PART L Compliance
Using Sheerline's unique Thermlock® technology, our Lift & Slide Patio offers industry leading thermal performance.
Fully Part L compliant, it comfortably achieves a U-value of 1.4 w/m2k using standard low-emmissivity double glazing, whilst in its triple-glazed specification it achieves an incredible U-value of just 1.0 w/m2k. This meets more stringent project requirements and the increases in performance demanded by Building Regulations.
Suites perfectly with the entire Sheerline® range
Over 30% slimmer than similar patio doors.
