HTL install and maintain automatic door systems to many applications, all our engineers are ADSA approved and installations are carried out to the requirements of BS7036. Activation can be by sensor, push pad or by controlled access where required
Customer access doors integrated with windows
Swing Doors – these can be fitted to many existing doors to make a door conform to DDA
Listed Building & unusual installations
An ancient door in a listed building (in this case Carmarthen University)
that required automating. No other company was prepared to quote. HTL supplied & installed and underfloor actuator that fully met the customer’s requirements. The result is almost entirely undetectable.
requirements where there may only be a low foot fall per annum. They can also be fitted to high use applications such as schools and be robust enough to stand up to constant activation day in day out. Sliding doors – allows good access control as long as there is space to the side of the structural opening for the door leaf to retract into. HTL have installed many sliding door packages to shops, motorway service areas, schools and hospitals with high foot fall with reliability and security being the top priority.
Bi-folding doors – used where there is a structural restriction on space, they offer a barrier free solution to many challenging areas.
Revolving doors – often used where there is a high volume of pedestrian traffic in and out of a building. Revolving doors have the advantage of keeping the internal temperature uniform, so making them relatively thermally efficient.
HTL fabricate and install curtain walling systems by Comar Aluminium and Kestrel Aluminium - for whom HTL are approved distributors. Curtain walling can be a load or non load bearing glass framed fašade to a building. When designing a curtain wall system consideration must be made to the thermal efficiency, the prevailing weather conditions hitting the building, the acoustic needs of the occupants and importantly the over all aesthetic look of the building in relation to what is around it.
Curtain wall systems can be plain or include opening lights as required. Glazing can be in glass or in solid panel dependant on the needs of the client.
Typical Kestrel Section
HTL offer a UK wide application of this type of glazing, if you require any further information please contact our office
Made from extruded aluminium alloy profiles to BS1474, with gaskets extruded from EPDM rubber.
Finishes are either anodised or powder coated, with the full range of RAL colours and gloss levels available.
Glazing - 3mm to 50mm glass units can be accommodated.
Effectively fitted secondary glazing units on the inside of any reasonably air tight outer windows will result in a considerable increase in the thermal performance of your building.
In addition there will be a significant improvement in the amount of sound insulation. However this depends on the gap between the glass in the outer window and that of the secondary. As a guide, a 50mm spacing will give an approximate reduction of 33 dB: a gap of 200mm will give an approximate reduction of 40dB. It is very important that an airtight fitting is achieved if thermal and sound insulation are required.
HTL manufactures and installs secondary glazing using its own profiles.
All secondary units are manufactured from extruded aluminium sections, and comply with BS1474 1987. Extrusions are bought in mill finish, and can be powder coated to any standard RAL colour as per BS6496. PVF2 coatings available to order.
In order to improve the performance of the units, all operating surfaces will be sealed to control aitflow. Horizontal sliding units use wool pile and sponge seal. Vertical sliding units use wool pile and extruded PVC on sashes and EPDM pressure seal on outer frame. Hinged and lift out units use woven pile
The profiles forming the outer frame and glazed panels are generally mitre cut and secured together with self-tapping screws.
The horizontal sliding windows are fitted with SGA rollers, which give a beautiful smooth and noiseless action. Vertical sliding panels are hung on adjustable spring balances and held closed with Fitch catches. Where a controlled opening is required for top or bottom hinged unit a telescopic friction arm is available.
Hinged and lift out units are held in place by spring/retaining clips, magnetic catches and/or turn buttons.
Units are dry glazed with SGA glazing gaskets providing a drive fit in recesses on the aluminium profile, which assembles around the glass. All glass used conforms to BS6262 for thickness and type (dependent on application)
Secondary glazing will not reduce condensation on the inside surface of the outer window, because humid air will filter through into the space between the two windows. Where condensation is a problem it is more effective to glazed the outer window with a sealed double glazed unit.
Many doors require an access control system - schools, offices, healthcare premises, government buildings to protect people and property. Also most commercial & public buildings require access control systems to comply with The Disability and the Equality Act 2010 and other pieces of legislation.
Every situation is different, and HTL can supply and install a system to suit the operational and budget requirements of the customer
The systems available range from basic manual/digital locks through to integrated video linked systems incorporating identity readers.
Once our surveyors and engineers know what security is needed they can supply and install a system to suit the application

Aluminium is a light weight, strong and plentiful material with a long pedigree in engineering. compared to other materials it has a long life span and minimal maintenance requirements. Modern techniques produce sections with excellent thermal qualities meeting all current environmental criteria where necessary.
HTL use Comar or Kestrel Aluminium sections: these can be fabricated in the full range of colours and finishes.
They are installed by our CITB accredited, factory trained teams who operate all over the UK.
Please contact our office on 01746 767401 to arrange to talk to one of our surveyors.
