Exterior Rafter End
Polure exterior rafter end provides decorative roof overhang details with high-performance resistance to outdoor weathering. Crafted from high-density rigid polyurethane (150-220 kg/m³), this rafter tail extension replicates traditional carved timber rafter ends without decaying, splitting, or rotting over time. Its closed-cell formulation keeps water absorption under 1%, safeguarding roof structures against moisture, frost damage, and insect nesting under eaves. Engineered to remain structurally dimensionally stable in temperatures spanning -100 °C / +80 °C, it carries a B2 fire safety rating. Factory-coated with white acrylic technical primer, it requires dual fixing with continuous polyurethane assembly adhesive and countersunk screws. Finish with UV-resistant exterior paint.
Frequently Asked Questions
What material is Polure exterior rafter end made of?
Polure exterior rafter end is made of high-density rigid polyurethane (150-220 kg/m³), engineered with wood-like durability and B2 fire safety.
Will exterior rafter ends rot or deteriorate under roof eaves?
No, with water absorption below 1% and tolerance from -100 °C / +80 °C, exterior rafter ends will not rot, warp, or attract pests.
How are exterior rafter ends mounted to the roof fascia or wall?
They are mounted by applying continuous PU assembly adhesive on contact edges and securing with countersunk screws. Joints are filled and painted with UV-resistant paint.
Do exterior rafter ends support structural roof loads?
No, polyurethane rafter ends are decorative non-load-bearing architectural elements.
Can silicone be used to bond exterior rafter ends?
No, silicone is strictly forbidden because it cannot withstand outdoor exposure loads. Use only polyurethane assembly adhesive.
