Sternfenster now supplies doors constructed using the latest Gripcore technology, which is designed to make composite doors stronger, heavier, warmer and more secure.

They are also said to offer unique opportunities for installers, with modern design and glass options.

Gripcore doors, developed by Doorco, are made using a hybrid of cross-laminated engineered hardwood, laminated veneer lumber (LVL) timber, and hardwood stiles and rails, then pressed with 4mm GRP skins. According to Doorco, this design means these doors will not move, bow or twist more than 3mm, require minimal maintenance, and have security ‘built in’ thanks to this unique construction.

“Gripcore technology is a fantastic evolution of the composite door,” Sternfenster’s sales director Nathan Court said. “Our doors, built using Gripcore technology, iron out many of the irritations that installers have had with traditional composite doors, namely, warping and cracking.

Gripcore doors can achieve an ultra-low U-value of 1.0W/m²K or better; and they feature multi-point locking mechanisms and high-grade security hardware.

Sternfenster has a range of marketing literature which showcases all composite door styles and options.

“Also, by partnering with Sternfenster, you have access to Sternfenster Plus, a next generation, online resource that gives you everything you need to run your businesses more efficiently,” Nathan said.

“This includes a live production capacity feed that allows you to check on the status of your quotes, contracts and deliveries, download comprehensive training and marketing materials, and visit a regularly updated news feed.”
