Are Oak doors solid Oak?
All XL internal Oak doors are of engineered construction. Benefits of engineered over solid Oak:
- Less susceptible to movement than solid Oak doors
- Better colour match as all door components are veneered
- Better utilisation of timber = better for the environment, less wastage
- More resistant to environmental fluctuations, e.g. cold and cold rooms during winter heating cycles.
What is the difference between a door with Dowelled construction to that of a door with M&T construction?
Our Dowelled Hardwood doors are manufactured from kiln dried timber and are jointed using fluted dowels and modern adhesives.
Our Mortice & Tenon doors are manufactured from select kiln dried hardwoods, and are constructed using traditional Mortice & Tenon joints and modern adhesives. This ensures that the doors are constructed to the very highest standard. The panels are set in waterproof mastic ensuring that the highest level of weatherproofing is achieved.
How much timber can be taken off an Internal door?
When trimming an internal door to fit, it may be reduced by a maximum of 12mm in both width and height: The reductions must be split equally from each edge, i.e. to reduce the door width by 12mm, remove 6mm from each side of the door.
How much timber can be taken off an External door?
When trimming a door to fit, the door may be reduced by a Maximum of 12mm off each side, top and bottom. Any reductions must be removed equally from each edge.
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/lacquer should be used.
I have broken a piece of glass, can you supply a replacement piece? (applies to all internal doors XL Joinery supply)
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).
The glazing bars on my doors are out of line, not square, what can I do?
The vertical glazing bars can be tapped back into line, these are dry set into the door and could move in transit.
What is the thickness of the glass in XL's doors?
Flat Glass: 4mm approx
Bevelled Glass: 6mm approx
Double Glazed: 14mm approx
Tripled Glazed: 18mm approx
What if I receive an obscure glazed door and it has clear patches on the glass?
This effect is usually caused by a substance "filling in" the glass etching and turning it almost transparent, usually caused by silicone. It can be removed with white sprits and vigorous rubbing of the transparent patch. Once the white sprit as been applied, leave to dry and the glass should become obscured again.
Can the internal Oak door pair lining set be used on any other size of doors?
The length of the lining and door stop is 2134mm long x 20mm thick, 3 lengths of each. If you give the customer these sizes, they can work out the dimensions they need to cut the lining & door stop to. The lining is designed to be used for up to 60" pairs.
Is the glass in the glazed doors toughened safety glass?
Yes all glass in our glazed doors is toughened to BS6206(A) or BS EN 12150 safety standards.
What is an Intumescent Strip
An intumescent strip is a component for a Fire Door. It is placed around the door frame and is chemically designed to automatically expand when exposed to extreme heat, thus sealing the gap around the frame. This therefore contains the fire and allowing for enough time to escape.
This is very important as isolates the fire to one particular area and helps to protect people whilst also minimises damage to the building itself.
It differs from a smoke seal as that is used to block smoke and not contain a fire. We offer a range of options for our internal fire doorkits.
What is a Smoke Seal
A Smoke Seal is basically a barrier on fire doors that prevent the flow of deadly and hazardous fumes travelling form room to room. It works by being placed between the door frame and the door on all sides. By preventing smoke passing through the gaps between the door and frame, allowing more time to escape as the rest of the building is not affected by heavy smoke.
It is important to have a Smoke Seal as inhalation of smoke kills more people than fires do! An is an effective but easy means of preventing this from happening.
A smoke seal works differntly from an intumescent strip, as it prevent the smoke spreading whereas a intumescent strip blocks off the fire itself.
