Synseal’s WarmCore bi-fold door available from AstraFrame

WarmCore exploded hinge detailWarmCore by Synseal is now available from AstraFrame. The innovative aluminium folding, sliding door provides a range of highly energy efficient and secure door options.

WarmCore’s aluminium frame features a multi-chambered thermal core which outperforms traditional thermally broken aluminium door systems. Installed with standard 28mm double glazing, it achieves a U-value of 1.5 W/m²K, this can be reduced to 1.4 if low-E glass is used. When fitted with 44mm triple glazing the door achieves a U-value of 1.0 W/m²K. WamCore’s energy efficient design far exceeds Building Regulations so it’s ideal for highly insulated houses or extensions.

The slim frame of a WarmCore patio door has a 70mm front-to-back sash and is suitable for installation in residential and commercial projects. The folding sliding door leafs are triple sealed, they eliminate draughts and make sure it is absolutely weather tight.

As standard, the door has PAS24 and Secured by Design accreditations, confirming excellent strength and security standards from independent, third party testing. WarmCore’s hardware partner, ERA provides a ‘Five-Star’ security guarantee, too.

WarmCore is easy to install with clip-in beads and hinge adjustment packers alongside a smart aluminium track which enables speedy fitting without de-sashing. It is easy to adjust with plain, WarmCore profilepivot roller and espag hinges providing +/- 1mm for fine tolerance adjustments during installation. So whether you’re fitting it yourself or using one of AstraFrame’s recommended installers, it will be an easy process.

WarmCore can be used to manufacture an array of door styles including single, French and bi-fold, all with flexible threshold choices. WarmCore is available in a range of colours, suited with the Synseal conservatory roof and orangery range, with the added option of dual colour frames.
