The Home Dry Positive Input Ventilation unit (or “PIV unit”) uses air displacement to ventilate a whole dwelling, improving indoor air quality and stopping or preventing condensation problems from occurring. Perfect for retrofit installation into existing properties, the HomeDry PIV Loft Unit is very easy to install.
A single fan unit mounted in the roof space supplies fresh, filtered air into the dwelling via a central hallway or landing. This creates a slight positive air pressure which forces stale, moisture-laden air out via fortuitous air gaps and natural leakage.
The ceiling diffuser has been aerodynamically designed to direct incoming air along the ceiling where it mixes with warm, buoyant air before re-circulating downwards, thereby ensuring a more even thermal gradient between the floor and ceiling.
Due to its ease of installation, the HomeDry PIV Loft Unit is designed primarily for properties that benefit from a well ventilated loft space.
Features and Benefits
Energy Saving : Supply-air taken from the roof space is slightly warmer than outside air so can provide some energy saving compared with a conventional extract system.
Simple and Easy Installation : Requires only a single electrical connection. Does not require ducting through the interior spaces.
Low Running Costs : With its DC fan, the HomeDry PIV Loft Unit is extremely energy efficient, costing from as little as 1pence a day to run.
Minimal Maintenance : Replacement of the long-life filter is only required every 5 years (if extremely soiled) otherwise you can hand wash in warm water and hang-dry.
Aerodynamically designed diffuser : The diffuser is designed to direct incoming air along the ceiling, thereby mixing with, re-using and re-circulating high level warm air.
A full installation guide is supplied with each system. The ceiling must be as airtight as possible to minimize re-circulation of air from within the dwelling. Roof space must be ventilated from outside, e.g. by eaves vents.
The HomeDry PIV Loft Unit incorporates an extremely low wattage DC motor, minimizing energy usage and should be installed to a fused spur (using a 3 amp fuse).

HOME DRY condensation vents are designed to reduce condensation thanks to the centre core.
Condensation is fast becoming the most common form of unwanted dampness in homes and buildings.
By fitting the innovative HomeDry vent, the problems will be solved quickly, cheaply and efficiently.
Thanks to the central CORE filter, the HomeDry vent allows condensation and moisture laden air to escape the property, as the psychrometric conditions on the inside of the building are different to that on the outside.
The difference in the conditions within a property will result in a vapour pressure differential from inside to outside, which is the driving force to allow vapour dispersion.
Our new HomeDry vent stops annoying draughts, reduces heat loss and traffic noise with absolutley no energy consumption it is perfect for combatting problems with mould and algae growth.
The HomeDry vent is designed to reduce condensation thanks to the central CORE:
The PAM TWIN is a fully automatic waste water pumping system suitable for pumping surface and/or ground water to a higher level when gravity drainage is not possible and/or economical to install.
The system is suitable for installing either at the initial building stage or retro fitting to existing buildings and can accept waste from car parks, car washes, floor areas, down pipes, cavity membrane systems or similar.
The system consists of a polyethylene tank with single automatic waste water submersible pump. It can accept surface and/or ground water through the grille located on the top of the unit, or can be cut to accept drainage channel.
A 9v float switch alarm and full fitting kit are included.
NUMBER OF PUMPS
PAM Ties would always consider a battery backup system and a regular maintenance programme to be best practice in all below ground waterproofing situations.
FACT : The PAM Basement pump can discharge 120 litres / min to a maximum head of 7 metres!
PULL OUT STRENGTHS IN KN
Expand the tie into both the inner and outer leaf to the recommended torque.
Suitable where the walls are sound. Are simple to install and inner leaf connection can be checked before the outer leaf is tightened. Unsuitable for timber frame buildings.
Domestic dwellings, small commercial buildings up to three storeys, (not greater than fifteen metres in height) comprising of brick or blockwork of similar thickness.
Our PAM Mould Removal Kit contains everything you need to successfully eradicate mould (including black spot mould - Aspergillus Niger) and associated problems.
This kit contains
All houses contain mould spores no matter how well they or when they were constructed. These are normally dormant and harmless, but under certain conditions these will become active. This will lead to the ugly black spot mould (Aspergillus Niger for those of you who like Latin) appearing on surfaces.
It doesn't take much to kick this process off. The mould spreads on walls, surfaces etc and the mould spores can become airborne which as well as smelling musty can also be a seriously detrimental to health. Black spot mould can also damage your carpets and clothes.
You can read one of our many articles on this problem right here on our blog.
What causes Aspergillus Niger?
Essentially, mould thrives on dampness. If you have damp in your home this is most likely caused by condensation although burst or leaky pipes, penetrating damp or rising damp can also be a cause. Home dampness is on the increase, and the number one cause is condensation caused by poor ventilation. Again, you can read about condensation and how to eliminate it here on our blog.
Mould and how it affects your health
Even small amounts of mould and mould spores can affect your health. It can lead to or further exacerbate asthma and other respiratory conditions and can also contaminate your food. It can affect adults and children.
Who is affected?
Some people are more sensitive to mould than others, such as babies and children, the elderly those with existing skin problems, such as eczema and those with respiratory conditions, such as allergies and asthma if you have a weakened immune system you should also avoid mould.
