Composite Doors vs. Other Types of Entry Doors
When choosing an entry door for your home, you may be considering other options besides composite doors. Let's explore how composite doors compare to other types of entry doors to help you make an informed decision.
Wooden doors are a popular choice for their natural beauty and timeless appeal. However, wooden doors require regular maintenance to keep them looking their best. They are susceptible to warping, rotting, and fading, especially in harsh weather conditions. In contrast, composite doors are incredibly durable and low maintenance, making them a practical choice for busy homeowners.
UPVC doors are another common option for entry doors. While uPVC doors are low maintenance and offer good insulation properties, they lack the aesthetic appeal of composite doors. Composite doors combine the benefits of both wood and uPVC, offering the warmth and beauty of wood with the durability and low maintenance of uPVC.

What are the Steps Involved in a Quality Inspection?
At Insight Quality Services, we conduct many inspections following a straightforward process:
Travel to the Facility and Pull Random Samples
The inspector travels to the factory and selects a random sample of products for inspection, typically following the AQL sampling method .
With the samples collected, the inspector goes through every item on your inspection checklist. This includes checking packaging and labeling, visual inspection, verifying physical requirements, and more.
Once all checklist items are reviewed, the inspector prepares an inspection report. This report includes a Pass or Fail result, photos, and any relevant notes about your products.
So, when should a shipment be inspected for quality? Most inspections take place after a production run is completed and before shipping. However, inspections can also be conducted before or during production, depending on your needs. In the sections below, we'll provide more detail.
As well as , we will also check
with customer if have any special inspection requirement and give customer direct insight or online inspection in details, to make sure the products are good quality before shipment.

How to Install a Composite front door step by step
Installing a composite door is usually a straightforward task that shouldn't require too much research or knowledge for our network of installers.
But sometimes it's good to refresh your memory, as when you're on the job, it can be quite easy to forget to carry out one of the smaller tasks.
We've put together this composite door installation guide to help installers in the middle of a job who need to refresh their memory before finishing a successful installation. It may also be of assistance when looking to adjust a composite door.

Maintenance
Installation of the composite door
Positioning of doorsets
When it comes to fitting a door, the placement of the frame within the aperture makes all the difference. The positioning of the new doorset should:
Bridge the cavity
Cover the damp proof course
Minimise exposure to the elements by setting as far back as possible in the aperture
Fixing distances
To determine the fixing spacings, the three sides of the frame should be secured in the following way:
Minimum of 150mm and a max of 250mm corner fixings distance from the external corner to prevent cracking welds
Mullion or transom fixings should not be closer than 150mm, or further than 250mm from the centre line of a mullion or transom
Intermediate fixings should be at centres no greater than 600mm
Must be a minimum of 3 fixings on each jamb
Using installation packers
To mitigate and prevent distortion to the outer frame during installation, installation packers of an appropriate size should be used, covering the full width of the outer frame profile.

The installation packers should not be able to compress or rot.
Ensure that the fixings are tight, holding the outer frame securely against the installation packers.
Tidying up
Following the completion of the installation, it is important to check that there is no debris or dirt leftover that could impact the operation of the door and its accessories.
Drainage channels should be checked to ensure that there are no obstructions, particularly from materials such as wet plaster.
Ensure that protective film is removed upon completion.
Note: Sand, cement, and plaster, should not be used to fill the gap from the frame to the structural opening.
Sealing the perimeter
In order to prevent water and air leakage, a perimeter sealant should always be applied. It's important that the sealant should be used to fill the entire gap between the aperture and the doorset.

