Matkel carries both. Gypsum crown molding gives a smoother, lighter finish and works well in living rooms. Poly molding is tougher for light moisture and impact, making it better for corridors or high-traffic areas. Match the adhesive, wall surface, and edge thickness before purchase to avoid uneven edges.
Yes. High humidity and summer heat can affect molding, especially in kitchens or bathrooms without good ventilation. Choose moisture-resistant materials and a protective sealer, and install after the gypsum board has fully set. In Jeddah or the Eastern Province, check edges after a few weeks for swelling or cracking.
Sizes typically range from about 5 cm to 15 cm, depending on ceiling height and room design. Lower ceilings usually suit 5 to 8 cm profiles, while taller ceilings allow 10 to 15 cm to highlight details. Request samples or share wall and ceiling measurements, including each wall length and window corners, to reduce waste.
Yes, if the molding is thick enough, you can place an LED strip behind or inside the crown cavity. Use a channel that allows airflow, secure the adhesive, and protect the cable from pressure. Choose low-heat lights and a suitable driver, which adds visual depth to living rooms and kitchens without direct glare.
Matkel provides warranty on select ceiling crown molding models, depending on material and product type. Check the product card for the warranty period and conditions, since gypsum and poly may differ in moisture and vibration resistance. Keep your invoice and model reference, and contact customer service before installation if you need confirmation on coverage or replacement.
