Q1. Do I need to reduce my door to suit the opening I have, how much can I take off the door?
On external doors we recommend that no more than 12mm be removed from any side, top or bottom. Sometimes door openings are a non standard size e.g. 31 1/2″ x 78″.
We would advise that you purchase an 80″ x 32″ door and reduce the height rather than the width, as there is more width to the bottom rail than the door stiles. However removing more than 1″ from either the height or width will invalidate the guarantee.
Q2. I have broken a piece of glass, can you supply a replacement piece?
These doors are of cassette construction therefore they are built around the glass and there are no loose beads. We do not have replacement glass. If the customer wants to re-glaze, they would need to router the mould off one side of the glazing aperture, remove the broken glass, put new glass in and acquire a new loose beading to re-glaze the door ( probably as cheap to buy a new door).
Q3. The label on the door states that I cannot use wax, teak oil or varnish. Why not?
When we manufacture a door it has a controlled moisture content, the above mentioned treatments will not seal the moisture content into the door, therefore allowing moisture ingress or loss to occur causing the door to either swell or shrink. Only a fully paint finish (primer, undercoat, gloss) or high performance wood stain should be used.
Q4. What is the U-Value of a specific external door?
Certified U-Values are available for the majority of Best4Doors Doorsets. These U-Values have been determined by Chiltern Dynamics, an independent UKAS accredited testing laboratory. External doors sold separately are available with indicative U-Values only. These indicative U-Values are based upon information from BRE 443 2006 Edition: Conventions for U-Value Calculations, produced by the Building Research Establishment Limited.
Q5. The glazing bars on my doors are out of line, not square, what can I do?
The vertical and horizontal glazing bars can be tapped back into position. If the customer does not want to attempt this and is not happy they need to raise a complaint with the store where they purchased the door from and we will send an inspector to look at the problem.
The glazing bars are usually out of line due to the movement in transit.
Q6. Can you tell what the fire rating is for my door?
Other than the specific fire doors sold by Best 4 Doors, none of our internal or external doors have a fire rating.
The fire doors sold by Best 4 Doors all have a 1/2 hour fire rating.
