Can I choose the colour or finish of the doors?
Yes, we offer white, black and anthracite grey as our standard colour options. After that there over 200 RAL colours to choose from, as well as dual colour options, woodgrain finishes and structured finishes. Choosing non-standard colours or finishes could extend lead times, and we will always inform you if this is the case.
Does pcw offer bifolding doors with built-in blinds?
Yes, our double glazed bi-folding doors can be fitted with integral blinds.
Are the doors opening inwards or outwards?
We offer bespoke, and made to order door that can be custom designed. The front doors in general open inwards to invite people in. However when the entry doors are being fitted at the back of the property in general they open outwards.
Can you match existing design of other windows?
Whether you need to change only one window and want to keep exactly the same design (with all the decorative features or designs like bars or leaded designs). It does depend on the material you require e.g timber, uPVC or Aluminium, but all our products are custom made to order and specifications and manufactured in our Park Royal factory. For further information please contact us and we can examine your exact requirements and then advise accordingly.
What colours are your aluminium doors available in?
All of our doors are available in a wide range of RAL colours, allowing you to match the colour to that of your home’s decor. Our dual colour options allow for choosing one colour for the inside and another for the outside. We have our standard colour range, such as white, black and anthracite grey to pretty much any other colour you can think of, you can have true control over the colour of your doors. Choosing non-standard colours or finishes could extend lead times, and we will always inform you if this is the case.
Do 26 slim sliding doors come with blinds?
Due to the specification of the 26 slim sliding door product the range does not come with the option of in-glazed blinds.

How secure are your doors?
Multi point locking comes as standard, in our windows and doors, on all of the opening leaves. All glazing is internally beaded increasing the resistance to forced entry.
Will you make matching windows and doors?
Yes. Some of our product ranges allow this. For further information please contact us.
What are the types of glass you offer?
All units are double glazed and where required they can be supplied as toughened, laminated or with security glass. You can also further choose the argon gas filled for improved insulation, colour tint, special finishes, triple glazing or secondary glazing. For further information please contact us and we can examine your exact requirements and then advise accordingly.
How do I maintain the paint finish on my windows and doors?
Please visit our website page for detailed information on product maintenance.
What is a U-value?
The U-value (or U-factor), more correctly called the overall heat transfer coefficient, describes how well a building element conducts heat (in our case the frames and glass of our doors and windows). It measures the rate of heat transfer through a building element over a given area, under standardised conditions. A smaller U-value is better at reducing heat transfer. To comply with building regulations on a new build a window must achieve a U value of 2.0 W/m2K and in an extension or alteration 1.6 W/m2K. A door has to achieve a U value of 2.0 W/m2K in a new build and 1.8 W/m2K in an extension or alteration. The only other way to pass building regulations for insulating for a window only (does not apply to doors) is to have a BFRC (British Fenestration Rating Council) energy rating of A-C.
What are the trickle vents?
Every building requires some sort of ventilation and it is a building regulation requirement to provide a certain level of background ventilation in certain rooms or areas within your home. Background ventilation can be achieved through small slot vents which are placed in the head of our frames. The amount of ventilation required would be determined by the type of room and whether it was in a new build or an extension/alteration. Trickle vents aren’t the only method of providing this ventilation, this can also be achieved through heat recovery systems, air bricks or vents placed in the fabric of the building. For further information please contact one of our team who will be able to advise.
When do I place the order?
There’s no rush, we won’t push you towards a sale until you’re absolutely ready and have all the information and advice you need. If you are completing building work you need to ensure you factor in our lead times to make sure your doors or windows arrive on site last, when the building site is ready for their installation. Our team can provide you with our current product lead times on request.
Are your glazing products energy-efficient?
Yes. Double and Triple Glazing products are known for their ability to improve household energy efficiency when compared with traditional windows. We use the latest industry compliant glazing products including the most energy-efficient products, we can supply windows with energy efficiency ratings from A-C. We normally recommend going for an A-rated window to maximise the energy efficiency savings, but we are happy to work to your energy efficiency requirements.

Do I need planning permission for a conservatory?
It depends. If your property is not already extended on the ground floor and you opt to have a conservatory that extends no more than 3m from the back of your house you may not require planning permission. If this applies you can build the conservatory as “permitted development”. We would however advise you seek confirmation from your local planning office.
