Sheerline hits TV screens

Sheerline’s innovative aluminium window and door system is appearing in a popular home improvement TV programme.

The newest episode of George Clarke’s Old House, New Home features homeowner Leighla Davenport and her Grade II listed home, Callowell House, nestled in Stroud’s idyllic countryside.

The refurbishment project saw the construction of a modern extension that was integrated in a meaningful way with the rest of the property. Sheerline, with its slim sightlines and perfectly mitred corners, was a sympathetic enhancement to the original building.

Leighla’s newly-refurbished home features a mix of Sheerline products, including 12 Sheerline Classic windows in cream with Sheerline Prestige fixed frames in black, and two Sheerline Prestige doors, also in cream.

Leighla says: “I found Sheerline through internet research of premium aluminium systems companies and I thought that it was a really nice product. We needed some unusual glazing and Sheerline had the capacity to do all of the windows we required. At a time where lead times were anything but normal, Sheerline offered the shortest delivery times, meaning we could keep the project on track.

“We have a Grade II listed building and Sheerline, and the Classic beadless range with its slim sightlines in particular, works across the entire building – both in our 150-year-old mullion windows and in our new extension – it’s so versatile and really brings in light. It’s high performance, maintaining modern functionality as well as being in keeping with the look and feel of our home. Plus, the low U-Values mean we don’t have to compromise between energy efficiency and the way it looks.

“A huge selling point for me was the fact that Sheerline is Made in Britain, and all the benefits that brings. There aren’t many companies investing in manufacturing in the UK, and it’s really great to see that happening in Derbyshire.”

The episode of George Clarke’s Old House, New Home featuring Sheerline will be broadcast on 10th November at 8pm on Channel 4.

Roger Hartshorn, CEO of Garnalex, says: “We were delighted to be involved in such a significant project and were pleased to see just how well Sheerline integrated in Leighla’s home, offering top-level thermal performance and faultless aesthetics, while remaining in keeping with the rest of the building.

“The agility of Sheerline’s supply chain meant that we could offer dual colours in just a fraction of the time that our competitors were offering, ensuring that the project remained on schedule. The customer was pleased with the support and service she received from our passionate team – one of our team even visited the property to help with the fitting of the windows and doors.”

Express Trade Frames says Sheerline is ‘ahead of the market’

Express Trade Frames (ETF) is one of the latest fabricators to manufacture Sheerline, the innovative aluminium window and door system from Garnalex.

Managing Director Scott Law says: “We knew Sheerline was going to be a great system and we wanted to get on board and grow with them as they grow. It’s ahead of the market. We’d followed Roger Hartshorn’s success at Liniar and wanted to be part of it.

“For us, the speed and ease of fabrication is important, and Sheerline really delivers. The market is asking for lower U-Values, especially on new build sites to meet tighter building requirements, and this is easily achieved with Sheerline. We fabricate the flush sash option as standard and it’s beautiful with low sightlines. The feedback we’ve had from installers has been really positive, they say it’s easy to install and glaze up.”

Based in Fleetwood, Lancashire for 22 years, ETF has been fabricating aluminium for just three, but aluminium has grown so fast it now exceeds its PVC-U sales. It’s grown fast because of its sustainability credentials, colour choice and slim sightlines.

Scott adds: “The market has responded very well to Sheerline and we’ve already picked up several commercial contracts on the back of sending out samples. As delivery times from Garnalex are so quick – within five working days – we’ve been able to reduce our stock levels. The support and service from the Sheerline team has been faultless, they have sorted any queries we’ve had quickly and easily.”

Roger Hartshorn, CEO of Garnalex, says: “We’re delighted to have Express Trade Frames as one of our Sheerline partners. And we’re particularly pleased that Scott refers to our quick delivery service and ‘faultless service and support’. One of my objectives from the very start was to build Garnalex’ service and support around customers’ need to provide their customers with first class service and support. That’s why its ‘Made in Britain’ here in Derby, and why we keep all our profiles and components in stock. That gives us complete control over our short supply chain and enables us to offer the shortest lead times in aluminium. Customers get delivery of Sheerline profiles in 12 stocked colours in just five working days, or – for normal aluminium – an amazing 10 working days for bespoke colours. Not only is Sheerline ahead of the market in innovative design, it’s beautiful, and it’s ahead of the market in terms of service and support too.”

Sheerline’s new trailblazing Prestige aluminium bi-fold

Sheerline has launched a new range of bi-fold doors, which extends its popular range of Sheerline Prestige aluminium windows and doors.

