Standard windows generally come in two sizes (1.23 m x 1.48 m and 1.48 m x 2.18 m). Despite the standard sizing there are still differences concerning the building depth and the sealing and locking systems depending on the type of material chosen.
For example, standard vinyl (uPVC) windows come requiring an installation depth of 70 cm, aluminium windows 72 cm and wooden windows need a depth of 78 cm.
Special attention also lies on the various systems of sealing used to ensure highly effective thermal insulation while simultaneously lowering heating costs.
According to the guidelines outlined in the EU Energy Saving directive (EnEV), 4 the maximum thermal transmission coefficient (U-value) should be 1.30 W/(m²K) or less.
These requirements are fulfilled by our uPVC windows thanks to the 5-chamber sealing systems which use either a compression seal or a center seal to ensure optimum thermal insulation.
This U-vale can be improved further with double glazing to roughly 1.1 W/(m²K) and with triple glazing to 0.5 – 0.7 W/(m2K) virtually halved.
Optimum energy efficiency is best achieved by using multiple glazing on all standard windows of aluminium, as in the basic version these only come with a 3-chamber system giving a U-value of 1.4 W/(m2K).
In contrast to uPVC and aluminium windows, wooden window profiles impress due to their very natural look, and also because of their thermal drip cap seal, that protects the frame and sash not only against UV-rays, but also against damp seeping into the unit. Multiple glazing helps to attain the U-value of 1.30 W/(m²K). Windows 24.com offers energy efficiency and good living through its high value products made in Germany.
A pleasant, warm atmosphere and the feeling of being secure – standard windows draw attention because of the optimum thermal insulation they offer and due to the ideal security systems which are available for them.
Manufactured in aluminium they are typically fitted with a 4-fold locking system with steel-mushroom-locks (mushroom head locking).
Mushroom shaped pins lock into the locking plate set into the frame and prevent the window from being lifted out of its anchoring. An additional lockout device and an incorrect latch position block protect against unwanted intruders.
For the best atmosphere in the home, high value standard windows provide a special level of soundproofing. The chambers within the 5-chamber seal system can be additionally fulfilled with a heat and sound insulating PVC foam material.
In combination with multiple glazing extremely good soundproofing can be attained which guarantees the recommended level of noise of 35 dB in residential areas is met.
