Security is a key consideration when choosing bifold doors. Here, we answer some of the most common questions homeowners ask about aluminium bifold door security and performance.
Bifold doors add a sense of luxury and look stunning. Bifolding doors enable you to really open up your home, perfect for a wider conservatory or rear extension entrance because they concertina back on themselves, using minimal space when open. Flexibility and usability are key features of bifold doors. You can have them fully open, fully closed or anywhere in between. When they are closed you get the same warmth, noise-reduction and security provided by all aluminium framed doors. Bifolding doors can open left to right, or right to left and are available with options for glazing, colour, hardware and security to suit your requirements.
Secured By Design is a police security organisation that works with police forces to deliver a range of crime prevention initiatives to make homes more secure. Working alongside the Police Service in the UK, Secured By Design aims to achieve sustainable reductions in crime through design and other approaches. Today, products like doors and windows have to be certified by a UK Accreditation Service (UKAS) certification body before being considered for SBD’s Police Preferred Specification. Excellent Doors offers a range of doors that have achieved this accreditation.
Energy Efficient glass is used in double glazing and triple glazing to help reduce heating bills and improve the carbon footprint. Most new builds will be fitted with energy efficient doors and windows. Owners of older properties are advised to replace any single or old style double-glazing with new energy efficient glass. Unlike single glazing, new energy efficient glass included coated (low-emissivity) glass to stop heat escaping through windows and doors. It offers highly beneficial thermally insulating properties to keep cold out and warmth in. Double glazed windows will have 2 sheets of energy efficient glass with a gap in between of about 16mm. Triple glazing has 3 sheets of glass. The gaps in between forms an insulating barrier and is sometimes filled with gas. Energy efficient glass not only helps to reduce heating bills by making rooms cosier with less draughts, but it also reduces external noise, make your home a more peaceful place to be.
If you are looking for the ultimate in security, a steel door is stronger than wood, upvc or composite doors. Aluminium doors have also become increasingly popular in recent years and offer a high level of security and come with reinforced glass. Bifold doors are very secure and have multi-point locking mechanisms which are operated on the inside. Sliding doors have multi-point locking mechanisms vertically up and down for maximum strength and upvc doors can have anti-snap locks fitted as well as dead bolts for increased security.
The natural strength of aluminium provides enhanced security for your home. The aluminium doors in the Excellent Doors range all feature multi-point locking mechanisms as standard and hold the prestigious BSI Kitemark, a worldwide trusted symbol of quality. Aluminium doors are stronger and more durable than uPVC and have the added advantage of being corrosion free. Because aluminium frames are so strong, skilled craftsmen can create a narrow profile bifold and sliding doors that allow the maximum amount of natural light to flood into a room. This results in a door that is strong, secure and stylishly attractive, combining slim sight lines and elegant styling.

Margaret MoonTrustindex verifies that the original source of the review is Google. We have used Excellent Windows over a number of years and now the whole house has been done. No high pressure sales. Very good quality products and reasonable prices. Delighted with the service and the people fitting the windows are always pleasant, do a good job and tidy up. andrew corringhamTrustindex verifies that the original source of the review is Google. Long overdue, I finally decided to get replacement windows for the rest of the house. We had use Excellent Windows to replace a French door several years ago, and considering the French doors still look and feel like new, i thought of Excellent windows straight away. I used the websites quick quote option to get a rough idea of cost - this gave me options to select the style and openings i wanted and provide a rough quote. Shortly afterwards, Michael reached out and offered a free home visit to provide a more accurate quote. From getting the quote and agreeing to proceed, Michael arranged a second home visit to get full measurements for the windows to be made, and 7 weeks (including the Christmas period) later they were here to fit them. Wayne and Michael lived up to the company name and did an excellent job, really considerate of the property and cleaned up as they went along. The windows all look great and the finish is perfect. After a week with the new windows we can really notice the difference in how warm the house feels and how quiet the house is, not being able to hear the cars on the main road. Hilary ScogginsTrustindex verifies that the original source of the review is Google. I am really, really pleased with the bifold doors and conservatory I recently had fitted - looks stunning! From start to finish it was a pleasure dealing with this company. Michael supplied exactly what I wanted ( no heavy salesman talk) and he has a great team of guys who worked efficiently and professionally - all with smiles and happy banter! Thoroughly recommend them. SarahTrustindex verifies that the original source of the review is Google. My new windows and doors have totally transformed my home.

Happy to recommend 😎👍🏻 Steve LambdenTrustindex verifies that the original source of the review is Google. After having the whole house transformed with all windows and doors, I would like to thank the team, Michael the owner, Wayne and Ross the two fitters, I am extremely pleased with the works completed last week, a very high standard of workmanship from people that care about their customers, I believe they run by the mantra that the customer is at the heart of what they do, nothing is too much trouble, I have had more work estimated for my daughter and will be looking to get my garage and soffits done in the near future, I would highly recommend this company. C SmithTrustindex verifies that the original source of the review is Google. Recently called Michael about a problem with our front door not shutting properly. As usual he promptly returned my call and within days got the problem sorted out. He is a very reliable and honest man and we are so pleased that we used his company to install all our windows and the door. We would fully recommend Excellent Windows.Google rating score: 4.3 of 5, based on 24 reviews