The new Sheerline Prestige bi-fold combines style, security, innovation and sustainability in a ground-breaking range of bi-fold doors.

Future proofed against the proposed tightening of Part L of the Building Regulations, the bi-fold achieves extremely low U-Values – 1.4 W/m²K double glazed and 1.0 W/m²K tripled glazed. It features Sheerline’s multi-chambered Thermlock® technology, which ensures greater thermal performance compared to other aluminium bi-folds that use polyamide thermal breaks.

With four different threshold options, including one with an integrated cill, all featuring fully weather-sealed rebates, it offers up to seven pane configurations. With both inward and outward opening options, the bifold has a maximum height of 2.6m and a maximum width of 6.5m.

Bespoke hardware, based on proven ‘tried and tested’ designs is supplied by VBH, with a custom-made Winkhaus ‘Thunderbolt’ lock. Brisant-Secure’s Ultion 1* Plus 2* lock and handle combination is also available, offering 3 star protection, as well as a unique folding Ultion key, that protects frames from damage.

A one-piece stainless-steel track with integral drainage allows for controlled, reliable rolling, and tri-material Garnalex gaskets with low friction coatings ensure smooth operation.

The ancillaries used on the bi-fold doors are the same as for the standard Sheerline Prestige window and door system, allowing for simplified stock holding. Fabricators also save time and money using the same milling cutter as the rest of the Sheerline Prestige range.

Clip in beads are used on the Prestige bi-fold allowing for quicker, easier installation. The integral cill and ramped low threshold options also feature unique, one-piece end caps which act as frame jointers, saving time, and incorporating concealed drainage. Outer frames can also be supplied to installers as a flat pack, to make onsite assembly easy.

Roger Hartshorn, Garnalex CEO, says: “Aluminium is the ideal material for bi-fold doors as it’s inherently strong and looks fantastic. Our technical experts injected innovation at every level, and because we started from a clean slate, we avoided legacy design restrictions.  

“We listened to our fabricator partners and then we designed a bi-fold to exceed their expectations and wow installers and homeowners. And because we make every major part here in Britain, our carbon footprint is reduced and because we supply our standard range of colours from stock, and bespoke colours are made on site, the Prestige bi-fold is available in our standard range of 12 stocked colours within 10 working days, with bespoke colours in just 15 working days. That’s also pretty remarkable for aluminium.”

Nordic Aluminium: Sheerline is ‘streets ahead of the competition’

Manufacturer Nordic Aluminium says Sheerline’s aluminium window and door system will change the market.

Nordic Aluminium is a division of the HWL Windows Group, which has been operating for almost 20 years. The company wanted to apply its experience and knowledge of selling high-value PVC-U windows to an aluminium window and door system packed with unique benefits for customers.

Graham Howatson, Director, Nordic Aluminium, says: “Windows are becoming more of a ‘boutique’ product and many homeowners want something different than standard PVC windows. We were blown away by Sheerline and think it will have a similar impact on the aluminium window market as Residence Collection had on the PVC sector. We were interested in the simplicity of the system design, the added value it brings to homeowners as well as its innovation and availability of stock. Sheerline will change the market, without a doubt.

“Sheerline’s product innovation is streets ahead of the competition. It’s easier to manufacture, has improved material optimisation due to the design of the assembled profile, and its choice of colours will allow retailers and installers to simplify their product offerings and have greater control over the whole process. The U-Value performance is a huge factor as well. Sheerline exceeds current building regulations and is future proofed against planned changes.

“Sheerline’s design is clever, with fewer components and lower stock holding requirements. The patented thermal breaks are of major benefit and will eventually lead to the roll-out of our own material, resulting in better optimisation and improved availability. The choice of standard colours has also been well thought out – we have found that Agate is a really popular finish, so it’s great to have that as a standard colour option.

“Customer support always seems to be at the forefront of Garnalex’ thoughts. They go above and beyond and really see the importance of building long-standing relationships.”

Founded in 2018, Garnalex’ innovative system Sheerline is the result of the company’s mission to revolutionise the aluminium windows and doors market. Sheerline’s first system, Classic, is an ultra-secure beadless aluminium window system packed with exceptional features that bring real benefits to fabricators, installers and homeowners. Its second system, Prestige, is Sheerline’s most versatile and thermally-efficient system with window U-Values as low as 0.9 W/(m²K) for triple glazing and 1.3 W/(m²K) for double glazed and includes single and French doors.

