FAQ

Yes. The connection can be disconnected if needed without damaging the components.

No. Both the seal and the secure connection are integrated into the Click-Seal ring, eliminating the need for additional sealing materials.

No special tools are required for the connection itself. Only standard duct preparation tools, such as the Air Excellent circular cutting tool, are recommended for clean duct cuts.

Manufacturers like Ubbink offer ducting already pre insulated so no need to do anything its already done for you; you can also purchase ISO sleeves to wrap semi rigid duct to ensure it complies with the regulations.

When the duct is inserted correctly, you will hear and feel an audible click. This confirms both the mechanical locking and airtight sealing are engaged

• You can check the ducts ATC rating, Air Tightness Classification:  only use duct rated 1. You can also do a Sniff Test on the duct, cheaper ducting emanates a plastic smell, this smell is transferred into the house something you do not want, on high quality ducting there is no smell.
You can also do the “Tug Of War “Test, let the manufacturer demonstrate how the system goes together and try to pull it apart cheaper systems will not maintain the connection, remember once this is in your ceilings and walls you do not want it to come apart.

Similarly, if you ever require you duct cleaning the integrity of the duct must be maintained whilst being cleaned, and not come apart once installed, using cheap ducting with poor connectivity could result in a disconnection which can be catastrophic and require major work inside your home to fix.

There are several regulations in the UK that cover not only MVHR but all ventilation systems types, the main driving regulations revolving around ventilation are Part F, Part O & Part L with other regulations that must also be considered Part B ( Fire Safety and Part M Access to and from buildings )

Coarse pre-filters can be gently vacuumed or washed to remove dust. High-grade pollen or HEPA filters must be fully replaced.

There a 2 ways in which MVHR units boost, the first is done via a Humidity Sensor located within the unit, this senses humidity spikes and automatically speeds the machine up to remove the increase in humidity, once the levels have returned to normal the unit itself returns to its trickle speed setting, the second way is via a boost switch or control located on a wall normally in the kitchen area, this is a manual input by the homeowner, this will set the MVHR unit to next available speed and will normally run on a timer for around 15 minutes and at this point it will return to its trickle speed.

Reducing the size of ducting has many implications in air velocity and air resistance , this can create lots of issues with the performance of your unit.

MVHR units will perform as intended, with a well designed and installed ducting system, if the ducting system is not designed and installed well it will cause long lasting problems.

No, an MVHR system will extract from all wet rooms so no need for Bathroom fans or Kitchen fans .
 

Ubbink Eaves Guard need to be overlapped a minimum of 100mm when fixing multiple lengths. They are designed to be overlapped so thay can be fixed for all roof lengths and can be cut to size. 

Ubbink Eaves Guard is fixed mechanically using stainless steel nails fixed at 400mm centres into the rafters or fascia board. Any overlaps of the product need to be a minimum of 100mm. The Eaves Guard can be cut down to size to fit the roof design. 

The Eaves Guard length can easily be cut down to size to make it universal for all eaves details and sizes. 

The roll our rafter tray is designed to ensure that wool based insulation at the eaves do not block the airpath from the eaves ventilator into a cold roof space. Thwe width of the rafter roll required is based on the roof pitch and insulation thickness. 

Many roof constructions require low level ventilation. An over fasica vent can guarantee a free area ventilation of 10,000mm²/m or 25,000mm²/m to comply with BS5250:2021. Fascia vents are often the most unobtrusive ventilation products and minimise the chance of stangant air pockets due to their continuous apllication on the eaves. 

Bird combs are recommneded when profiled tile such as pantiles and romans create gaps at the eaves that allow access to nesting animals. A bird comb can be fitted to close the gap created by the profile of the tile and stop the risk of animal ingress. 

Yes. The Haelix valve can be used for both air supply and extract, helping simplify specification and reduce the need to stock separate valves.

The standard Haelix range is available in two designs: Rondo, with a round shape, and Quadro, with a square design. Both feature a modern, low-profile appearance.

The Haelix is a stylish, low-profile ventilation valve designed for both air supply and extract applications in residential ventilation systems.

Yes. The Ubiflux Compact W200 is compatible with CO₂ sensors and humidity (RH) sensors. These accessories enable demand-controlled ventilation, allowing the unit to automatically adjust airflow based on indoor air quality and occupancy levels.
 

No. Measuring just 560 x 660 x 315 mm, the Ubiflux Compact W200 has been specifically designed for homes where space is at a premium, making it one of the most practical solutions for compact residential applications.
 

