Frequently asked questions about the Windowsills category
Windowsills — what are they and what are windowsills used for?
Windowsills — are horizontal surfaces in the window opening that serve decorative and functional purposes: they support and protect the window frame, provide space for plants and items, and finish the interior. Our range includes plastic (PVC), wooden, aluminium and stone windowsills from brands such as Opus and Vox.
What materials are windowsills made of and how do PVC, wood and stone windowsills differ?
Our windowsills come in PVC — moisture-resistant and low-maintenance; wooden — warm appearance and eco-friendly but need treatment; stone — very durable, scratch-resistant and bear heavy loads. Choose based on moisture exposure, desired look and load requirements.
Plastic windowsills — what sizes and typical depths are available for PVC windowsills?
PVC windowsills are commonly offered in depths of 250–400 mm and lengths of 1570, 2170 and 3000 mm, as with OPUS models (e.g. 250x3000, 400x2170). These sizes fit a variety of window openings and installations.
Stone windowsills — when should you choose a stone windowsill?
Choose a stone windowsill when you need high durability and mechanical resistance: stone withstands scratches, moisture and thermal changes, making it ideal for kitchens and heavy-use areas. In our range stone options are positioned as premium, long-lasting solutions.
Windowsills for an apartment — which models suit living rooms and bedrooms?
For apartments choose PVC windowsills with matte or glossy finishes or wooden windowsills for a warmer look. Typical depths for living spaces are 250–400 mm depending on the window niche and interior style.
Which windowsill to choose for kitchen or bathroom — moisture and heat resistance?
For kitchen and bathroom choose moisture-resistant PVC windowsills or stone windowsills: PVC handles splashes and condensation well; stone resists high temperatures and heavy wear. Wood requires extra treatment and is less recommended.
Opus and Vox windowsills — what are the main differences between the brands?
Opus offers a wide range of PVC windowsills in various widths and lengths (e.g. 250x3000, 400x2170) with different end cap options; Vox focuses on high-quality finishes and alternative designs. Both brands prioritise durability and moisture resistance.
How to measure a windowsill before buying — which dimensions matter?
Measure the depth (from the inner edge of the window reveal to the interior face), the required length, and allow space for end caps. Common depths in our range are 250, 300, 350 and 400 mm; lengths include 1570, 2170 and 3000 mm.
What end caps and accessories are needed to install a PVC windowsill?
PVC windowsills require end caps, mounting brackets/angles and sealing tapes. OPUS models often offer two-sided or VTR+ end cap options that neatly close edges and protect against moisture.
Buying a windowsill — what to check for quality and durability?
Check the material (PVC, stone, wood), thickness and reinforcements, surface resistance to moisture and scratches, and accurate dimensions for your opening. Opus and Vox provide reliable options with various sizes and finishes for long service life.
