For when you need modern, secure, thermally efficient windows without sacrificing the heritage and character of your traditional or period property.
When you want to add the elegant Edwardian, Georgian or period feel to your fabulous new build.
This extremely versatile aluminium window system is an authentic and cost effective glazing solution with the aesthetics of traditional steel windows. Ideally suitable for a wide range of applications including heritage, listed, retro refurbishment and Art Deco projects.
With slim sight lines that create maximum glass areas the stepped frame profiles, glazing bar options and hardware choices offer a classic appearance with excellent thermal and operational performance.
With a range of dedicated system components Alitherm Heritage can be designed to easily accommodate external render and cladding finishes and can be effectively used as an appropriate alternative for contemporary applications that require slim sight lines
Exclusive to this system, Alitherm Heritage windows can be built as a series of individual modules to form a large multi part window coupled with a flush or feature drip bar.
A dedicated heritage door system and now NEW heritage bi-fold doors with matching frame profiles and exclusive hardware is also available to compliment this window range.
We had first class service from Marlin Windows. They are professional and efficient. We are delighted with our windows and would highly recommend them.
Inspired by the aesthetics of traditional steel windows, Alitherm Heritage features signature slim sightlines and attractive contours making it the ideal choice for heritage building conservation areas where building regulations demand a like-for-like replacement.
All main profiles feature polyamide thermal break technology that enhances the thermal performance of the product, allowing Alitherm Heritage windows to achieve a window energy rating ‘A’ grade when fabricated with the correct specification and glazed unit. Profiles have a high quality powder coated paint finish at Smart’s state of the art paint facility in a choice of finishes, including single or dual colour, in a range of standard and non-standard colours.

Marlin Windows were reassuringly professional, calm & helpful from first contact which made the decision to use them so right. The pre-sales team were full of advice - not in the least bit pushy contrary to stereotype - & the advice was spot-on because they'd done it all before.
The product looks amazing too... I suppose the windows might be much the same elsewhere & maybe even of similar price or cheaper, but the customer support, reliability, professionalism & interest at Marlin is second to none.
I honestly think it's a rarity these days to come across a company with values like Marlin so 5*s well-deserved.