The Compact W200 has 2 filters, these are constantly removing Airbourne pollutants , the filters can be changed according to the environment, for example; urban areas require a different kind and grade of filter compared to rural areas, the air coming into your house is not only warmed nut also filtered fresh. This helps create a healthier and more comfortable living environment.
 

The Ubiflux Compact W200 extracts warm, moisture laden air from all wet rooms in your home, IE kitchens Bathrooms, Utility rooms  and shower rooms, the only element that is retained within the unit is the heat, all the other components like moisture, odours and so on are expelled to atmosphere, at the same time as we extract air we also supply air to habitable rooms, Living rooms and Bedrooms, the incoming supply air is filtered and once inside the unit is warmed utilising the heat retained during the extract process, the Compact 200 will recover around 90% of the heat that would normally be expelled outside and returns it back clean and fresh into the habitable rooms.
 

The Ubiflux Compact W200 can be configured with a range of accessories and filtration options, including:
  • CO₂ sensors
  • Humidity (RH) sensors
  • Control switches
  • Frost protection preheater
  • G4 filters
  • F7 filters
  • Carbon filters

These options allow the system to be tailored to specific project and indoor air quality requirements.
 

The Ubiflux Compact W200 is available in both left-hand and right-hand configurations, giving installers greater flexibility to suit different property layouts and ducting requirements.
 

MVHR units will require servicing , the replacing of the internal filters is only part of what should be covered within a unit service, ideally the MVHR should have the Heat Exchanger removed and the unit cleaned internally , the condensate drain should be checked for signs of leaks and blockages, the ducting should be checked and cleaned where possible, the ceiling valves should be removed and cleaned and if required the system should be re commissioned and balanced .

No, you do not need adhesive for foam ducting, it should be supplied with connectors and joiners, these are easy to use, quick to install and when clipped together ensure an airtight seal.

Aerfoam (Foam ducting) meets all the ventilation requirements in relation to insulation levels , therefore stopping condensation build up.
 

Wall Brackets should be placed every 500 mm to support the Foam ducting (Aerfoam).
 

Aerofam (Foam Ducting) is installed by sliding onto the spiggot and connecting with a suitable aerfoam connector.
 

Aerfaom needs no maintenance.
 

The Ubbink heat pump kit supplies all the components to connect your heat pump to the external environemnt: 1M length ducts, connectors, bends and airtight seals 

Heat pumps need ductwork to effectively distribute the heated or cooled air via extract and supply sources to the outdoor environment. We also supply the components individually in our Aerfoam range.

Yes. Roofing membranes should comply with the relevant British Standards to help meet UK Building Regulations.
Our MultiVap Plus and MultiVap Super membranes are tested to BS EN 13859-1, achieving UKCA and CE certification. They also support compliance with:
  • BS 5250:2021 – Management of moisture in buildings
  • BS 5534:2018 – Slating and tiling for pitched roofs and vertical cladding

 

Roofing membranes are designed to provide temporary weather protection during construction. However, they should not be left exposed for longer than the period specified in the installation instructions, as prolonged exposure to UV light and the elements can affect performance. Always install the final roof covering as soon as practicable which is advised to be no more than 12 weeks, in accordance with STA Advice Note 18.

 

Vapour permeable roofing membranes are commonly used in modern pitched roof construction because they allow water vapour to escape from the roof structure while preventing the ingress of wind-driven rain and snow. This helps reduce the risk of condensation and contributes to a healthier, more durable roof system. The correct membrane should always be selected based on the roof design and in accordance with the relevant British Standards.
 

The correct membrane depends on your project's wind zone requirements, as defined by BS 5534.
  • MultiVap Plus – Suitable for Wind Zones 1–3 (150gsm)
  • MultiVap Super – Suitable for Wind Zones 1–4 (170gsm)
For more information and technical specifications, visit our Roofing Membranes product page 
 

For help with installation please head to our Membrane Brand page.

UKCA and CE markings demonstrate that a product has been tested and assessed against the applicable performance requirements. For roofing membranes, this includes testing to BS EN 13859-1, giving specifiers, contractors, and homeowners confidence that the product meets recognised quality and performance standards.
 

Yes, semi-rigid Ducting can be bent, however the amount you can bend it is restricted to maintain a smooth radius or curve.

For insulating Semi-rigid Ducting, it depends on where it is located, the regulations state that all duct if installed in unheated areas IE a loft, must be insulated, the insulation value must be 0.04w/mk or lower or by using an insulated wrap the semi rigid duct can have an insulation layer around it of 25mm .

If you install semi rigid duct elsewhere outside of a cold area it does not require insulating.

Good quality ducting like our Air Excellent system does not need any other sealants, any ducting with ATC1 (2 sizes certified ATC2)  rating is airtight already.

