Cresthaven Windows for Residential & Commercial

Impeccable Design

Offering Solutions to your window requirements

All windows feature a unique, innovative design with mechanically strong & secure glazing bead, and fully-welded joints for enhanced strength and performance. This ensures the highest standards of performance in quality, security and energy efficiency.

What are energy-rated windows?

Upgrading to energy-efficient windows helps minimise heat loss, absorb heat from the sun, keep your home warmer and reducing CO2 emissions


We are pleased to offer an exclusive 15 year performance guarantee on all Inliten profile and products, including white and foil laminate colours.

‘A’ Rating as Standard

Inliten products are thermally efficient by design; multichambers within the profile, combined with energy efficient glazing, reduces both heat loss and home heating bills. All Inliten double glazed casement windows achieve “A” ratings as standard.

Colour Options

Inliten products are fully sculptured, giving a shaped and curved appearance for extra character. Personalise your Inliten windows and doors with a traditional grain-effect foil, or a sleek and smooth spray-painted RAL colour finish.

0.8 U-Values

For maximum thermal efficiency, select our high-performance triple glazed windows. Featuring Soft Coat Xtra glass and Argon gas fill, Inliten triple glazed windows achieve whole window U-values as low as 0.8 W/m 2 K.
