About

MHB Steel Windows & Doors

With a history spanning 300 years, Dutch company MHB is pushing the boundaries of what’s possible in the design and manufacture of solid steel slimline windows and doors

MHB’s steel-framed windows and doors have a timeless appeal that combines stylish design with modern technologies. Innovations include a global patent for a thermal break that allows steel windows and doors to be designed with ultra slim profiles, creating more light, better visibility and endless possibilities for structural glazing projects.

Cotswold Windows is proud to be one of only three UK suppliers of these superior steel-framed windows and doors.

MHB Thermal Break

Patented Technology

01

MHB’s innovative thermal break

Thanks to centuries of experience in steel mastery, MHB has developed a unique solid steel profile that combines the exceptional strength of steel with a high-tech thermal break. The result is a strong, steel metal window frame with an ultra-thin profile and the sharpest contours on the market.

Its unprecedented performance only requires a width of 30mm and allows architects and home-owners the freedom to use the strength properties of solid steel in stylish home designs that are industry compliant.

Slim-Line Profile

MHB steel windows

MHB’s ultra-slim steel framed windows offer a new perspective on any type of glazing project. With the slimmest profile on the market, these steel metal windows allow more light to flood rooms with clearer views out.

Window panels are available in immense dimensions (up to 3.2m height / 3m²), and even larger steel frame windows can be custom-made to fit bigger apertures. Steel window designs include awning and hopper windows for opening above doorways, and tilt & turn windows for a minimalistic and multi-functional glazing solution. Steel pivot windows can be made bespoke to suit your requirements, all with unique, slim 50mm sightlines.

Maximum Visibility

MHB steel internal glazed screens

Steel framed glass partitions add strength and character to interior design projects. They allow light to flood into multiple rooms while creating a sense of divide between different areas.

MHB’s steel internal glazed screens and interior sliding glass doors are compliant with fire safety regulations and offer fall-through safety glass protection where needed. MHB’s steel internal glazed screens can also be offered with sound-proofing.

100+ years serviceable life span

01

MHB’s quality commitment

MHB’s steel windows and doors are designed to last – 100+ years to be exact! The frames are powder coated, plus extra protection is given with a Qualisteelcoat surface treatment to ensure they are fully weatherproofed.

Minimum upkeep is needed to prolong the lifespan of MHB’s steel frame windows and doors, thanks to the micro-engineered, double rubber seals and the use of a special wet seal for glazing.

STYLISH ACCESSORIES

01

Stainless steel hardware

The MHB steel hardware line offers the perfect finishing touch to any project. Door and window furniture can be used to reinforce a design concept and MHB’s high quality, solid stainless steel line of handles and escutcheons have the advantage of being interchangeable, bringing a degree of flexibility to the theme.

Designed to be durable and aesthetically pleasing, the fixing systems are cleverly concealed without the need for a separate cover plate. The steel handles and escutcheons can also be powder coated in any choice of colour.