Roger Hartshorn, CEO of Garnalex, says: “We’re delighted to have such a fantastic response from a respected company like Nordic Aluminium. And I’m really pleased when customers say that we’re achieving what we set out to do – to transform the aluminium windows and doors market. Each step of the process, from product design to service and support, has been reinvented with fabricators, installers and, of course, the homeowner in mind. We’ve invested in innovation at every level to ensure customers receive the end-to-end experience they want and deserve.”

Huge buzz in the industry around Sheerline says Belvedere Products

South West manufacturer Belvedere Products believes the thought process behind Sheerline, Garnalex’ innovative aluminium window and door system, really sets it apart from competitors.

Russell Jones, Director of Belvedere Products, learned about Sheerline through word of mouth more than two years ago and wanted Belvedere to be involved from the beginning.

Russell says: “Demand for aluminium windows is definitely growing. The sleek look and large areas of glass that aluminium offers is very popular. I call it the ‘Grand Designs’ effect. There’s a huge buzz around Sheerline in the industry, with a great deal of anticipation. As the product range comes to market, the expectations are high and I don’t think they will disappoint.

“For me, the thought process in the product development sets it apart from other systems. The Classic system, in particular, is a thing of beauty. My initial thoughts were how slim the profile is, making it an impressive-looking window. The innovation behind the beadless system to achieve this is ahead of its time. Our experience of fabrication has been good so far and the fast delivery times enable us to offer the quick turnaround our customers are used to. Support and service from Garnalex has also been excellent.”

Russell continues: “There are a number of clever features in Sheerline that seem simple yet have not been addressed previously. The compatibility of the ancillaries is a big positive, as are the thermal breaks. We are still in a very early stage, but we’re confident Classic and Prestige products will slot into our established range perfectly. Sheerline is bringing aluminium up to date in a well thought out and integrated manner. We’re all excited about the journey.”

Sheerline was born out of Garnalex’ mission to reinvent aluminium windows and doors. Designed from the ground up by a team of technical experts, the innovative system is easy to fabricate, simple to install and a dream to sell.

Roger Hartshorn, CEO of Garnalex, says: “We’re extremely pleased to have Belvedere Products with us on our journey of growth and development. Our innovative system has been built with the end user in mind, and we’ve transformed the experience of fabricating and installing aluminium windows for fabricators and installers by designing a product that’s easy and quick to manufacture and install.

“We design and make every component here in Britain, meaning that we have full control over the supply chain. We keep all profiles in 12 stocked colours, including our new gloss finish HIPCA White, in our large bespoke warehouse, which transforms delivery times. We deliver profiles to customers in just five working days.”

Sheerline adds new gloss HIPCA White to stocked range

In response to customer demand, Garnalex has introduced a new gloss finish, HIPCA White, to its range of stocked colours for Sheerline windows and doors.

HIPCA White, RAL 9910 is an additional white option, alongside the existing Pure White, RAL 9010, bringing the total stocked colours for Sheerline’s colour range to 12. The new coating will be the first of Sheerline’s range to be available in a gloss finish.

The innovative Sheerline aluminium window and door system is transforming the residential aluminium market since the introduction of its first system, Classic, last year. Designed from the ground up, Classic is an ultra-secure beadless aluminium window system which combines exceptional performance with refined aesthetics. Earlier this year, it was joined by Prestige, Sheerline’s most versatile and thermally-efficient system. Prestige features window U-values as low as 0.9 W/(m²K) for triple glazing and 1.3 U-value W/(m²K) for double glazed and includes single and French doors with a wide range of outer frames and styles for near unlimited choice.

The new gloss HIPCA White will be available on all Sheerline’s profiles with matching ancillaries.

Sheerline’s range of 12 stock colours includes three anodised colours for the ultimate durable and stylish finish. Sheerline keeps all profiles, in all 12 colours, in stock at its own warehouse in Derbyshire, meaning that orders are not at risk of long delays at sea or in the docks and can be delivered to window manufacturers in just five working days. Bespoke orders are also available in just 10 working days.

Roger Hartshorn, CEO of Garnalex, says: “Our new white gloss was a direct result of customers telling us what they wanted from an aluminium system. All of our components are made by us, here in Britain, which means that we have full control of the supply chain and we keep all profiles, in 12 stocked colours, in our large warehouse. We offer very short lead times, just five days, to fabricators, so they, and their installer customers, can keep up with increasing demand from homeowners. This is revolutionary in the aluminium sector.”

