One of the UK’s most advanced IGU manufacturing lines

We’ve invested more than a million pounds in a new Forel Vertical IGU-Line at our Padiham IGU manufacturing facility.

Automatically applying the spacer bar to the edge of the glass sheet with an ultra-high level of accuracy, it achieves an instant and far better bond, than traditional spacer systems, maximizing thermal performance.

Combined with a highly accurate final seal on units, the next-generation process cuts the likelihood of IGU failure, which means you don’t get call backs!

Manufacturing an altogether better window

Combined with state-of-the-art window and systems from Profile 22 and AluK, we can offer you access to one of the UK’s leading energy efficient aluminium and PVC-U window and door ranges.

Casement Windows

We manufacture uPVC casement windows, fabricated in Optima, the energy-efficient next generation system from Profile 22; plus, the Optio 58BW ST aluminium window from AluK.

Flush Casement Windows

Choose from the contemporary or heritage, Optima uPVC Flush Casement window; or the AluK 58BW Flush Casement in aluminium.

Tilt-and-Turn Windows

We also manufacture the energy efficient Profile 22 Optima uPVC Tilt-and-Turn window and the AluK Optio 58BW aluminium Tilt-before-Turn window. Each is ideally suited to a wide range of commercial applications.

PLANITHERM® high performance glass is available in three different comfort levels:

ENERGY STANDARD – Keep residences warm and comfortable with Energy Standard glass. A superior choice for maintaining a cosy atmosphere while maximising energy efficiency.

COMFORT – Opt for Comfort glass to deliver enhanced security and serenity to homeowners.

COMFORT PLUS – The ideal balance of light, warmth, and comfort with Comfort Plus glass.


A special glass coating will stop heat escaping, so less energy is needed to keep a home warm. Energy Standard and Comfort glazing captures and makes use of the warmth from natural daylight, while Comfort Plus helps limit and control it – ideal for very sunny rooms.

Enhanced security: Comfort and Comfort Plus glass boast a high-security transparent layer, ensuring superior resistance to breakage. Compliant with the ‘Secured by Design’ standard, when used in an approved window frame, it enhances overall home security.

Our high-security transparent layer on Comfort and Comfort Plus glass makes them much tougher to break through than standard, unlaminated glass. Used in an approved window frame, they’re designed to meet the official police security initiative ‘Secured by Design’ standard, so you’ll feel safer and more secure in your home.

Noise reduction: Ideal for bedrooms and areas exposed to external disturbances, the built-in acoustic layer minimises exterior noise, promoting a peaceful atmosphere.

Furniture fade protection: Our hidden layer of protection on Comfort and Comfort Plus blocks out 99% of UV rays, safeguarding furniture and curtains from fading due to prolonged sun exposure.

Reduce overheating: Comfort Plus glass features a special coating to regulate heat from the sun’s rays, ensuring a comfortable and well-tempered living space, particularly suitable for sunlit rooms or larger glazed areas such as bi-fold and patio doors.
