Door Set Energy Ratings (DSER’s) were introduced on 1 September 2011 to the entrance door market, to provide a simple yet effective way of assessing the energy efficiency of residential external doors such as composite doors.
Rockdoor are the only composite door manufacturer to have an entire range of doors available with an A-Rating as standard. Your Rockdoor installed by South Lakes Windows Ltd will have an energy rating sticker attached to the door.
A-Ratings on composite doors are achieved using many innovative techniques, ensuring that heat loss is the lowest in the industry. The Rockdoor Ultimate Series features high performance low-emissivity soft coated glass which offers excellent thermal insulation when incorporated within a double glazed unit filled with argon gas and warm edge spacer bars.
Ultimate Series Doors
Featuring a 50mm thick door sash, argon filled double glazed unit, soft coat thermally efficient glass and a carbon fibre reinforced innerframe, Rockdoors Ultimate Series is available with an A-Rating (if chosen with clear backing glass) as standard -a first in the industry across a range – making it the most advanced thermally efficient and secure composite door available.
Energy Rating & Backing Glass
When choosing your Rockdoor Composite Door, we recommend choosing clear backing glass (the piece of glass on the double glazed unit behind the glass design) ensuring optimal thermal performance. This is because we can only use our Soft Coat thermally efficient glass on clear glass. When patterned backing glass is used, this reduces the energy rating as this style of obscure glass cannot use this technology.
However, even if your Door Set Energy Rating drops slightly, you can still feel confident that your Rockdoor will keep more heat in the house than other external composite doors on the market.
Additional Glass Designs
We are pleased to offer the following glass options to help you match certain property types or existing window patterns.
Georgian Bar Only available in Windsor, Jacobean, Kentucky, Portland & Stable View Light. Available in White, Light Oak & Woodgrain. Georgian Bar reduces the energy rating from an A to a B.
Surrounding Glass
If you are choosing glass for sideframes, fan lights or arches we recommend choosing Sandstone. Gluechip, Glacier, Woodland, Honeycomb or Misted Glass as these best suit our range of glass designs.
Obscure/Backing Glass
Choosing an obscure backing glass in replacement of clear glass will reduce the Door Energy Ratings – we recommend all designs featuring Gluechip glass are backed using clear glass to enable us to use Soft Coat glass. Alternatively if you would like a different backing glass, the following options are available.
Rockdoors are available in 12 different colours as shown. As Rockdoors are ‘made to order’, not ‘cut to size’, all colours shown are available inside & out.
Heat Shield

French doors make an excellent addition to any home. They provide clear and welcoming access into garden areas, and their clean panels help to bring light into the house, even in the grey days of winter.
French Doors – High Security
French doors are often considered a vulnerable point in a property, with burglars needing little more than a spade to break through and into your home.
With this in mind, Rockdoor focused hard on preventing unauthorised entry, and have developed what they believe to be the most secure French doors available.
Independent tests agree that Rockdoor french doors are secure, and have achieved PAS 23 and PAS 24 standards.
A carbon fibre reinforced inner frame gives solid fixings to all the locking components. One part of the door feature top and bottom bolts to securely fasten it to the outer frame, whilst the other has hooks to strongly fasten them together. Add the multiple hooks that join the two doors, and state-of-the-art hinges, and you’ve got a truly safe doorway.
French Doors Energy Efficiency
With heating costs rising yearly, it’s becoming more important than ever to pay attention to the energy efficiency of your home. With such large glass panels, French doors are clearly a cause for concern when it comes to energy savings.
That’s why Rockdoor used all of their resources to present you with French doors that truly live up to modern energy standards. The result is that Rockdoor uPVC-framed French doors achieve a Door Set energy rating of B. That’s better than a lot of solid front doors!