Back in the early 2000`s it was common to use tape to join ducts along with a non-hardening sealant , this is no longer the favoured option, ducting manufacturers like Ubbink manufacture ducting connections that will provide an airtight seal without using tape or sealant.

The size of the semi-rigid ducting is proportionate to the amount of air required for example, if the house/property demands a high volume of air being supplied and extracted then this may require larger ducting or even double duct runs., all of this is calculated at the design stage .
In a nutshell , the design determines the air volumes, it the air volumes are high you need larger ducting , if the air volumes are low you can use smaller ducting.
 

Semi rigid ducting should be supported every 500 mm , the ducting should not sag as condensation can form in any dips or traoughs and cause problems.

Yes, Semi rigid Ducting is flexible, however the ability to bend it too far is restricted, air does not like to go around corners so limiting the amount of flexibility is key .

As of the creation of BS8612 in 2018, all new build projects require dry fixings for ridge, hip and verge systems instead fo the previous wet cement based fixings. 

Dry fix systems can be retrospectively installed but would usually require the primary roof covering to be removed in that area. It would be best to consult the Ubbink Technical Team for installation advice for retrospective installs. 

The key benefit of using an ambi-hand product comes when purchasing the product as the left and right units do not have to be quantified. It also reduces the risk of the incorrect handing being fitted on site. 

As the dry fix kits are not reliant on ony wet trades or adhesives, the product can be installed in all weather and temperture conditions. 

Yes this product is suitable for both new build and retro fit due to the unique starter unit which can be installed before or after the gutter installed.

The Ubbink dry verge has an integral water drip channel within the unit to minimse the risk of water staining.

With the Ubbink Solar Flat Roof Mounting System FRS60, you can install solar panels on the flat roof without breaking through the roofing material. The system consists of plastic tray supports that you fill with ballast after installation on the roof. This makes the process quick and easy, without the risk of leakage. The ready-made frames for the flat roof mounting system offer maximum flexibility in placement, allowing you to easily accommodate roof penetrations, skylights, and other objects on the roof.

Ubbink offer a range of insulated and uninsulated flat roof terminals where most extraction systems can be attached with a wide range of spigot sizes to cater to most ducting diameters. 

We provide an installation insruction for our OFT's, we are often asked  for extra advice on the EPDM roof covering;  it should simply adhere the flashing with rubber glue (or similar) also use more EPDM material to flash over, up to the stainless steel section of the collar to ensure fully watertight but not mandatory

There are a number of Ubbink products that can be used to ventilate a flat roof. Due to the complex design of flat roofs, techncial advice should be sought to determine the best ventilation strategy. 

Ubbink have a range of flat roof products dependent upon roof covering and roof construction. It is best to seek technical advice to determine the best products and strategy. 

The Ubbink OFT ventilators can be retrospectively fitted and follow the same installation to manufacturers' fixing instructions. As the primary roof covering will need to be cut away, it is worth contacting their relevant technical team to determine the best way to re-seal their product to the Ubbink ventilator. 

Due to the 25,000mm²/m free area ventilation requirement to comply to BS5250:2021, the OFT2 160mm is the only suitable ventilator for flat roof ventilation. These will need to be spaced at 750mm centres or between each joist space if cross-flow is not apparent.

Our vision of sustainability is that we want to develop into a circular brand. This means we want to look at how we can integrate sustainability and circularity principles in all aspects of our business operations. This is a continuous process of analysing, adapting, learning and improving. We want to be transparent in what we do and what we achieve. For example, by looking at our business processes, production processes and HR processes and, together with our stakeholders, looking at the impact we have as a company and where we can improve.

We have made a conscious decision not to prioritise one stand-alone initiative over another. We have incorporated sustainability into our entire business operations by integrating it with specific business strategies. For example, our HR sustainability principles are part of our HR strategy. And our principles concerning health and safety are included in our Health & Safety strategy, and rolled out to the entire group from there. This means we can be simultaneously active in multiple areas and make rapid progress. It also fits our view that sustainability is not a stand-alone issue but is actually an integral theme of our organisation.

This is a very important point for our theme of “our solutions”. It is important that we look at sustainability and circularity and make informed decisions, particularly during our design process. We have a clear process for this. Right from the start, when drawing up the specifications of a new product, we ask questions about sustainability and circularity. For example, in what parts can we use recycled materials. Or where can we source the parts that we do not produce ourselves? And whether the proposed supplier meets our purchasing conditions. We will start using so-called Life Cycle Assessments as part of our design process in 2024. This means we will analyse the environmental impact of new products during the design phase. And if we see opportunities to reduce that impact, we will do so in advance rather than afterwards.

