Learn MoreCommon questions, answered.
What is a casement door, and how is it different from a sliding door?
A casement door is hinged and swings fully open inward or outward, giving a wider opening and more ventilation than a sliding door of the same width — well suited to wardrobes, kitchens, and bathrooms.
Are casement doors durable in Indian conditions?
Yes — the aluminium frame resists corrosion, heat, and sunlight, and is tested to ASTM and JIS standards for harsh weather performance.
What upkeep do casement doors need?
A wipe with a damp cloth every couple of weeks is enough — the TEXGUARD coating protects the surface from dust and general wear.
