At Conservatech Home Improvements Ltd, we believe our customers deserve the very best - both in product quality and long-term performance. That’s why every single Warm Roof installation we carry out uses the award-winning WARMroof system from Prefix Systems. Prefix have set the benchmark in the industry for innovation, structural integrity, and thermal performance. Their WARMroof is engineered to deliver exceptional insulation while still allowing us to integrate Hybrid Climate Glass panels that flood extensions with natural light - exactly what our customers want. What sets Prefix apart is their uncompromising attention to detail. Every component is precision-manufactured, every joint engineered for longevity, and every roof system rigorously tested. The result is a warm, comfortable, quiet living space that looks stunning and performs flawlessly all year round.