We started a baseline measurement in 2023, taking the year 2022 as a reference. We collect data again every year and compare it with the data from 2022, our reference year. In the meantime, we determine the goals we wish to achieve for important, measurable components: our Key Performance Indicators (KPIs). As a result we can measure and communicate our progress every year.

Ubiflex has been tested up to 80°C and  achieved 'no leakage' when tested for watertightness. This means that the product is fit for purpose for all UK weather conditions. We do recommmed the product is installed in dry conditions and if used with the High Tack adhesive is installed at tempertures above 5°C. 

Ubiform + and Ubiflex Finio are self adhesive products. The standard range comes with ancillary products to adhere the flashing to the roof covering such as tigh tack sealant, please see fitting instrcutions for further details.

Yes! Due to being lightweight and it can be installed in full rolls length this range is quick and easy, saving time on site and projects.

Many lead alternatives are significantly lighter than lead making installartion quicker and easier. They offer very low re-sale value and reduce the chance of on-site thefts. They also do not have chemical coatings offering a positive environmental impact. 

Many materials can be used as a lead alternative and offer benefits such a a lighter weight, no re-sale value, less toxicity and improved reyclability. The Ubiflex range has been constructed using a mixture of bitumen, polypropylene and aluminium.  

A lead alternative is a product that can be used in the same applications of lead in typical roofing details, The products are made from materials which hold the same weather resistant properties as lead but can offer weight, social and envireonmental benefits. 

Yes, windows and doors can be opened with a balanced Ventilation system, but there is no need to do this, the MVHR system is supplying fresh filtered air into your home. 

 In modern homes maintaining good air quality is crucial for the occupants and the buildings fabric, with MVHR systems ensure the system is designed by a professional body, that the system is installed by competent trained installers and then to finalise only use competent trained people to commission the system.
Following on from this ensure regular servicing is done to maintain the unit’s efficiency and overall performance this will ensure that the indoor air quality is also maintained.

The ventilation requirement is calculated  on room sizes and occupancy, approved Doc F gives us all the data required to calculate this.
 

to prevent cold air from entering the home, keep all windows and doors closed, avoid trickle vents in windows and use MVHR as your ventilation choice
 

A healthy indoor climate is a climate free of moisture, odours and other household pollutants like smoke

An air distribution box or manifold is a box with multiple outlets that the semi rigid system duct can be connected, there would always be 2 manifolds or D boxes on a system, one connected to the supply one connected to the extract.

For bathroom extracts, we offer a variety of tile vents to suit your needs, including the UB19 with a felt sleeve and adaptor, the UB41 (a full terminal with adaptor), or the UB16 with a stepped adaptor.
For kitchen extracts, we recommend using one of our stack terminals based on your ducting size, UB46, UB47, UB48, or UB49.

We offer a comprehensive range of roof vents, tile vents, and slate vents designed to suit most roof types and roofing materials. Our selection includes solutions for concrete roof tiles, clay roof tiles, slate roofs, interlocking tiles, plain tiles, and flat roofs, helping homeowners, contractors, and roofing professionals find the right ventilation product for their project.
Whether you need roof space ventilation, a vent for bathroom or kitchen extraction, or a solution to help prevent condensation and moisture build-up, we have products available in a variety of profiles and airflow capacities. Many of our vents are designed to blend seamlessly with existing roof coverings, providing effective ventilation while maintaining the appearance of the roof.
If you're unsure which vent is suitable for your roof type, our product specifications and technical team can help identify the best roof ventilation solution based on your roof covering, ventilation requirements, and extraction needs.

For a seamless and aesthetically pleasing look, our in-line tile and slate vents are a great option. We offer a variety of in-line profiles to match popular roof tiles (UB62), clay tiles (UB8), and slate roofs (UB11), giving you plenty of choices to suit your project.
Please note: Some in-line profiles have a lower free vent area, so if you're using them for extraction, ensure they provide adequate ventilation.

Check the back of the tile as some manufacturers will state the profile, if you are unsure please contact a roofer or send Ubbink UK a picture with dims and we can help identify.

Check the brand, type, and shape of your existing roof tiles. We offer vents designed to match specific tile profiles, as well as universal options. You can also measure your tiles and compare them to the vent specifications or ask a roofing expert for advice.

To determine the number of vents needed for a pitched or flat roof, divide the total required ventilation area (in square feet) by the free ventilation area of the vent you plan to use. This helps you find the total airflow needed and ensures you install the right number of vents for proper ventilation.
