Its fixed, non-opening construction makes it ideal for areas where ventilation is not required, but you still want a bright and comfortable interior.\n\nCombining secure double glazing with a durable, UV-protected polycarbonate dome, the DXC-C P4 provides a practical daylighting solution for homes, offices and commercial buildings. Its clean design and robust construction make it suitable for projects where reliable performance and low maintenance are important.\n\n\u003ch3\u003eEnhanced Security with P4A Glazing\u003c\/h3\u003e\n\nSecurity is at the heart of the DXC-C P4. The window features \u003cstrong\u003eP4A laminated anti-burglary glazing\u003c\/strong\u003e, offering a higher level of resistance to impact and attempted intrusion. This makes it a suitable option for spaces where additional security is an important consideration alongside natural daylight.\n\n\u003ch3\u003eExcellent Thermal Performance\u003c\/h3\u003e\n\nThe DXC-C P4 is designed to help minimise heat transfer through the roof. It achieves a whole-window U-value of \u003cstrong\u003e1.2 W\/m²K\u003c\/strong\u003e, while the glass has a U-value of \u003cstrong\u003e1.1 W\/m²K\u003c\/strong\u003e. This helps support a comfortable indoor environment throughout the year and can contribute to improved energy efficiency.\n\n\u003ch3\u003eDurable UV-Protected Dome\u003c\/h3\u003e\n\nThe polycarbonate dome is protected against UV exposure on both sides. This helps prevent discolouration over time while maintaining good daylight transmission. The durable dome provides an additional layer of protection for the glazing and is designed to withstand regular exposure to outdoor conditions.\n\n\u003ch3\u003eInsulated UPVC Kerb Upstand\u003c\/h3\u003e\n\nThe Fakro DXC-C P4 is supplied with a \u003cstrong\u003e150mm insulated UPVC kerb upstand\u003c\/strong\u003e. This provides a strong and stable foundation for the roof window while contributing to its overall thermal performance and insulation.\n\n\u003ch3\u003eFixed Non-Opening Design\u003c\/h3\u003e\n\nThe fixed construction means the DXC-C P4 does not provide ventilation. Instead, it is designed specifically to bring natural light into rooms where opening the roof window is not necessary. With no moving opening mechanism, the design also helps keep maintenance requirements to a minimum.\n\n\u003ch3\u003eFlexible Installation\u003c\/h3\u003e\n\nThe DXC-C P4 is suitable for flat roofs with pitches between \u003cstrong\u003e0° and 15°\u003c\/strong\u003e, making it adaptable to a variety of roof designs and building types. An optional \u003cstrong\u003e15cm raised base\u003c\/strong\u003e can also be used where additional installation height is needed or where it suits the construction of a deeper roof structure.\n\n\u003ch3\u003eCompatible with Accessories\u003c\/h3\u003e\n\nFor greater control over light and comfort, the DXC-C P4 is compatible with suitable internal and external accessories, including blinds and shading options.
