Hardwood vs softwood
Timber casement windows are constructed from either hardwoods or softwoods – each variant has its own benefits. Although it’s almost impossible to tell the difference visually, hardwood timber casements don’t expand and contract as much compared to softwoods when the temperature changes. However, softwoods are inherently more workable than hardwoods. Because of they’re much less rigid, they can be more easily carved and shaped to fit smaller spaces and create more complex joints. In order to ensure that all our timber is sourced from sustainably managed forests, we offer either European Redwood for softwood, Oak for hardwood or Accoya. These materials allow us to produce Casement Windows that not only look great but are designed to be secure and are expertly engineered to prevent warping or rotting. We offer Accoya, Oak for Hardwood and Engineered Redwood for Softwood.

At Core Sash Windows, all of our windows come with a 10-year guarantee and are FENSA certified. This means the fitter has installed anything from our product range in accordance with strict health, safety and quality standards - meaning you’re getting the best results.
