Heatlok HFO

In 2017, Demilec introduced the innovative Heatlok HFO, an advanced zero ozone-depleting, ultra-low global warming potential (GWP) and high renewable/recyclable content closed cell foam. To truly be transformative, Demilec does not just meet industry-changing blowing agent requirements, Heatlok HFO also delivers industry-leading R-value, differentiated performance criteria, and superior product yield. Heatlok HFO shatters contractor and builder expectations and redefines performance for the closed cell spray foam category.
Demilec worked through many iterations to ensure the product exceeded code and provided builders with a strong environmental story for their customers while not adding cost over and above their existing spray foam package. Additionally, Heatlok HFO High Lift, with a 7.5/in R-value, can achieve an R-49 in 6.5in, making it ideal for vaulted ceilings. By going beyond expectations, Demilec delivers product excellence for builders and contractors, creating a product that provides superior performance in all key metrics: R-value, yield, dimensional stability and compressive strength. Building codes are increasingly calling for tighter building envelopes and higher levels of energy performance to meet evolving sustainability goals. Heatlok HFO is a closed cell spray foam insulation that delivers on both of these crucial requirements.

Consumer Benefits:

A high-performance home is comfortable, healthy, durable and efficient. Insulating with Demilec Heatlok HFO spray foam, in conjunction with other high-efficient building materials, is key to achieving these advantages and building a better home. Benefits to homeowners include:

Comfort: reduce drafts and outdoor noise pollution, and help keep temperatures more consistent throughout the home.

Healthy: minimize the amount of dust, allergens, and pollutants from entering the home, and create an effective radon and soil gas barrier.

Durable: improve structural and racking strength, increase wind uplift resistance, and provide resistance to flood damage.

Efficient: reduce stress on HVAC and mechanical systems, while helping to save up to 50% on heating and cooling bills.

Builder and Contractor Benefits:

Many builders have already begun to leverage the energy efficiency, sustainability, resiliency, speed of installation and cost which Heatlok HFO brings to the job site. Looking to the future, it will only get more difficult for builders to meet code and sustainability demands/requirements without using a product like Heatlok HFO.