Sheerline launches ‘next generation’ S1 roof lantern

Sheerline continues to expand its impressive range of innovative aluminium products with the launch of a next generation aluminium roof lantern. It combines sleek low-level styling and cutting-edge performance to create one of the most secure, thermally efficient and beautiful lanterns on the market.

The S1 roof lantern has been designed from scratch by Garnalex’ expert team, and the end result is ground-breaking. S1 is not only ultra-secure and energy efficient but stylish and modern, compared to clunky traditional systems. Available in three stocked colours across 10 different styles, with two and four-way options and designed around 28mm glazing, this advanced roof lantern has the options to suit any project.

Sheerline’s S1 redefines the product category’s security expectations, often a weak point in lantern roofs, with a number of unique innovations. Overlapping cast end caps prevent the bar and top caps from being removed and anti-tamper screws are provided to attach end caps to roof bars. High-security 2 and 4 way top caps are also bolted through from the inside preventing easy removal. The arrangement of the interlocking eaves beam means that the glass cannot be removed from the outside and features a unique patent pending glass lock, lowering the risk of break-ins even further.

Designed with the same innovative Thermlock® multi-chambered thermal breaks as the Classic and Prestige systems, the S1 roof lantern offers maximum thermal performance throughout its design, from the eaves beam and ridge to each rafter assembly. Cold bridging is prevented by ensuring the aluminium is fully encapsulated below the glass line with a unique co-extruded perimeter seal creating a weathertight seal for enhanced performance and energy efficiency.

Slim, consistent 50mm rafter, hip and ridge sightlines maximise light flooding into homes, creating bright, airy interiors and banishing gloom. The S1 lantern also features ultra low line aesthetics, so rafter and hip top caps sit just 8mm above the glazing level on the exterior, creating a sleek modern look. Completing this refined architectural appearance, corner and rafter end caps run perfectly in line with its perimeter, so no unsightly angles jut out to spoil the perfect lines of this beautiful high-performance aluminium lantern. It creates the ideal balance of understated refinement, contemporary looks and exacting quality standards.

Roger Hartshorn, CEO of Garnalex, says: “We expect the S1 roof lantern to transform the aluminium roof lantern market, much like Classic and Prestige have done for aluminium windows and doors. Not only is it beautiful, but it also tackles some of the security issues that customers face with existing products. Our team of experts have reinvented aluminium roof lanterns into something that is ultra-secure and thermally efficient as well as being stylish and contemporary. The latest addition to the Sheerline family is fabricator friendly and offers easy, trouble-free installation. And it’s available on short, reliable lead times.”

Sheerline is ‘a breath of fresh air’ for Whiteline Manufacturing

Whiteline Manufacturing Ltd, established in 1984, was one of the first leading fabricators to manufacture Sheerline’s ground-breaking aluminium windows and doors.

Steve Milham, Whiteline Manufacturing CEO, comments: “The Sheerline system is new, innovative, British, thermally efficient, clean and extremely versatile. It’s hard to think of a reason not to buy it! For those of us that have been in the industry for as long as I have, Sheerline is a breath of fresh air.”

“Delivery times are unheard of for this product type and this means faster reaction times to clients’ needs and consequently, the ability to convert more orders. Initial discussions with our customers have been extremely positive and samples are being requested on a frequent basis, so early signs are very encouraging.

“Demand for Aluminium has been growing in recent years and our own aluminium division has increased tenfold over the last few years. With so much PVC-U in circulation, it is of no surprise that aluminium products are constantly growing in volume.”

Garnalex CEO, Roger Hartshorn, adds: “The feedback from Steve is just what we hoped for from Sheerline launch partners. Steve’s right, demand for aluminium is growing as homeowners look to make sustainable and beautiful improvements to their homes, and we want our partners to be able to supply this demand quickly and easily. Every major component of a Sheerline window or door is made by us here in Britain. Our aluminium profile is available in 12 stocked colours in just 5 working days and bespoke colours in just 10 days. Keeping all these colours, in all the profiles, in stock in our large warehouse changes everything.”

With a mission to reinvent aluminium with systems that are easy to fabricate, easy to install, look beautiful and are a dream to sell, Garnalex has designed Sheerline from the ground up. Sheerline’s first system, Classic, is an ultra-secure beadless aluminium window system packed with unique features that bring real benefits to fabricators, installers, and homeowners. Meanwhile, Sheerline Prestige is the company’s most versatile and thermally efficient system, with DG U-values of 1.3, TG of 0.9, which includes single and French doors with a choice of outer frames and styles for unlimited design options.
