Glass & Glazing FAQ

Why should I upgrade my glass/windows?

There are a number of reasons why you should have Energlaze upgrade your glass or windows. Firstly, Government Building Regulations require us to use energy efficient products that help to reduce CO2 emissions and protect the environment. Energlaze technology ensures that your new glass will be the most energy efficient window glass available. Using Energlaze is an easy and efficient way of complying with these regulations whilst offering a number of other benefits:

  • Free Solar Gain – Energlaze uses advanced coating technology to capture free energy from the sun to help heat the home.
  • Thermal Insulation – The advanced inner coating reflects heat back into the room, meaning less energy is needed to heat the home to the desired temperature.
  • Eliminate Condensation – Energlaze helps to virtually eliminate internal condensation, reducing draughts and cold spots in and around the windows.

Do you retrofit one window?

No. We recommend that you start with a minimum of three windows so you can really feel the benefit of our Low-E-Plus heat retaining glass.

Where is the glass manufactured?

Our IGU’s (Insulated Glass Units) are manufactured in Ireland to the highest EU Standards.

Do you supply and fit secondary glazing?

No. We recommend New Fineo Glass for sash windows. Fineo is the same width as single glazing with the insulating properties of triple glazing.

Do you install triple glazed units?

No. We specialise in heat retaining double glazing which is as energy efficient as triple glazed units.

What are U-Values and why are they important?

U-values determine the thermal efficiency of a material. The lower the U-value the less heat is lost. For more information on U-values click here.

Do you dispose of my old glass?

Yes, all debris is removed from site & recycled where possible. The fitting team will lay down dust sheets where they are working & clean up once they are finished.

Is the coating on the glass permanent?

Yes, the coating is permanent and hermetically sealed with the glass unit so will last the lifetime of the window.

Will the coating effect the appearance of the glass?

No, the coating on Energlaze IGU’s is completely transparent and microscopically thin. It is designed to match the rest of the glazing in your house.

If the glass lets the sun in, does it let anything out?

The glass has a very thin, transparent metallic coating that reflects heat back into the room, rather than allowing it to escape through the windows. At the same time it allows heat from the sun to pass through the glass to warm the room, meaning it takes less energy to maintain a warm, comfortable home.

I have double glazing, does this mean my windows are energy efficient?

Of course all old, uncoated, double glazing offers a limited level of heat retention. However, Building Regulations now state that an energy efficient window glass must be used in the replacement windows and a double glazed unit containing Energlaze double glazing units is up to 70% more thermally efficient than standard non-coated double glazing

I have window alarms, do I need to do anything before installation?

Yes. If your alarm has sensors on the window or glass, these will need to be removed. In some instances, you will need to have your home security provider remove these for you. Energlaze fitters cannot remove them on the day of fitting. Failure to remove sensors will delay your fitting.

What can I do if my windows have condensation?

Solar FAQ

How will Energlaze determine what size system I need?

Our Energy Consultants will advise a system size based on your energy consumption by reviewing previous electricity bills. They will also establish how many panels will fit on the roof of your house or garage. Ground-mounted systems are also available.

What are the dimensions of a solar PV panel?

Each panel is 1640mm (height) x 992mm (width) x 40mm (depth).

How do I apply for an SEAI Solar grant?

Our Energy Consultant will assist you with the online application for an SEAI grant or they will leave a step by step guide with you if you choose to apply at a later date. For more info on grants click here

How long is my solar PV system guaranteed for?

The panels have a 20 year guarantee and a 30 year lifetime warranty. The BPE and Sonnen inverters have a guarantee of 5 and 10 years respectively.

How much maintenance is required for a solar system?

Our systems are low maintenance, they require a service once every 5 years.

I have velux windows, can I still get a solar PV system?

Yes. Our team will take measurements and advise on the best way to apply the panels to your available roof space.  If the available area on your roof is not large enough for solar panels, Energlaze can also provide ground-mounted systems.

Do I need to get a BER cert before or after installation?

If your home does not have a building energy rating, you will need to have one done in order to assure you will reach a minimum of C3 post works. A BER is carried out post works also and this cost is included in the grant amount.

