Awnings & Casements

Awnings & Casements

Alspec’s® range of Awning and Casement windows are ideal for suburban housing, multi-unit residential, hotels and commercial applications. The Awnings and Casements can integrate with a number of Alspec® Commercial Framing systems by using different awning adaptors.

The 35mm and 50mm sashes offer the benefit of overlapping internal and external seals to achieve superior weather performance. The 443 30mm sash sits inset of the framing and can offer a flush appearance.

Various glazing options for single and double glazing are available. All Awnings and Casements can be used with a range of available stays and operated with Chainwinders or Cam handles, locking or non-locking. With the use of our Chainwinder adaptor insect and security screens can easily be added from the inside of the building.
