A NEW

CONSTRUCTION HERO

HAS ARRIVED

A new construction hero has arrived to help you achieve energy efficiency without compromising on design.

In the bid to meet with building regulations, the most obvious energy efficiency solution is to add additional insulation or triple glazing. But did you know you can achieve significant fabric savings simply through your choice of lintel?

 

Supatherm lintels can improve the Dwelling Fabric Energy Efficiency (DFEE) by up to 3% and the overall Dwelling Emission rate (DER) by over 1%* (Based on a typical detached, semi-detached or terraced property)

 

Due to its unique production and assembly system, Supatherm provides an effective solution without impacting on complex designs such as apex windows or arches. 

 

• Over 75% reduction in heat loss compared to standard lintels

• Custom shapes, arches and various flange options on request

• Avoids propping associated with single leaf lintels

• Standard duty, heavy duty and extra heavy duty versions available

• All parts and assemblies CE marked to BS EN 845-2

 

CONSTRUCTION IS THE ART OF MAKING A MEANINGFUL WHOLE OUT OF MANY PARTS

SUPPORTING THE UK

CONSTRUCTION INDUSTRY

SINCE 1965

Founded in 1965 in County Durham, Birtley began life as a small structural steel business, opening on 19th July that year. Originally steel fabricators for the mining industry, Birtley added steel lintels to its product range in 1967 and by 1979 was a credible building industry specialist, with depots across the country. In 1996, Birtley commissioned and built a brand new plant, establishing one of Europes most advanced facilities for hot dipped galvanizing which remains fully operational today. 

Birtley acquired the metalwork manufacturer Expamet in 2012, followed by an acquisition of Bowater Doors in 2015. All three companies now operate under the Birtley Group banner, providing a broad spectrum of products to the construction industry.

UNDERSTATED

STRENGTH

Birtley is the only lintel manufacturer to hot-dip galvanize after fabrication providing up to 50% more zinc protection than other approved coatings. Hot Dip Galvanizing to EN1461 offers superior corrosion protection and lifespan compared with pre-galvanized steel. 

We offer a 65-150μm zinc coating thickness to suit life expectancy and exposure class. Our lintels are the only lintels to deliver consistent protection to all parts including welds and cuts, which are otherwise only protected by paint on pre-galvanized alternatives.

OUR COMMITMENT TO

QUALITY

With over 50 years of manufacturing expertise Birtley continues to be the stalwart of the lintel market, producing over 25,000 tonnes of steel products for the construction sector every single year. 

 

COATINGS COMPARED

Our post fabrication dipping process ensures that every part of every lintel is covered with an equally effective layer of protection. Other lintels are often made using pre-galvanized material, which is cut, bent and processed before a layer of paint is used to protect the cut surfaces, the same surfaces which are at the greatest risk of damage. Our cut edges are protected by metal, not paint, that’s why Birtley lintels are far more durable than other products on the market.

Within EN845-2, several material coatings are deemed suitable for use when manufacturing lintels for the UK market. The following scale diagrams show how we compare with other hEN approved systems of corrosion protection: 

BASIC

Paint only on cut edges

DUPLEX

Paint to all surfaces