Can I get an electric vehicle charger?

Yes, as part of a full solar PV system.

What is the freephone Huawei Solar customer support number?

If you have a Huawei Solar PV system you can avail of freephone support via Huawei Technical Assistance Center

Insulation FAQ

I need my attic insulated, does Energlaze provide this service?

Yes, but only as part of a multiple upgrade package. Our team can advise you on the best upgrades specifically suited to improving your home’s BER

How long does a full external wrap take to complete?

External wrapping can take up to three weeks, weather depending. Rain will delay fitting time as each layer needs to dry completely before the next layer is applied. Summer is the perfect time to insulate your home, by taking advantage of longer dry spells to complete the installation faster. Your home will benefit from the added insulation in the summer months also by keeping you cooler, for longer.

How do I know if my home has a cavity wall?

If your external walls are more than 300mm in thickness, then it is possible that there is a cavity. Another way to check is if your electricity box is on an external wall, you may be able to see the wall cavity to the side of the box. Finally, the only way to know for certain is we drill a small, inconspicuous hole in a wall and use a camera probe to view the cavity.

My house is damp, will insulation help?

You need to discover the source of the damp first to ensure insulation does not trap even more moisture it could be:

  • Poor ventilation
  • Poor glazing
  • Rising damp because there is no Damp-proof course (DPC)

Heat Pumps FAQ

What is a Heat Pump?

Heat pumps are an energy efficient way to convert energy (the cold air outside your home) into heat inside your home, similar to how a fridge extracts heat from inside. Every unit of electricity used in the process yields roughly four units of heat for your home. In well insulated homes, heat pumps are inexpensive to run and a great alternative to fossil fuel based systems.

Is my home suitable for a Heat Pump?

Why are grants available for heat pumps?

Heat pumps are a sustainable and renewable way to heat your home. Grants have been discontinued for oil and gas boilers to accelerate the move away from fossil fuels and towards renewable forms of heating. Learn more on our grants page here.

Am I eligible for an SEAI Heat Pump Grant?

To qualify:

  • The house must be well insulated (or ‘heat pump ready’ as the SEAI refers to it). SEAI insulation grants only apply to homes built before 2011.  The SEAI points out that uninsulated homes built more than 30 years ago may require substantial and costly upgrades to qualify for a heat pump system grant.
  • Before applying you will need to appoint an SEAI-registered Technical Advisor to carry out a Technical BER.
  • All homeowners, including landlords, whose homes were built and occupied before 2021 can apply. This is defined as the date your electricity meter was installed.

What is the grant amount for an Air-to-Water heat pump?

€6,500.00, including €200.00 towards the cost of the Technical BER.

Why the focus on ‘fabric first’ for heat pumps?

For heat pumps to operate efficiently, they should only be installed in sufficiently insulated homes. Homes that are not properly insulated would find their bills to be much higher than expected. To ensure that a home is “heat pump ready” the SEAI has introduced a process whereby homeowners need to have a technical BER assessment carried out on their property to assess heat loss from the home. The heat Loss indicated during this assessment must be no more than 2 W/K m2 . An independent SEAI registered Technical Advisor will carry out the required technical assessment to determine the suitability of your home.

At the point of applying for a heat pump grant the homeowner is required to upload the Technical Assessment document detailing the home’s eligibility. A grant of €200 towards the  cost of the technical BER is included in the heat pump grant after the works are carried out.

How can you improve the Heat Loss Indicator of a poorly performing home?

The technical BER report will outline the measures needed for each individual home. It is likely to include recommendations such as the installation of high performance glazing, new windows and doors and or insulation. The SEAI offers grants towards insulating your home (external wall wrapping, internal dry lining and cavity wall insulation).

Please note, that as you increase the insulating measures in your home, you are also making it more airtight. You will need a ventilation strategy for the home, which may sound contradictory, but air flow is extremely important in your home.

Are Heat Pumps costly to run?

No, if your home is sufficiently insulated and airtight, heat pumps are far more economical to run than traditional forms of heating such as oil and gas boilers.
