security

At CRK Windows we know that with control, comes peace-of-mind.

Unlike other double glazing companies, we manufacture all our products to measure in our own factories in Hemel Hempstead. We employ strict quality-controls and high-specification materials across all CRK products, so no matter what product you select from our vast range, quality and safety are never compromised.

Ask our sales team about our high-security internal glazing that can’t be removed from the outside and state-of-the art multi-point locking system for extra reassurance.
