Why orientation matters
Orientation helps decide whether to prioritise thermal insulation, solar control, airtightness, ventilation, glass specification or external protection.
North-facing facades
North-facing rooms often need more attention to heat loss and limited sunlight. Insulated profiles, low-emissivity glass, effective seals and careful installation are important.
South-facing facades
South-facing rooms receive more sunlight. Insulation may need to be combined with solar control, especially in warm regions or with large glazed areas.
East and west-facing facades
East receives morning sun while west can accumulate heat in the afternoon. West-facing rooms may benefit from stronger solar-control measures.
Noise, wind and real use
Orientation is only one factor. Street noise, prevailing wind, building height, shutter box, opening type and room use also matter.
Moving forward without deciding everything
You do not need to choose the system from the start. Leave your details and a Ventanas Cortizo network store can guide you.
