Frequently asked questions about the Internal doors category
Internal doors — what are they and what are they used for?
Internal doors are interior/inter-room doors for homes, apartments and offices; available in sizes from 7x21 to 10x21. SityPro.com offers styles from classic to modern in various materials and finishes to provide privacy, sound insulation and interior styling.
What standard sizes of internal doors are available?
SityPro.com offers internal doors in standard sizes from 7x21 to 10x21 (width×height in inches). Measure your door opening and choose the nearest size; contact the supplier if you need non-standard dimensions.
What materials and finishes are offered for internal doors?
SityPro.com stocks painted white doors, oak and pine finishes, graphite tones and melamine surfaces. You can also find smooth panels and models with glass inserts (for example JÄÄKLAAS) and various textured or enamelled finishes.
What glass options are available and where are they suitable?
Glass variants like SILE 1R with JÄÄKLAAS are available in clear and frosted options. These doors suit hallways and kitchens to transmit light between rooms; choose frosted glass for greater privacy.
How do doors for a house differ from apartment doors?
Differences are usually in design and sound insulation: apartment doors often have tighter seals and denser panels for noise reduction; house doors offer more style and glass options. SityPro.com carries both economical models and heavier constructions with improved sound insulation.
What opening directions are available (left/right)?
The catalogue includes both right- and left-hand doors (e.g. CREMONA 6RK 8X21 right). Determine the handing by looking from the closing side: hinges on the right = right-hand door, on the left = left-hand door.
What sound insulation do internal doors provide and how to improve it?
Sound insulation depends on construction: solid panels and seals perform better than hollow doors. Improve insulation by choosing a denser model, adding sealing strips and a threshold seal.
Will a 10x20 door fit a standard 10x21 opening?
A 10x20 door is one inch shorter than a 10x21 opening, so it won’t fit correctly without adjustment. Choose a 10x21 door or allow for trimming/adjustment of the frame during installation.
How to choose an interior door by interior style?
Match the door to your room style: classic rooms suit panelled or painted white doors; modern interiors pair well with smooth graphite or oak finishes. SityPro.com includes models like CREMONA, SILE, CLIF and MAGNUS that cover different stylistic needs.
Which models are suitable for bathroom or toilet?
Choose doors with moisture‑resistant finishes or melamine surfaces and frosted glass if light is needed (e.g. JÄÄKLAAS variants). Use seals and a moisture‑resistant frame to extend the door’s service life.
