Buy The “Ultimate” New Front Door

For a property to be suitably energy efficient it needs to have a front door installed that provides exceptional energy efficiency. So that householders can better recognise the standard of energy efficiency of a door when purchasing a replacement for their existing design, three years ago the government decided to establish Door Energy Ratings.

Similar to white electrical goods, replacement doors now each carry their own individual Door Energy Rating label, with an A-rated door being the most energy efficient available.

At Hazlemere we have a replacement composite door available that has rightly earned the title of the “Ultimate”, a door that offers the lowest level of heat loss in the double glazing industry.

For those who aren’t aware of what the word “composite” means the following is its online dictionary definition as a noun: “a complex material, such as wood or fiberglass, in which two or more distinct, structurally complementary substances, especially metals, ceramics, glasses, and polymers, combine to produce structural or functional properties not present in any individual component.”

Unfortunately, you need to be cautious when buying a replacement composite door as there are some poor quality imitations out there, usually being sold at a cheaper price than UPVC and aluminium double glazed replacement doors. However, our “Ultimate Composite Door” is widely acknowledged by many as the most advanced and thermally efficient and secure composite door in the UK and properly accredited and certificated so you know you’re getting the very best.

In addition to its superb energy efficiency, our Rockdoor Ultimate composite door similarly excels when it comes to security, carrying a security rating of 1, consisting of a carbon fibre reinforced inner-frame, German engineered multi point hook locks made from solid brass, cylinder guard protectors, a 6-pin cylinder Winkhaus lock option and a durable sash.

Because it’s protected by Heat Shield technology there’s no chance of the door ever cracking, bending or warping, and it’s low maintenance too, only requiring an occasional wipe down about once a year with warm soapy water.

For all-round performance you really can’t better the “Ultimate Composite Door”.