Low modulus silicone sealant can be used to seal the gap.
Note: It is important to ensure that the sealant does not block any drainage channels. Always check that these are clear.
Adjusting the composite door
Sometimes the composite door may need adjusting, either immediately after installation or over time as movement occurs.
In this section, we'll take a look at how to adjust a composite door.
Hinge
Vertical adjustment of +4mm (5mm Allen Key)
Remove the end cap
To raise the door sash, rotate the vertical adjustment screw clockwise. Ensure that all other hinges are adjusted equally
To lower door sash, rotate the vertical adjustment screw anti-clockwise. Ensure that all other hinges are adjusted equally
Lateral adjustment +/-2mm (4mm Allen Key)
Rotate the lateral adjustment drives in the direction needed
Lock-off screw (2mm Allen Key)

For doors that open outwards, tighten the grub screw to lock the pin into position
Cylinder guard attachment
Slide the cylinder guard over the cylinder. To hold its position, tighten the internal screw
With a pencil, mark the position on the outside of the edge of the cylinder
Remove the internal screw and take the cylinder back out
Now position the outside cylinder guard against the pencil mark on the cylinder, then tighten grub screws evenly on each side with a 2mm allen key
Slide the cylinder back through lock and secure the other half of the guard
Ensure that all of the screws are tight to be effective.

Maintenance
After the composite door has been fitted, make sure the customer knows how to look after the door.
Door frame
It is important to clean the door every 4 months both internally and externally. This includes both sides of the door and the glass.
The best way of cleaning a composite door is with a soft cloth and hot, soapy water.
Outer frame seals
To ensure that wear and tear or damage to the outer frame seals hasn't taken place, it's important to take a look at them on a yearly basis.
If the seal is found to have shrunk or cracked, or tearing has been found, then the seal should be removed from the groove. A sharp implement, such as a knife, will do the trick.

Door hinges
Hinges should be checked yearly for any dirt or obstruction.
Coloured hinges should be cleaned using a soft cloth with hot, soapy water, rinsed with water and then dried off.
But if the hinges are aluminium or die-cast colour coated, it is important that these are not cleaned. They have self-lubricating nylon bushes, thus do not require any manual cleaning.
Locking mechanisms, handles, and letterplates
To maintain the locking mechanisms, handles, and letterplates, it's important to clean and remove dirt from moving parts on a yearly basis.
A light machine oil can be used on external moving parts.
For trickier dirt on the handles and letterplates, a mild detergent can be used. This should be rinsed off and dried after cleaning.

Threshold
The threshold should be checked regularly to ensure that there are no obstructions to the drainage holes. If obstructions are found, remove the obstruction and then flush with water to ensure the drainage holes are working adequately.
The weather seals should then be checked annually for any signs of damage, cracking, or shrinkage. If any cracking or shrinkage is discovered, the weather seal should be removed and replaced with a new one.

How to Properly Maintain and Care for Your Composite Door
To clean your composite door, mix a small amount of mild detergent with warm water and apply it to the door using a soft cloth or sponge. Gently wipe the door, paying extra attention to any areas that may be dirty or stained. Rinse the door thoroughly with clean water and dry it with a soft cloth.
Avoid using abrasive cleaners or solvents on your composite door, as these can damage the finish. Additionally, do not use sharp objects or abrasive materials to remove any dirt or debris from the door, as these can scratch the surface.
By taking these additional security measures, you can further enhance the security features of your composite door and protect your home and loved ones.

FAQS
Q: Can you fit a new composite door into an existing frame?
A: Although not compulsory, it's advisable to replace the frame at the same time as the door so that they have the same lifespan. It may cost you more in the long term if you need to replace the door or frame at separate points, risking damage to both parts. Modern composite doors also have updated locking systems that are continually improving. Changing the frame and door at once ensure that this will all align and work correctly.
Q: Are Composite doors hard to break into?
A: Composite doors are designed with security in mind and are manufactured by fusing together multiple materials under high pressure, producing a door that is both durable and secure (meaning that you get the twin benefits of a door that will last and deter intruders).
Q: Do composite doors warp in the heat?
A: Composite doors should not warp in the sun or heat. They are made up of layers of timber, laminate, uPVC and fibreglass providing a preventative measure against the issue of warping due to exposure to heat.
